Serial Ports (COM1, COM2, COM3456)
AIMB-226 supports six serial ports. Rear COM1 supports RS-232 only. Pin header
COM2 supports RS-232 only. Box header COM4~6 supports RS-232; COM4 sup-
ports 5V/12V power and COM3 RS-232/422/485 has auto flow control. These ports
can connect to serial devices, like a thermal printer, or to a communication network.
The IRQ and address ranges for both ports are fixed. However, if you want to disable
the port or change these parameters later, you can do this in the system BIOS setup.
Different devices implement the RS-232 standards in different ways. If you have
problems with a serial device, be sure to check the pin assignments for the connec-
tor.
