AIMB-225 User Manual 22
2.4 Serial Ports (COM1, COM2345)
AIMB-225 supports five serial ports. Box header COM1 support RS-232/422/485
auto flow control function. Pin header COM2~5 support RS-232 and COM5 support
5V/12V by jumper selection. 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 connector.
