NeXGen: Hacking a ID-453/ARN-30 Course Indicator part ii

26 Sep 2019

The last time I blogged about this unit was back in October 2016. So I uncovered it in the "un-move" along with a cable which I had thought was just a spare but nope it belonged to this beast. Basically, it's a Resolver that drives the 'bug' or pointer and 'OBS' there is also a manual control to set the bug on the heading you desire. Currently, the 'bug' is at 0, and the 'OBS' which is the reverse is at 180.

	CPP	Phase Shifter 30 ~	Wires
Type	PS-17-E-1
Stator	2 phase	5 volts	Black & Yellow Purple & Green
Rotor	1 phase	5 volts	White & Red

The following pinout and signal/component information came from TM 11-5826-215-35 figure 76.1.
