incorporates an external power supply connection, one coaxial  
connector, a Link Status LED and a Power LED. (The Centronics  
connector on the front of the Print Server plugs directly into a standard  
parallel printer port.)  
• Software upgrades performed by network via FLASH EPROM.  
2.2 Description  
The Patton Model 2126 PeNetTM Print Server supports multi-  
protocol printing in both Novell and TCP/IP LANs, and is fully compliant  
to the ANSI/IEEE 802.2 and 802.3 Standards. Able to recognize up to  
250 servers, the Model 2126 can simultaneously logon to ten of them. If  
the network moves and changes frequently, the Model 2126 can also  
be configured to continuously scan and log on to new servers.  
External Power Jack  
BNC Connection  
Link Status LED  
Power LED  
In case of power loss, the Model 2126 can restore connection to  
servers that are downed. It also supports all the Novell printing and  
print server features. The PeNetTM supports print speeds greater than  
60,000 bytes per second. Configuration is accomplished using a Novell  
compatible utility. (For TCP/IP environments, configuration is  
accomplished via Telnet sessions.) FLASH EPROM allows upgrades to  
be done efficiently through the network.

Follow the steps below to connect the Print Server to the printer and  
network (the order is not critical):  
STOP! If you are connecting the Print Server to a TCP/IP  
network that is not Novell based, go immediately to Section 5.0  
TCP/IP Operation. If you are connecting the Print Server to a  
Novell network, or to a Novell network running TCP/IP, continue  
on to Sections 3.4 and 4.0.  
1. Connect the required network cable (10Base2) to the modular  
connector on the Print Server (The Link Staus LED will not glow  
until power has been applied to the Print Server.)  
3.3 Installing UCONNECT on a Workstation  
2. Plug the power supply adapter into the jack on the rear of the Print  
Server and then into a (surge protected) AC wall outlet.  
UCONNECT is the configuration utility that is supplied with the  
Print Server. UCONNECT allows the Print Server to be installed on a  
Novell network, and will run on any Novell compatible workstation.  
(Note: Both Novell and TCP/IP parameters can be configured using  
UCONNECT. However, you cannot run a TCP/IP session in  
UCONNECT. See Section 5.0 for more information.)  
Note:  
Some printers are able to supply 5 V DC (TTL Spec.) on  
pin 18 of the Centronics connector. If your printer is one  
of these, you may not need the AC power adapter.  
When sufficient power is applied to the Print Server (external or  
interface power), the Power LED will glow and the Print Server will  
boot up. The Link Status LED should also glow, since you have  
presumably accomplished Step 1 already.  
UCONNECT is supplied on a PC-DOS diskette. For your  
convenience, we recommend that you copy the utility (file name  
UCONNECT.EXE) to your workstation hard drive. The transaction  
might look something like this:  
3. Immediately after performing steps 1 & 2, connect the Print Server  
directly to the parallel port of the printer and turn the printer ON (if it  
is not already ON)  
MD C:\UCONNECT  
(insert diskette into drive A)  
COPY A:\*.* C:\UCONNECT  
Approximately 15 - 30 seconds after booting up, the Print Server will  
spool a status page to the Centronics port. If you have connected  
the Print Server to the printer and turned the printer ON within that  
time frame, the status page should print. The status page shows  
the unit’s current operating parameters and proves that a good  
printer connection exists.  
Once the utility program has been copied to the hard drive, type  
UCONNECT at the DOS prompt and press [ENTER] to execute the  
utility.  
What if a status page does not print after 15 - 30 seconds?  
a) If you did not connect to (and turn ON) the printer right away, it is  
possible that the Print Server spooled a status page before the  
printer could respond. Disconnect and reconnect power to the Print  
Server. This will reboot the print server and spool another status  
page.  
(Continued)  
b) Is your printer set up for Postscript? If so, this will interfere with  
the default set-up of the Print Server. The status page may be  
garbled or may not print at all. See Section 4.8 on General  
Troubleshooting.  
c) If your printer has a large buffer, the printing of the status page  
may depend on the timeout setting within your printer. It may take a  
few minutes for a large print buffer to timeout and print.

