G4H875-N only

G4H875-N is equipped with 2 onboard serial ports (COM 1: CN3 and COM 2: CN4) - both in Teal/Turquoise color. It is also equipped with two 9-pin connectors (COM 3: J14 and COM 4: J16) for connecting external serial ports.

G4H875-C and G4H875-B are each equipped with COM 1 (CN3) and COM 2 (CN4). COM 3 and COM 4 are not present on these boards.

To use J14 or J16 to connect external serial ports, please refer to the following description. The serial ports may be mounted on a card-edge bracket. Install the card-edge bracket to the system chassis then insert the cable connector to J14 or J16. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of J14 or J16.

Serial ports are RS-232C asynchronous communication ports with 16C550A-compatible UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices.

BIOS Setting

Select the serial ports’ I/O address in the Integrated Peripherals submenu (“Super IO Device” section) of the BIOS. Refer to chapter 3 for more information.
