Narco Escort Ii Installation Manual Full -
If "Narco Escort II" refers to a specific piece of software, hardware, or a device used in a particular industry (like agriculture, navigation, etc.), it would be best to consult the official manual or contact the manufacturer directly for the most accurate and detailed instructions.
Narco Escort II is a legacy self-contained Nav/Com avionics unit. Because Narco Avionics is no longer in business, "full" manuals are typically found through specialty archives like AeroElectric Core Installation Requirements Typically operates on
aircraft systems. For 14V installations, a jumper is required between pins 8 and 10 The unit is instrument panel-mounted. Requires two separate antenna connections: one for (VOR/LOC) and one for (transceiver). Standard 50-ohm coaxial cable like is typically used. AeroElectric Wiring & Pinout (P301 Connector)
The unit uses a rear multi-pin connector (often labeled P301) for all primary electrical interfaces: AeroElectric Pin Number Wire Detail Power Input (14/28V) 18 AWG Red Airframe Ground 18 AWG Black Low Level Audio Output 20 AWG Green (330 ohm) Headphone Audio Output 20 AWG Blue (50 mW / 300 ohm) Mike Audio 20 AWG Brown Intercom Key 20 AWG Yellow Mike/Phones Ground 20 AWG Black Special Functions An internal intercom function is activated by grounding via an external switch when the mike key line is open.

The Narco Escort II is a compact, lightweight (3 lbs) "shared system" avionics unit that functions as either a 720-channel COM transceiver or a 200-channel VOR/LOC NAV receiver, though it cannot perform both functions simultaneously. Unlike traditional indicators, it utilizes a gas discharge display with a row of lights for VOR/LOC deviation instead of delicate meter movements. Installation Specifications
Proper installation requires adhering to specific wiring and mounting standards to ensure airworthiness and optimal signal performance.
Mounting: The unit is designed for instrument panel mounting in fixed or rotary-wing aircraft.
Antennas: The system typically utilizes two dipole antennas—a V-shaped NAV antenna often built into airframe structures (like a canard) and a COM antenna usually made from copper tubing located in the fuselage. Wiring Standards: Signal Leads: Should be 22 AWG. Power and Ground: A+ and ground leads should be 16 AWG.
Protection: A 1.5 amp circuit breaker must be provided between the unit and the aircraft power bus.
Shielding: Shielded wire must be used for radio leads to prevent electronic noise interference. Wiring Pinout (P301 Connector)
The P301 connector facilitates the primary electrical interface for the Escort II. Note that for 14V systems, a jumper is required between pins 8 and 10. 14/28V Power Input Airframe Ground Low Level Audio Headphones Audio (50 mW across 300 ohms) Transmitter A+ Transmitter Key Switched A+ Mike Audio Intercom Key Mike/Phones Ground Intercom Functionality If "Narco Escort II" refers to a specific
An internal intercom feature is available by grounding P301 pin 12 through an external switch. When activated with the mike key line open, the microphone audio bypasses the transmitter and is amplified for use as an intercom, outputting through pins 5 and 6.

Configuration: Some software requires or offers configuration during installation. Make choices that fit your needs, but be aware that default settings are often the best choice for beginners.
Completing Installation: Once the installation bar completes, you may be prompted to restart your computer or directly launch the application.
The manual details the pin configurations for the rear connector (typically a standard rectangular connector). Key connections include: Researched from Narco technical documents
The Escort II uses a circular 19-pin connector (MIL-C-5015 style). Below is the critical pinout derived from the manual:

Critical Warning: Pin 2 (+14V) must be fed from a dedicated "Avionics Master" or "Transponder" breaker. Do not share these with a cigar lighter or landing light circuit. Voltage drop must be <0.5V under load.
The Narco Escort II Installation Manual is not just a suggestion; it is legally required by FAR 43.13 (Acceptable Methods, Techniques, and Practices). Without it, you cannot legally determine:
The Narco Escort II installation manual is a blueprint from a simpler era of avionics. While the company is gone, the hardware remains surprisingly reliable if installed exactly per the original specs. Track down an original Part 057-001-0025, respect the pinout chart, treat your coaxial cable with reverence, and this transponder will happily reply to ATC interrogations for another decade.
Call to Action: If you have a clean PDF of the Narco Escort II Installation Manual (Full, not just the pilot guide), consider uploading it to the AOPA Forums or Vintage Avionics Library. Preserve this knowledge for the next restorer.
