Serial Port
There is a COM header (COM2) on the motherboard. The COM port and header provide
serial communication support. See the table below for pin definitions.
SPDIF_In/ SPDIF_Out Headers
The SPDIF_In (JSPDIF_In) and SPDIF_Out (JSPDIF_Out) headers are located next to PCIe
Slot 5 on the motherboard. Place a cap on each header for audio support. You will also need
to have a cable to use each connection.
