A Simple Yet Robust Altitude Data Simulator Device

ADS-100 Altitude Data Simulator

Simulate RS232 and ICAO Parallel Pressure Altitude Data with a Single Test Box!

The Model ADS-100 is an all solid-state device that simulates the output of altitude encoders/digitizers in both parallel and serial (RS232) data formats. Designed to substitute for an altitude encoder when testing and troubleshooting an aircraft’s altitude reporting system, the ADS-100 provides two RS-232 compliant outputs in addition to the ICAO pressure altitude code. The Model ADS-100 provides a simple and robust means of simulating serial and parallel altitude data inputs for multiple aircraft systems.

The bright two-line vacuum fluorescent display gives the test technician a view of the current altitude code transmission on both the serial and parallel ports. LED indicators display the status of the encoder strobe, power and serial data protocol pins, as well as the binary ICAO altitude code. Audible alerts are generated at 1000’ or 100’ altitude code transition points. Front panel switches control the device power, altitude hold, ascent/descent rate, audible signals and serial data protocol.

ADS-100 Features:

  • A fan-out of two RS232 serial altitude output ports
  • One standard ICAO pressure altitude output port.
  • RS-232 ports may be user configured to transmit one of six standard serial altitude messages.
  • Climb/descent rate is selectable, 6000’/min. or 30,000’/min.
  • Audible alert, user selectable at 100’ or 1000’ increments
  • LED indicators of active ICAO code bits, power, strobe and protocol
  • Bright 24 character 2-line vacuum fluorescent display