3.4 Using PCONSOLE  
PCONSOLE is a Novell supplied utility for setting up Print Queues  
and Print Servers. Before it is possible to print using the Print Server  
unit, it will be necessary to use PCONSOLE to inform Novell of the  
presence of a new Print Server and to create/attach print queues to this  
Print Server. You will require Supervisor privileges to create a new  
Print Server and Queue.

4.1 Locating the Print Server on the Network  
Printer Configuration  
This option is used to configure  
printer connected to the PeNetTM  
Print Server. The printer must be  
defined as Parallel LPT1 (parallel  
port 1).  
The Print Server has a unique NIC Address that has been provided  
by Patton Electronics with the approval of the ISO council (this NIC  
Address has been marked on a label on the underside of the unit).  
Before the Print Server can be configured, operated, tested or  
upgraded, it must be located and recognized by the network. Using  
the UCONNECT utility, follow these steps to locate the print server:

[ENTER] key to select a single print server to configure.  
4.2 Configuration within Novell using UCONNECT  
UCONNECT lets you configure the Print Server to work with several  
types of Novell compatible network operating systems. This section will  
guide you through the various configuration options.  
4.2.1 General Configuration  
The first option on the Available Configuration Options screen lets  
you key in general information that will apply to any operating system.  
In most cases you will need to enter information in the General  
Configuration Parameters screen, as well as a second screen that  
applies more specifically to the particular operating system you are  
using.

Password screen. Key in the password “PATTON” and press [ENTER]  
to move to the Available Configuration Options screen.  
Each of the options on the General Configuration Parameters screen  
can be edited using the arrow and [esc] keys to scroll and select.  
1) The Configuration Password may be altered to suit your needs.  
9) The Available Configuration Options screen lets you select several  
pathways of configuration depending upon the operating system your  
network is using. Section 4.3 will give you an overview of the  
configuration options so that you can custom-tailor the Print Server to  
your own requirements.  
2) The Upgrade Password may be altered, but we recommend that  
you leave this password unchanged.  
3) You must change the Postscript Printer field to YES if your  
printer uses Postscript. Otherwise, the printer will not output  
correctly.

4.2.2 Novell Configuration  
2) Once you have selected a print server to configure, you will receive  
the Advanced Novell Configuration screen, where you can point the  
print server to particular file servers and print queues.  
The second option on the Available Configuration Options screen  
lets you enter information to configure the Print Server to work in a  
standard Novell environment. Any of these fields may be edited.  
Warning! Contact your Novell Administrator if you are unfamiliar  
with Novell setup procedures.  
4.2.4 TCP/IP Configuration  
The fourth option on the Available Configuration Options screen lets  
you configure the Print Server to work in a Novell network running  
TCP/IP. Remember: You cannot run a Unix session using  
UCONNECT. See Section 5.0 for TCP/IP operation.  
4.2.3 Advanced Novell Configuration  
The third option on the Available Configuration Options screen is  
“Advanced Novell”. This is UCONNECT’s alternative to the  
PCONSOLE print queue utility. Advanced Novell lets you point a  
particular print server to specific file servers and print queues. This is  
done in two steps:  
4.2.5 Personal Netware Configuration  
1) When you select the Advanced Novell option, you will be prompted to  
supply a print server to configure. Use the arrow and [esc] keys to  
scroll and select the print server you wish to configure. Then press

4.2.6 Reset to Factory Defaults  
2) After you have sent your configuration changes to the print server  
and have seen a timeout at the bottom of your screen, you will then see  
the Reboot screen. Selecting “Yes” on the Reboot screen immediately  
reboots the print server and takes you to the DOS prompt. The  
configuration changes you have entered will now be in effect. Selecting  
“No” on the Reboot screen takes you immediately to the UCONNECT  
Main Menu. Your configuration changes will then not take effect until  
the next time the Print Server is rebooted.  
The sixth option on the Available Configuration Options screen  
resets the Print Server to all Factory Defaults. If you select “Yes” on the  
Reset Available Configuration Options screen, UCONNECT will reset  
the Print Server and return you to the . If you select “no” on the Reset  
screen, UCONNECT will return you immediately to the Available  
Configuration Options screen.

