: Use a minimum of 22 AWG for signal leads and 16 AWG for A+ and ground leads. Ensure all wires are shielded to prevent radio noise.
Ensure the TO/FROM flag indicates correctly and that the NAV warning flag disappears entirely when a valid signal is received. 6. Troubleshooting Common Issues Problem: Excessive noise or alternator whine in audio.
A common source of installation issues is the incompatibility between older Narco transponders and modern solid-state encoders like the Trans-Cal SSD120. The Narco AT-150/AT-50 series often requires a from the encoder or a modification to the transponder's strobe circuit for proper digital data transfer. The specific procedure is outlined in Narco Service Bulletin AT-50A-5 . A certified avionics technician is required to perform these modifications, as they may void certifications if done incorrectly.
: The unit is designed for instrument panel mounting and weighs approximately 3 pounds. It typically uses a mounting tray with a ramping screw that requires a 3/16" Allen wrench to secure the unit firmly into the mating connector. narco escort ii installation manual full
: Use 22 AWG stranded hookup wire for standard audio, microphone, and data signals.
The Narco Escort II is a compact, self-contained Nav/Com system designed for instrument panel mounting in general aviation aircraft. Unlike traditional units that require external indicators, the Escort II features an integrated "gas discharge" display that provides both frequency readouts and VOR/LOC deviation using a row of lights instead of mechanical needles.
Installation typically utilizes a single 13-pin connector (P301) for power and signal routing.

The is a self-contained VHF COM transceiver and nav indicator (if equipped) designed for panel mounting. Installing it requires precision, attention to wiring, and careful antenna placement to ensure clear communication. 1. Pre-Installation Planning The Narco AT-150/AT-50 series often requires a from
: Connect P301 Pin 12 to an external toggle switch that bridges to an airframe ground.
Understanding the baseline operating parameters is vital before performing any retrofitting or wire cutting. The unit is built primarily for general aviation airframes operating standard DC electrical buses. : Built natively for 14V DC systems .
