Operation

A detailed operating manual is contained on the CD ROM which ships with the product.

Vlinx
TM
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.
