The BayTech Model 24SII Data Exchange System (DES) is a high  
performance peripheral sharing solution offering versatile and flexible  
connectivity between computers and various peripheral devices.  
Computers may share plotters, modems, and laser printers, as well as  
access other computers to share data bases and transfer files. Cost  
effectiveness is thus achieved through resource sharing among  
multiple users.  
Figure 1 below shows a Model 24SII DES with twenty-four ports  
installed. This application shows eight local PCs, a remote PC using  
the BayTech Tran-x LPT-460 high speed parallel/serial converter, and  
a file server from a LAN sharing a plotter, HP LaserJet Series II  
printer, HP Laserjet Series IIISI printer, and a BayTech BX2448 2400  
bps modem.  
Figure 1

Each port offers high speed data communication with unidirectional  
serial throughput up to 460k bits per second (bps) and parallel speeds  
exceeding 60k characters per second (cps). The Model 24SII  
controller board is used primarily as a data communications bus with  
throughput capability up to 5.5M bps. The controller board allows  
direct communication with the connected modules or routes data to  
the memory module for print spooling. The dynamically allocated  
buffer is available from 1MB up to 16MB.  
Other features of the Model 24SII DES include:  
1)  
2)  
3)  
High-speed data transfer to handle faster computers and  
software;  
Networking between pairs of computers or computers and  
other devices such as modems, bar code readers, etc.;  
Optimum flexibility: You select the right combination of serial  
and parallel ports to meet your needs when ordering, and set  
any port (other than Port 1 of Module 1) as a computer port or  
a printer port;  
4)  
5)  
Expandability so the system can grow with you;  
Compatibility with virtually all computers, printers, plotters,  
modems and other peripherals;  
6)  
7)  
RJ-11/RJ-45 modular connectors on the serial ports are  
optionally available to provide ease in cabling using four  
or eight conductors.  
IBM compatible software to allow for peripheral selection from  
within Windows or graphics programs.

The Model 24SII's generous built-in buffer also saves valuable  
computer time by spooling data until the printer or plotter can receive  
it, keeping your users and computers working full time instead of  
waiting. The spooling buffer on the Model 24SII DES can range from  
0 MB to 16MB in 1MB or 4MB increments. The buffer is field  
upgradable. For printer and plotter sharing applications, you must  
have a minimum of 1MB installed on the initial purchase.  
You may program the following features to meet the requirements of  
your application: the Port Designation (computer or printer) for each  
port, the individual Serial Port Configuration (baud rate, word size,  
stop bits, parity, and XON/XOFF), the Printer Sharing Mode (high  
speed serial modules only), the 4-Wire/8-Wire Operation (M24SII-V07  
high speed serial module only), the Port Logical Names, the Input  
Inactivity Timeout, the Port Select Code, the Port Select Mode, the  
Form Feed Mode, the I.D. Page Message, and the Default Printer  
Assignment. Programming of these features is easily accomplished  
via the menu-driven configuration mode, and all changes are saved  
permanently in non-volatile memory. BayTech provides terminal  
emulation software for this purpose.  
The number of ports on the Model 24SII DES can range from four to  
twenty-four in multiples of four. The actual number of ports is  
determined by the number of I/O modules installed. Each I/O module  
has four (4) ports. The Model 24SII DES can have a maximum of six  
(6) modules installed. You may install additional I/O modules after  
initial purchase to increase the number of ports on your Model 24SII  
DES.  
We will refer to individual ports on the Model 24SII DES by module  
number and port number. The module number for an individual port  
may range from 1 to 6. The port number for an individual port may  
range from 1 to 4, with Port 1 being the top port. For example, we  
refer to the master configuration port as Port 1 of Module 1. Module 1  
inserts to the slot marked "Module 1" on the top of the back panel.

BayTech sells a high speed serial module for the Model 24SII DES  
which supports EIA-422 protocol (M24SII-V07). This allows for long  
cable distances using RJ-11 (4-wire) or RJ-45 (8-wire) modular  
cabling. Use of the BayTech Tran-x LPT-460 or PS-02 high speed  
parallel/serial converter products will allow your PC to transmit data at  
460k bps using cable lengths up to 1000 feet. The same set up will  
allow your cable distance to be up to 4000 feet if your Tran-x card is  
configured to transmit data at 115k bps.  
Figure 2 shows a PC with the Tran-x LPT-460 card and a PC with the  
Tran-x PS-02 external module connecting to the M24SII-V07 module  
via modular cabling.

This section provides basic installation instructions for persons  
knowledgeable in the area of computer equipment installation. In this  
section, we assume that the Model 24SII DES has never been  
configured (i.e., all settings are factory default values). We will refer  
to specific sections in this manual for more in-depth instructions on  
installation, operation, and configuration. Please use the following  
procedure:  
Step  
1
Instructions/Application Questions  
Action/Special Instructions  
Proceed to Step 2.  
Determine how many and what type of  
modules are installed on the Model 24SII  
DES. Identify which modules are serial  
and which modules are parallel. Serial  
modules are labeled as "232" or "422"  
and parallel modules are labeled as  
"PAR" on the back.  
2
Determine which ports on the Model  
24SII DES your devices will be  
connected to (parallel or serial). Also  
determine the necessary Port  
Proceed to Step 3.  
Designations on the Model 24SII DES  
(computer or printer). Computers and  
modems connect to ports designated as  
computer ports. Printers and plotters  
connect to ports designated as printer  
ports.  
3
4
Does your application call for printer or  
plotter sharing between multiple  
computers and just one printer or plotter?  
If no, proceed to Step 5.  
If yes, proceed to Step 4.  
Will your single printer or plotter connect  
to the Model 24SII DES in serial?  
If no, proceed to Step 6.  
If yes, there is no need to reconfigure any  
Port Designations on the Model 24SII  
DES. You will connect your serial printer  
or plotter to Port 2 of Module 1. Proceed  
to Step 7.  
5
For multiple printer/plotter applications,  
you will need to access configuration  
mode and change the Port Designation  
of the ports to which your printers and/or  
plotters will connect from computer ports  
to printer ports.  
Port 2 of Module 1 is the factory  
designated printer port. This is a serial  
port. If you have any serial printers or  
plotters, you may connect one of them to  
this port. If you do not have a serial  
printer or plotter, you will need to  
reconfigure the Port Designation for Port  
2 of Module 1 to a computer port.  
Proceed to Step 7.

Action/Special Instructions  
printer or plotter, you must reconfigure  
the Port Designation of a parallel port on  
the Model 24SII DES to be a printer port.  
Additionally you must reconfigure the  
Port Designation for Port 2 of Module 1  
to a computer port.  
7
Will you be connecting any serial devices  
that will communicate with serial  
parameters different than 9600 baud, 8  
data bits, 1 stop bit, no parity, and  
XON/XOFF handshaking disabled (e.g.,  
2400 bps external modem)?  
If yes, proceed to Step 9.  
If no, proceed to Step 8.

