Shield Ground
For connection to external floating
shields
PAX Headset lines from the same GROUP may be connected in parallel to give more drive for a rear
headset bus, but then must have isolation safety resistors installed (~47-51ohms) in series with the
rear headsets for accidental short circuit isolation. See installation drawings for full details.
The Pin 2/10 Direct Input is connected directly to the pilot’s H/S via a resistive pad, if multiple units use
this connection to a common source, massive cross-talk will result. Connect ONLY ONE station in this
way to a single external source
Common Lines
Floating above airframe ground in ACCESS systems, but serves as
common signal low for corresponding output signal lines only.
Common Lines
At Ground potential, but line must be connected here only, not to
airframe.
