ACRCOMM Overview

The ACRCOMM Plug-In Module provides serial communication ports (2 serial, 1 parallel) capability for the ACR1505 motherboard. ACRCOMM external power input and User-SRAM battery back-up functions are not used with the ACR1505 motherboard. These circuits are not populated on the ACR1505 COMM Board.

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

Serial Communications

The ACR1505 serial communication interface is software configurable. At power-up, the default COM1/COM2 communications mode is RS-232. For ACR1505 boards with the communications option, the serial ports can be configured by a serial port, or at power-up (or any time) via the PCI bus communications port.

Table 1 and Table 2 show the configuration schemes for the ACR1505 board with the serial communication ACRCOMM module option.
