Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
Page 17 of 69 www.advantech-bb.com
SECTION 3
Initial Setup and Connections
This section describes how to setup and connect VESP211 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 by plugging a 12 VDC power source into the
barrel jack on the top of the serial server. The center connection must be
positive (+). (Polarity of the connection is indicated on the label on the front of
the serial server.) The power supply must be capable of supplying 2.5 watts
maximum.
Connecting VESP211 Serial Servers to Serial Devices
VESP211 Serial Servers can be connected to serial devices using RS-232, RS-
422, RS-485 2-wire and RS-485 4-wire.
RS-232
The RS-232 interface supports seven RS-232 signal lines (TD, RD, DTR,
DSR, RTS, CTS, DCD) plus Signal Ground.
Signals are single ended and referenced to Ground. Default communications
parameters are 9600, 8, N, 1 and no flow control implemented.
Note: The VESP211 is configured as a DTE. If it is connected to a serial device configured as a DTE, use
a null modem (cross-over) cable. If the serial device is a DCE, use a straight-through cable.
RS-422
The RS-422 interface supports 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.
Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
Page 18 of 69 www.advantech-bb.com
RS-485
The RS-485 interface supports 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.
Note: Refer to Appendix D for connector pinout information.
Network
Figure 10. VESP211 Connections
Connecting VESP211 Serial Servers to a Network
Ethernet Connection (10BaseT/100BaseTX)
The Ethernet connection uses a standard 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.

Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
Page 19 of 69 www.advantech-bb.com
VESP211 Serial Server Configuration Connections
VESP211 Serial Servers can be configured using several methods:
• Via the network using Vlinx Manager software
• Via the network using a web browser
• Via the serial port using Vlinx Manager software (Console Mode)
Configuring via the Network using Vlinx Manager
VESP211 Serial Servers can be configured over the network using Vlinx
Manager software running on a networked PC. Vlinx Manager includes a
discovery function that makes it possible to detect the serial server on the
network whether you know its IP address or not. Once the serial server has
been detected, the Manager can be used to configure its settings.
Note: For more information on how to use Vlinx Manager to configure your serial server, refer to Section 4:
Configuring the Serial Server
Network
Figure 11. Network Setup
Configuring via the network using a Browser
VESP211 Serial Servers can also be configured over the network using a
standard internet browser such as Internet Explorer or Firefox running on a
networked PC. To do so you must know the IP address of the serial server.
Your serial server comes from the factory pre-configured to receive an IP
address from a DHCP Server. If DHCP assignment is not available it will
default to 169.254.102.39

Note: For more information on how to use Vlinx Manager to configure your serial server, refer to Section 4:
Configuring the Serial Server
Configuring via the Serial Port using Vlinx Manager (Console Mode)
Your serial server can be configured via the serial port using Vlinx Manager. To
use this feature the serial port must be connected to the serial port of a PC
(using a null modem cable).
Figure 12. Console Mode Setup
To configure the serial server it must be put into Console Mode, using the
Reset switch.
Note: Refer to Section 2 for information on how to use the Reset switch to enter Console Mode.
VESP211 Serial Server Operational Connections
VESP211 Serial Servers can operate in Direct IP, Virtual COM Port and Paired
Modes.
In Direct IP Mode applications using TCP/IP or UDP/IP socket programs can
communicate with the COM 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.
Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
Page 21 of 69 www.advantech-bb.com
Network
Figure 13. Direct IP and Virtual COM Port Connection
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.
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 is set up as shown in the following diagram and configured using Vlinx
Manager software or web interface.

TCP Configuration
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 you configure the serial server 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 you want the serial server 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 eight)
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 Configuration
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.
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.)

Setting up Virtual COM (VCOM) Operation
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.

Setting up Paired Mode Operation
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 the connection. 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.

Page 51 of 69 www.advantech-bb.com
SECTION 8
Description of Serial Server Properties
The following serial server properties are ordered alphabetically to assist you
in finding the information you need.
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 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
8192.
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 Bits. 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.)
The Default Gateway address sets the default route to remote networks,
enabling users to access the serial server from outside the local network.
Section 8 - Description of Serial Server Properties Vlinx VESR4x4 Serial Server
Page 52 of 69 www.advantech-bb.com
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
recognizes the specified character(s) on its serial port.
• Delimiter 1 is a start delimiter. The range of ASCII values is 1 through
255.
• Delimiter 2 is an end delimiter. The range of ASCII values is 1 through
255.
• 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 delimiter 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 (Dynamic Host Configuration Protocol) is a protocol used on special
servers that supply IP addresses to network nodes on request.
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.

Section 8 - Description of Serial Server Properties Vlinx VESR4x4 Serial Server
Page 53 of 69 www.advantech-bb.com
Note 1: 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.
Note 2: 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 IP address of the serial server, and the IP
address has been changed, the device will not be able to communicate with the serial server.
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 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 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.
The Hardware Version number of the serial server hardware is displayed on
the Login page of Vlinx Manager.
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.

