Hi All,

A query about what NMEA sentences that Larry's version 3 card will read.

 

I have 2 GPS based time generators, one quite old (built into a rack I'm
adding a PSN card to) that outputs GPGGA and GPVTG strings @4800 baud that
doesn't work with Larry's board and a VNG emulator / time server I built
that outputs GPGGA and GPRMC strings @4800 baud that does work with Larry's
board

 

Both work fine with Tardis2000 v1.6 and both have a 1pps signal (going Hi on
the start of the second) on the DCD line.

 

So I'm guessing Larry's card is happy with the GPRMC string and not a GPGGA
or GPVTG string.

Anyone know of any other strings that Larry's card is happy with?
