Publication 1203–5.1 –– July, 1997
Overview
Chapter 1 covers the following information:
• a description of the communications module
• SCANport device compatibility
• configuration switches
• datalinks
• safety precautions
The remote I/O communications module is an optional interface
device designed to provide a direct, digital link between an
Allen-Bradley programmable controller and any device that uses the
SCANportt communication port. The current list of products that
use the SCANport communications interface includes: 1305, 1336
PLUS, 1336 FORCE, 1336 IMPACT, 1397, and SMP3 and SMC
Dialog Plus. The board connects to these products through the
SCANport peripheral interface.
The adapter is available in both Open style (Figure 1.1) and Enclosed
(Figure 1.2) type configurations. The Open style module mounts
inside certain drives, depending on drive size (refer to Table 1.A).
You can use the Enclosed module with any compatible SCANport
device that is mounted outside the drive package.

The remote I/O communications module does not support version
1.xx (the .xx designator may vary) of the 1305 drive. If you try to
use the remote I/O communications module with a version 1.xx
1305, the remote I/O communications module will continually reset
itself, resulting in the red adapter fault status LED and the amber
SCANport status LED both flashing simultaneously indicating an
error condition. Firmware revision 2.xx or higher on the 1305 is
required to support remote I/O communications and block transfer.
