Summary of Changes
The information below summarizes the changes made to this manual
since the last release.
Updated Information
This manual incorporates the information found in the following two
manuals:
•Bulletin 1203 Remote I/O Communication Module Getting
Started Manual, Publication 1203-5.1.
•Bulletin 1203 Remote I/O Communications Module Reference
Manual, Publication 1203-5.0.
It also contains new information.
Updates and Additions
The information below summarizes the changes to this manual since
its last release:
Page Description
2-5 Important statement added:
Injury or equipment damage can result from loss of PLC or Controller Logic
Commands (Stop, Start, etc.) when all these conditions are true:
- module firmware 3.04 or lower.
- 230.4k baud rate.
- block transfer is enabled (DIP switch SW3-1 is ON).
- block transfers to the module are used (in the ladder program or by DriveTools/
DriveTools32 using a Remote I/O pass thru connection).
Do not use the 230.4k baud rate if you are using a module with 3.04 or earlier
firmware and your program uses block transfers. Use the 57.6k or 115.2k baud
rate instead.
2-6 Attention statement added:
Due to an anomaly in firmware release 4.01, Remote I/O modules that are used
only for block transfer messages require the following configuration: switches for
block transfer and reference/feedback should both be enabled (SW 3.1 and SW
3.3 are ON. SW 3.2 and SW 3.4 through 3.8 are OFF).
This configuration prevents a fault on power up. It does not affect rack I/O
allocation or the ladder logic program because it still fits within 1/4 rack I/O space.
The drive will, however, generate a serial fault if the communications module is
disconnected or loses power.

configuration procedures, required equipment, and safety precautions.
To use this Remote I/O communications module efficiently, you must
be able to program and operate programmable controllers as well as
have a basic understanding of the parameter settings and functions of
the SCANport™ product with which you are communicating.
Purpose of This Manual
This manual is an installation and user guide for the Remote I/O
communications module. The 1203 Remote I/O communications
modules are available for products that include SCANport.
This manual provides the following information:
• An overview of the Remote I/O communications module.
• Procedures that you need to install, configure, and troubleshoot
the Remote I/O communications module.
• Example ladder logic programs for controlling a product and
using block transfer messages.
Important:
You should read this manual in its entirety before
configuring, installing, operating, or troubleshooting the
Remote I/O communications module.
Firmware Support
This manual supports firmware versions 1.xx to 4.xx (the “xx”
designator may vary). Features that work with specific firmware
versions will be identified.

Terms Definition
Controller A solid-state control system that has a user-programmable memory for
storage of instructions to implement specific functions such
as I/O control, logic, timing, counting, report generation, communica-
tion, arithmetic, and data file manipulation. A controller is also called a
“programmable logic controller” or “processor.”
Remote I/O I/O connected to a processor across a serial link. With a serial link,
remote I/O can be located long distances from the processor.
Remote I/O
Communications
Module
This module connects a SCANport product to a Remote I/O link. There
are three types of Remote I/O communications modules: 1203-GD1
module, 1203-GK1 module, and 1336-GM1 board. The Remote I/O
module is also referred to as “adapter,” “module,” and communications
module.”
SCANport A standard peripheral communications interface for various
Allen-Bradley drives and power products.
SCANport
Peripheral
A device that provides an interface between SCANport and a commu-
nications system such as Remote I/O. It is often referred to as an
adapter or communications module. For example, the Remote I/O
module is a SCANport peripheral.
SCANport
Product
A device that uses the SCANport communications interface to commu-
nicate with one or more peripheral devices. For example, a motor drive
such as a 1336 PLUS is a SCANport product.

Using This Manual P–3
Safety Precautions
!ATTENTION: Only personnel familiar with SCANport
devices and associated machinery should plan or implement
the installation, start-up, configuration, and subsequent
maintenance of the Remote I/O communications module.
Failure to comply may result in personal injury and/or
equipment damage.
!ATTENTION: The 1336-GM1 board contains Electrostat-
ic Discharge (ESD) sensitive parts and assemblies. Static
control precautions are required when handling this assem-
bly. Component damage may result if ESD control proce-
dures are not followed. If you are not familiar with static
control procedures, refer to Allen-Bradley Publication
8000-4.5.2, Guarding Against Electrostatic Damage or any
other applicable ESD protection handbook.
!ATTENTION: Injury or equipment damage can result
from loss of PLC or Controller Logic Commands (Stop,
Start, etc.) when all these conditions are true:
• module firmware 3.04 or lower.
• 230.4k baud rate.
• block transfer is enabled (DIP switch SW3-1 is ON).
• block transfers to the module are used (in the ladder
program or by DriveTools/DriveTools32 using a
Remote I/O pass thru connection).
Do not use the 230.4k baud rate if you are using a module
with 3.04 or earlier firmware and your program uses block
transfers. Use the 57.6k or 115.2k baud rate instead.
!ATTENTION: Hazard of equipment damage exists. If
block transfer messages are programmed to frequently
write parameter data, the EEPROM (Non-Volatile Storage)
will quickly exceed its life cycle and cause the product to
malfunction. Do not create a program that frequently uses
block transfer messages to write parameter data to a
product. Datalinks do not write to the EEPROM and should
be used for frequently changed parameters.
!ATTENTION: Hazard of equipment damage exits.
Firmware version 3.04 has the following anomaly: If DIP
Switch 2-5 is OFF (No Fault), the product remains in its last
state after a communications loss occurs no matter how DIP
Switch 2-4 is set. If you must use zero data, contact
Rockwell Automation Technical Support.
