This Ethernet Serial Server was designed especially for Industrial
applications. Features like a thin-profile DIN mount case, IP30 rating,
wide temperature range and wide range, redundant power supply make the
Vlinx® ESR series Industrial Ethernet Serial Servers the best fit for
industrial users.
Use the ESR to convert Ethernet to RS232 or convert Ethernet to RS485
to connect PLC's, CNC machines, HMI panels or any other industrial
equipment that has an RS232, RS422 or RS485 serial port to the LAN. By
installing an ESR Ethernet Serial Server you'll be able to communicate
with that equipment from anywhere on the LAN or WAN, eliminating trips
out to the plant for programming, diagnostics or data gathering.
No software changes required, the ESR can be transparent to your
existing software making installation quick and easy. Your office or
control room PC will show the device as if it had a direct serial
communications connection to monitor and fine tune it. You can even
troubleshoot the distant device from outside your LAN via the Internet.
Vlinx™ Manager Software
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.
Web Server
ESR serial servers can be accessed and configured from an Internet
Explorer web browser on the LAN/WAN. This allows you to remotely manage
the software and your serial device. It also allows off-site
troubleshooting.
Heartbeat Connection Protection
When there is an interruption in communication the Serial Server will
attempt to reconnect the TCP data connection 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 paired mode.