Do you have to reconfigure any Port  
Designations on the Model 24SII DES  
(see Steps 4, 5, or 6).  
If yes, proceed to Step 9.  
If no, proceed to Step 10.  
If you need to reconfigure the Model  
24SII DES with respect to Port  
Designation and/or Serial Port  
Configuration, you will need to access  
configuration mode to make the  
appropriate changes.  
Please see Section 4.6 for instructions  
and then proceed to Step 10.

BayTech provides utility software to assist you in configuring the  
Model 24SII DES. There are three peripheral selection programs  
included to provide easy device selection from text mode, graphics  
mode, or Windows.  
IMPORTANT: Copy the BayTech original diskette onto a blank  
diskette and store the original in a safe place. Read your operating  
system's manual for copying instructions.  
The software utility diskette provided with your Model 24SII DES  
comes with an automatic installation program called INSTALL. You  
must use this program to extract the compressed files associated with  
your unit. INSTALL automatically copies and expands the hidden  
files.

To run INSTALL, use the following procedure:  
1.  
2.  
Insert the software utility diskette into drive A (or drive B) and  
from the prompt type INSTALL followed by ENTER.  
A menu titled "Drive & Directory Definitions" will appear on your  
screen. This menu will display the Source Drive, Destination  
Drive, and Destination Directory. The Source Drive is the  
floppy drive where the diskette is inserted (default is drive A).  
The Destination Drive is the drive where the expanded files will  
copied to (default is drive C). The Destination Directory is the  
directory where the files will copied to (default is BAYTECH). If  
the default parameters do not match your application, you may  
either use the TAB key or a mouse to change fields and type in  
the desired parameters. Once you have entered the  
appropriate values, select "OK".  
3.  
4.  
A menu will appear on your screen titled "Series Definition".  
This menu will contain choices for the type of BayTech product  
you have purchased. Highlight "Model 24 Series" with the  
arrow keys or mouse followed by "OK".  
A menu titled "Printer Selection Programs" will appear on your  
screen. You are given three selections: RAMEXEC, RAMTSR,  
and WNDEXEC. Choose RAMEXEC if your PC runs non-  
Windows programs that do not operate in graphics mode.  
Choose RAMTSR if your PC runs non-Windows programs  
which operate in graphics mode. Choose WNDEXEC if your  
PC runs under WINDOWS. Once you have selected the  
appropriate printer selection program, choose the "OK"  
selection.

The standard Model 24SII DES requires 115 VAC, 50/60 Hz. power  
and comes with a three-prong power cord. Do not attempt to operate  
the unit with a two-prong socket or adaptor. 230 VAC, 50/60 Hz. is  
optional.  
The Model 24SII DES powers-up when you press the power switch,  
located on the front of the unit, to "ON". A green LED on the front  
panel will illuminate when power is applied.  
CAUTION: Power should be turned off anytime cables are to be  
installed or removed. Make sure the power is turned off and the unit is  
unplugged before removing the cover and attempting to make any  
internal changes.

Before you proceed with cabling, determine which type of I/O modules  
you have installed on the Model 24SII. The module type is marked on  
the top of the module panel. Parallel ports have DB-25 female  
connectors. Serial ports have either DB-25 male DTE, DB-25 female  
DCE, or RJ-45 modular connectors. Next, determine what device will  
be connected to each available port, whether the device will be  
connected to a serial or parallel port, and whether the device will  
connect to a computer port or printer port. Finally, you should obtain  
the correct cables to connect your equipment to the Model 24SII.  
NOTE: Any port (except Port 1 of Module 1) may be designated as a  
computer port or a printer port. However, if computer-to-computer  
communication will be required, the computers that will be  
communicating must both be connected to serial ports to allow full  
duplex communication. Printers and plotters are connected via cable  
to user-assigned printer ports on the Model 24SII DES. Computers  
and modems are connected via cable to user-assigned computer  
ports.  
NOTE: If you are interfacing your equipment to the M24SII-V07 I/O  
module, determine if you will use 4-wire or 8-wire cabling.  
Refer to Section 5 and Appendix A to ensure you have all the correct  
cables to fully connect your system.

Connect the proper serial cable between COMx (where x = 1, 2, 3, or  
4) of a PC, or dumb terminal, to Port 1 of Module 1 (the master  
configuration port). All other cables can be connected after the system  
is configured (see Section 8).

From the factory, the Model 24SII Data Exchange System is set up  
with Port 1 of Module 1 (serial) designated as a computer port. Port 1  
of Module 1 is the master configuration port and must always be a  
serial port. Several parameter settings are set only through this port.  
Port 2 of Module 1 (serial) is factory-designated as a printer port. All  
other installed ports are factory-designated as computer ports. You  
may designate in the configuration mode which ports are computer  
ports and which are printer ports if required.  
Other factory-default settings are:  
Input Inactivity Timeout: 20 seconds  
Port Select Code: $SELECT  
Port Select Mode: Mode A (printer selection anytime while  
printing).  
Form Feed Mode: disabled  
I.D. Page Message: disabled  
Port Logical Name(s): set as Device A, Device B, etc.  
Default Printer Assignment: 0 for all computer ports  
(contention mode).

Serial ports power-up from the factory at:  
9600 baud rate  
8 bit word size  
1 stop bit  
no parity  
XON/XOFF disabled  
Printer sharing mode: Bidirectional.  
4-Wire/8-Wire Operation (M24SII-V07 high speed  
serial module only): 8-wire.  
If your application does not match the factory setup of the Model 24SII  
DES, you must first reconfigure the Model 24SII DES by entering the  
configuration mode (see Section 8). For example, if your application  
calls for printer sharing between more than one printer or if you are  
sharing a single parallel printer, you must reconfigure the Model  
24SII's Port Designation. If your application does match, you may  
connect all required cables, apply power, and begin using your Model  
24SII Data Exchange System.

