Termination Resistors are required on an NMEA 2000 network and are placed at each end of a network trunk cable. Like the double-ended cordsets, the termination resistors are waterproof and continue to function even while submerged in the bilge.• Diagnostic version indicates correct polarity at a glance to ensure proper power connections• Screw connector for positive connection• Termination resistors are used to terminate both ends of the trunk lineSpecificationsData Interface: NMEA 2000Connection: Female Waterproof resistors continue to function even while submerged in the bilge View correct polarity at a glance to ensure proper power connection Screw connector for positive connection | TR-NF Mini Termination Resistor, Female
