Trans-Cal Altimeter Encoder 30K SSD120-30N-RS232

The Trans-Cal SSD120-30N-RS232 is a solid-state altitude encoder/digitizer for pressure-altitude reporting installations. It converts static-system pressure information into ICAO parallel altitude data and provides two asynchronous RS232 serial altitude-data outputs.

Configured for operation from −305 m to +9,145 m (−1,000 to +30,000 ft), this compact Nano-series encoder is intended for installations requiring both conventional parallel altitude reporting and serial data interfaces. The serial-output protocol is selectable independently for each RS232 output in accordance with the manufacturer’s installation documentation.
