Introduction
Introduction
Communication Modes
Paired Mode
The ESP901 and ESP902 Serial Servers enable communication with
serial devices over a LAN or WAN. Serial devices no longer are
limited to a physical connection to the PC COM port. They can be
installed anywhere on the LAN using TCP/IP or UDP/IP
communications. This allows traditional Windows PC software access
to serial devices anywhere on the LAN/WAN network.
Paired Mode is also called serial tunneling. In this mode any two serial
devices that can communicate with a serial link will be able to
communicate using two Serial Servers and the LAN.
Two Serial Servers are connected to a network, one configured as a
TCP or UDP client and the other as a TCP/UDP server. When setting
up the server the remote IP address section must contain the address of
the client. This will allow the client’s IP address to pass the IP address-
filtering feature of the server. Conversely, the Remote IP address of the
client must contain the server’s IP address. Both communication port
numbers must be the same.
Direct IP Mode
Direct IP connections allow applications using TCP/IP or UDP/IP
socket programs to communicate with the asynchronous serial ports on
the Serial Server. In this type of application the Serial Server is
configured as a TCP or UDP server. The socket program running on the
PC establishes a communication connection with the Serial Server.
The data is sent directly to and from the serial port on the server. When
using UDP protocol the server can be configured to broadcast data to
and receive data from multiple IP addresses.
Heart Beat
The Heart Beat protocol connection provides
a
reliable
communications connection in Virtual COM Port Mode or with Paired
Connection Mode. This feature restores the connection if
communications are temporarily lost at either end due to loss of power
or Ethernet connection.
Virtual COM Mode
Install Virtual COM Mode allows the user to add a driver, to provide a
virtual COM port on the computer. The new COM port shows up in the
Device Manager. Windows programs using standard Windows API
calls are able to interface to virtual COM ports. When a program on the
PC opens the new COM port, it communicates with the remote serial
device connected to one of the ports on the Serial Server.
Without this feature a device that loses a connection and stops
communicating would not be able to reconnect without human
intervention. A TCP data connection can be lost when there is a power
failure or temporary loss of an Ethernet connection on either the client
or server. If a loss occurs the Heart Beat feature will try to reconnect
the TCP data connection every five seconds until communications is
established again. The Heart Beat feature is available for use in Virtual
COM Port Mode and Paired Connection Mode. This is not available
when using a UDP application.
After connection, the LAN is transparent to the program and serial
device. Applications are able to work just as if the serial device is
connected directly to a physical COM port on the computer. The virtual
COM port software converts the application’s data into IP packets,
sends it across the network to the Serial Server, which converts the IP
packet back to serial data and sends the data out a serial port located on
the Serial Server.
To use this mode, the Serial Server must be set to either TCP/server or
UDP/server with a designated communication port number. The virtual
COM driver is the TCP or UDP client.

DIP Switches
Serial Ports
A triple DIP (dual inline package) switch allows the Serial Server to
be placed into Console Mode. When all three switches are moved into
the ON position the Serial Server enters Console Mode, allowing
configuration of the Serial Server (using an RS-232 connection
through the serial port on the ESP901 or Serial Port 1 on the ESP902)
from a PC running a terminal program such as HyperTerminal. When
the Serial Server enters Console Mode the Console Mode screen will
appear in the HyperTerminal program window. The serial port settings
must be 8-N-1 at 9600 baud.
The ESP901 has one serial port. The port can be configured as a
Console Mode connection or as an RS-232, RS-422 or RS-485
interface to the Serial Server (if any of the DIP switches are in the
OFF position) using the ESP Manager software, via Telnet, or using
the Web Server.
The ESP902 has two serial ports. Port 1 operates the same as the
ESP901 serial port. Port 2 on the ESP902 is an RS-232 only interface.
The RS-232 interfaces are configured as DTEs. The connectors for all
ports are DB-9M.

