Wired Telephone/Satellite Communication Input; Music Input; Receive Activity Indicator (-Rxi); Cockpit Speaker Output (Pac45D 050-045-0006 And Hub45R 050-045-0103 Only ) - PS Engineering PAC45D System Installation And Operation Manual

2.4.8.1 Remote ICS mode control.
When a momentary, normally open, push-button switch is connected between pin P454-18 and
ground, it will change the intercom mode on the Pilot's PAC45D.

2.4.9 Wired Telephone/Satellite Communication input

The PAC45D can accommodate a wired cell phone interface on P454 Pins 17, 26 and 7.
Both Bluetooth and wired Telephone and be accommodated, however, only ONE can be active
at a time.
Low impedance satellite phones might require a tactical radio adapter, PS Engineering P/N
12100.

2.4.10 Music Input

Use the low -level output of any additio nal M usic device to con nect to the au-
dio controller. Maximum signal level is 3 VA C p- p. DO NOT use a speake r -level
outp ut; this will ca use in ternal d amage in th e audio contr oller .
Local oscillators and internal signals from Music equipment can cause undesired interference
with other aircraft systems. Before takeoff, operate the entertainment devices to determine if
there is any adverse effect within the aircraft systems. If any unusual operation is noted in flight,
immediately switch off the entertainment devices.
All additional entertainment devices must be switched off for both takeoff and landing.

2.4.11 Receive Activity Indicator (-RXI)

PAC45D systems have an optional Receive Activity Indicator that flashes the selected receiver
indicator when a signal is present on that receiver. This function is set at the factory at the in-
staller's request, and can only be changed at the factory.
2.4.12 Cockpit Speaker Output (PAC45D 050-045-0006 and HUB45R 050-045-0103
only)
A low-level output is available to drive a separate speaker amplifier (such as PSA210) and con-
tains received audio. This output is P454 Pin 2.

2.5 User Adjustments

The PAC45D is factory set for typical installation. However, several installation adjust-
ments are available. No computer is required.

2.5.1 Unswitched Audio Level
