CHAPTER 2 OVERVIEW

The ACRCOMM Plug-In Module provides stand-alone operation capability for the
ACR2000 motherboard. ACRCOMM functions include external power input, User-
SRAM battery back-up capability, and communication ports (2 serial, 1 parallel).

This section contains diagrams of the jumpers and switches on the ACRCOMM module.

Factory default jumper settings for the ACRCOMM module are highlighted within the
following jumper tables.