(Saved) all the configuration settings return to their default values.
RS-422 interface supporting four RS-422 signal channels with full
duplex operation for Receive, Transmit, RTS (Request To Send) and
CTS (Clear To Send). The data lines are differential pairs (A & B) in
which the B line is positive relative to the A line in the idle (mark)
state. Ground provides a common mode reference. To use handshaking,
Flow Control must be set to RTS/CTS during configuration.
Note:
Refer to Chapter 5 for details on Serial Server Configuration settings.
See Chapter 12 for Serial Server default parameters.
Console Mode
Note:
In Console Mode the Configuration Menu can be accessed from a PC
by connecting its RS-232 serial port to the ESP901 serial port or
ESP902 Serial Port 1. Since the computer is a DTE device, and the
serial ports are configured as DTEs (with DB-9M connectors), a null
modem crossover cable must be used.
Refer to Appendix B RS-422 connection pin-outs.
RS-485 Mode
In RS-485 Mode the currently selected port is configured as an RS-485
interface supporting transmit (TX) and receive (RX) signal channels
using 2-wire, half-duplex operation. The data lines are differential with
the Data B line positive relative to Data A in the idle (mark) state.
Ground provides a common mode reference.
In Console Mode the default serial port settings are: 9600 baud, 8 data
bits, No parity, and 1 stop bit. From Windows, HyperTerminal with
VT100 terminal emulation can be used for Console Mode
configuration.
Note:
Refer to Appendix C for RS-485 connection pin-outs.
Note:
Refer to Chapter 9 for details on Console Mode
RS-485 Receiver Biasing
Upgrade Mode
RS-485 Receiver Biasing can be implemented from the Serial Server
if the network does not supply it. Remove the two side-cover screws of
the Serial Server, slide the cover off and re-position the bias jumpers
(shown open in the figure below) to enable biasing (shorting).
In Upgrade Mode firmware can be uploaded from a PC via its serial
port to the ESP901 serial port or ESP902 Serial Port 1. Upgrading also
can be accomplished via the network connection, using the ESP
Manager software and a virtual COM port.
Note:
Refer to Chapter 8 for details on Upgrade Mode
RS-232 Mode
In RS-232 Mode the currently selected serial port is configured as an
RS-232 interface supporting eight RS-232 signal lines plus Signal
Ground and is configured as a DTE, like a computer. Signals are single
ended and referenced to Ground. To use handshaking, Flow Control
must be set to RTS/CTS during Configuration.

Description of the Server Properties
Chapter 5: CONFIGURING THE
SERIAL SERVER PROPERTIES
The VLINX Serial Server can be configured using any of four different
user interfaces: the ESP Manager software, Console Mode, Telnet or
the Web Server. The Server Properties described in this chapter can
be changed from any of these user interfaces.
Figure 30.
ESP Manager Server Properties Window
Server Name
This field displays the name that has been assigned to the Serial
Server. A new Server Name of up to 16 characters can be entered. If
more than one Serial Server is connected on the LAN it is
recommended that a new name be assigned to each. When the ESP
Manager finds a Serial Server on the LAN it displays the server name
and IP Address allowing the user to distinguish between Serial
Servers.
Serial Number
Each Serial Server has a unique serial number. This is fixed and
cannot be changed.
Password
Entering a password activates a security feature on the Serial Server.
Once a password is entered it will be required to access the menu and
make changes.
DHCP
DHCP servers are a part of numerous LAN management systems. The
DHCP field provides two choices: Disable and Enable. Disable is the
normal, or default, setting. When enabled, the Serial Server will send a
DHCP request to the DHCP server, which will assign a dynamic IP

may change this. Default is 255.255.255.0
Gateway
Note:
The Gateway IP address allows users to access the Serial Server from
outside the LAN.
A dynamic address assigned by the DHCP server may change if the
server loses the Ethernet connection or power is removed. The host
(client) communication software requests a connection to the specific
IP address of the serial server. If the DHCP reassigns a different IP
address the software will not be able to communicate with the
hardware. Therefore, using a static IP address is recommended.
MAC Address
The MAC address is fixed and cannot be changed. It is assigned in the
factory. Every Ethernet device manufactured has it own unique MAC
address.
IP Address
Software or hardware attempting to access the Serial Server via the
network must know the IP Address of the server. A static IP address is
retained and remains the same each time the server is powered up or
starts/restarts. The default IP address of the Serial Server is printed on
a label on its bottom cover. Entering an appropriate address in the IP
Address field and updating the server will change the server’s IP
address. The network administrator can assign/establish the static
address or group of addresses to be used.
Version & Date
The currently loaded version of the firmware, and when it was released,
is shown here.
Link Status
Link status automatically displays the type of Ethernet connection. It
will either display 10BaseT or 100BaseTX in full duplex or half
duplex. This will depend on the LAN, switches, hubs used in the LAN
topology.
The IP Address of the Serial Server can be confirmed using the DOS
Ping command.
Server Serial Port
Note:
To use Ping to check for communications:
- Access a DOS window (in XP click Start, then Run)
- At run prompt enter: CMD
This field indicates the number of the port for with Serial Server
properties are currently being displayed. Changing the number in this
field will cause all the other fields to display the properties for the
specified port. Note, however, that before changing ports, any changes
to properties must be Updated (Saved) or the Serial Server will not
retain them.
- In the DOS window enter: Ping xxx.xxx.xxx.xxx (IP address for the
server to be confirmed)
- The command will return the Ping results indicating 4 replies
Baud Rate
The serial port baud rate on the Serial Server must match the serial
baud rate of the connected device unless using Virtual COM Mode. In
Virtual COM Mode the software program will establish serial settings.
Data/Parity/Stop
Set this to match the data format used by the serial device connected
when Virtual COM Mode is not being used.