If your application requires that you reconfigure the Model 24SII DES  
different from the factory default configuration, determine which  
parameters must be changed (i.e., baud rate, word size, Port  
Designation, etc.). All features of the Model 24SII DES are configured  
one module (four ports) at a time using a serial terminal or PC  
connected to the master configuration port (Port 1 of Module 1).  
The configuration mode of the Model 24SII DES is menu-driven. The  
configuration menus are accessed by sending a three-character  
sequence to the master configuration port. The three-character  
sequence consists of Control-T, Capital C, followed by the desired  
module number (1 to 6).  
For example, if you wish to configure Module 1, you would send the  
following: <Control-T>C1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If using an IBM PC or compatible to configure the Model 24SII DES,  
first make a copy of the BayTech supplied support software disk and  
store the original in a safe place. (Refer to your DOS manual for copy  
instructions). You will be using the TERM program created by running  
the INSTALL program (see Section 4.2) to change the default  
configuration of the Model 24SII DES. Any terminal emulation  
program supplied by another manufacturer may also be used. Make  
sure your PC is connected to Port 1 of Module 1 with the appropriate  
serial cable. Use the following procedure:  
1.  
From the BAYTECH subdirectory prompt enter:  
a:\term  
The program will respond with an identification block  
and then a configuration menu for the PC COM port.  
You are now in the terminal emulation mode with full  
duplex communication. Any characters you type from  
the keyboard will be transmitted out of the PC COM port  
to the Model 24SII DES. They will not appear on the  
CRT screen. Any characters received from the Model  
24SII DES by the PC COM port will be displayed on the  
CRT screen.  
2.  
Ensure the displayed PC Configuration is correct. If not,  
enter ALT-C to change. For example, if you have your  
serial cable physically connected to COM2 on your PC,  
first type ALT-C followed by the up arrow key and then  
ENTER to have the TERM program switch to COM2.

3.  
4.  
Refer to the upper right hand corner of the screen for  
Handshaking line status. RTS, CTS, DSR, and DTR  
should all be HIGH. The DCD line is not looked at by the  
terminal emulation program therefore its status can be  
ignored. If these signals are not high at this point, check  
to ensure the correct cable is connected.  
Ensure that all red LEDs on the front of the Model 24SII  
DES are off (all ports off-line), and that the green 'power  
on' LED is illuminated.  
You may now configure the Model 24SII DES from the  
PC keyboard.  
NOTE: Keyboard entries must be CAPITAL  
LETTERS. Put your keyboard in the CAPS LOCK  
mode.  
5.  
Depress function key: F1 followed by the module  
number that you wish to configure (1 to 6).  
NOTE: The F1 key in TERM sends the character  
sequence Control-T (14 Hex) followed by the ASCII  
capital C character (43 Hex).  
The main configuration menu for the selected module will appear.  
From this point on, configuration of the Model 24SII DES will be  
accomplished by following the plain-English menus that will prompt  
you. Enter the letter corresponding to the desired operation. Refer to  
the chart provided on the following page for assistance.  
NOTE: Once F1 and the desired module number are sent, the LEDs  
for Port 1 and the ports for the selected module on the front of the  
Model 24SII DES will illuminate and will remain illuminated while you  
are in configuration mode. If only two LEDs illuminate, if no LEDs  
illuminate, or if no menus appear, this indicates that an incorrect  
character sequence has been received. If this occurs, wait for all red  
LEDs to go out and re-send F1 followed by the desired module  
number (1 to 6).

This section is intended to provide instructions on how to set up your  
PC to work with the Model 24SII DES with respect to the BayTech  
software (if you intend to use it) and special considerations to keep in  
mind when connecting your PC to the Model 24SII DES in parallel or  
in serial.  
If you intend to use the RAMEXEC (text mode) or RAMTSR (graphics  
mode) hot key program to select between multiple peripherals, you  
should have both the RAMEXEC and SETUP or the RAMTSR and  
SETUPCFG files copied onto the hard drive of your PC.  
NOTE: If you have a working copy of RAMEXEC (or RAMTSR) from  
a PC that has already configured RAMEXEC (or RAMTSR) for your  
application (i.e., added all the appropriate peripheral device  
selections), there is no need to copy the SETUP (or SETUPCFG) file  
to the new PC. SETUP (or SETUPCFG) is required only if you want  
to make changes to your current version of RAMEXEC (or RAMTSR).  
You would typically add RAMEXEC (or RAMTSR) to your PC's  
AUTOEXEC.BAT file. The RAMEXEC (or RAMTSR) command  
should be located after the PATH command and before any DOS  
shell commands. If you copy the BayTech software onto a  
subdirectory, the subdirectory must be included in your PATH  
command.  
When connecting your PC in serial to the Model 24SII DES, you  
would typically reroute the parallel output to the serial port via the  
DOS MODE command:  
C:> MODE LPTx: = COMy  
(where x=1, 2 or 3; y=1 or 2).  
This command should be part of your AUTOEXEC.BAT program.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
You will also need to change the serial port configuration of your PC  
COM port to match that of the Model 24SII's Serial Port Configuration.  
If you will be using the Model 24SII's factory default Serial Port  
Configuration (9600 baud, 8 data bits, 1 stop bit, and no parity), this is  
accomplished via the following DOS command:  
Mode COMx: 9600,n,8,1,Pꢀ  
where x is the number of the appropriate com port. This command  
should be part of your AUTOEXEC.BAT program.  
EXAMPLE: Suppose you are connecting your PC's COM1 port to the  
Model 24SII DES in serial and you intend to use the RAMEXEC hot  
key software which has been copied to a subdirectory called  
BAYTECH. Your AUTOEXEC.BAT program would need contain the  
following:  
.
.
PATH=C:\...;C:\BAYTECH  
MODE LPT1: =COM1:  
MODE COM1: 9600,N,8,1,P  
RAMEXEC  
.
.
The vertical dots before the PATH command and after the RAMEXEC  
command represent other commands that may be part of your  
AUTOEXEC.BAT file. The horizontal dots shown in the PATH  
command represent other subdirectories that may be part of the  
PATH command.  
NOTE: The DOS MODE command will support a maximum baud rate  
of 9600 bps. BayTech supplies a program, SMODE.EXE, which  
allows you to set your PC com port for serial speeds up to 115,200  
bps. Please see Section 4.2 for instructions to obtain the SMODE  
command from the supplied utility diskette. The instructions for  
SMODE are contained in the README file created by running the  
INSTALL program.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
If you are connecting your PC to the Model 24SII DES in serial and  
are not going to use the BayTech software, you would not need to  
modify your PATH command or include the RAMEXEC command in  
the AUTOEXEC.BAT file.  
If you are connecting your PC in parallel and intend to use the  
BayTech software, you would not include either MODE command in  
the AUTOEXEC.BAT file (unless you are using your com port for  
another application outside the Model 24SII DES).  
If you are connecting your PC in parallel and are not going to use the  
BayTech software, there is no need to modify your AUTOEXEC.BAT  
file. Just print normally after you cable the PC to the Model 24SII  
DES and configure the Model 24SII DES (if required).

