Maretron MRT TR-CM Micro Terminator Resistor - Male. 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.

o Screw terminal connector for positive connections
o Termination resistors are used to terminate both ends of the trunk line
