LEDs

Two LEDs allow you to monitor scanner and communication status.

FAULT LED - allows you to monitor scanner status. This LED is red.
The FAULT LED’s normal state is off; therefore, it is off whenever the
scanner is operating properly.

COMM LED - allows you to monitor communication with all
configured devices. This LED is green and its normal state is on once
the processor has entered Run mode. The LED is red if there is a
communication problem. The COMM LED status information is valid
only when the FAULT LED is off.

RIO Link Connector

This 3-pin male connector connects the scanner to the RIO link. The
Allen-Bradley repair part number is 1746-RT29.
