1-22 Chapter 1: Product Introduction
9. Chassis intrusion connector (4-1 pin CHASSIS)
This lead is for a chassis designed with intrusion detection feature. This
requires an external detection mechanism such as a chassis intrusion sensor
or microswitch. When you remove any chassis component, the sensor
triggers and sends a high-level signal to this lead to record a chassis intrusion
event.
By default, the pins labeled “Chassis Signal” and “Ground” are shorted with a
jumper cap. If you wish to use the chassis intrusion detection feature, remove
the jumper cap from the pins.
10. Digital audio connector (3- pin SPDIF)
This connector is for the S/PDIF audio module that allows digital sound input.
• Use 75 ohm impedance matched coaxial cables for your S/PDIF connection.
• The S/PDIF module is purchased separately.
