VESR9xx Serial Servers
28
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 for connections and set the maximum (up
to four) number of simultaneous connections it will accept. You can filter
the connections it will accept based on specific IP addresses or ranges
of IP addresses that you specify.
PASSWORD
When you first receive the VESR9xx serial server from the factory, the
Password is blank so that you can initially access the serial server
without entering a value into this field. To ensure security, you should
create and save a password the first time you configure the serial server.
After a password has been set up, it must be entered each time you login
to Vlinx Manager. The password is used to access the configuration
pages from the Vlinx Manager Login page and can be changed from the
General page.
