A mode C transponder
requires a source of barometric altitude. The RST-582 (our
number for the ACK A-30 Altitude Encoder) interfaces directly with the
transponder to provide that encoded altitude signal.
The ACK altiutde encoder may be
mounted directly on the top of the transponder mounting tray (if you have room
in the stack) to provide single-point mounting for both the transponder and the encoder.
This encoder carries the full
3-year from date of manufacture warranty from ACK. The encoder, tray,
and wiring harness are included.
This is
the standard "Gray Code" unit. The RS-232 serial unit is available on
special order.
