9 COM Ports
The system has three COM ports for communicating with external devices. COM1, COM2
and COM3 ports are located on the rear panel via 9-pin D-Sub male connectors. They are
implemented using industrial-grade ITE8786 Super IO chip (-40 to 85°C) and provide up to
115200 bps baud rate.
COM1 and COM3 are software-configurable RS-232/422/485 ports and COM2 is a standard
9-wire RS-232 port. The operation mode, slew rate and termination of COM1 and COM3 can
be set in BIOS setup utility. The following table describes the pin definition of COM ports.

10 USB2.0 Ports
The USB2.0 ports are implemented via native xHCI (eXtensible Host Controller Interface)
controller in Q170 chipset and are backward compatible with USB 1.1 and USB 1.0 de-
vices. Legacy USB support is also provided so you can use USB keyboard/mouse in DOS
environment.
11. 3-Pin Terminal Block for DC and Ignition Input
The system allows an 8 to 35V DC power input from via a 3-pin pluggable terminal block.
The screw clamping mechanism is a reliable way to wire DC power.
In addition to DC power, this terminal block also accepts ignition signal input (IGN).
WARNING
Please make sure the voltage of DC power is correct before you connect it to the
system. Supplying a voltage over 35V will damage the system.
