[time-nuts] Z3805 utility, Was: AW: (no subject)

[jmfranke]

Have you looked at the serial connector with an oscilloscope?  Pin 2 should 
be the output data.  Pin 3 is for data going into the GPS.  And pin 7 is 
ground.  I use Z3801A systems which have a 25-pin connector.  Other systems 
use a 9-pin serial connector.  The only difference should be the ground 
which is on pin 5 for the 9-pin connector.  Have you looked at:
