Pair Connection Mode

Pair Connection Mode employs two NPort 5600 device servers in tandem, and can be used to remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5600 is connected from its RS-232 port to the COM port of a PC or other type of computer, such as hand-held PDAs that have a serial port, and the serial device is connected to the RS-232 port of the other NPort 5600. The two NPort 5600 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 NPorts.

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 5600 device servers. In effect, this NPort 5600 will be acting as a TCP client.