Yes  
No  
Warning! If you select “Yes” you will lose all changes you have  
made in the configuration process.  
Warning! Do NOT remove power while the timeout message is  
displayed! Only after the timeout message disappears is it safe to  
remove power from the Print Server.  
4.2.7 Exit  
4.3 Testing within Novell using UCONNECT  
The seventh option on the Available Configuration Options screen  
exits to the Main Menu. However, you will exit directly to the Main  
Menu only if you have made no changes to the configuration of the unit.  
If you have made changes, you will be sent into the following sequence:  
The UCONNECT utility may be used to test the Print Server in a  
Novell environment. To access the Available Test Options screen,  
perform the operation described in Section 4.2, choosing Test from the  
Main Menu instead of Configure. When the screen appears, pressing  
[ENTER] will cause the Print Server to print a status page, thereby  
testing the setup. Choosing “Exit” will take you back to the DOS  
prompt.  
1) If you select Exit and you have made configuration changes, you will  
next see the Send Changes screen. If you select “No” on this screen,  
you will go immediately to the UCONNECT Main Menu and your  
changes will not be saved. If you select “Yes”, you will receive a  
timeout at the bottom of your screen while UCONNECT sends your  
configuration changes to the Print Server. (Note: the changes you  
entered will not take effect until the Print Server is rebooted.)

4.4 Printing within Novell  
It will be of great benefit to users who are not familiar with the Novell  
printing environment to obtain the Novell flip-guide entitled “Novell  
Quick Access Guide” before continuing with this section. Read the  
chapter entitled “PRINTING” to gain a clearer understanding of the  
Novell printing system. More information is available from Novell’s  
Concepts and Print Server manuals.  
The PeNetTM Print Server interface fully supports all common Novell  
print commands including CAPTURE, NPRINT and PCONSOLE.  
4.6 Troubleshooting within Novell  
This section describes the options available for diagnosing possible  
problems that may occur with the PeNetTM Print Server unit.  
e.g. NPRINT testfile.doc PS=PESERV Queue=TEST  
The Novell set up utility, UCONNECT can be used to force print a  
Status Page to the connected printer. Select Force Status Page from  
the main menus within UCONNECT.  
This command prints a document called ‘testfile.doc’ to the print  
queue called TEST which is serviced by a Print Server called PESERV.  
General  
4.5 Upgrading within Novell  
No Power LED  
The PeNetTM Print Server is equipped with 128k Bytes of FLASH  
EPROM which is used to store the operating code and also the units  
configuration data. If it is necessary to upgrade the units operating  
system (for example if support for new protocols is added) this may be  
easily achieved by transmitting the new operating system to the unit  
over the network. Once transmission is complete, this new code will be  
permanently stored in the units FLASH memory.  
1) Check that external power supply adapter is correct type and is  
functioning correctly.  
2) Ensure DC connector to the Print Server is seated correctly.  
3) If you are relying only upon interface power on pin 18 of the  
Centronics interface, be sure the output is 5 V DC (TTL Spec.).  
Upgrading under Novell is achieved by selecting the UPGRADE  
option from the UCONNECT main menu. Ensure that the units new  
operating system (supplied on a single 3.5 inch diskette containing a  
single file called IMAGEnnn.BIN ) has been copied to the same  
directory that contains UCONNECT.EXE.  
Status Page Not Printed  
1) The status page prints only within 30 seconds of power-up or when  
forced by software (see Test Section 4.3)  
Enter the NIC and Network address of the unit to be upgraded and  
then enter the UPGRADE PASSWORD when prompted (rather than the  
CONFIGURATION PASSWORD with does not permit FLASH  
2) The power-on status page option may be disabled (see  
General Configuration Section 4.2.1)  
upgrades). Once communication to the unit in question has been  
achieved, a window will appear on the screen displaying the progress of  
the file transfer from UCONNECT to the Print Server (see following  
page). Once this window disappears, the FLASH upgrade is complete.  
3) The Postscript printer option may be set incorrectly for your printer  
(see General Configuration Section 4.2.1)  
4) Your printer may have a large internal buffer, in which case the  
status page may have spooled to your printer but is waiting for a  
timeout or command in order to print. (Check your Printer manual.)

5.0 TCP/IP OPERATION  
Novell Specific  
This section tells how to use the Print Server with a TCP/IP  
network. Functions described include locating the Print Server on the  
network, configuration, initialization, testing, printing, and FLASH  
EPROM upgrading.  
UCONNECT Can’t Communicate with Print Server  
1) Check the correct Network Number and NIC Address have been  
entered  
5.1 Locating the Print Server on the TCP/IP Network  
2) Ensure PeNetTM Print Server is functioning correctly (check the  
power LED and status page production)  
When used in the TCP/IP environment, the Print Server has one  
assigned Internet Address and one printer port.  
5.1.1 Assigning the Internet Address  
Status Page Shows No Novell Server or Queue Details  
If it is not possible to use the UCONNECT utility to configure the  
units Internet Address, then the following method should be followed:  
1) If Server shows, but no Queue details, then no Print Queues have  
been assigned (See PCONSOLE Section 3.4 or consult your Novell  
Administrator)  
1. Create an entry in the ARP table using the Unix command :  
arp -S [ether] IPaddress NICaddress where...  
IPaddress is the required Internet Address  
2) See section on “PeNetTM Print Server Unable To Login” (below)  
Print Server Is Unable To LOGIN To Novell Servers  
NICaddress is the units NIC address  
1) Check that ‘Allow Unencrypted Passwords’ has been set to ON  
2. Use PING to send this new IP address to the NIC address of the  
Print Server:  
2) Ensure that the units Name and Password are as allocated in  
PCONSOLE  
PING xx.xx.xx.xx where xx.xx.xx.xx is the IP address above  
3) Check that there is a connection available for PeNetTM Print Server  
(use Monitor on the Server Console)  
NOTE: This method will only work if the units Internet Address is  
currently set to 0.0.0.0 and PING will only affect the unit with  
the NIC address entered in the ARP table.  
4) If Selective Login is enabled, ensure correct File Server name(s)  
have been entered  
Some versions of Unix will require the ‘ether’ command to be  
entered as shown  
5) Check that Novell Mode is not disabled

5.1.2 Using PING to Verify Network Communications  
5.2.1 Telnet Configuration Commands  
PING is the standard method used on TCP/IP networks to verify that  
communication is possible to and from a given Internet address  
(NOTE: not all TPC/IP networks have the PING utility. Its use with the  
Print Server is optional). The Print Server will correctly respond to  
PING requests and hence a typical method of quickly establishing if  
communications are possible with the Print Server would be:  
The following commands may be entered from the command  
prompt:  
GENERAL  
NOVELL  
Displays the current General parameters  
Displays the current Novell parameters  
Hint: Deleting the Novell login name will turn off Novell server  
search and speed up TCP/IP operations. This step is highly  
recommended.  
PING xx.xx.xx.xx where xx.xx.xx.xx. is the unit’s Internet address  
PING will then report to the operator if communication was  
achieved. If problems exist communicating with the Print Server,  
carefully check that the Internet Address allocated to the unit is a valid  
address for the network in question. Consult the network supervisor if  
problems persist with PING.  
TCPIP  
Displays the current TCP/IP parameters  
PERSONAL  
Displays the current Personal Novell  
parameters  
HELP  
Displays a help screen  
5.2 Configuration within TCP/IP  
SET [parameter] = [value] Sets parameter to given value  
Once the unit’s Internet Address has been set correctly and PING  
has proven that network communications are possible to the unit, now is  
the time to use Telnet to further configure the unit if required. Here is a  
typical transaction used to connect to the Print Server via Telnet:  
EXIT  
Exits from Telnet

Once connection to the Print Server has been achieved using the  
Telnet Protocol, it is then simply necessary to enter the command,  
PESETUP, to enter the configuration utility. The Print Server will then  
prompt the user to enter a password (default is Patton) and, once the  
entered password has been verified, a command prompt will appear.

