VLINX ESR90x Industrial Ethernet Serial Servers allow connection of RS-
232, RS-422 or RS-485 devices to an Ethernet network. 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 autoselects 10BaseT or 100BaseTX and indicates the type of connection with a
bi-color link light. ESR90x serial servers are built for use in industrial
environments, featuring an IP30, approved slim line DIN rail mountable
case. They operate from a range of AC or DC power supply voltages, support
redundant DC power and feature terminal block power connectors.

Ethernet port of a computer (using an Ethernet crossover cable).
o Web Server allows configuration via the network using a 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 RS232 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 Serial
Server, like any other serial port (legacy, PCI, USB or PCMCIA) on the
computer. Any program running on the computer and using Windowsbased 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
Introduction
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.
Communication Modes
The ESR90x 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.
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.
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.
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.
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.
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.

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.
The power connector is a removable terminal block with four terminals.
From top to bottom the terminals are:

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
Either AC or DC power can be used to
power ESR Serial Servers. Power supply can
voltages range from 9 V to 48 VDC or 8 V
to 24 VAC.
Upgrade Mode
In Upgrade Mode firmware can be uploaded from a PC via its serial port to
the ESR901 serial port or ESR902/904 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
Backup power must be DC voltage and can
be any voltage between 9 VDC and 48 VDC.
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.
Serial Server/Port Operational Modes
Using the ESP Manager, Web Server or Telnet the Serial Server can be put
into Console Mode, Default Mode or Upgrade Mode. The serial ports can be
configured for RS-232, RS-422, RS-485H (half duplex) or RS-485F (full
duplex) operation. The server also can be put into Console Mode by placing
the Run/Console switch in the Console position.

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 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.
Server Properties Configuration
Netmask
The default LAN netmask is configured for a Class C address. The user may
change this. Default is 255.255.255.0
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.
Gateway
The Gateway IP address allows users to access the Serial Server from outside
the LAN.
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.
The IP Address of the Serial Server can be confirmed using the DOS Ping
command.
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.
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.
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
Server Serial Port
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 n will not retain them.
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.

Server Properties Configuration
Flow Control
Server Properties Configuration
Serial Timeout
The Flow Control setting must match the requirements of the serial device
connected.
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 a
connection and communications starts. If communications are ideal for 5
seconds the Serial Server will reset and make itself available for another
client connection.
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.
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.
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.
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 Serial Server 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
Default – When this mode is selected and the server is updated, it will
revert the server to its default configuration.
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.
•
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.
•
Port Status
RS-485H – When this mode is selected and the server updated, the
selected serial port will become a two-wire, half-duplex RS-485 serial
port on the server.
This field indicates whether a serial port is connected via the Serial Server to
a virtual COM port of a device on the network.
•
RS-485F – When this mode is selected and the server updated, the
selected serial port will become a four-wire, full-duplex RS-485 serial
port on the server.
TCP/UDP Port
This sets the port number for connection. The default port number for the
ESR901 serial port is 4000. The default port numbers for serials ports 1, 2, 3
and 4 are 4000, 4001, 4002 and 4003 respectively.
Connection At
When the Connection Mode field is set to Client or Client (no heartbeat),
this field becomes active, allowing the Serial Server (acting as a client) to
connect to the server either on Power up or on Data Arrival (first character
arriving).
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.
Max Connection
Note:
This field allows the user to configure the Serial Server to have up to eight
TCP connections.
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.
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.
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
If Paired Mode is not being used, do not change this setting until the
application has been tested and is communicating properly. Then activate the
address filtering feature.

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.

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 RS422 Receiver and Transmitters.

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.
