Car Kit Car-Kit 91

[chrisharlow]

Does anyone have schmatics or information on the -91 Car Kit? I would like to covert one to connect to my audio panel( KMA-24H) in my plane and use the PTT function to reduce the echo suppression issue.

Thanks, Chris Harlow

Here are the schematics for the original carkit CARK-91.
Do you know the communication protocol between the nokia 6310 and the original carkit CARK-91?
I tried to listen on the MBUS, with a nokia 6310i and my THB carkit. It seems that when the carkit identifies himself on the MBUS, the phone doesn`t answer anymore. I tried it with a 6110 and it answers.
Can you do the same thing with the original carkit and a 6310, and post the results (terminal windows) on the forum or by mail?
The settings are 9600 bauds, 1start, 8data, odd parity, 1stop bit.
I listened the communication with a terminal program, directly in hex.
Thanks,
Zoli
