RMI and ADF conversion functions

The source description states that the KDA 692 works with the KR 87 ADF and KNS 81 navigation system. It converts serial BCD RMI angle information from the KNS 81 to a four-wire AC sine/cosine format. It also converts compatible DC sine/cosine ADF bearing information from the KR 87 into a three-wire synchro angle output. These conversions allow approved indicators or downstream avionics to receive bearing data in the signal format required by the aircraft installation.

The practical signal path is therefore source equipment to KDA 692 conversion and then to the compatible indication circuit. The adapter cannot create valid bearing information when the connected receiver, navigation unit, antenna, wiring, reference supply or indicator is defective. Fault isolation should follow the approved aircraft wiring diagram and BendixKing maintenance procedures rather than treating 071-1217-01 as an isolated consumer device.

Electrical data and installation

The photographed identification plate marks a 28 VAC, 400 Hz supply and a 20 VA rating. It also shows a weight of 1.9 lb and TSO C52a with a DO-160 environmental reference. These values belong to the photographed 071-1217-01 unit and are included as identification data; the final installation must still be checked against the applicable equipment manual and aircraft approval package.

Installation requires the correct mounting location, connector, pin assignment, power protection, 400 Hz reference supply, signal wiring and grounding. Cable shielding and routing are important for low-level bearing information. A rack, connector kit, harness or associated receiver is not assumed to be included unless specifically stated in the quotation.

Configuration checks before installation

Before ordering, compare the complete Part Number, connector keying, modification status and electrical configuration with the removed adapter and aircraft equipment list. The KDA 692 designation alone is not sufficient because related suffixes can have different signal or installation requirements. The photographed modification-marking grid should also be reviewed with the available release record.

Incoming inspection should verify the manufacturer plate, housing, mounting flange, fasteners and connector interface. Bench testing must use approved procedures and the correct simulated signal formats. Any replacement or substitution requires approved technical data and authorized return-to-service action.

Overhauled partner-stock ordering

This 071-1217-01 KDA 692 is offered in Overhauled condition from partner stock with a six-month warranty. Partner availability can change, so current allocation, serial number and EASA Form 1 documentation are confirmed during quotation. The published price applies to the stated configuration and condition.

For an inquiry, provide Part Number 071-1217-01, model KDA 692, required quantity, destination and documentation requirements. Including the installed KR 87, KNS 81, RMI or indicator configuration helps avoid interface errors. Related positions can be reviewed in the Garmin / BendixKing / Honeywell / Collins category; products shown there are related catalog items, not automatically interchangeable replacements.

Before dispatch, buyers may request confirmation photographs of the allocated unit, its manufacturer plate and the corresponding release certificate to resolve the documented serial-number discrepancy.
