3.8.6 P7 Connector—The P7 connector provides for the following
connections:
• Power/ground input for all headphone audio controls and video
controls
• Data bus connections
• Unit ID strapping connections
• Video briefer key input connection
Pins 6,7,9: The unit ID strapping connections provide for
multiple A/V-9691-01(-02)-x units to be installed within the same
data bus system. Up to four (4) A/V-9691-01(-02)-x units may
be installed within the same data bus system using the unit ID
strapping feature.
Pin 10: The video briefer key input will force all 16 video outputs
to one (1) of the eight (8) video source input selections when
activated. The specified video source input to be used for video
briefer selection when activated may be specified during system
configuration.
If no video briefer activation is desired, then the video briefer
key input must simply not be connected when planning for
system design.
The video briefer function is completely separate from the audio
briefer function located on the P12 connector of the A/V-9691-
01(-02)-x.
