ESR Series Industrial Ethernet Serial
Server
B&B Electronics
The ESR series devices are serial servers
that provide RS-232 to Ethernet
conversion and transport of serial data
over an IP network. ESR devices are
available in 1, 2 or 4 port versions.
Directions included below may also be
found in the Quick Start Guide and the
User’s Guide along with more detailed
information about the device. Both
documents are shipped with the ES1A
and are available on the B&B Electronics
website at http://www.bb-elec.com.
Cabling
The ESR has a DB-9 connector on one
end and the RJ-45 Ethernet connector on
the other end. Use the standard serial
cable as described on page 3.
Network Configuration
The ESR must be setup to ensure the
proper serial port settings are configured
to communicate with the Opticom™
Infared phase selector over the RS-232
interface and that the proper network
configurations are made to allow the ESR
to be found on the network by central
management software. The unit must be
configured with a static IP address. On
the “Operations” web page:
Set DHCP to Disable.
Specify the IP address to be used by this
device.
Specify the Netmask (usually
255.255.255.0).
Specify the Default Gateway.
Refer to the User’s Guide for instructions
on how to access the configurations via
the internal web pages.
Serial Port Configuration
The Serial Port configuration specifies the
type of transport communications means
which will be used to ferry the RS-232
serial data over the IP network.
On the “Serial” web page, set Serial port
mode to RS-232. Configure the
remaining serial as described in the
Required Serial Settings on page 3.
To use TCP/IP protocol, open the
“Operation” web page, then select “TCP”
and set Connection mode to Server. Use
defaults for the other fields.
Installation of VLINX Virtual COM Port
software allows the remote devices to be
installed as COM ports on a PC or server.
Tracer IP is sold separately. GTT has not
tested VLINX Virtual COM Port software.
