What is Pair Connection Mode?

The Pair Connection Master and Slave modes connect two NPort device servers over an
Ethernet network for serial-to-serial communication. The two NPort device servers can
connect to each other with an Ethernet cable, connect to the same LAN, or in a more
advanced setup, communicate with each other over a WAN (i.e., through one or more
routers). A device attached to one NPort can then communicate transparently with a
device attached to the other NPort, as if a serial cable connected the two devices. Both
data and modem control signals are transmitted, although DCD signals are not. NPort's
Pair Connection modes can overcome the distance limitations inherent in serial
communication and introduce many new possibilities for serial-based device control.
