Has anyone interfaced the data output of the GMC200 to a 1-wire counter like the DS2423. It looks like the GMC200 only outputs 1.4V pulses and the DS2423 is looking for > 2.4V??

If anyone has done it, please share; otherwise I'll go ahead and do it.

The GMC-200 uses two diodes to clamp the audio output level to 1.4V. The original signal voltage is 9V.

You can remove two diodes and place a zener diode instead.
