1PPS Signal

There is a dedicated 1PPS signal available on the Serial Connection of the GC2-SER Serial variant

The signal is normally low and pulses high for 100 milliseconds to signal the precise second, which starts on the rising edge of the signal.

This dedicated 1PPS signal is the recommended 1PPS signal to use as it is more accurate. The validity of this 1PPS signal can be monitored using the time initialised status flag.
