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

Setup and Connections
Figure 18. Direct IP and Virtual COM Port Connection
USING VESR9XX SERIAL SERVERS IN VIRTUAL COM PORT MODE
In Virtual COM Port Mode a PC can communicate across the network to the serial
server as if the serial ports on the serial server are the PC’s serial ports. When a
virtual COM port is configured on the PC (using Vlinx Manager) a new COM port
appears 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 directly with the remote serial device connected to
the serial server.
To set up a Virtual COM Port Mode connection:
1.
Connect the serial server to the network and a serial device as
described in previous sections.
2.
Configure the serial server for VCOM operation (using Vlinx Manager).
3.
Configure your software application to communicate via the virtual
COM port.
USING VESR9XX SERIAL SERVERS IN PAIRED MODE
When using serial servers in Paired Mode, two serial servers (connected to serial
devices via their serial ports) are connected to the network. The serial devices
communicate directly, transferring data between devices as a point-to-point serial
connection. Paired Mode set up as shown in the following diagram and configured
using Vlinx Manager software or web interface.

Serial Server Properties
DESCRIPTION OF SERIAL SERVER PROPERTIES
The following serial server properties are ordered alphabetically to assist you in
finding the information you need.
BAUD RATE
Baud Rate is the communication speed of the link between the serial server and the
device attached to its serial port. Both these devices must be configured to operate
at the same baud rate. Baud rate values range from 75 to 230,400 Baud. (Refer to
Appendix B for specific baud rates that are supported.)
CHARACTER COUNT
Character Count controls the maximum number of characters to buffer before
sending the characters to the network. Larger values decrease the number of
network packets, but increase the amount of time to receive characters. Smaller
values increase the number of network packets, but decrease the amount of time to
receive characters. The range is 1 through 65535.
CONFIGURATION FILES
Configuration files contain all configuration settings for the serial server. When the
serial server settings have been configured you can save the settings using Vlinx
Manager. Existing configuration files can be Opened (from Vlinx Manager), which
loads them into the serial server. This allows the same configuration to be applied to
multiple serial servers, or to reload a previously used configuration.
DATA/PARITY/STOP
The number of Data bits, type of Parity and number of Stop bits selected define the
serial port parameters at which the serial server will operate. These parameters must
be configured to match the parameters set on the serial device connected to the
serial server's serial port.
Data Bits controls the number of bits of data in each character. Options include 5, 6,
7 or 8 data bits.
Parity controls the error checking mode. Options are No Parity, Odd, Even, Mark or
Space.
Stop Bits controls the number of bits to indicate the end of a character. Options
include 1, 1.5 and 2. (1.5 bits is only valid when 5 data bits is selected, which is rare.
The 2 stop bits setting is only valid when 6, 7 or 8 data bits is selected.)
DEFAULT GATEWAY
www.bb-elec.com
www.bb-europe.com
25
Serial Server Properties
The Default Gateway address sets the default route to remote networks, enabling
users to access the serial server from outside the local network.
DELIMITER 1, DELIMITER 2 AND DELIMITER REMOVAL
Delimiters and Delimiter Removal enable you to control how characters received on
a serial port are sent across the network. Delimiters are ASCII characters specified by
the user when configuring the serial server. The serial server takes action when it
recognises the specified character(s) on its serial port.
DELIMITER 1
Delimiter 1 is a start delimiter. The range of ASCII values is 0 through 255.
DELIMITER 2
Delimiter 2 is an end delimiter. The range of ASCII values is 0 through 255.
DELIMITER REMOVAL
Delimiter Removal controls removing of Delimiter 1 and Delimiter 2 from the
received characters before the received characters are sent to the network.
HOW DELIMITERS WORK
When only Delimiter 2 (the end delimiter) is enabled, characters received by the
serial port are accumulated in a buffer. When the end delimiter is received on the
serial port, the buffered characters, including the end delimiter, are sent to the
network. All characters received after the end delimiter are again buffered until
another end delimter is received.
When both Delimiter 1 (start delimiter) and Delimiter 2 (end delimiter) are enabled,
characters received by the serial port will be discarded until the start delimiter
character is detected on the serial port. The serial server then buffers the start
delimiter character and all subsequent characters received after it until the end
