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.• Used To: Terminate Both Ends Of The Trunk Line• Type: Micro 5-Pin Female Termination Resistor• Color: Blue/ Gray• Quantity: Single Inline Terminator Is Used Where The Network Is Terminated At A Product Waterproof Rated To IP67 | Maretron Marine Network Cable Terminator in Blue