Parallel ports on the Model 24SII DES have DB-25 female  
connectors. A straight, DB-25 male-to-male cable is required  
between each IBM PC computer (or compatible) and the parallel ports  
on the Model 24SII DES.  
CAUTION: Some standard EIA-232 DB-25 cables may have Pin 1  
grounded to connector shell. Since there is a strobe line on Pin 1 in  
Centronics protocol, this ground must be removed if the cable is used  
between an IBM PC and the Model 24SII DES in parallel.  
A DB-25 male to Centronics cable is required between each printer  
having a Centronics connector and the Model 24SII DES (same as  
IBM PC to Centronics cable).  
NOTE: BayTech will guarantee parallel data transmission for cable  
lengths up to 15 feet. If you require a longer distance, it is suggested  
that you either use parallel line drivers (such as Tran-x), extended  
distance parallel cables, or consider a serial connection.

The pin assignment for the DB-25 connector is similar to the IBM PC  
parallel connector and uses the following signals for communication:

IMPORTANT: Determine whether the devices which will connect to  
the Model 24SII DES are DTE (Data Terminal Equipment) or DCE  
(Data Communication Equipment). The following devices are  
generally DTE: terminals, printers, computers like the IBM PC. The  
following devices are DCE: modems and some computers.  
If your device transmits data on Pin 2 or receives data on Pin 3, it is

If you are interfacing a DCE device to the Model 24SII DES (DTE),  
you must use a one-to-one or straight cable as shown in Figure 3 on  
the following page. If you are interfacing a DTE device to the Model  
24SII DES (DTE), you must use a crossed cable as shown in Figure 4  
on the following page.  
When using XON/XOFF protocol, it may be desirable to use cables  
with only Tx, Rx and GND connected. Input handshaking lines are  
enabled if nothing is connected allowing the system to operate with  
only Tx, Rx and GND connected.  
CAUTION: Do not attempt to use a serial cable on a parallel port.  
Since an EIA-232 serial port usually carries a potential of +12 and -12  
volts, plugging a serial cable from that port into a parallel port may  
cause damage to the parallel port.

NOTE: Ports on the M24SII-V07 module may be individually  
configured to communicate with either EIA-232 or EIA-422 (default)  
protocol via jumper setting. In addition, you may program individual  
ports to use either 8-wire (RJ-45 - default) or 4-wire (RJ-11) cabling.  
The type of cabling required for ports on this module is determined by  
the Protocol, 4-Wire/8-Wire Operation, and Printer Sharing Mode  
(unidirectional or bidirectional) you are using. Please see Appendix  
A.6 for instructions to configure the Protocol on individual ports and  
Section 8.8.1 for instructions to program 4-Wire/8-Wire Operation and  
set Printer Sharing Mode.  
IMPORTANT: Before you proceed with cabling your equipment to  
this module, you must verify that your equipment supports either EIA-  
232 or EIA-422 protocol. In addition, you must know the connector  
type and the pin/signal definitions for your equipment.  
Ports on the M24SII-V07 module have RJ-45 (8-wire) connectors  
which also accept RJ-11 (4-wire) connectors. Most serial computers,  
modems, and printers do not have RJ-45/RJ-11 modular connectors.  
Therefore, adapters are required to convert from either DB-25 or DE-9  
connectors to modular connectors. BayTech has a complete line of  
RJ-45/RJ-11 adapters and cables that will make your installation quick  
and trouble free. Please see Appendix A.7 for adapter pinouts as well  
as recommended cabling. Figure 7 and Figure 8 on Page 34 are  
drawings of an RJ-45 receptacle and plug.  
There are several possible pin/signal definitions depending upon how  
you have configured the 4-Wire/8-Wire Operation (8-wire or 4-wire),  
Printer Sharing Mode (unidirectional or bidirectional), and the Protocol  
(EIA-232 or EIA-422).  
If you will be using 8-wire Operation, please see see Section 5.5.1.

The Model 24SII DES may have a total number of ports ranging from  
4 to 24, in multiples of 4. Any of these ports (parallel or serial) except  
Port 1 of Module 1 may be configured to have a Port Designation of  
computer or printer. Port 1 of Module 1 must be a computer port.  
Therefore, the Port Designation for this port cannot be changed. The  
Model 24SII DES will automatically convert data from serial-to-parallel  
and parallel-to-serial.  
NOTE: The Port Designation does not allow you to change ports from  
parallel to serial or vice versa. The communication protocol of the  
ports (parallel or serial) is determined by the type(s) of modules you  
have installed.  
NOTE: If computer-to-computer communication is required, the  
designated ports for these computers must be serial ports. If a port is  
to be used for a plotter, it should be designated as a printer port. If a  
port is to be used for a modem, it should be designated as a computer  
port.  
Factory default configuration is Port 1 of Module 1 (serial) a  
computer port, Port 2 of Module 1 (serial) a printer port, and all  
remaining ports (serial and/or parallel) computer ports.

You may configure the number of printer ports on the M24SII-V02  
parallel module to be 0 to 4. If you will be connecting any printers to  
this module, the printers would physically connect to the higher  
numbered ports. For example, if you will be connecting 2 parallel  
printers to a M24SII-V02 high speed parallel module, you would  
attach the printers to Port 3 and Port 4 of that module.  
Factory default configuration for Number of Printers is 0.

To select a specific port in multiple printer applications or when  
computer-to-computer communications is desired, the computer  
sends the Port Select Code (which consists of any ASCII character  
string up to eight characters), the desired module number (1 to 6), the  
desired port number (1 to 4), and a terminating character: 0D Hex  
(Enter/Return) or 0A Hex (Line Feed). We will refer to this entire  
string of characters as the port select sequence.  
For example, if you are using the factory default Port Select Code  
($SELECT) and you wish to select a printer connected to Port 2 of  
Module 4, you would need to send the following port select sequence:  
$SELECT42<Enter/Return> or $SELECT42<Line Feed>.  
The port select sequence is trapped by the Model 24SII DES if valid  
and not passed to the selected peripheral or computer.  
The port select sequence may be sent as a separate ASCII file  
preceding the print job, via DOS batch file(s), as part of a printer  
initialization string, or by using the RAMEXEC hot key software.

If the computer is communicating with 7 bit word size with parity  
enabled, the 8th or parity bit is masked from the Port Select Code  
before it is examined, allowing you to send the Port Select Code with  
odd or even parity.  
Factory default is $SELECT.

In multiple printer applications, you may select printer ports either  
anytime while printing or before the print job only. Mode A is a  
general-purpose mode and allows the computer to select a printer  
anytime while printing by sending a new port select sequence. Mode  
B allows the computer to select the printer at the beginning of printing  
only. In Mode B, the Model 24SII DES will recognize any port select  
sequence in the first 16 characters of the print job only. After the first  
16 characters of the print job have been received, the Input Inactivity  
Timeout period must elapse before the Model 24SII DES will  
recognize another port select sequence.  
Computer-to-computer communication is not affected by the Port  
Select Mode.  
Factory default is Mode A: printer selection anytime while  
printing.

