(1) Functional Description and Operation
Communication with Mode S transponders is accomplished through an ARINC
429 bus as defined in ARINC Characteristic 718. Control panel functions include
4096 ident code selection and display, altitude source and reporting inhibit
selection, selection between two onboard transponders, TCAS TA or TA/RA
advisory selection, range selection (in nautical miles) and a system functional
test selection. A description of the front panel annunciator and switch functions
follows.
(a) Transponder Code Display
The control panel has a single four digit LCD display common to both
modules within the unit. The display shows the ATC code selected by the
user and consequently transmitted to the transponders. Input to the
display is controlled by the system select switch (XPDR 1-2).
In addition, certain fault indications are also indicated on the display.
After a functional test has been initiated, PASS shows on the display
after a successful test, or it shows FAIL if a high level failure is detected
under normal operating conditions. It also shows which transponder is
active by displaying ATC 1 or 2.
(b) ATC Code Selection
The ATC four-digit code is selected with two dual concentric sets of
knobs. Each knob is dedicated to a single liquid crystal display (LCD)
digit on the LCD code display. The two smaller knobs control the inner
digits of the LCD (tens and hundreds) while the two larger knobs control
the outer most digits (units and thousands).
(c) XPDR 1-2 Switch
The XPDR switch is a two position switch that allows the selection of one
Mode S module in the control panel, and the activation of its associated
transponder (System 1 or System 2).
