Note: If your aircraft uses modern RS-232 serial data for altitude formatting, a serialization converter or an encoder that outputs parallel Gillham code is required for standard KT 70 legacy installations. 5. Antenna Installation and RF Cabling

Cause: A broken wire in the Gillham code harness, a misconfigured encoder, or a lack of power to the altitude encoder.

Verify that the altitude displayed on the ramp test equipment matches the aircraft’s primary altimeter within +/- 125 feet across the certified altitude spectrum. 4. RF Cable and Antenna Requirements

This consolidates manufacturer data, user experience, and technical specifications to help you install, configure, and troubleshoot your KT-70 display safely and effectively.

Connect to a compatible blind encoder (e.g., KEA 130A) or directly to an Air Data Computer (ADC).
