PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 2.3.3 Trig TY91 mounting requirements The TY91 remote VHF Communications radio is mounted to the aircraft structure with 4 ea #6-32 (not supplied) screws through the mounting flange. Guidance can be found in AC 43.13-2B, Chapter 2. Figure 2-1 TY91 VHF Transceiver (Remote Mount) 2.3.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual imum of ground loop potential. Use only Mil Spec shielded wires (MIL-C-275000, or better). Under no circumstances combine a microphone and headphone wiring into the same shielded bundle. Always use a 2- or 3-conductor, shield wire as shown on the installation-wiring diagram.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 2.5 2.5.1 TY91 VHF COM Interface TY91 Connector (Trig TY91(L) -05 only) The TY91 has a 25-pin crimp type connector.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 2.5.4 Avoid routing the cable round tight bends. Avoid kinking the cable even temporarily during installation. Secure the cable so that it cannot interfere with other systems. TY91 TNC Antenna connection The VHF Com radio uses a solder/crimp TNC connector, Amphenol 31-2. This section describes the technique for attaching the antenna cable to the supplied TNC connector.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual If the simultaneous use of two radio units is required then each antenna should be as far apart as practicable for maximum isolation. We would recommend placing one antenna on top and one on the bottom of the airframe. The Transmit Interlock function should also be used in this case (section 5.6.8).
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual Cellular telephones installed in or carried aboard airplanes, balloons or any other type of aircraft must not be operated while such aircraft are airborne (not touching the ground). When any aircraft leaves the ground, all cellular telephones on board that aircraft must be turned off. The use of cellular telephones while aircraft is on the ground is subject to FAA regulations.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual Table 2-4 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 entertainment inputs.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual Local oscillators and internal signals from entertainment 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.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 2.9 Microphone gain reduction For installations in very noisy aircraft, a reduction in the intercom microphone input gain may be desirable. The PAR200A has two DIP switches located on the main board that can switch the inputs to a lower gain setting. PS Engineering installers call for the Service Aid.
PS Engineering Inc. ® PAR200A Audio Selector Panel, COM radio Controller and Intercom System Installation and Operator’s Manual 2.10 Communications Antenna Installation Notes 2.10.1 Antenna Location For best results while in Split Mode, we recommend that the one VHF communications antenna is located on top of the aircraft while the other communications antenna is installed on the bottom. Any antenna relocation must be accomplished in accordance with AC 43.
