If an external dimmer control is not used, a constant back light illumination can be established for night-

time viewing. Pin 6 or 7 (depending on system voltage) must be tied to power (J2, pin 8 or 9) for the back

lighting system to work. The photocell mounted in the unit face will automatically adjust the intensity of

the push-button annunciation green LEDs.

2.6.5 Unswitched inputs

J1, pins 31, 29 and J2 pin 15 are unswitched, unmuted (by transmitter keying), inputs # 1, 3 and 4, re-

spectively. These inputs are presented to the pilot and copilot regardless of the audio configuration, and

will mute the entertainment inputs based on the mode. These 510 Ω inputs can be used for altimeter DH

audio, GPS waypoint audio, autopilot disconnect tones, or any other critical audio signal. Unswitched #1

is always presented to the crew headphones, and is available to the pilot in fail-safe (off) mode.

Table 2-5 Unswitched input table

J1, pins 31, 29 and J2 pin 15 are unswitched, unmuted inputs # 1, 3 and 4, respectively. These inputs are

presented to the pilot and copilot regardless of the audio configuration, and will always mute the enter-

tainment inputs. These 510Ω inputs can be used for altimeter DH audio, GPS waypoint audio, autopilot

disconnect tones, or any other critical audio signal.

The audio low for unswitched #4 (J2, pin 15) should be connected to a convenient audio low. However,

this should NOT be connected to Music Low.

Unswitched #1 is presented to the pilot headphone in fail-safe (off) mode.

NOTE

Inputs 1, 2 and 4 are fixed (1:1), and any audio level adjustments must be made at the input source. Unswitched #3

has a variable adjustment control located on the bottom side of the unit. This control allows you to control the volume

level of that unswitched input from 50% to 200% of the input level. Refer to Adjustments section.

2.7 Intercom wiring

See Appendix C and D for intercom connection configurations. It is critical to the proper operation of this

system to have this connector wiring made in accordance with these diagrams. Use 2- and 3-conductor,

MIL-spec cable as shown. Connect the shields at the audio panel end only, and tie to the audio low inputs

as shown.

NOTE

The system harness can be custom made by PS Engineering, Inc. Simply call the factory or www.ps-

engineering.com to obtain a wire harness work sheet. The harness will be made to your specifications and

fully functionally tested. Harness can be ordered with jack, or without the intercom jacks installed, for

easier wire routing through the aircraft.

2.7.1 Music Inputs

The PAR200 has two INDEPENDENT inputs wired into the rear connectors, in addition to the Blue-

tooth® music streaming (which is presented as Music 1). Music input number 1 is J2 pins 23 (left chan-

nel) and 24 (right channel), with respect to pin 25, and Music number 2 is connected to 26 (left channel),

27 (right channel), with respect to 28.

Music #1 is available to the pilot and copilot positions, only, in normal configuration. Music 1 can be hear

by all aircraft occupants, if Music 1 all headsets is activated. See §2.7.1.1
