Wake-On-PS/2 Keyboard/Mouse
The Wake-On-PS/2 Keyboard/Mouse function allows you to use the PS/2 keyboard or PS/2
mouse to power-on the system. To use this function:
Jumper Setting: JP2 must be set to “2-3 On: 5VSB”. Refer to “PS/2 Power Select” in
this chapter for more information.
BIOS Setting: Configure the PS/2 wake up function in the Integrated Peripherals
submenu (“Onboard Super IO Device” section) of the BIOS. Refer to chapter 3 for
more information.
Important:
The 5VSB power source of your power supply must support
≥
720mA.
2.5.2 Serial
Ports
The system board is equipped with two onboard serial ports at locations CN13 (COM 1) and
CN14 (COM 2). It is also equipped with two 9-pin connectors at locations J14 (COM 3) and J15
(COM 4). These serial ports are RS-232 and/or RS-485 asynchronous communication ports with
16C550A-compatible UARTs that can be used with modems, serial printers, remote display
terminals, and other serial devices.
To connect COM 3 and/or COM 4, 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 J15. Make sure the colored stripe on the ribbon cable is aligned
with pin 1 of J14 or J15.
Important:
If the LCD Display Panel that is connected to the LVDS LCD Panel connector supports touch
screen, DO NOT connect a serial device to COM 3 because the touch screen function is internally
connected to COM 3.
Jumper Setting
If the serial device connected to COM 2 and/or COM 4 requires auxiliary power from the
system board, set JP6 and/or JP9 appropriately. Refer to “COM 2’s RS232/AUX Select” and “COM
4’s RS232/RS485/AUX Select” in this chapter for more information.