delimiter is detected. When the end delimiter is received, the buffered characters,
including the start and end delimiters, are sent to the network.
When Delimiter Removal is enabled it removes the delimiter character(s) before
sending the other characters across the network.
DHCP
DHCP (Dynamic Host Configuration Protocol) is a protocol used on special servers
that supply IP addresses to network nodes on request.
www.bb-elec.com
www.bb-europe.com
26
Serial Server Properties
When DHCP is enabled on the serial server, on power up it sends a DHCP request to
the DHCP server, which assigns a dynamic IP address, subnet mask, and default
gateway to the serial server.
When DHCP is disabled (static IP addressing), the IP Address, Subnet Mask and
Default Gateway fields must be set manually by entering the appropriate addresses
in these fields. If you do not know what addresses to use in these fields, ask your
network administrator.
Notes:
This product is factory defaulted to the DHCP mode. It is intended that your network’s DHCP
Server provide the IP address assignment. If there is not a DHCP server on your network, the
device will default to IP address 169.254.102.39.
A dynamic address assigned by the DHCP server may change if the server loses the Ethernet
connection or power is removed. If a device on the network that normally communicates with
the serial server is configured to communicate with a specific IPaddress of the serial server,
and the IP address has been changed, the device will not be able to communicate with the
serial server.
FIRMWARE VERSION
The Firmware Version number (Vx.x.x) indicates the serial server's currently loaded
firmware release. From time to time new firmware is made available and can be
uploaded into the serial server using Vlinx Manager.
FLOW CONTROL
Flow Control determines the type of handshaking that is used to control sending and
receiving of messages. Options include No Flow Control, Hardware Flow Control
(RTS/CTS) and Software Flow Control (XON/XOFF). The Flow Control setting must
match the requirements of the serial device connected.
Note: Select No Flow Control when setting the port as RS-422 or RS-485 4-wire.
FORCED TRANSMIT
Forced Transmit controls the maximum amount of time that characters can be
buffered before sending the characters to the network. Larger values decrease the
number of network packets, but increase the amount of time to receive characters.
Smaller values increase the number of network packets, but decrease the amount of
time to receive characters. The range is 1 through 65535.
HARDWARE VERSION
www.bb-elec.com
www.bb-europe.com
27
Serial Server Properties
The Hardware Version number of the serial server hardware is displayed on the
Login page of Vlinx Manager.
INTER-CHARACTER TIMEOUT
Inter-character Timeout controls the maximum duration between received
characters before sending the characters to the network. Larger values may decrease
the number of network packets, but increase the amount of time to receive
characters. Smaller values may increase the number of network packets, but
decrease the amount of time to receive characters. The range is 1 through 65535.
IP ADDRESS
Software or hardware attempting to access the serial server via the network must
know the IP Address of the server. In DHCP mode (factory default), the serial server
requests and receives a dynamic IP address from a DHCP server when it first
connects to the network. If there is not a DHCP Server on your network, this device
will automatically default to IP Address 169.254.102.39. If the serial server is unable
to connect to your network using this address, there are two methods to manually
configure the IP Address.
1. Method One: Change your PC Network to Match the Serial Server
a. Open the network connection on your PC
b. Click on Internet Protocol (TCP/IP) and click <Properties>.
Change the parameters to the following:
IP Address = 169.254.102.1
Subnet Mask = 255.255.255.0
Default Gateway = 169.254.102.100

c. Use
the
Vlinx™ Manager Software to search for, discover, and
configure the unit.
2. Method Two: Change the serial server’s network setting to match
your PC using Console Mode
a. Connect a null modem serial cable (crossover cable) from
Port 1 on the serial server to an available COM port on
your PC.
b. Open Hyper Terminal or similar serial emulation software
and connect to the COM port used in the step above.
Ensure the port is configured to 115,200 baud, 8 data
bits, and 1 stop bit.
c. Enter Console Mode. Press and hold the serial server’s
RESET SWITCH for 2 to 10 seconds. The LED indicators will
respond as follows:

d. Release the RESET button. The READY LED will blink once
per second for 5 seconds. This indicates that the serial
server is re-booting in Console Mode.
e. When the serial server has successfully restarted in
Console Mode, the READY LED will be OFF and the PORT 1
LED will be on.

