Introduction
Manual Objectives
The purpose of this manual is to provide you with the necessary
information to apply the Serial Communications Module which is available
for products that include the SCANportt communications port. Described
in this manual are methods for installing, configuring, and troubleshooting
the Serial Communications Module.
For information on specific features of Allen-Bradley products mentioned
herein, refer to the product user manual.
Important: Read this manual in its entirety before installing, operating,
servicing, or initializing the Serial Communications Module.
Who Should Use This Manual
This manual is intended for qualified service personnel responsible for
setting up and servicing of these devices. You must have previous
experience with and a basic understanding of communications terminology,
configuration procedures, required equipment, and safety precautions.

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 serial communications module. Failure to comply may result in
personal injury and/or equipment damage.
ATTENTION: This module contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing, or
repairing this assembly. Component damage may result if ESD
control procedures are not followed. If you are not familiar with
static control procedures, reference Allen-Bradley Publication
8000–4.5.2, Guarding Against Electrostatic Damage, or any other
applicable ESD protection handbook.

Chapter Objectives
In this chapter you will learn how to:
Mount the communications module
Configure the communications module
Connect power
Connect SCANport and serial communications cables
Read this chapter completely before you attempt to install or configure
your 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.
Setting Module
Configuration Switches
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).
In all cases, each serial device must have a unique address the target
processor can recognize.
ATTENTION: When you change 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: When you configure the system for the first time,
disconnect the motor from the machine or process during initial
testing.

Cable Requirements
SCANport cables are available in either male–to–male or male–to–female
configuration. Cables (C) of up to 10 meters (33 feet) can be connected
from the master to the SCANport device. If a Port Expander (B1) is used,
subtract the cable length from the master to the Port Expander from the
cable length used to connect the device to the expander
(B1 + C = maximum of 10 meters).

Power Supply Connections
The enclosed communications module is powered from a separate 24V dc
or 115/230V ac power supply (Figure 3.3). With the open-style

Troubleshooting
Chapter Objectives
Use this chapter to help troubleshoot your serial communications system
using the LED indicators on the front of the device (Figure 4.1). The
communications module is a non-serviceable device that should be
returned to Allen-Bradley for replacement when a major fault exists that is
attributable to the communications module itself.

ATTENTION: Servicing energized industrial control equipment
can be hazardous. Electrical shock, burns, or unintentional
actuation of controlled industrial equipment may cause death or
serious injury. Follow the safety-related practices of NFPA 70E,
Electrical Safety for Employee Workplaces, when working on or
near energized equipment. Do not work alone on energized
equipment.
ATTENTION: Do not attempt to defeat or override fault circuits.
The cause of a fault indication must be determined and corrected
before attempting operation. Failure to correct a drive or system
malfunction may result in personal injury and/or equipment
damage due to uncontrolled machine system operation.
