(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 commo n 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.
