[time-nuts] Virgin time nutter fell at the first M12+ hurdle

[Stephen]

Thanks for all the replies so far. (I didn't expect them so quickly :) )

I'm measuring the voltages on Pins 1 and 2 when connected to a max3232 so neither pin is floating.

I have the manuals for the M12 and am aware that it's not NMEA.
The Winoncore software isn't a terminal it is Motorola GPS software and can talk native to the M12

When selecting the ID button Winoncore sends sends:@@Cj
And i expect to see an @@Cj prefixed response string but so far nothing.

I've hooked another max3232 to monitor the txd and rxd lines and there is data being sent to the M12.
Just in case i'm being stupid i've also swapped txd and rxd over but still no response from the card.

I haven't tried NTP yet.
