Functional Description
Industrial and commercial measurement and control systems often have standalone devices with unused
serial ports. B&B Electronics ESR Serial Servers allow you to connect those ports into your existing LAN or
WAN, giving you access to more information and the ability to configure, manage and troubleshoot those
devices from a control room, office or even a distant location via a WAN. Save the cost, time and trouble of
carrying a laptop out to devices located in distant, cold, dirty or uncomfortable environments.
ESR Serial Servers are built for use in industrial environments, featuring an IP30 approved slim line DIN rail
mountable case. They operate from a range of voltages using AC or DC power, feature terminal block
power connectors and even support redundant DC power.
Connect your serial device to the ESRs serial port and connect the ESR to your LAN. Your networked
computer sees the device over the network as a virtual serial connection. ESR serial servers support TCP
or UDP protocols and allow transmitting to and receiving from multiple IP addresses. There are four
methods of configuring ESR serial servers: via Vlinx Management Software, Web Server, Telnet or via a
direct RS-232 console connection using a terminal program

Vlinx Manager Software allows easy access to the serial server to configure the server and its
ports, upgrade server firmware and monitor port status and activity. When the Vlinx Manager opens
it will search for and display all serial servers on the network. The Monitor Port feature allows you to
use any PC on the LAN/WAN to actively view and troubleshoot the communications status. It
shows when there is a client connection to the server and the client IP address. It displays the
number of bytes transmitted and received as well as the status of the hardware handshaking lines
ESR serial servers can be accessed and configured from any web browser (such as Internet
Explorer) on the LAN/WAN. This allows you to remotely manage the software and your serial
device. It also allows off-site troubleshooting
Vlinx Serial Servers provide automatic resumption of the TCP data connection in case of a power
failure or loss of an Ethernet connection on either the client or server. Once the Heartbeat
connection is established, the server sends a signal to the client every five seconds until
communication is re-established. Without this feature a device that loses a connection and stops
communicating would not be able to reconnect without a person attending to the problem. The
Heartbeat feature works with virtual COM and TCP direct IP connections.