Default Gateway = 192.168.0.100
Configure the serial server to:
IP Address = 192.168.0.50
Network Mask = 255.255.255.0
Default Gateway = 192.168.0.100
j.
Save the settings and remove power from the serial
server.
k. Apply power to the serial server. Open the Vlinx™
Manager Software and select “Network” as the method
to connect to the serial server
LINK STATUS
Link Status of the currently selected serial server is shown on the Login page of Vlinx
Manager. Link status indicates the type of Ethernet connection between the
computer and serial server. It will either display 10BaseT or 100BaseTX in full duplex
or half duplex. Link status is dependant on the LAN, switches, hubs used in the LAN
topology.
MAC ADDRESS
The MAC Address is a hardware level address of the serial server that cannot be
changed. It is assigned in the factory. Every Ethernet device manufactured has it own
unique MAC address. The MAC address of each serial server is printed on the
device's label. The MAC address of the currently selected serial server is also
displayed on the Login page of Vlinx Manager.

Serial Server Properties
The Model number of the currently selected serial server is displayed on the Login
page of Vlinx Manager.
NETWORK PROTOCOLS
Network Protocols available for use on VESR9xx serial servers include TCP, UDP,
VCOM and Paired Mode .
NETWORK WATCHDOG
Network Watchdog controls the duration of network inactivity when a network
connection is determined idle and causes the connection to be forced closed. The
range is 1 through 65535 milliseconds.
PAIRED MODE
Paired Mode enables two serial servers to operate across the network like a "wire
replacement" between two serial devices. (Paired Mode is also called SERIAL
TUNNELING.) Serial devices connected to serial servers on each end of the link can
communicate as it they were connected by a serial cable.
For Paired Mode to work one serial server must be configured as a TCP server and
the other as a TCP client.
The serial server configured as the TCP client initiates connections. You must set up
the IP address and port number of the server that you want the client (serial server)
to communicate with. You also select whether you want the serial server to connect
at power up or only when it receives data from the device connected to its serial
port.
The serial server configured as a TCP server waits for connections to be initiated by
another network device. You must set up the TCP port number on which it will listen
for connections and set the maximum (up to four) number of simultaneous
connections it will accept. You can filter the connections it will accept based on
specific IP addresses or ranges of IP addresses that you specify.
PASSWORD
When you first receive the VESR9xx serial server from the factory the Password is
blank so that you can initially access the serial server without entering a value into
this field. To ensure security you should create and save a password the first time
you configure the serial server. After a password has been set up it must be entered
each time you login to Vlinx Manager. The password is used to access the
configuration pages from the Vlinx Manager Login page and can be changed from the
General page.
SERIAL INTERFACE MODES
www.bb-elec.com
www.bb-europe.com
31
Serial Server Properties
Four serial interface modes of operation are:
RS-232 - Point-to-point serial communications connection used by PC COM ports and
many other systems. Capable of baud rates up to 115.2 kbaud over short distances
(typically 50 feet). Typically uses DB-9 connectors but terminals are also used on
VESR9xx serial servers.
RS-422 - Point-to-point communications using a transmit pair and a receive pair. RS422 can operate at higher speeds and longer distances than RS-232. Typically uses
two shielded twisted pairs and screw terminals but DB-9 connectors are also used on
VESR9xx serial servers.
RS-485 2-wire - Similar speed and distance specifications as RS-422 but allows
multidrop connections. Typically uses one shielded twisted pair and screw terminals
but DB-9 connectors are also used on VESR9xx serial servers.
RS-485 4-wire - Similar speed and distance specifications as RS-422 but allows fullduplex connections. Typically uses two shielded twisted pairs and screw terminals
but DB-9 connectors are also used on VESR9xx serial servers..
Select the appropriate serial interface mode for the type of connection between the
