conflicts with well known UDP ports, the default is set to 4001.
Pair Connection Mode
Pair Connection Mode employs two NPort 5400 device servers in tandem, and can be used to
remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5400 is
connected from its RS-232 port to the COM port of a PC or other type of computer, such as a
hand-held PDA, and the serial device is connected to the RS-232 port of the other NPort 5400. The
two NPort 5400 device servers are then connected to each other with a cross-over Ethernet cable,
both are connected to the same LAN, or in a more advanced setup, they communicate with each
other over a WAN (i.e., through one or more routers). Pair Connection Mode transparently
transfers both data and modem control signals (although it cannot transmit the DCD signal)
between the two NPort device servers.
Pair Connection Master Mode
When using Pair Connection Mode, you must select Pair Connection Master Mode for the
Operation mode of one of the NPort 5400 device servers. In effect, this NPort 5400 will be acting
as a TCP client.
