Serial Ports (COM1~COM10)
AIMB-503 supports ten serial ports. COM1. COM2. COM4-6. COM8-10 supports RS-
232. COM3 & COM7 supports RS-232/422/485 (supports RS-485 auto flow control).
JSETCOM3 & JSETCOM7 is used to select the RS-232/422/485 mode for COM3 &
COM7. COM1 & COM2 is with selectable 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.
