The serial ports are asynchronous communication ports with 16C550A-compatible UARTs that
can be used with modems, serial printers, remote display terminals, and other serial devices.
COM 1 supports three serial modes, i.e. RS232, RS422, and RS485 as well as RS232 with/with-
out power.
Jumper Setting
Serial mode and RS232 with/without power of COM 1 are configured via jumper settings as
previously instructed in this chapter.
BIOS Setting
Configure the onboard COM ports in the Advanced menu (“Console Redirection” and "SIO NU-
VOTON6116D" submenus) of the BIOS. Refer to chapter 3 for more information.

COM 1 and 2 support three serial modes, i.e. RS232, RS422, and RS485. COM 3 and 4 only sup-
port RS232.

The USB device allows data exchange between your computer and a wide range of simultane-
ously accessible external Plug and Play peripherals.
In addition to the rear USB ports as introduced previously in this chapter, the system board
is equipped with four internal USB 2.0 ports (two pin headers) and 2 USB 3.1 Gen2 ports as
illustrated above. The pin headers for USB 9/10 can also be replaced by a Type A vertical con-
nector.
The internal USB pin headers may be connected to a card-edge bracket. Install the card-edge
bracket to an available slot at the rear of the system chassis and then insert the USB port
cables to a connector.
Wake-On-USB Keyboard/Mouse
The Wake-On-USB Keyboard/Mouse function allows you to use a USB keyboard or USB mouse
to wake up a system from the S state(s).
