NMEA 2000® connectors have how many pins?

Explanation:
NMEA 2000 uses a five-pin circular connector to carry all the necessary signals for the network. Those signals include the two CAN bus wires (CAN High and CAN Low) plus the power supply and ground, and an additional pin for the shield/drain. Since the CAN bus needs two differential wires and the system needs power and a ground reference, plus shielding, five pins are required. That’s why the standard connector has five pins.
