Serial Ports (COM1 ~ COM6)

AIMB-215 B1 supports six serial ports. COM3 is RS-232/422/485 and COM1/2/4/5/6
are RS-232. COM6 also supports 5 V/12 V according to jumper selection. Users can
employ JSETCOM3 to select between the RS-232/422/485 modes for COM3. Such
ports can be connected to serial devices, such as a mouse or printer, or to a commu-
nications network.
The IRQ and address ranges for both ports are fixed. However, users can disable the
port or change the parameters via the system BIOS setup.
Various devices implement the RS-232/422/485 standards in different manners.
Users who experience problems with a serial device are advised check the connector
pin assignments.
