Dme Tuning And Adf - Garmin GIA 63W Installation Manual

4.9 DME Tuning and ADF

4.9.1 DME Tuning Function
The GIA 63(W) can channel a DME based on the tuned VLOC frequency. The GIA 63(W) outputs 2 of
5, BCD or Slip parallel DME and King Serial DME channeling format. When DME COMMON is held
low, the GIA 63(W) actively tunes the DME.

NAV DME COMMON
For each of the parallel DME tuning discrete outputs:
INACTIVE: Floating (can be pulled up to externally sourced Vout in the range 0 ≤  V out ≤  3 3VDC)
Leakage current in the INACTIVE state is typically ≤ 10 uA to ground
ACTIVE: Vout ≤ 0.5VDC with ≤  2 0 mA sink current
Sink current must be externally limited to 20 mA max
NAV DME COMMON must be pulled low to indicate to the NAV module that it is the device channeling
the DME.
INACTIVE: 10 ≤  V in ≤  3 3VDC or Rin ≥ 100kΩ
ACTIVE: Vin ≤ 1.9VDC with ≥  7 5 uA sink current, or Rin ≤ 375Ω
Sink current is internally limited to 200 uA max for a grounded input
