SPDIF_In/ SPDIF_Out Headers
The SPDIF_In (JSPDIF_In) and SPDIF_Out (JSPDIF_Out) headers are located next to PCI-E
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.
TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM)/Port 80, which is
available from a third-party vendor. A TPM/Port 80 connector is a security device that supports
encryption and authentication in hard drives. It allows the motherboard to deny access if the
TPM associated with the hard drive is not installed in the system. See the table below for
pin definitions.
Disk-On-Module Power Connector
The Disk-On-Module (DOM) power connectors at JSD1 and JSD2 provide 5V power to
solid-state DOM storage devices connected to the SATA ports. See the table below for pin
definitions.
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.
