ABOUT VE SR9XX SERIA L S ERVERS
VESR9xx Serial Servers connect serial devices (RS-232, RS-422 or RS-485) to Ethernet
networks, allowing the serial device to become a node on the network. The serial
ports can be accessed over a LAN/WAN using Direct IP Mode, Virtual COM Port, or
Paired Mode connections. VESR9xx Serial Servers feature 10BaseT or 100BaseTX
copper network media and several fiber optic media options, depending on the
model. VESR92x serial servers feature an additional copper Ethernet pass-through
port. VESR9xx 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 DC
power supply voltages and feature pluggable terminal block power connectors.
VESR9 XX SERIAL S ERV ER MODEL NUM BER ING
VESR9xx Serial Server are a growing family of products. Models are available with
one or two serial connections and one or two Ethernet connections. Network
connection options include 10BaseT/100BaseTX copper or several different fiber
optic options (on models with a pass-through port, the pass-through port is copper).

Hardware
LINK LED
The Link LED illuminates (green) if the Ethernet connection is operating in 100BaseTX
mode. The LED is off if the mode is 10BaseT. When the LED is blinking it indicates
that there is data traffic on the Ethernet link.
READY LE D
The Ready LED (green) blinks once per second if the system is operating correctly. If
the LED is off, it indicates the system is not operating correctly.
SERIAL PORT LEDS
VESR901-x serial servers feature one serial port. VESR902D,and VESR902T-x serial
servers feature two serial ports. Each serial port has an associated LED. Serial Port
LEDs blink (green) when data is being transmitted or received on the serial port.
When the LED is On it indicates the serial port is open.
LED INDI CATORS ( VES R92X)
VESR92x Serial Servers have four LED indicators: E1 and E2 LEDs, a Ready LED and
two Serial Port LEDs.

the LED is off, it indicates the system is not operating correctly.
Serial Port LEDs
VESR921-x serial servers feature one serial port. VESR922x, serial servers feature two
serial ports. Each serial port has an associated LED. Serial Port LEDs blink (green)
when data is being transmitted or received on the serial port. When the LED is On it
indicates the serial port is open.
MODE SWI TCH
A recessed momentary reset switch is located on the top of the enclosure. To
activate the switch, insert a small plastic tool through the hole in the enclosure and
press lightly.

ETHER NET CONNECT OR
Serial server models using 10BaseT/100BaseTX network connections use an RJ45
receptacle. The serial server is connected to a standard Ethernet network drop using
a straight-through RJ45 (male) Ethernet cable. VESR92x models feature a second
RJ45 receptacle which acts an Ethernet pass-through connection. This connection
functions similar to an Ethernet switch and allows the connection of other devices to
the network.

Note: Refer to Appendix D for connection pin-outs.
FIBER OP TIC CONNECTORS
Serial server models using fiber Optic network connections use either SC or ST
connectors, depending on the specific model.

Hardware
VESRxx Serial Servers use three serial port connector configurations, depending on
the model:
VESR901-x serial servers feature one serial port and use a DB-9M connector for RS232 and a five-position removable terminal block for RS-422 and RS-485 connections.
VESR902D-x serial servers feature two serial ports, both using DB-9M connectors for
RS-232, RS-422 and RS-485 connections.
VESR902T-x serial servers feature two serial ports, both using five-position
removable terminal blocks for RS-232, RS-422 and RS-485 connections.

Setup and Connections
SE RIA L SERVER SETUP AND CONN ECTIONS
This section describes how to setup and connect VESRxx Serial Servers.
Note: In this section devices to be connected to the serial server’s serial connection are
simply referred to as the “serial device”.
CONNECTING THE P OWE R SUPPLY
Connect a DC power supply to the power terminals on the top of the serial server.
Polarity of the wires is indicated on the label on the side of the serial server.
Acceptable voltages are between 10 VDC and 48 VDC. The power supply must be
capable of supplying 4 Watts for VESR90x models and 6.0 Watts for VESR92x models.
CONNECTING VESR9XX SER IAL SERVERS TO SE RIA L D EVICES
VESR9xx Serial Servers can be configured to connect to serial devices using RS-232,
RS-422, RS-485 2-wire and RS-485 4-wire.
RS-232 connections support eight signal lines plus Signal Ground. Signals are single
ended and referenced to Ground. Default communications parameters are 9600, 8,
N, 1 and no flow control implemented.
RS-422 connections support two signal pairs: TDA (-), TDB (+), RDA (-), RDB (+) and
GND. 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.
RS-485 connections support 2-wire or 4-wire operation.
When configured for 4-wire operation the connection supports two signal pairs: TDA
(-), TDB (+), RDA (-), RDB (+) and GND. This makes full-duplex operation possible. The
