Functional Description
J1/J2--22, 23 ARINC 429 OUTPUTS: (J1/J2--22,23)
Communication between the control panel and the transponder is done over a two wire
low speed, odd parity, ARINC 429 compatible bus. Selected ATC code, operating mode,
and system parameters are communicated to the transponder over these lines.
T ransmission of labels 013, 015, 016, and 031 is done every 150 milliseconds.
Connect these pins to one of the two transponder ARINC 429 CONTROL DAT A Input
Ports.
J1/J2--24 AIR/GROUND INPUT DISCRETE: (J1/J2--24)
The control panel accepts input from two independent Air/Ground (WOW) switches for
applications that require automatic disabling of the transponder upon landing. This input
is wired directly to the AIR/GROUND SW Discrete Output (J1/J2--15).
