Power supplied by serial port/COM port
By default, COM Port 2 does not supply power. It can be set to 5V or +12V power by modifying jumper setting on
Jumper COM2_DCD and COM2_RI on the System Board. Please see table below for setting of these two jumpers. Power
will be available on Pin 1.
[Warning]
If COM Port 2 is set with power, users shall not plug in other devices to that port. Failure to do so may result in
damages on connected devices.