communications are ideal for 5 seconds the Serial Server will reset and
make itself available for another client connection.
Flow Control
The Flow Control setting must match the requirements of the serial
device connected.
TCP Alive Timeout
The Serial Server monitors TCP activity. If TCP activity stops for the
length of time specified in this field the connection will be closed. This
field can be set to any value between 0 and 255 minutes. If zero, or no
value, is entered into this field the server will not disconnect.
Note:
Select None when setting the port as RS-485 or 4-wire RS-422.
TCP/UDP Protocol
Select TCP (Transmission Control Protocol) or UDP (User Datagram
Protocol) protocol. If the application does not require a UDP
connection, select TCP. TCP guarantees reliable communication with
error checking whereas UDP provides faster transmission.
Connection Mode
The Connection Mode field has three options: Server, Client and
Client (no heartbeat). When Client or Client (no heartbeat) is
selected the Connection at field automatically becomes active
(allowing the user to select Power up or Data Arrival).
UDP Mode
When UDP mode is chosen the Serial timeout, TCP alive timeout,
Connection mode, Connection at, Max connection and
Remote IP address fields are replaced with the following
four fields: Destination IP address range, Port number and
Source IP address range. In this mode the server can be
configured to broadcast data to and receive data from multiple
IP addresses. Four IP address range fields are provided.
•
•
•
When using the Virtual COM Port feature, select Server.
When using a TCP or UDP Socket program, select Server.
When using Paired Mode communication between two serial
servers set up one as a Client and the other as a Server.
•
When connecting to a server that does not support Heartbeat,
select Client (no Heartbeat).
Delimiter HEX 1 and Delimiter HEX 2
These fields allow the user to enter two ASCII characters (in hex
format) that delimit the beginning and end of a message. When a
message with both these delimiters is received at the serial port, the
data contained in the serial buffer is placed in an Ethernet packet and
sent out the Ethernet port. If only Delimiter 1 is set (Delimiter 2 is zero
or blank), upon receiving Delimiter 1 the ESP901/902 will put all the
data in the serial buffer in an Ethernet packet and send it out the
Ethernet port. If serial data greater than 1 kilobyte is received it will
automatically be placed in an Ethernet packet and sent out the Ethernet
port .
Figure 32. The Server UDP Configuration Screen
Force Transmit
This field allows the user to set a maximum time limit between
transmissions of data. The value set in this field multiplied by 100 ms
determines the Force Transmit time. When the elapsed time reaches the
time configured in this field, the TCP/IP protocol will pack the data
currently in the serial buffer into a packet and send it out the Ethernet
port.
Serial Timeout
Default for the Timeout property is 0, or no timeout. Setting Timeout
to any value between 1 and 65535 seconds activates it. If Timeout is
set to 5 seconds and the Serial Server is configured as a Server, the
Client makes

to be changed to 4001. The hardware settings can be changed from
the ESP Manager or Console Configuration Menu. The Virtual COM
port setting also can be changed within the Device Manager of the
computer on which it is installed.
Remote IP Address
This is a security feature activated by entering the IP address of the
desired client. The Serial Server will only communicate with the listed
IP address and all other requests for connection will be filtered out. The
Serial Server must be set up as a TCP or UDP Server to use this
feature. The default setting is 255.255.255.255.

Installing Virtual COM Port
Installing Virtual COM Port
The program searches the LAN for all available Serial Servers. When
complete, the Found Server window appears and displays a list of the
servers that were found.
Chapter 6: INSTALLING VIRTUAL
COM PORTS
The Virtual COM Port feature allows Windows platform software, using
standard API calls, to be used in an Ethernet application.
The Install Virtual COM Port software adds a Serial Server (COM#) port to the
computer. This shows up in the Device Manager. The COM number can be
selected from a list of available numbers. For example, in a computer already
having a COM1 and COM2, COM3 to COM 254 are available for the Serial
Server. It is recommended that COM Port 5 or higher be selected. The virtual
COM port looks like a standard COM port to most Windows based applications
which allows the software to open a connection with the serial port located
anywhere on the LAN/WAN. When using the virtual COM port the Serial
Server is configured as a TCP or UDP Server.

RS-422 Connections in a DB-9 Connector
If connecting to Receive Only RS-422 devices, connect from the
Serial Server TXDB(+) and TXDA(-) lines to the receive pairs on all
serial devices.
Ground is signal ground and provides a common mode reference for
the RS-422 Receiver and Transmitters.
Note:
The RS-422 mode can be used for full duplex 4-wire RS-485 operation
provided that the serial server is acting as a sole master connecting to
all the slave devices, and all slave devices share the Receive signal
lines to the master. Set Flow Control for none, and omit connections to
RTS/CTS line pairs.

The RS-485 Connections are half duplex, either Receive or Transmit,
so another half duplex device must be used to check operation.

DB-9 Pin-out in RS-485 Mode
Note:
Some RS-485 devices are marked opposite the RS-485 standard,
which defines the Data B line as positive relative to Data A during a
Mark state before enabling the transmitter, and after transmitting
before tri-stating. If an RS-485 device does not respond, try swapping
the Data B and Data A lines.
Figure 71. 2-wire RS-485 Connection
To connect 4-Wire RS-485 devices, the RS-422 Mode can be used
provided the Serial Server will be connected as a master in a single
master system. If using multiple masters, the Serial Server cannot be
used, as it does not tri-state the transmitter in RS-422 mode.
