Just received some new NWTS units and sorted the B7971 GPS FLW too - this clock has a reversed PS/2 connector - Pin 1 is Vcc, Pin 2 is GND and Pin 6 is RXD at RS232 levels and 4800 baud. The unit requires $GPRMC once per second - remember to set the NWTS to RS232 levels.
Also gave me an opportunity to dismantle the clock and clean it all out - there's been a steady build-up of fine dust over many years, so a clean was long overdue. I've also set the NWTS units for all my older clocks that don't have inbuilt DST to do automatic DST changeover too...
