If are using a multiport serial board installed in a UNIX host, but wish to extend the device control
range without dismantling the host, you can accomplish this with CN2510. Multiplex and
De-multiplex solutions use CN2510’s RTelnet and terminal modes, eliminating the need to modify
existing software. CN2510 acts like a converter by extending the communication distance.
CN2510s work in pairs over the network to overcome the short communication distance limitation
imposed by serial connections.
See Chapter 12 for detailed configuration instructions.
NOTE: This mode does not allow copying the status of control signals to devices at a remote site.