For example, to set the Power Up Status Page option to NO, the  
following would be required:  
Setup the Print Server as for normal TCP/IP operation regarding  
Internet Address etc. and then use SMIT to add a host with the PeNetTM  
Print Server’s Host Name. Add a remote queue and specify  
Destination Host (as above) and Queue, on Remote Printer=Pport1 (or  
other PeNetTM Print Server port). Set the Remote Device To Add to the  
Printer Name for this printer.  
SET PU = NO  
Technical Note: The Print Server unit responds to Telnet Data  
in accordance with RFC 854 on the standard Telnet Port, 23  
(decimal).  
To print, use the following command: LPR -P printer name file.txt  
5.3.3 Printing Using FTP  
5.3 Printing within TCP/IP  
It is also possible to print files to the Print Server using FTP (File  
Transfer Protocol). Typically this would be achieved by instigating an  
FTP session, as the sequence of commands below shows:  
There are two main methods of printing documents to the Print  
Server using the TCP/IP protocol:  
PRR  
FTP  
Berkeley remote LPR (LPD daemon)  
File Transfer Protocol  
ftp hostname where hostname is the Print Server to connect to  
put filename  
quit  
NOTE: Printing from ‘LP’ or ‘LPR’ on Unix V systems, is only  
possible if an application program is available to re-route  
print data to the LPR socket.  
5.3.4 Printing From SCO UNIX  
SCO Unix no longer supports remote LPR so the FTP method of  
printing will need to be used. A script file can be created to automate  
this process as shown below:  
5.3.1 Printing using LPR  
The typical command line for sending a print via remote LPR to the  
PeNetTM Print Server would be:  
TMPFILE=/tmp/ftpprint.$$  
printer=laserprt $(0)  
LP -d printdef file.txt where printdef is the printer name  
defined in a printcap file, with  
/usr/spool/lp/model/standard “$@”>$TMPFILE  
ftp -n $printer <<END  
binary  
:rm=Host Name and :rp=Port Name  
put $TMPFILE  
quit  
rm $TMPFILE  
exit  
The LPQ and LPSTAT commands are supported by Print Server by  
returning “No Entries”  
5.3.2 Printing From IBM AIX  
The script intercepts the print command and redirects the output to  
a temporary file. FTP then sends this file to the host before deleting it  
and exiting from the script file.  
Printing from AIX using LPR is possible. The necessary setup is  
performed with a utility called SMIT.  
Technical Note: The Print Server unit supports the LPR protocol  
as defined in RFC 1179 and FTP as defined in RFC 959. The unit  
responds to LPR data sent to socket 515 and FTP data sent to  
socket 20.

5.4 Upgrading withinTCP/IP  
5.5 Troubleshooting within TCP/IP  
To use the FTP based method of FLASH upgrade, it is firstly necessary  
to establish an FTP connection to the Print Server in the same way as  
that used when printing to the unit via FTP. Typically this will be  
achieved as follows:  
The following hints should help you if trouble arises when using the  
Print Server. If you experience additional problems, contact Patton  
Technical Support M-F, 8:30 - 5:00 PM EST at (301) 975-1007.  
General  
FTP xx.xx.xx.xx where  
xx.xx.xx.xx is the unit’s Internet Address  
No Power LED  
Once connection is achieved in this way, the Print Server will  
respond with a prompt requesting the USER NAME to be supplied.  
When printing to the unit, this field may be ignored but when preparing  
to perform a FLASH upgrade, it is the response to this field that  
indicates an upgrade is being performed. To continue with the upgrade  
procedure, the user must enter:  
1) Check that external power supply adapter is correct type and is  
functioning correctly.  
2) Ensure DC connector to the Print Server is seated correctly.  
3) If you are relying only upon interface power on pin 18 of the  
Centronics interface, be sure the output is 5 V DC (TTL Spec.).  
pattonflashupdate  
followed by carriage return. It is now necessary to transmit the new  
operating system to the Print Server. The units new operating system  
will be supplied on a single 3.5 inch diskette which will contain a single  
file called IMAGEnnn.BIN (where nnn is the version number of the  
upgrade). This file is typically transmitted to the Print Server using the  
PUT command as shown below:  
Status Page Not Printed  
1) The status page prints only within 30 seconds of power-up or when  
forced by software (see Section 5.2.1)  
2) The power-on status page option may be disabled (see Section  
5.2.1)  
PUT IMAGE.BIN  
Assuming that the file transfer was completed correctly, the Print Server  
will respond to the end of transfer with the message:  
3) The Postscript printer option may be set incorrectly for your printer  
(see Section 5.2.1)  
FILE TRANSFER COMPLETE - Upgrade continues when FTP is quit  
4) Your printer may have a large internal buffer, in which case the  
status page may have spooled to your printer but is waiting for a  
timeout or command in order to print. (Check your Printer manual.)  
Quitting FTP will now cause the FLASH upgrade to occur, and after a  
few seconds, the unit will reboot and begin operating using the newly  
downloaded operating system.