The Model 24SII DES will translate for serial devices using different  
configurations. This allows you to mix-and-match devices having  
different configurations. You may set the baud rate, word size, stop  
bits, parity and XON/XOFF (transmit and receive) for each individual  
serial port. For high speed serial modules, you may also program the  
printer sharing mode to either bidirectional or unidirectional. You may  
program the 4-Wire/8-Wire Operation on the M24SII-V07 high speed  
serial module to be 4-wire (RJ-11) or 8-wire (RJ-45).  
Factory-default configuration on all serial ports is 9600 baud rate,  
8 bit word size, 1 stop bit, no parity, and XON/XOFF disabled.  
The default printer sharing mode for high speed serial modules  
is bidirectional. The default 4-Wire/8-Wire Operation for the  
M24SII-V07 module is 8-wire.

The Input Inactivity Timeout allows the Model 24SII DES to  
disconnect a computer port which has sent a print job when no  
characters are received from the computer for the specified timeout  
period. The input inactivity timeout is effective only for  
computer-to-peripheral communication. For computer-to-computer  
communication, the timeout does not apply, and disconnect occurs  
only manually.  
If the buffer of the Model 24SII DES is filled to capacity, the unit will  
drop the DTR line or send an XOFF to the computer, causing the  
computer to stop sending characters until the buffer can accept more  
data. In this case, the time that the computer is not sending  
characters is not counted as part of the Input Inactivity Timeout.  
Factory default is 20 seconds.

The Model 24SII DES has four Form Feed Modes allowing you to  
determine when form feed occurs at the printers you are selecting: at  
the beginning of printing, at the end of printing, or both. This feature  
is useful when sending DOS files to a laser printer.  
Factory default is no form feed.

You can print a programmable message and the Logical Name of the  
source computer on a separate sheet of paper before or after printing  
any other data. You can enable or disable the I.D. Page Message and  
whether you want it to print before or after the print job. This page  
prints in addition to the form feed. The I.D. Page Message is useful  
for identifying various users' print jobs in the event you have several  
people printing to the same printer frequently, such as in a classroom  
environment.  
Factory default is: "This print job is for:", with the I.D. message

Individual computer ports may be configured to have print jobs sent to  
a specific default printer port automatically. The Default Printer  
Assignment consists of the module number (1 to 6) and the port  
number (1 to 4) that the printer is physically connected to on the  
Model 24SII DES. The Default Printer Assignment may be set to 0 for  
contention mode in which case all print jobs sent from the particular  
computer will be sent to the first available printer.  
Any print job sent without a port select sequence preceding it will  
automatically go to the default printer port upon initial power-up.  
Factory default is 0 for contention mode.

The Model 24SII Data Exchange System allows peripheral (printer,  
plotter) sharing, specific peripheral selection or peripheral contention,  
and buffering of print data. The Model 24SII DES will let several users  
automatically share one printer. In multiple printer applications, it will  
let users contend for the next available printer on a  
first-come-first-served basis or select a specific printer. Data is stored  
in the buffer of the Model 24SII DES and is sent to the printer as the  
printer can receive it.  
From the factory, the Model 24SII DES is preset to allow multiple  
computers to share one printer. If this configuration does not  
correspond to your application, you should make the necessary  
changes to the Port Designations by accessing the configuration  
mode of the Model 24SII DES (see Section 8). For a description of  
the various changes that may be made by accessing the configuration  
mode please see Section 6.  
It is highly recommended that printers or plotters connected to the  
Model 24SII DES be plugged in and turned on at all times while there  
is activity occurring on the Model 24SII DES; however printers need  
not be in the "on line" mode at all times.

In applications where several users are sharing one peripheral  
(printer, plotter, etc.), printer sharing is automatic. The user performs  
his normal print operation; there are no codes to send. Data is  
automatically sent to the printer. The Model 24SII DES can receive  
print jobs simultaneously from all computers and will pass print jobs to  
the printer in the same order in which they were received in the buffer.

In multiple printer applications, the Model 24SII DES gives you the  
capability of sending print jobs to the first available printer (contention  
mode). You may put the Model 24SII DES into contention mode by  
changing the Default Printer Assignment to 0-0 for the individual  
computer port(s) while in configuration mode (see Sections 6.10 and  
8.14). The data is sent to the Model 24SII's buffer and passed to the  
next available printer on a first-come-first-serve basis.  
If your computer is connected to a port configured to default to a  
specific printer upon power-up (i.e., non-zero Default Printer  
Assignment), you may have the Model 24SII DES send a print job to  
the first available printer by sending the Port Select Code (default is  
$SELECT) followed by 00 and a terminating character (Enter/Return  
or Line Feed) prior to sending the print job. Subsequent print jobs will  
be routed to the first available printer until either another port select  
sequence is sent, power is cycled on the Model 24SII DES, or you  
enter the configuration mode.  
The Port Select Code, 00 (zero-zero) and terminating character are  
trapped if they are valid and not passed to the printer.  
A computer connected to a port configured for contention mode upon  
power-up (i.e., Default Printer Assignment of 0-0) may select a  
specific printer by sending the Port Select Code followed by desired  
module number (1 to 6), the desired printer port number (1 to 4), and  
a terminating character. Subsequent print jobs will go to the selected  
printer until either another port select sequence is sent, power is  
cycled on the Model 24SII DES, or you enter the configuration mode.  
The port select sequence may be sent by manually inserting it into an  
ASCII print file, via DOS batch file, as part of a printer initialization  
string, or by using BayTech's RAMEXEC program will send it for you  
when you strike designated hot keys.

To select a specific peripheral in multiple printer/plotter applications,  
the computer sends a port select sequence which consists of the  
user-defined Port Select Code (factory default is: $SELECT), the  
module number the printer is connected to (1 to 6), followed by the  
desired printer port number on that module (1 to 4) and a terminating  
character: 0D Hex (Enter/Return) or 0A Hex (Line Feed). The port  
select sequence is trapped if valid and not passed to the printer.  
For example, if you wish to select a printer which is connected to Port  
2 of Module 2, you would send the following port select sequence:  
$SELECT22<Enter/Return> or $SELECT22<Line Feed>.  
All print jobs sent after you have selected a specific peripheral port will  
be routed to that peripheral port until another peripheral port is  
selected.  
There are two modes for sending the Port Select Code. In Port  
Select Mode A (printer selection anytime while printing), the Model  
24SII DES looks for the Port Select Code anytime. If no Port Select  
Code is received, the data will be routed to the last selected  
peripheral port or to the default peripheral port (if the unit has just  
been powered up).  
In Port Select Mode B (printer selection at beginning of printing), the  
Model 24SII DES looks for the Port Select Code in the first 16  
characters received. If the first characters of the Port Select Code are  
not received within 16 characters, the data will be routed to the default  
printer port. If the first characters of the Port Select Code are received  
within 16 characters and a valid port select sequence is subsequently  
received, the data will be routed to the selected printer port.

