Installing the IC697CMM742 Ethernet Interface
The IC697CMM742 Ethernet Interface is mounted in a Series 90-70 PLC rack. It is connected to
an Ethernet network via a 10Base-T port, a 10Base2 port, or a user-provided transceiver cable and
transceiver via an AUI port.

LABEL
The CMM742 has several user-accessible elements.
Four LEDs are located at the top of the board. The Restart pushbutton is located immediately
below the LEDs. The RS-232 serial port with the RJ-11 connector (similar to a modular
telephone connector) is the Station Manager port. The RS-485 serial port with the 15-pin “D”
connector located immediately below the Station Manager port is the module’s Software Loader
port. Below these there are three ports, any one of which can be used to connect to the Ethernet
network: the 10Base-T, RJ-45 port, the AUI port, and the 10Base2, BNC port.
LEDs
There are four LEDs on the Ethernet Interface: MODULE OK, LAN ONLINE, SERIAL
ACTIVE, and STATUS. Each of these LEDs can be ON, OFF, BLINKING slow, or BLINKING
fast. They indicate the state of the Interface, traffic on the network port (LAN ONLINE LED),
and that an exception event has occurred.
