ABOUT VESR9XX SERIAL SERVERS
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. Serial ports can be accessed over a LAN/WAN
using Direct IP Mode, Virtual COM Port, or Paired Mode connections.
VESR9xx Serial Servers feature a 10BaseT or 100BaseTX copper
network media. Model VESR922T features an additional copper Ethernet
pass-through port. VESR9xx Serial Serversare 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.

VESR9XX SERIAL SERVER HARDWARE
VESR9xx Serial Servers are enclosed in DIN rail mountable enclosures
and feature LED indicators, power, Ethernet and serial connectors and a
recessed mode switch. VESR9xx Serial Server models are built into
similar enclosures and are DIN rail mountable.
PACKAGE CHECKLIST
VESR9xx Serial Servers ship with the following items included:
•VESR9xx Serial Server Module
•Quick Start Guide
LED INDICATORS (VESR90X)
VESR90x Serial Servers have three LED indicators: Link LED, Ready
LED and two Serial Port LEDs.
LEDs on 1 and 2 Port Serial Servers
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 LED
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.

Model VESR902D features 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 INDICATORS (VESR92X)
Model VESR922T Serial Server has four LED indicators: E1 and E2
LEDs, a Ready LED and two Serial Port LEDs.
LEDs on VESR922T
E1 and E2 LEDs -The E1 and E2 LEDs illuminate (green) if the
Ethernet connection is operating in 100BaseTX mode. The LEDs are off
if the mode is 10BaseT. When the LED is blinking it indicates that there
is data traffic on the Ethernet link.
Ready LED - 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 VESR922T features 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 SWITCH
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.
Top View of the Serial Server
The Mode switch can be used to:
•Initiate a Hardware Reset
•Enter Console Mode
•Reload factory defaults
Note: Refer to Section 3. Serial Server Setup and Connections for
more information on using the Mode switch.
ETHERNET CONNECTOR
VESR9xx models using 10BaseT/100BaseTX (RJ45) connect to a
standard Ethernet network drop using a straight-through RJ45 (male)
Ethernet cable. VESR922T has a second RJ45 receptacle that acts an
Ethernet pass-through connection that functions similar to an Ethernet
switch and allows the connection of other devices to the network.
Ethernet Connector
Note: Refer to Appendix D for connection pin-outs.

SERIAL PORT CONNECTORS
VESR9xx Serial Servers serial port connector configurations (depending
on model):
•Model VESR901 features one serial port and use a DB9M
connector for RS-232 and a five-position removable terminal
block for RS-422 and RS-485 connections.
•Model VESR902D features two serial ports, both using DB9M
connectors for RS-232, RS-422 and RS-485 connections.
•Model VESR922T features two serial ports, both using five-
position removable terminal blocks for RS-232, RS-422 and RS-
485 connections.

SERIAL SERVER SETUP AND CONNECTIONS
This section describes how to set up and connect VESR9xx 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 POWER 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 Watts on model VESR922T.

CONNECTING VESR9XX SERIAL SERVERS TO SERIAL
DEVICES
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 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.
When configured for 2-wire operation the connection supports one
signal pair: Data A (-) and Data B (+) signal channels using 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.

CONNECTING THE VESR901
The VESR901 has one serial connection that supports RS-232, RS-422
and RS-485 (2- and 4-wire). The unit has two connectors: a DB9M
connector and a 5-position terminal block.
If you select RS-232 mode when you configure the serial server, you
must connect the serial device to the serial server via a serial cable. The
VESR901 is a DTE. If the serial device is a DTE, use a null modem
(crossover) cable. If the serial device is a DCE, use a straight-through
cable.
If you select RS-422 mode, RS-485 2-wire mode, or RS-485 4-wire
mode when you configure the serial server, you must connect the serial
device appropriately, via the 5-position terminal block.
Note: Refer to Appendix D for connector pinout information.

CONNECTING THE VESR902D
The VESR902D has two serial connections that support RS-232, RS-422
and RS-485 (2- and 4-wire). The unit has two connectors, both of which
are DB9M connectors. You must connect the serial device to the serial
server via a serial cable. The VESR902D is a DTE. If the serial device is
a DTE, use a null modem (cross-over) cable. If the serial device is a
DCE, use a straight-through cable.
Note: Refer to Appendix D for connector pinout information.

CONNECTING THE VESR922T
The VESR922T has two serial connections that support RS-232, RS-422
and RS-485 (2- and 4-wire). The unit has two connectors, both of which
are 5-position terminal blocks. Make the appropriate connections to the
terminal blocks to match the serial connection mode you select when
configuring the serial server.
Note: Refer to Appendix D for connector pinout information.

CONNECTING VESR9XX SERIAL SERVERS TO A NETWORK
NETWORK CONNECTION (10BASET/100BASETX)
When connecting a serial server equipped with a
10BaseT/100BaseTX network connection (RJ45 connector), a
standard network cable is connected from the serial server to a network
drop. PCs configuring and/or communicating with the serial server are
also connected to the network.
Ethernet Pass-through Port
VESR922T serial server is configured with an additional RJ45 network
port. This port can be used to connect additional Ethernet devices, such
as a local workstation, to the network.
