Now you can Ethernet enable any serial device. Use B&B’s Vlinx Serial Server technology to
put your serial ports to work for you. Imagine the ability to communicate with every piece of
equipment from any networked PC. Eliminate site visits just to find a need to make a minor
configuration change. Reduce service calls and increase productivity by knowing what your
equipment is doing before you get a trouble-report. Spend more time doing the work you’re
paid to do instead of chasing down nuisance problems with remotely located equipment.
Do you have equipment with serial ports that you have left unconnected? Much of today’s high-tech equipment ships
with a serial port for programming, monitoring or diagnostics. 80% of these serial ports are left unconnected, often
because a person travels to the port to make the connection or a permanent PC is not desirable. With B&B’s Vlinx
Serial Servers, you can put all of those ports to work for you.
Simply connect the Vlinx server to the equipment’s serial port, and connect the Vlinx Ethernet port to your LAN. Your
equipment is now online. It will appear as a local COM port on any networked PC running our Virtual Serial Port
software. No software customization required, just run the appropriate software for your equipment.
B&B Electronics'new Models ESP901 (single port) and ESP902 (dual port) integrate the benefits of Ethernet
communications with existing serial devices by offering the combination of three serial interfaces, RS-232, RS-422, and
RS-485. The Ethernet connection will auto select 10BaseT or 100BaseTX.
ESP901/ESP902 serial servers provide Windows host control over serial devices located virtually anywhere on a
TCP/IP or UDP/IP Ethernet connection. They even give authorized users control over the connected serial device and
the server configuration from anywhere outside the LAN.

Vlinx ESP Manager allows easy access to the serial server to
configure the server and ports, upgrade server firmware and
monitor port status and activity. When ESP Manager opens it
will search for and display all ESP90x serial servers on the
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.
ESP901/ESP902 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.

ESP901/ESP902 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. If the signal is not received, the serial server will attempt to reconnect
the TCP data connection every five seconds until communication is established again.
