Capen" Subject: Avionics-List: 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 ________________________________ Message 2 _____________________________________ Time: 10:48:30 AM PST US From: "Gaby Levin" Subject: Re: Avionics-List: Grey code output to multiple devices forget it! makes no sense ----- Original Message ----- From: "Ralph E.

The serial port on the GPS is being used for something else and it has grey code lines also. 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. -- --> From the U S of A, the only socialist country that refuses to admit it. <-- ________________________________ Message 4 _____________________________________ Time: 11:50:59 PM PST US From: =?ISO-8859-1?Q?Georg_Isenb=FCrger?= Subject: Re: Avionics-List: Grey code output to multiple devices 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. regards George Am 29.05.2009 um 00:32 schrieb Doug McNutt: > At 20:48 +0300 5/28/09, Gaby Levin wrote: > > forget it! > makes no sense > > ----- Original Message ----- From: "Ralph E.