A print job starts when the Model 24SII DES receives 3 or more  
characters from a computer.  
In Port Select Mode A (printer selection anytime), a print job is ended  
when no characters are received by the Model 24SII DES from the  
computer for the specified input inactivity timeout period or when the  
computer sends a manual disconnect sequence.  
In Port Select Mode A, when the Input Inactivity Timeout is set to 0  
(zero) seconds, a print job is ended only under the following  
conditions:  
1)  
2)  
3)  
Manual Disconnect: Port Select Code followed by a terminating  
character (Enter/Return or Line Feed).  
Clear Buffer Command: Port Select Code followed by CLR and  
a terminating character (see Section 7.1.6).  
Sending another Port Select Sequence: Port Select Code  
followed by a module number, a port number, and a  
terminating character. This will also start the next print job.

In Port Select Mode B (printer selection at beginning of printing), a  
print job is ended only when no characters are received by the Model  
24SII DES from the computer for the specified Input Inactivity Timeout  
period only.  
CAUTION: The Input Inactivity Timeout should not be set to 0 (zero)  
seconds (disabled) in Port Select Mode B. Mode B operation cannot  
recognize a manual disconnect or clear buffer command until the  
current print job is ended via the inactivity timeout period.  
If the buffer of the Model 24SII DES is filled to capacity, the unit will  
drop the DTR line or send an XOFF to the computer, causing the  
computer to stop sending characters until the buffer can accept more  
data. In this case, the time that the computer is not sending  
characters is not counted as part of the Input Inactivity Timeout.

When a user makes a request to print, the data is sent to the Model  
24SII DES and stored in the spooling buffer (standard 1MB, optional  
up to 16MB). All users may simultaneously input data to this  
dynamically allocated buffer. Therefore, the entire buffer could be  
occupied by data from one user, if only one is active, or the buffer  
could be simultaneously distributed to all users, maximizing buffer  
utilization.  
Print jobs are buffered and put into a queue in the same order in  
which they were sent to the Model 24SII DES. These print jobs are  
then sent to the printer in the same order in which they were queued.  
When a computer port LED illuminates, this indicates a connection  
between the computer on that port and the buffer of the Model 24SII  
DES. When a printer port LED illuminates, this indicates the buffer of  
the Model 24SII DES has connected to the printer on that port.

If a computer wishes to clear the buffer, the computer sends the Port  
Select Code followed by CLR and a terminating character  
(Enter/Return or Line Feed) to the Model 24SII DES.  
This command will only affect print jobs originated by that particular  
computer. Print jobs in the buffer from other computers are not  
affected. The clear buffer command will clear print jobs currently  
queued in the buffer and also a print job in process, if one is printing.  
NOTE: This command will not clear a printer's buffer of data already  
passed to it from the Model 24SII DES.  
The clear buffer command is operable in both Port Select Mode A or  
Mode B. However, in Port Select Mode B, the Model 24SII DES is  
transparent after the first 16 characters are received, therefore the  
computer must wait for the Input Inactivity Timeout to occur before  
sending the clear buffer command.  
The clear buffer command may be sent as a separate ASCII file  
preceding the print job, via DOS batch files, as part of a printer  
initialization string, or by using the utility software.

The Model 24SII Data Exchange System allows pairs of computers  
(or computers and other devices such as modems, scales, data  
collection equipment, etc.) to communicate while other computers are  
sending data to the print buffer and the Model 24SII DES is sending  
data to printers. Full duplex communication allows file transfer with  
many popular communications software packages.  
NOTE: Computer-to-computer communication can occur only if both  
ports communicating are serial. Parallel ports allow one-way  
communication only and will not provide full duplex communication.  
Computers that will be operating with computer-to-computer  
communication must both be connected to ports designated as serial  
ports. For high speed serial modules, the printer sharing mode must  
be bidirectional.

If two serial computers wish to communicate, either computer sends  
to the Model 24SII DES the Port Select Code followed by the other  
computer's module number and port number, and a terminating  
character: 0D Hex (Enter/Return) or 0A Hex (Line Feed).  
If the requested computer is free, the two computers are connected  
with full duplex communication, and an On Line message is sent by  
the Model 24SII DES to the computer requesting the connection.  
If the requested computer is busy, the computer requesting  
connection receives a Busy message from the Model 24SII DES.  
To disconnect, either connected computer first delays two seconds  
and then sends the Port Select Code followed by a terminating  
character: 0D Hex (Enter/Return) or 0A Hex (Line Feed). You must  
wait another two seconds after sending the disconnect sequence,  
before sending any other data such as a print job or Port Select Code.

Do not send both Enter/Return and Line Feed as the terminating  
character. The Model 24SII DES looks for either Enter/Return or Line  
Feed as the terminating character, but not both. If you send both  
Enter/Return and Line Feed as part of the disconnect sequence, the  
Model 24SII DES will not recognize the disconnect sequence unless  
there is a two second delay between Enter/Return and Line Feed.  
If there is not a two second delay prior to sending the disconnect  
sequence and a two second delay after sending the disconnect  
sequence, the entire disconnect sequence will become invalid and will  
be passed through to the other computer device. The timing between  
characters in the Port Select Code should not exceed one second,  
otherwise the Port Select Code will become invalid and the characters  
will be passed through to the device connected to the other computer  
port.  
The Model 24SII DES will respond to a valid disconnect sequence by  
sending an Off Line message to the user requesting the disconnect.

File transfer can be achieved with a computer-to-computer connection  
through the Model 24SII DES as long as the communicating  
computers are each running a third-party communications software  
package. Note that both computers must be serial.  
Following is a partial list of software packages that support file  
transfer: CrossTalk, PC Talk XVI, and Mirror.  
Note that to effectively achieve file transfer, both computers should be  
using the same protocol, e.g., Kermit, Q-Modem, or X-Modem.  
The port select sequence should be sent from within your  
communications package by using a macro or manually typing it out  
so you can see the On Line or Busy message.

NOTE: Using RAMEXEC to select another computer port is not  
suggested. This is because RAMEXEC does not provide full duplex  
communication so you cannot see the On Line or Busy message if  
you attempt to use RAMEXEC to determine whether or not you got  
connection to the other computer port.

Modem sharing can be achieved with a computer-to-computer  
connection through the Model 24SII DES.  
Make the connection to the modem port by sending the Port Select  
Code, the module number (1 to 6) and port number (1 to 4) the  
modem is connected to followed by a Enter/Return or line feed  
character. The model 24 will respond with an On Line message if the  
modem is available or a Busy message if the modem is currently  
connected to another computer port. Proceed with your normal  
modem communications once you receive the On Line message from  
the Model 24SII DES.  
It is suggested that the computer make the connection to the modem  
port on the Model 24SII DES from within your desired modem  
package. You must be in a full duplex mode within your modem  
package. You must also configure your modem package to  
communicate with the same serial port parameters that your computer  
normally uses to print with (i.e., baud rate, etc.).  
A common mistake is to configure your communications package to  
match your modem's serial parameters (baud rate, word size, etc.)  
and not the Model 24SII's serial parameters. Keep in mind that you  
are physically connected to the Model 24SII DES, not the modem.  
The Model 24SII DES will do any necessary serial parameter  
conversions between the computer and the modem.

