GE IC693CMM321 Ethernet Interface Module Board Indicators

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 is the Station Manager port.

The RS-485 serial port with the 15-pin D connector located below the Station Manager port is the

module’s Downloader port.  The 14-pin AAUI connector, facing downward, is the Transceiver

port.  The Default MAC Address label is attached to the outside of the plastic housing.

Board Indicators

There are four LEDs on the Ethernet Interface:  OK, LAN, SER, and STAT.  These LEDs can be

ON, OFF, BLINKING slow, or BLINKING fast.  They indicate the state the Interface is in, traffic

on the Transceiver port and Downloader port, and when an exception event has occurred.

Restart Button

The Restart button serves four functions:  LED test, Restart, Restart and Reload, and Restart and

Enter Maintenance Utility.  The Restart button is inaccessible when the front cover of the Ethernet

Interface is closed.

Serial Ports

There are two serial ports on the Ethernet Interface:  the Station Manager Port and the Downloader Port.

The Station Manager Port.  This RS-232 port is used to connect a terminal or terminal emulator

to access the Station Manager software on the Ethernet Interface.  This port uses a  6-pin, RJ-11

connector.  The IC693CBL316 Station Manager cable is ideal for connecting to this port .

The Firmware Upgrade Port.  The 15-pin, D-type, RS-485 port is used to connect to the PC

Downloader in case the communications software in the Ethernet Interface needs to be updated.

Use the IC690ACC901 miniconverter/cable kit for this connection.
