21) Digital Audio Interfaces (2-pin SPDIFOUT/CDSPDIFIN) (optional)

22) Chassis Open Alarm Lead (4-pin CHASSIS)

This lead is for a chassis designed for chassis intrusion detection. This requires
an external detection mechanism such as a chassis intrusion monitor/sensor or
microswitch. When any chassis component is removed, the sensor is triggered
and a high-level signal is sent to this lead to record a chassis intrusion event.The
event is then be processed by software such as LDCM. When not using the
chassis intrusion lead, place a jumper cap over the pins to close the circuit.
