wires into the same terminal.
6.1.1 Using with an A300
In 2014, Garmin changed the pulse-per-second (PPS) output of the
GPS16X-HVS from 5 V to 3 V. Units with a serial number 1A4189318 or
greater have a PPS output of 0 to 3 V. For those units, an A300 is needed to
connect the PPS output to a CR800-series, CR3000, or CR1000 data logger.
Those data loggers require the PPS line to have a voltage of 3.8 V or greater.