serial server's serial port and the device connected to it.
Note: Refer to the Appendix D for connector and pin-out details.
SERIAL SERVER NAME
Serial Server Name is a unique name assigned to the serial server. It must be a valid
hostname as defined by RFC-952 and RFC-1123. The rules are:
It must consist only of the characters "A" to "Z", "a" to "z", "0" to "9" or "-"
It can start or end with a letter or a number, but it must not start or end with a "-".
It must not consist of all numeric values.
SERVER SERIAL PORT NUMBER
The Server Serial Port Number of the currently selected port is shown in this field.
VESR901-x serial servers feature one serial port.
VESR902D-x and VESR902T-x serial servers feature two serial ports.
SERIAL WATCHDOG
Serial Watchdog controls the duration of serial inactivity when the serial port is
determined idle and causes all connections for that serial port to be forced closed.
The range is 1 through 65535 milliseconds.
www.bb-elec.com
www.bb-europe.com
32
Serial Server Properties
SUBNET MASK
The Subnet Mask specifies the network mask the serial server uses when on a
subnetted network.
For a Class A network (IP addresses 0.0.0.0 through 127.255.255.255) the default
subnet mask is 255.0.0.0.
For a Class B network (IP addresses 128.0.0.0 through 191.255.255.255) the default
subnet mask is 255.255.0.0
For a Class C network (IP addresses 192.0.0.0 through 233.255.255.255) the default
subnet mask is 255.255.255.0
For a Class D network (IP addresses 224.0.0.0 through 239.255.255.255) and Class E
Networks (IP addresses 240.0.0.0 through 255.255.255.255) the subnet mask is
ignored.
VESR9xxserial servers come from the factory with a default subnet mask value of:
255.255.255.0
TCP (TRANSMISSION CO NTROL PROTOCOL)
TCP (Transmission Control Protocol) provides reliable connection-oriented network
communication with error checking. In TCP mode the serial server can be configured
as a client or a server.
When the serial server is configured as a TCP client it initiates connections with a
server on the network. You must set up the IP address and port number of the server
that you want the client (serial server) to communicate with. You also select whether
the serial server is to connect at power up or only when it receives data from the
device connected to its serial port.
When the serial server is configured as a TCP server it waits for connections to be
initiated by another network device. You must set up the TCP port number that it will
listen to for connections and set the maximum (up to four) number of simultaneous
connections it will accept. You can filter the connections it will accept based on
specific IP addresses or ranges of IP addresses that you specify.
UDP (USER DATAGRAM PROTOCOL)
UDP (User Datagram Protocol) enables applications using UDP socket programs to
communicate with the serial ports on the serial server. UDP protocol provides
connectionless communications, which allows data to be broadcast to and received
from multiple nodes on a network. (Because it is a connectionless protocol UDP does
not guarantee the delivery of a datagram and the datagram is only be sent once.)
www.bb-elec.com
www.bb-europe.com
33
Serial Server Properties
In UDP mode, if you want to control what network node receives data, you must
specify the IP address and UDP port the data will be sent to. You can choose to send
to:
Nobody
All nodes at a specific UDP port number. (This is called broadcast.)
Specific IP addresses and UDP port numbers. (This is called unicast.)
A range of IP addresses and UDP port numbers. (This is called unicast range.)
You can also configure the serial server to receive from nodes on the network using
the same list of configuration options.
VCOM (VIRTUAL COM PORT)
When the Network Protocol is set to VCOM (Virtual COM Port) the serial server
communicates over the network with a PC, acting as a remote COM port for the
computer.
Both the serial server and the computer must be configured for VCOM operation.
Virtual COM ports can be set up on the PC using the Vlinx Manager software.

In the RS-422 mode, TX lines are outputs and RX lines are inputs. Connect the serial
server TXB(+) line to the RXB(+) line of the serial device, and the serial server TXA(-)
to the RXA(-) of the serial device.
Ground is signal ground and provides a common mode reference for the RS-422
Receiver and Transmitters.
