CHARACTERISTICS
POWER ±12VDC ±5% regulated, less than 100mA. Power
output from the display/processor to the antenna. It is
used to power the active circuitry inside the antenna.
CONNECTION J1-11 (-12V) to NY163, Pin F
X-LOOP Signal provided by the X-Loop winding within the
antenna. Bipolar signal voltage, ±11 V Peak Max., .1
V Peak @ 200nmi WX-PA Simulation Standard ±20%,
20 Ohm output impedance, single ended. Loop current
to GND, less than 60µA.
CONNECTION J1-24 (X LOOP) to NY163, Pin C
Y-LOOP Signal provided by the Y-Loop winding within the
antenna. Bipolar signal voltage, ±11 V Peak Max., .1
V Peak @ 200nmi WX-PA Simulation Standard ±20%,
20 Ohm output impedance, single ended. Loop current
to GND, less than 60µA.
CONNECTION J1-25 (Y LOOP) to NY163, Pin G
These connections from the aircraft heading source (ARINC Synchro Signal
Practices) allow the unit to rotate the displayed storm data as the aircraft
turns.
Synchro heading input is selected via the SYNC jumper located in
the connector back-shell.