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.
f. Open the Vlinx™ Manager Software and select Serial Port as the
method to connect to the device.
g. After logging in, click Network.
h. De-select I want DHCP to setup the Network.
i. Re-configure the serial server’s network settings to an address within
the range of your PC’s network setting.
For example, if your PC is configured to the following settings:
IP Address = 192.168.0.1
Network Mask = 255.255.255.0
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
• Save the settings and remove power from the serial server.
• 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 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.
Section 8 - Description of Serial Server Properties Vlinx VESR4x4 Serial Server
Page 56 of 69 www.advantech-bb.com
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 its own unique MAC address. The MAC address of each serial server is
printed on the device's label. The MAC address of each device is shown in the
Serial Server Information Table. The MAC address of the currently selected
serial server is also displayed on the Login page of Vlinx Manager.
The Model number of the currently selected serial server is displayed on the
Login page of Vlinx Manager.
Network Protocols available for use on VESP211 serial servers include TCP,
UDP, VCOM and Paired Mode.
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 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 eight) 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 VESP211 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. 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
Section 8 - Description of Serial Server Properties Vlinx VESR4x4 Serial Server
Page 57 of 69 www.advantech-bb.com
kbaud over short distances (typically 50 feet). Typically uses DB-9
connectors but terminals are also used on VESP211 serial servers.
• RS-422 - Point-to-point communications using a transmit pair and a
receive pair. RS-422 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 VESP211 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 VESP211
serial servers.
• RS-485 4-wire - Similar speed and distance specifications as RS-422
but allows full-duplex connections. Typically uses two shielded twisted
pairs and screw terminals but DB-9 connectors are also used on VESP211
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 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.
The Server Serial Port Number of the currently selected port is shown in
this field. For more information refer to the TCP/UDP Ports table in Appendix
B, which shows the ports used for several modes of operation.
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.
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
Section 8 - Description of Serial Server Properties Vlinx VESR4x4 Serial Server
Page 58 of 69 www.advantech-bb.com
• 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.
• VESP211serial servers come from the factory with a default subnet mask
value of: 255.255.255.0
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.
TCP client. 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.
TCP server. 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 eight) 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) 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.)
• 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.
• 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.
Section 8 - Description of Serial Server Properties Vlinx VESR4x4 Serial Server
Page 59 of 69 www.advantech-bb.com
• 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.

This port is open when serial port 1 is
configured for paired-mode server.
These ports are used to transfer handshake line state and break state in
paired mode configuration. These ports are open only if you configure
the port for paired-mode server. Note that serial port 1 uses 60000/tcp,
serial port 2 uses 60001/tcp, serial port 3 uses 60002/tcp and serial port
4 uses 60003/tcp. If a port is not configured for paired-
mode server, then
the corresponding port is not open.
If you want to connect to a paired-
mode server from outside of a firewall,
then you must allow incoming connections on these ports.
If you want to connect to a paired-mode server from outside of a NAT,
then you must forward to these ports.
60001/tcp
This port is open when serial port 2 is
configured for paired-mode server.
Not Applicable
60002/tcp
This port is open when serial port 3 is
configured for paired-mode server.
Not Applicable
60003/tcp
This port is open when serial port 4 is
configured for paired-mode server.
Not Applicable
68/udp
This port is open when the network
mode is DHCP.
This port is used if you configure the device for DHCP mode (as
opposed to Static IP). It is used to communicate with the DHCP server.
This should only be used inside of a firewall or NAT.
7000/udp
Always open for serial server
configuration over UDP.
These ports are used for configuration and firmware upgrade of the
device using the serial server manager. These ports are always open no
matter how you configure the device.
If you want to configure the serial server from outside of a firewall using
the serial server manager, then the firewall must be configured to allow
incoming connections on 7000/tcp and allow packets addressed to
7000/udp to be received

8899/udp
Always open for serial server discovery.
This port is used for discovering serial servers. This port is always open
no matter how you configure the device.
Note: The device discovery only works on a local subnet. The port may
not need to be configured in a firewall or NAT.
Other
User-specified ports.
Other TCP and UDP ports may be open depending on what you specify
for the device configuration. THESE ARE THE PORTS SPECIFIED IN
THE CONFIGURATION FILE.
If you want to use these other ports from outside of a firewall, then you
must allow these ports.
If you want to use these other ports from outside of a NAT, then you
must forward to these ports

Note 1: In the RS-422 mode, TX lines are outputs and RX lines are inputs. Connect the serial server TDB(+)
line to the RDB(+) line of the serial device, and the serial server TDA(-) to the RDA(-) of the serial
device.
Note 2: Ground is signal ground and provides a common mode reference for the RS-422 Receiver and
Transmitters.
