ACK A–30.9 Encoder
General Description
ACK A–30.9 Encoder encoder works with all modern mode A/C and mode S transponders. The mod 9 configuration reports to 42,000 feet and provides both parallel grey codes and two RS 232 outputs which are jumper selectable in the most popular formats. The RS 232 altitude reporting is jumper selectable in 10 or 100 foot increments. It is plug compatible with all earlier mod 1 through 4, and mod 8 encoders with serial numbers 2,400 through 120,499.
Mounting
The Model A–30 digitizer is designed to be located in the same environmental area as the primary altimeter used for flight reference. Avoid mounting the digitizer in the direct airflow of hot or cold air inlets. The digitizer may be mounted in any position within the aircraft. Use 6–32 fasteners or 5/32″ rivets to attach the mounting tray (P/N A30.03). Make sure the head of the fastener used does not protrude above the recess in the tray.
