Operation

A detailed operating manual is contained on the CD ROM which ships with the product.

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 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

ESP901/ESP902/ESP904 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/ESP904 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
