The SSD120-(XX) Series High Altitude Nano Encoders are all solid-state devices that measure air pressure and convert the measurements into the ICAO parallel data for pressure altitude transmission via ICAO pressure altitude Gray Code output. These Nano encoders also provide altitude data to ADS-B, GPS, transponders, autopilots, and other navigational devices with two asynchronous RS232 outputs for which the serial data protocol can be individually selected. The user has multiple resolution settings to choose from. Typically, the altitude data is set to 100 feet or 10 feet.
This High Altitude Nano Encoder (Alternate Part# 50N-RS232) includes:
- -1,000 ft — 50,000 ft altitude range
- Altitude Digitizer with two RS232 Output ports
- 15 Pin D-Subminiature Mating Connector (1 ea.)
- 15 Pin Connector Back Shell (1 ea.)
- 9 Pin D-Subminiature Mating Connector (1 ea.)
- 9 Pin Connector Back Shell (1 ea.)
- 1/8 NPT Nylon tube fitting (1 ea.)
- 1/4-inch Tube Polypropylene tee fitting (1 ea.)
- 1/8-27NPT Brass Plug (1 ea.)
Features:
- Dual 1/8-27 NPT static port inlets
- One ICAO pressure altitude Gray code output
- Optional two or five RS-232 compliant data outputs
- Serial ports may be installer configured to transmit separate data protocols (message and baud data)
- Power, ground, and data I/O lines provided on industry standard D-miniature connectors
- Constructed with corrosion-resistant aluminum housing
