3.4 Station Manager Port
The RX7i and rack-based RX3i Ethernet interfaces provide a dedicated RS-232 serial port for local Station
Manager use. This nine-pin D connector accepts a standard straight-through nine-pin RS-232 serial cable to
connect to a standard AT-style RS-232 port.
The following cable is available:
IC200CBL001 Cable, CPU Programming
Port Settings
The serial (COM) port of the terminal or computer that is connected to the Ethernet Interface must use the
same communications parameters as the Ethernet Interface.
The default values for the Station Manager port are 9600 bps, 8 bits, no parity, and 1 stop bit. If the Ethernet
Interface is configured with default values for this port, or the Ethernet Interface has not been configured, use
these default values. If the Ethernet Interface is configured with non-default values for this port, use those
values for the serial port settings of the terminal or computer.
