KLN-94 RS-232 Altitude Encoder Input?

[Darryl Snover]

I'm in the process of replacing my old and failing altitude encoder, with a new ACK A-30 Mod 9. I'd like to use the RS-232 output for the KLN-94 GPS, to take advantage of the simpler wiring, if possible.

Any avionics techs here that have knowledge of the KLN-94 that can tell me if the KLN-94 will accept the RS-232 input, rather than having to re-wire all the grey-code pins?

The KLN-94 only supports 4 RS232 input formats (Formats A-D referenced in the manual) and is more geared towards receiving fuel data. Formats C and D do support receiving pressure altitude along with fuel data, but your Ack does not support outputting in any of those formats, so you'll need to keep the grey code lines.

Thanks. Exactly the information I was looking for.
