| Subject: | Grey code output to multiple devices |
Folks,
I have a Narco AR 850 grey code altitude reporter. I would like to connect it
to two devices (GPS and transponder) instead of just the transponder. The serial
port on the GPS is being used for something else and it has grey code lines
also.
Both the GPS and transponder have diode suppression in the grey code lines in order
to prevent an off unit from dropping the signal to low.
What say ye.....can I do this - or will smoke escape....?
Thanks,
Ralph Capen

I suspect that the gray code from the GPS is an output rather than an input. At
the very east you would have to get design information from the folks who designed
the GPS.
The Narco interface emulates a "standard" encoding altimeter which simply grounds
the wires to indicate a one bit. It's not to be confused with Intel serial
port or an RS232 type of connection.

I have the following installation:
KLN-94 GPS and a KT-76A Transponder. They both get the grey-code from
my ACK encoder. They're simply wired in parallel. It works fine.
