Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
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, RS422, 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.
Page 15 of 66 Manual Documentation Number: VESP211-5011m
www.bb-elec.com/
www.bb-europe.com/
Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
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.
Figure 9. 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
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
Figure 10. 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

Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
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 11. 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.

www.bb-europe.com/
Section 3 - Initial Setup and Connections Vlinx VESR4x4 Serial Server
Figure 12. 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.
