Chapter 2: Motherboard information
NOTES:
• N5105I-IM-A R2.0 supports six serial ports. COM1 supports RS-
232/422/485 and COM2~6 are RS-232. COM4~6 also supports
Ring/5V/12V according to jumper selection. You can select among RS-
232/422/485 mode, and select the RI voltage among Ring/5V/12V from
BIOS settings for COM1 port.
• You can connect serial devices such as a mouse, a printer or a
communications network device to the COM ports. The IRQ and address
ranges for all the ports are xed. However, you 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.
• If problem with a serial device occurs, it is recommended that you check
the connector pin assignments.
• The serial port cable is purchased separately.
24. COM Port headers (10-pin COM4~COM6)
These headers are for serial (COM) ports. Connect the serial port cables to
these headers, then install the module to a slot opening at the back of the
system chassis.
