1. All shields should be grounded at audio panel only.
other end remains floating.
2. Speaker and Pilot Headphone ground returns
MUST be kept separate and connected
to pin 22.
3. All Power and Ground wires must be #18 gage wire
4. Pilot mic and headphone jacks must be isolated from ground.
5. PA Mute is a TTL level logic output
that is pulled low when PTT active.
6. Speaker loads may be reqired on some transceivers.
Consult manufacturer's information.
7. 28V installations require 15 ohm, 15W dropping
resistor.
8. All shielded wires must be MIL 22750 or 27500.
9. For mono versions (PMA6000, PMA6000M)
connect pilot headphone to pin 3 with 2-conductor wire.
For stereo versions (PMA6000S and PMA6000M-S) connect
pilot headphone (L) to top connector, Pin 1,
using 3-conductor wire.
10. Key pin between pin 7 and 8.
11. For PMA6000 without marker, marker audio can be
interfaced through pin 11 (aux), and will
appear when M button pushed.
12. Marker Lamp outputs (C, 5, 4) go to +9 VDC, +/- 2VDC
at maximum bright, unlaoded) when active.
