Maretron TR-CM NMEA 2000 Male Micro Terminator

Maretron NMEA 2000 Micro Male Termination Resistor

The Maretron TR-CM is an essential 120-ohm male Micro termination resistor engineered to terminate one end of an NMEA 2000 (IEC 61162-3) CAN-bus network trunk line. Every NMEA 2000 network requires exactly two termination resistors—one at each physical end of the main backbone—to prevent signal reflection, data corruption, and communication drops across connected marine electronics.

Two termination resistors are required on every NMEA 2000 network, one on each end of the trunk line. Normally, a male termination is used since male pins tend to point back to the power source. In cases where the gender is reversed, a female terminator may be required.

The inline terminator is used where the network is terminated at a product, for example a GPS or weather station at the top of a mast. 

• Screw terminal connector for positive connections

• Termination resistors are used to terminate both ends of the trunk line