For example, suppose you want to communicate with a 2400 baud  
modem connected to Port 2 of Module 2 and your PC is connected to  
a computer port set at the Model 24SII's factory default serial  
configuration (9600 baud, 8 data bit, 1 stop bit, no parity, and  
XON/XOFF disabled). Port 2 of module 2 would need to be  
configured to communicate at 2400 baud to match the baud rate of  
the modem. However, you would configure your modem  
communications package to communicate at 9600 baud to match the  
baud rate of the computer port on the Model 24SII DES you are  
connected to. You are now ready to make the connection to the  
modem port through the Model 24SII DES.  
NOTE: The Model 24SII DES does not pass hardware flow control  
lines through the unit. If your modem package requires a change of  
state in either the Data Carrier Detect or Ring Indicator signal lines, it  
is suggested that you use the results codes option on both the  
modem and your modem package when communicating through the  
Model 24SII DES. Please refer to your technical documentation on  
both your modem and your modem package on how to enable and  
use the results codes.  
NOTE: Your external modem should be programmed to have the  
autobaud detect feature disabled. This is done by issuing the AT\J0  
command for Hayes compatible modems.  
Once you have finished your modem session, you must send the  
disconnect sequence (i.e., the Port Select Code followed by  
Enter/Return or Line Feed) to disconnect from the modem port and  
allow other users access to the modem port.

BETWEEN COMPUTER AND PERIPHERAL THROUGH MODEL  
24SII  
When a computer transmits data to a peripheral device through a  
computer port on the Model 24SII DES, the data is received and  
stored in the spooling buffer (standard 1MB; optional up to 16MB)  
which in turn retransmits it to a peripheral device through a printer  
port. During transmission, when the buffer fills, the Model 24SII DES  
will make the computer port's DTR (Data Terminal Ready) line low  
(negative voltage), signaling the transmitting computer that it cannot  
accept more data.  
When the Model 24SII DES retransmits the data to the peripheral  
device through a printer port, and the peripheral device cannot receive  
any more data, the Model 24SII DES will expect to see a low on the  
CTS (Clear-to-Send) line. When the peripheral device can receive  
more data, the Model 24SII DES will expect to see a high on the CTS  
line.  
When the buffer of the Model 24SII DES can receive more data, the  
Model 24SII DES will make the transmitting computer port's DTR line  
high (positive voltage).  
In the reverse direction (peripheral-to-Model 24SII DES-to computer),  
handshaking is the same, but the spooling buffer is not utilized.

BETWEEN COMPUTER AND COMPUTER THROUGH MODEL  
24SII  
When Computer A transmits data to Computer B through the Model  
24SII DES, the data is received from Computer A and stored in a  
512-character buffer which in turn retransmits it to Computer B. When  
the buffer fills, the Model 24SII DES will make the DTR line low to  
Computer A, signaling Computer A that it cannot accept more data.  
When the Model 24SII DES retransmits the data to Computer B, the  
Model 24SII DES will expect to see a high on the CTS line. When  
Computer B cannot receive any more data, the Model 24SII DES will  
expect to see a low on the CTS line.  
When the buffer of the Model 24SII DES can receive more data, the  
Model 24SII DES will make the DTR line high to Computer A.

NOTE: The Model 24SII DES permits XON/XOFF to be enabled or  
disabled by port independently in the receive and transmit directions.  
The description of handshaking functions below considers XON/XOFF  
to be enabled in both directions. If XON/XOFF is disabled in one  
direction, that direction will support hardware handshaking as  
described in Section 7.3.1.

When the buffer of the Model 24SII DES can receive more data, the  
Model 24SII DES will send an XON to Computer A.  
NOTE: For computers sending binary data and using XON/XOFF  
handshaking, the input flow control (Recv) should be enabled and the  
output flow control (Xmit) should be disabled. This will allow any XON  
or XOFF character sent in the binary string to be passed through the  
Model 24SII DES to the receiving device.

You may wish to write your own program for sending the port select  
sequence to the Model 24SII DES instead of manually inserting it or  
utilizing the hot keys provided in BayTech's supplied support software  
program.  
A simple procedure when using word processing programs is to  
create an ASCII file for each printer which contains the Port Select  
Code, the device module number (1 to 6), the device port number,  
and the terminating character. This file could be named PRINTER1.  
When you wish to select a particular device, you simply print this file  
followed by the actual print file.  
Another method is to make the port select sequence the first  
characters of the text. These characters will be trapped by the Model  
24SII DES and will not be sent to the printer. This method will work  
only if the text of the print file is sent in an ASCII format.  
You may also use a DOS batch file to send a port select sequence.  
The DOS command typically used is the ECHO command. An  
example of the ECHO command used to select a printer connected to  
Port 2 of Module 2 using the default Port Select Code is as follows:  
ECHO $PRINTER22>LPT1:.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
This command should be entered in all capitals with only one space  
between ECHO and the $. Please refer to you DOS manual for  
instructions on creating DOS batch files.  
Programs such as Word Perfect and WordStar typically send a printer  
initialization string before any data. The port select sequence may  
also be embedded in this string to select a printer. For example,  
Word Perfect allows you to edit the printer definition file for a specific  
printer by using the PTR command. The port select sequence for the  
Model 24SII DES would typically be inserted prior to any escape  
codes for the printer. Please see the documentation for your  
application package(s) for more information on editing printer  
initialization strings.

If you have a HP 3000 mini computer, you should contact a BayTech  
sales representative to order option #26. When the HP 3000 sends an  
HP LaserJet inquiry command, the Model 24SII DES will then respond  
with the required ASCII 0 (30 hex).  
This option is compatible with all other computer systems.

