Ports on the CPU364

RS-232, RJ-11 Port (Station Manager Port)

The Station Manager port uses a 6-pin, RJ-11 “phone jack” connector. This port is used to connect a terminal or terminal emulator to access the Station Manager software on the Ethernet Interface. It is also used to connect to the PC Software Loader in case the communications software in the Ethernet Interface needs to be updated. An IC693CBL316 cable (or equivalent) is needed to connect the terminal, emulator, or Software Loader to the Ethernet Interface (see Appendix B, “Communications Ports Characteristics”). On earlier versions of the CPU364 module, this port was labeled “Port 1 RS-232.”

Ethernet Ports

There are two Ethernet ports on the CPU364. Only one port can be used at a time. The Ethernet Interface automatically detects the Ethernet port in use; special configuration is not required.

AAUI (Transceiver) Port

The 14-pin AAUI port provides the electrical and mechanical interface to a user-provided IEEE

802.3transceiver cable, which connects the AAUI Port to an external Ethernet-compatible transceiver (see Appendix B, “Communications Ports Characteristics”, for the characteristics of the AAUI Port and suggested transceivers). The external transceiver is directly connected to the Ethernet cable.

Caution

Do not connect or disconnect a transceiver cable to the AAUI port while power is applied to the PLC. This may blow the AAUI port fuse and/or cause permanent damage to the Ethernet Interface.

10Base-T, RJ-45 Port

This 8-pin, RJ-45 port provides a direct connection to a 10Base-T (twisted pair) Ethernet network without an external transceiver.
