NETWORK PROTOCOLS
Network Protocols
available for use on VESR9xx serial servers include TCP, UDP,
VCOM and Paired Mode.
NETWORK WATCHDOG
Network Watchdog
controls the duration of network inactivity when a network
connection is determined idle and causes the connection to be forced closed. The
range is 1 through 65535 milliseconds.
PAIRED MODE
Paired Mode
enables two serial servers to operate across the network like a "wire
replacement" between two serial devices. (Paired Mode is also called SERIAL
TUNNELING .) Serial devices connected to serial servers on each end of the link can
communicate as it they were connected by a serial cable.
For Paired Mode to work one serial server must be configured as a TCP server and
the other as a TCP client.
The serial server configured as the
TCP client initiates connections. You must set up
the IP address and port number of the server that you want the client (serial server)
to communicate with. You also select whether you want the serial server to connect
at power up or only when it receives data from the device connected to its serial
port.
The serial server configured as a
TCP server waits for connections to be initiated by
another network device. You must set up the TCP port number on which it will listen
