Introduction
Chapter 1: INTRODUCTION
VLINX Models ESP901 and ESP902 Ethernet Serial Servers provide
Ethernet to Serial connections for RS-232, RS-422 or RS-485 devices.
The ESP901 features a single serial port and the ESP902 features two
serial ports. The serial ports can be accessed over a LAN/WAN using
Direct IP Mode, Virtual COM Port, or Paired Mode connections. The
10/100 Mbps Ethernet connection auto-selects 10BaseT or 100BaseTX
and indicates the type of connection with a bi-color link light.

o VLINX ESP Manager Software for Windows allows
configuration via a network connection or directly from
the Ethernet port of a computer (using an Ethernet
crossover cable).
o Web Server allows configuration via the network using
any web browser.
o Telnet allows configuration via the network by accessing
the setup configuration menu.
o Console Mode allows configuration through an RS-232
serial port in using a VT100 Terminal Emulation program
and an RS-232 crossover cable.
•
Virtual COM Driver Software for Windows - installs virtual
COM ports, viewable in the Windows Device Manager under
Ports (COM & LPT). Virtual COM port provides access to any of
the ports on the ESP901 and ESP902, like any other serial port
(legacy, PCI, USB or PCMCIA) on the computer. Any program
running on the computer and using Windows-based COM ports
can access the serial devices attached to the Serial Server. The
LAN becomes transparent to the serial device and the software
running on the PC.
•
Heart Beat Connection - selectable protocol ensures reliable
communications in Virtual COM Port or Paired Connection
modes. This feature restores the connections if communications are
temporarily lost at either end due to loss of power or the Ethernet
connection.

Introduction
Communication Modes
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.
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.
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.
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.

Introduction
Paired Mode
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 addressfiltering 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.
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.
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.

Making Hardware Connections
Serial Ports
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.

Default Mode
When Default Mode is selected and the server properties are Updated
(Saved) all the configuration settings return to their default values.
Note:
Refer to Chapter 5 for details on Serial Server Configuration settings.
See Chapter 12 for Serial Server default parameters.
Console Mode
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.
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 Chapter 9 for details on Console Mode
Upgrade Mode
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.
Note:
Refer to Appendix A for RS-232 connection pin-outs.

RS-422 Mode
In RS-422 Mode the currently selected serial port is configured as an
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 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.
Note:
Refer to Appendix C for RS-485 connection pin-outs.
RS-485 Receiver Biasing
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).

address, net mask, and gateway to the Serial Server. If a DHCP server
is not available on the network the Serial Server will time out after 10
seconds and the default values will remain. When DHCP is enabled, the
IP Address, Netmask and Gateway fields become inaccessible and
cannot be changed by the user.
Note:
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.
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.
The IP Address of the Serial Server can be confirmed using the DOS
Ping command.
Note:
To use Ping to check for communications:
- Access a DOS window (in XP click Start, then Run)
- At run prompt enter: CMD
- 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

make itself available for another client connection.
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.
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).
•
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 .
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.

Port Status
This field indicates whether a serial port is connected via the Serial
Server to a virtual COM port of a device on the network.
TCP/UDP Port
This sets the port number for connection. The default port number for
the ESP901 is 4000. The default port numbers for the ESP902 are 4000
and 4001 for serial ports 1 and 2 respectively.
In all modes of operation, Direct IP or Virtual COM, the port number
set in the Server Properties menu must match the Virtual COM or
socket software port settings.
Note:
Example: The Virtual COM default setting is TCP/UDP Port 4000. If
the port # property is changed to 4001, the virtual COM port will have
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.
Serial Port Mode
Serial Port Mode allows configuration of the serial server for the
following modes of operation:
•
Console – When this mode is selected and the server is updated, a
PC running a communications program such as HyperTerminal can
communicate with the Serial Server via the Console Mode serial
port (the serial Port on ESP901 or Port 1 on ESP902), displaying
the Server Properties screen and allowing configuration of the
server and its ports.
•
Upgrade – When this mode is selected and the server is updated,
firmware can be uploaded into the Serial Server via the Console
Mode serial port or a virtual COM port mapped to the number of
the Console Mode serial port.
•
Default – When this mode is selected and the server is updated, it
will revert the server to its default configuration.
•
RS-232 – When this mode is selected and the server updated, the
selected serial port will become an RS-232 serial port on the
server.
•
RS-422 – When this mode is selected and the server updated, the
selected serial port will become an RS-422 serial port on the
server.

Installing Virtual COM Port
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 with Flow Control
In the RS-422 mode, TXD lines are outputs and RXD lines are inputs.
Connect the Serial Server TXDB(+) line to the RXDB(+) line of the
serial device, and the Serial Server TXDA(-) to the RXDA(-) of the
serial device.
If Flow Control is set for RTS/CTS, connect the Serial Server
RTSB(+) to CTSB(+) of the serial device and the Serial Server
RTSA(-) line to the CTSA(-) of the serial device. Connect from the
Serial Server CTSB(+) line to the RTSB(+) of the serial device and
from the Serial Server CTSA(-) line to the RTSB(+) line of the serial
device.
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.

Loopback Connections for RS-422
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.
