Serial Ports (COM1~COM6)

AIMB-502 supports six serial ports. COM1 supports RS-485 and 6 bit non-progam-
mable GPIO (4 in, 2 out) and COM2 - 6 support RS-232. COM 5, 6 support 5V/12V
power (JSETCOM5_V1, JSETCOM6_V1 is used to select for 5V/12V power).
These ports can connect to serial devices, such as a mouse or a printer, or to a com-
munications 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.
