Solid state equipment has operational characteristics differing from
those of electromechanical equipment. “Safety Guidelines for the
Application, Installation and Maintenance of Solid State Controls”
(Publication SGI-1.1) describes some important differences between
solid state equipment and hard–wired electromechanical devices.
Because of this difference, and also because of the wide variety of
uses for solid state equipment, all persons responsible for applying
this equipment must satisfy themselves that each intended
application of this equipment is acceptable.
In no event will the Allen-Bradley Company be responsible or liable
for indirect or consequential damages resulting from the use or
application of this equipment.
The examples and diagrams in this manual are included solely for
illustrative purposes. Because of the many variables and
requirements associated with any particular installation, the
Allen-Bradley Company cannot assume responsibility or liability for
actual use based on the examples and diagrams.
No patent liability is assumed by Allen-Bradley Company with
respect to use of information, circuits, equipment, or software
described in this manual.
Reproduction of the contents of this manual, in whole or in part,
without written permission of the Allen-Bradley Company is
prohibited.
Throughout this manual we use notes to make you aware of safety
considerations.
!ATTENTION: Identifies information about practices
or circumstances that can lead to personal injury or
death, property damage, or economic loss.
Attentions help you:
•identify a hazard
•avoid the hazard
•recognize the consequences

Product Description
In this chapter, you will read about:
•Serial Communications Module features
•the location of configuration switches
The Serial Communications Module is an optional interface device
designed to provide a direct digital link between serial
communications devices and any device that uses SCANport. The
current list of products that use SCANport includes: 1305, 1336
PLUS, 1336 FORCE, 1394, SMP3 controllers, and 1557 medium
voltage drives. The module connects to these products via
SCANport.
The Serial Communications Module 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. The Enclosed module mounts independently and can be used
with any SCANport device. The following table provides more
information about the Open and Enclosed styles.

Installation
In this chapter, you will learn how to:
•set the module configuration switches
•mount the Serial Communications Module
•connect the cables
•connect the SCANport link
•connect the power supply
Read this chapter completely before you attempt to install or
configure your Serial Communications Module. Double check all
connections and option selections before you apply power.
Important: Switch selections take effect only on power–up. If you
change selections after power is applied, cycle the
power to use the new settings.
When making configuration changes to the Serial Communications
Module, use the addressing conventions of the PLC/SLC processor
or serial device through which you are communicating. In all cases,
each serial device must have a unique address that the target
processor can recognize.
!ATTENTION: When changing the switch settings,
use a blunt, pointed instrument such as a ball point pen.
Do not use a pencil because the lead (graphite) of the
pencil may damage the switch assembly.
!ATTENTION: Failure to check connections and
switch settings for compatibility with your application
when configuring the communications module could
result in personal injury and/or equipment damage due
to unintended or undesirable operation.
!ATTENTION: It is recommended that when a system
is configured for the first time, you should disconnect
the motor from the machine or process during the
initial testing.
This publication describes switches as being either on or off. If the
switch assembly has the word OPEN printed on it, the word OPEN
corresponds to OFF (0).
If a switch is shown as gray, then that switch does not affect the
function being covered.
