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 SCANport 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: This manual should be read 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.

To make efficient use of this Communications Module, you must be able to

program and operate serial communications devices, as well as have a

basic understanding of the parameter settings and functions of the device to

which you are communicating.

Vocabulary In this manual we refer to the:

Serial Communications Module as “Communications Module.”

Variable Frequency AC Drive (Bulletin 1305, 1336 FORCE, or 

1336 PLUS) as the “Drive” or “SCANport device”.

Programmable Logic Controller as the “Programmable Controller” or

“PLC”.

Earth Ground as “GND”.

Firmware Support This manual supports communications module firmware versions 1.xx (the

“xx” designator may vary). Features that work with specific firmware

versions will be denoted as such.

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.

Product Description Chapter Objectives In this chapter, you will read about:
Communications Module features
Location of configuration switches Module Description 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, and SMP3 controllers. The module connects to these products through the SCANport port. The Communications Module is available in both Open style (Figure 2.1) and Enclosed (Figure 2.2) type configurations. The Open style module mounts inside certain drives, depending on drive size (see Table 2.A for details). The Enclosed module mounts independently and can be used with any compatible SCANport device.

Installation 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 selections are changed after power is applied, cycle the power to use the new settings. Setting Module This publication describes switches as being either on or off. If the switch Configuration Switches assembly has the word OPEN printed on it, the word OPEN corresponds to OFF (0). When making configuration changes to the 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 the target processor can recognize.

Switch SW1 Switch SW1 is used to select:
Serial communications mode (RS232/RS422/RS485)
Communications Module address
