In CambiumSYNC mode deployment, cnPulse is connected in-line between the PoE source/injector and radio's PSU port. cnPulse receives power and data from the PoE source and then generates a signal with power, data and a 1PPS CambiumSYNC signal. This is most often used with ePMP 3000 and PTP 550. It can also be used with the PMP 450i and PMP 450m but note that in this mode, no GPS statistics are available to the radio. The diagram below shows how this mode is connected.
Pay close attention to the ports on cnPulse to ensure it is connected correctly.
