Baud Rate Dip Switch; Leds; Rio Link Connector - Allen-Bradley 1747-SN User Manual

Baud Rate DIP Switch

The Baud Rate DIP switch selects the RIO link baud rate. The baud
rates are:
57.6 Kbaud
115.2 Kbaud
230.4 Kbaud
Important:
For proper system operation, the baud rate of all devices
on the RIO link must be the same.

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.
