Rmi/Obi - Garmin GIA 63 Installation Manual

4.7.2.7 ILS Energize
Pin Name
ILS ENERGIZE
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

4.8 RMI/OBI

4.8.1 RMI/OBI Function
The MAIN OBI output provides bearing information from the active waypoint based upon GPS
navigation information. The MAIN OBI output may be configured so that it sends VOR/ILS bearing
information when VLOC is selected.
The VOR OBI output provides bearing information from the active waypoint based upon the VOR
receiver.
When a localizer channel is tuned on the VLOC window, there is a bit in the data stream set to indicate
that a localizer frequency is tuned which stows the needle or drives it to the 3 o'clock position.
