This section provides detailed operating instructions for the PS Engineering
PAR200A, Audio Selector Panel/Intercom/VHF Communication Control
Systems. Please read it carefully before using the equipment so that you can
take full advantage of its capabilities.
This section is divided into sections covering the basic operating areas of the
PAR200A systems. They are Communications Transceiver Selection, Audio
Selector, Intercom, VHF COM, entertainment, telephone, and display.
Power and Fail Safe (1)
Unit power is turned on and off by pushing the volume (left) knob. In the
OFF or "EMG" position, the pilot headset is connected directly to Com 1 as
well as unswitched input #1. This allows communication capability regardless of unit condition. Any time power is removed or turned OFF, the audio
selector portion will revert to fail-safe mode.
The power switch controls all audio selector panel functions and the intercom. All pushbutton selections and menu modes (except Bluetooth telephone
association) will be remembered and return to the last state when turned on.
Radio power (as COM 1)
The power supply for the remote communication transceiver is separate from
the audio panel power and control. When the TY91L is installed as COM 1,
it can be controlled separately in the event of a problem in the audio panel
portion, or audio panel power loss.
If the audio panel is turned off by the left knob (or the audio panel breaker is
opened), the display will indicate “Push radio knob within 6 (counts
down) seconds to keep radio on” If the knob is not pushed, the com radio
will also turn off, but if the data knob is pushed within 5 seconds, the radio
frequency display, volume and
frequency control will remain active.

Communications Transmit (XMT) Selection (2)
The two buttons C1 and C2 (# 2) in the XMT section control which communications radio is selected for transmit. The top row of pushbuttons (# 3)
allows selection of the receiver audio. Push the lower button to select the
desired COM transmitter. A green LED above the button illuminates to indicate that the audio is selected.
The PAR200A has an automatic com receiver selector system. Audio from
the selected transceiver is automatically heard in the headsets and speaker (if
selected). You can check this function by switching from Com 1 transmitter
to Com 2 transmitter by pressing the COM 2 transmitter selector pushbutton.
See that the associated Com 2 receive pushbutton indicator light that is located immediately above the Com 2 transmitter pushbutton turns green. This
guarantees that the pilot will always hear the audio from the transceiver selected for transmit.
The PAR200A “remembers” the receiver selection, so that when switching
transmitters from COM 1 to COM 2, if COM 2 audio was previously selected,
COM 1 audio will continue to be heard. This eliminates the pilot having to
switch Com 1 audio back on, after changing transmitters.
When switching from COM 1 to COM 2 while Com 2 was not previously selected, COM 1 audio will be switched off. In essence, switching the mic selector will not override prior selection of COM receiver audio.
Split Mode
The split mode can be activated at any time by pressing the C1 and C2 XMT buttons at the same time.
This places the pilot on COM 1 and the copilot on
COM 2.
Pilot on COM 2 and Copilot on COM 1 is not possible.
In the split mode, the intercom between pilot and
copilot is inhibited to avoid confusion. To restore
intercom if desired, press the “ICS” button.
NOTE
Due to the nature of VHF communications signals, and the size of general
aviation aircraft, it is probable that there will be some bleed-over in the Split
mode, particularly on adjacent frequencies. PS Engineering makes no
guarantee of the suitability of Split Mode in all aircraft conditions.
Swap Mode (Switch from Com 1 to Com 2 remotely)
With an optional yoke mounted, normally open momentary switch, the pilot
can change from the current Com transceiver to the other by depressing this
switch (C1 to C2). To cancel "Swap Mode," the pilot may either press the
yoke mounted switch again, or select a different Com with the XMT buttons.
This does NOT flip-flop the PAR200A Active and Standby frequencies.

COM Audio Selector (3)
Communication audio from the other radio, not selected for transmit, can be
heard by pressing the associated RCV button. You will always hear the audio from the selected transceiver.
In SPLIT mode, only the pilot will hear selected navigation audio (N1 &
N2).
Navaid Audio selection (4)
VHF Navigation receiver audio is selected through two momentary, pushbutton, backlit switches.
The users can identify which receivers are selected by noting which green
LEDs are lit above the button. Navigation aid audio push buttons are labeled
N1 and N2.
Any additional installed receiver audio (Marker,
ADF, etc) is interfaced through an unswitched input.
VHF Transceiver control (5)
The right side of the PAR200A is dedicated to control of the VHF communications transceiver. Frequency selection is always directed to the
STANDBY side of the display.
Frequency Selection (6)
Turn the large (outer) knob to change the frequency whole MHz, and the
smaller, inner knob to change the .100 MHz frequency. It takes two clicks to
change the digit one increment.
Push and release the small knob to transfer standby frequency to the active
frequency.
Click and
release
Radio Volume (7)
The larger outer knob on the left side controls the volume
of the remote TY91L radio.
Radio Squelch
To defeat the radio squelch, push and hold the frequency
knob , until the top of the display changes to ASQ, and release. The display will then switch to ASQ OFF, which defeats the squelch to hear any
weak signals. The next time the small right knob is pushed, the ASQ ON