Configuration changes for the entire Model 24SII DES are made  
through the master configuration port which is Port 1 of Module 1. Port  
1 of Module 1 must always be a serial port to allow configuration to  
occur. The master configuration port has access to the configuration  
of all ports on the Model 24SII DES and can program all options of the  
configuration mode one module at a time.  
A serial computer connected to a port other than Port 1 of Module 1  
may access configuration mode and configure ports on its module  
only. However, configuration changes are limited; several options -  
Port Designation, Port Select Code, I.D. Page Message, and I.D.  
Page Printing Schedule - may be made only through the master  
configuration port.  
Before the master configuration port can access the configuration  
mode, all ports on the Model 24SII DES must be inactive (i.e. all red  
LEDs must be off) and there can be no print jobs in the buffer. Once  
the master configuration port has accessed the configuration mode,  
the LEDs for Port 1 of Module 1 and the LEDs for the selected module  
will illuminate and will remain illuminated while configuration is  
occurring. All devices connected to the selected module for  
configuration will be unable to communicate with the Model 24SII DES  
while configuration of that module is occurring.  
Before a computer not connected to the master configuration port can  
access configuration mode, the LEDs for its module must be out (i.e.,  
no activity on the module) and there can be no print jobs in the buffer  
for any port on that module. Once the computer has accessed  
configuration mode for its module, the LEDs for that module will  
illuminate. All devices connected to the module will be unable to  
communicate with the Model 24SII DES while configuration for the  
module is occurring.  
NOTE: Parallel computer ports may not be used for configuration, as  
communication is only one-way.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
To access the configuration mode of the Model 24SII DES, use the  
following procedure:  
1.  
Connect a dumb terminal (or a PC running a terminal  
emulation program) to the master configuration port  
(Port 1 of Module 1) or to any serial computer port.  
Configure your terminal's serial parameters to match  
those of the Model 24SII DES. From the factory, all  
serial ports on the Model 24SII DES are factory set at  
9600 baud rate, 8 word size, 1 stop bit, no parity, and  
XON/XOFF disabled.  
If you do not have a dumb terminal or a terminal  
emulation program, BayTech supplies a utility diskette  
which includes software to put an IBM PC or compatible  
into a terminal mode. See Section 4.2 for instructions to  
obtain the software (TERM.EXE) and Section 4.6 for  
instructions to use TERM for configuration.  
2.  
Send from this device to the Model 24SII DES port being  
used for configuration the following control characters:  
ASCII Control-T (14 Hex), ASCII capital C (43 Hex),  
and the desired module number (1 to 6).  
For example, if your terminal is connected to Port 1 of Module  
1 and you wish to configure a port on Module 1, you would  
send the following: <Control-T>C1.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
NOTE: A serial computer connected to a port other than Port 1 of  
Module 1 cannot access configuration mode for its module while the  
master configuration port is configuring a module.  
NOTE: If a computer attempts to configure a feature that is only  
accessible to the master configuration port, Port 1 of Module 1, the  
computer will be sent this message by the Model 24SII DES:  
This Option is accessible via Port 1, Module 1 ONLY.  
Strike any Key to continue  
NOTE: If a computer port other than the master configuration port  
attempts to access configuration mode of a module that it is not  
connected to, the Model 24SII DES will ignore the configuration  
request and create a print job consisting of Control-T, C, and the  
module number.  
CAUTION: If you have a M24SII-V07 installed as Module 1, do not  
configure Port 1 of this module for any baud rate higher than 115,200  
or you will locked out of configuration mode and unable to program  
the various features of the Model 24SII.

A.6 M24SII-V07 MODULE: EIA-422/EIA-232  
PROTOCOL SELECTION AND EXTERNAL  
POWER  
You may configure individual ports on the M24SII-V07 module to  
communicate with either EIA-422 (default) or EIA-232 protocol.  
Protocol selection is accomplished via jumper setting. You may also  
enable external power for individual ports to supply power to the Tran-  
x SP-01 or SP-02 via jumper setting. If you need to reconfigure any of  
the ports on this module type, please use the following instructions.  
1.  
IMPORTANT: If the M24SII-V07 module is installed in the  
Model 24SII chassis, remove power from the Model 24SII by  
positioning the on/off switch to the OFF position and  
unplugging the power cord. Remove the module by  
unscrewing the two straight slot screws securing it to the back  
panel and pulling the module out.  
2.  
Refer to Appendix D.8 and locate the four nine-position jumper  
locations for protocol selection and the four three-position  
jumper locations for external power. The jumper locations are  
marked on the solder side of the connector board for protocol  
selection and external power respectively as JP1 and JP5 for  
Port 1, JP2 and JP6 for Port 2, JP3 and JP7 for Port 3, and  
JP4 and JP8 for Port 4.  
3.  
4.  
Each port is configurable for EIA-422 or EIA-232 protocol by  
installing a six-positon jumper to either the 422 or 232 position  
as marked on the connector board. The center row of holes for  
each port will be occupied by three of the pins on the jumper  
and the row of holes for either EIA-422 or EIA-232 will be  
occupied by the other three pins of this jumper.  
External power is enabled for each port by installing a two-  
position jumper to the +12 position (as marked on the  
connector board) and the center position of the jumper  
location.

Check handshaking. A way to check is  
to force an error condition at the printer  
(i.e. remove paper tray from laser printer  
or turn off-line with power still applied).  
Send print job to printer. If printer LED  
goes off, you can conclude no  
handshaking was done. On serial ports,  
check Model 24SII DES configuration to  
match handshaking (i.e. you must be  
using CTS/DTR or XON/XOFF for both  
Model 24SII DES and printer). Also

Or, Model 24SII DES could be in

available printer which is turned off or is  
not connected. It is highly recommended  
that printers connected to the Model  
24SII DES be plugged in and turned on  
at all times; however, printers need not  
be in the "on-line" mode.

"500H" Series and the Model 24SII DAC Data Acquisition and  
Control units connect between one host computer and multiple  
peripheral devices. These models are often used in industrial  
process-control environments (e.g., for allowing control of multiple  
numerical or assembly-line machines), in exchanging data between  
point-of-sale devices, or for operating a number of laboratory  
instruments or business machines from a central computer. They are  
especially effective in adapting small low-cost personal computers to  
these applications. Each unit features six modes of operation which  
may be easily configured to your application. The 500H series  
models are available with either 5 or 9 ports. The Model 24SII DAC  
unit is expandable from 4 to 24 ports in 4-port modular increments.  
Telplex Models TX104 and TX108 are asynchronous statistical  
multiplexers which multiplex and demultiplex four or eight  
communications channels over a single channel. This single channel  
is typically a telephone line or cable. The TX24 will multiplex and  
demultiplex up to twenty channels. Programmable features include  
serial port parameters (baud rate, word size, etc.), data flow control,  
user-programmable strings to be sent to an external modem, and  
remote diagnostics/configuration capability. These units must be  
purchased in pairs.  
Telplex Model TX104M is an asynchronous statistical multiplexer with  
built-in modem. Four individual communications channels are  
multiplexed into a single dial-up or leased telephone line, cutting  
phone line costs to a minimum. The TX104M features a V.22 bis  
internal modem which provides reliable communication at speeds up  
to 4800 bps. With V.42 bis protocol, the TX104M provides error  
correction and Classes 2-4 data compression. Compatible with most  
computers, printers, or peripherals, the TX104M ensures rapid
