DESCRIPTION

The following is a description of the faceplate LEDs, field termination

connectors, and electrical characteristics of the field connections.

2.1 Mechanical Description

The Processor module is a printed circuit board assembly that plugs

into the backplane of the DCS 5000/AutoMax rack. It consists of the

printed circuit board, a faceplate, and a protective enclosure. The

faceplate contains tabs at the top and bottom to simplify removing

the module from the rack. On the back of the module are two edge

connectors that connect to the system backplane. Module

dimensions are listed in Appendix A.

The faceplate of the Processor module contains two

independentlyĆisolated 25Ćpin D" shell connectors for RSĆ232C serial

I/O links. The upper port (labeled PROGRAMMER/PORT B") of the

leftmost Processor in the rack is reserved for connection to the

personal computer only. The personal computer can communicate

with all Processors in the rack through this connection.

All remaining Processor module ports (both those labeled

PROGRAMMER/PORT B" and PORT A") are available for use by

application tasks running on the respective Processors. Refer to

figure 2.1 for the Processor module faceplate and Appendix C for a

pin description.
