About VESR4x4 Serial Servers
VESR4x4 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. VESR4x4 Serial Servers
feature 10BaseT or 100BaseTX copper network media and several fiber optic
media options, depending on the model. Many models also feature an
additional copper Ethernet pass-through port. VESR4x4 Serial Servers are built
for use in industrial environments and feature heavy duty metal enclosures
that are panel and DIN rail mountable. The product operates from a range of
DC power supply voltages and features pluggable terminal block power
connectors as well as a locking barrel connector that facilitates redundant
power sources.

Power LED
The Power LED illuminates when 10 to 58 VDC power is applied to either
power connector.
Ready LED
The Ready LED (green) illuminates continuously while the unit is initializing. It
flashes once per second when the system is operating correctly. If the LED is
not flashing, it indicates that something is wrong (e.g. another device on the
network at the same IP address).
Ethernet Speed LEDs (1 & 2)
The Ethernet Speed LED illuminates (green) if the Ethernet connection is
operating at 100Mbit/sec. The LED is off if the connection is operating at
10Mbit/sec.
Ethernet Link LEDs (1 & 2)
The Ethernet Link LED illuminates when a connection has been made. It
flashes when there is data traffic on the Ethernet link.
Serial Port LEDs (P1, P2, P3 & P4)
Each serial port has an associated LED. Serial Port LEDs flash (green) when
data is being transmitted or received on the serial ports. When the LED is
illuminated it indicates the serial port is open.

Note: LEDs on the serial server are also used to indicate various Reset modes, as described in the
following section.
Reset Switch
A recessed momentary Reset switch is located on the side of the enclosure.
To activate the switch, insert a small plastic tool through the hole in the
enclosure and press lightly.
Figure 4. Side View of the Serial Server
The Reset switch is used to:
Initiate a Hardware Reset
Enter Console Mode
Reload factory defaults
Using the Reset Switch to Initiate a Hardware Reset
Hold the Reset switch in for 0 to 2 seconds. The P1 LED illuminates while the
switch is being held in. Release the switch in less than two seconds or the
serial server will enter Console Mode.
Using the Reset Switch to Enter Console Mode
Hold the Reset switch for between two and ten seconds. The P1 LED
illuminates for the first two seconds and the P1 LED goes out; then the P2 LED
illuminates until the Reset switch is released. Release the switch in less than
10 seconds or the serial server will reset to factory default settings. The serial
server will re-boot and enter Console Mode. LED P1 will be on while the unit is
in Console Mode.
Using the Reset Switch to exit Console Mode
Press the Reset switch for less than two seconds, or remove power from the
serial server, wait a few seconds, and turn the power on again. The LEDs go
back to their normal states when the device resumes normal operation.

Using the Reset Switch to Reload Factory Default Settings
Hold the Reset switch for more than ten seconds. The P1 LED illuminates for
the first two seconds; then the P2 LED illuminates. After 10 seconds the P1
and P2 LEDs will illuminate. When the switch is released, both the P1 and P2
LEDs will go out. The Ready LED will flash quickly while the serial server re-
initializes to factory default settings, and then the server will re-boot.
Ethernet Connector
Serial server models equipped with 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. Models
with a second RJ45 receptacle act as an Ethernet switch enabling the
connection of other devices to the network.
Figure 5. Ethernet Connectors
Note: Refer to Appendix D for connector pinouts.
Fiber Optic Connectors
Serial server models equipped with fiber-optic network connections use either
SC or ST connectors, depending on the specific model.
Figure 6. SC and ST Fiber Optic Cable Connectors

Serial Port Connectors
VESR4x4 Serial Servers feature two serial port connector configurations,
depending on the model:
VESR4x4D-x serial servers feature four serial ports, all of which use DB-
9M connectors for RS-232, RS-422 and RS-485 connections.
VESR4x4T-x serial servers feature four serial ports, all of which use five-
position removable terminal blocks for RS-232, RS-422 and RS-485
connections.

Figure 8. Five-Position Pluggable Terminal Blocks
Note: Refer to Appendix D for connector pinouts.
Power Connector
VESR4x4 serial servers provide two power connectors. One is a three position
removable terminal block with +, - and chassis ground connections. The other
is a locking barrel jack connector.

Mounting Hardware
VESR4x4 Serial Servers can be DIN rail or panel mounted. The necessary
hardware is included in the accessory kit, which also includes the screws for
attaching the mounting hardware. Two brackets are provided for mounting the
serial server flush to a panel or behind a rack-mount instrument panel.
Figure 10. Panel Mount Brackets
Each bracket is mounted using two 4-40 flat-head screws (included). The
additional threaded holes on the side of the serial server allow the unit to be
mounted in six different configurations.
Figure 11. VESR4x4 showing Panel Mount Bracket options
If extra mounting brackets are needed, they can be ordered from B&B
Electronics as Kit Number #9030.
The DIN rail mounting bracket attaches to the back of the serial server using
three 4-40 flat head screws.

SECTION 3
Installation and Initial Setup
This section describes how to install the VESR4x4 Serial Server and configure
the device.
Note: In this section devices to be connected to the serial server’s serial connections are simply referred
to as the “serial device”.
Connecting the Power Supply
Connect a DC power supply to the power terminals on the side of the serial
server. Polarity of the wires is indicated underneath each connector.
Acceptable voltages are between 10 VDC and 58 VDC. The power supply must
be capable of supplying 6 watts.
Figure 13. Power Supply Connections
Connecting VESR4x4 Serial Servers to Serial Devices
VESR4x4 Serial Servers can be connected to serial devices using RS-232, RS-
422, RS-485 2-wire, or RS-485 4-wire communication. VESR4x4D models use
DB-9M connectors and VESR4x4T models use 5-position terminal strips.
RS-232
Models using DB9M connectors support seven RS-232 signal lines (TD, RD,
DTR, DSR, RTS, CTS, DCD) plus Signal Ground.
Models using five position pluggable terminal blocks support four signal
lines (TD, RD, RTS, CTS) plus Signal Ground.

Section 3 - Installation and Initial Setup Vlinx VESR4x4 Serial Server
Page 20 of 70
www.bb-elec.com/
www.bb-europe.com/
Signals are single-ended and referenced to Signal Ground. Default
communications parameters are 9600, 8, N, 1 (9600 baud, 8 data bits, no
parity, 1 stop bit), and no flow control.
Note: The VESR4x4 is configured as a DTE. If it is connected to a computer or other DTE device, use a
null modem (cross-over) cable. If the serial device is configured as a DCE, use a straight-through
cable.
RS-422
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. In RS-422, the
transmitter is always enabled. Signal Ground provides a common mode
reference for the signal lines.
RS-485
RS-485 connections support 2-wire or 4-wire operation. In RS-485 mode, the
transmitter is only enabled when the serial server is transmitting data on the
line. This allows other devices to share the bus.
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. Signal Ground
provides a common mode reference for the signal lines.
When configured for 2-wire operation the connection supports one signal
pair: Data A (-) and Data B (+). These lines transmit and receive signals using
half-duplex operation. The data lines are differential with the Data B line
positive relative to Data A in the idle (mark) state. Signal Ground provides a
common mode reference for the signal lines.
