(5) RS-232 Connector (CN7 & DB2)

There are two serial ports with EIA RS-232 interface on the AR-B1375 or AR-B1376. COM A uses one on-board
D-type 9-pin male connector (DB2) which is located at the right side of the card, and COM B uses one 10-pin
header (CN7) which is located at the upper of the card. To configure these two serial ports, use the BIOS Setup
program to do well, and adjust the jumpers on J6 and J7.
The pin assignments of the DB2 and CN7 for serial port A & B are as follows:
