Ancor NMEA 2000 Terminating Resistors
Ancor NMEA 2000 Terminating Resistors
SKU:ANC270106
NMEA 2000 Terminating Resistors are placed at the beginning and end of the NMEA 2000 Network. They "cap" the network so there is proper resistance for accurate data transmission throughout.
Ancor Terminating Resistors are color coded yellow. Yellow connectors represent a backbone connection and are commonly placed on the backbone portion of a Tee.
You will need 2 terminating resistors for every complete NMEA 2000 network. Due to the way Tees are designed you will typically have 1 female and 1 male terminating resistor for every network. Besides the connection gender the resistors are electrically identical. If your particular network has 2 males or 2 females it's fine. There just needs to be 2 capping every network.
- Available in Male & Female
- NMEA 2000 approved
- Compatible with all NMEA 2000 devices and brands

Specifications
Terminating resistors "cap" a single NMEA 2000 network for proper data transmission.
Can be purchased in Male or Female connectivity.
Installation Details
Installation Details
In the NMEA 2000 network a "Male" connector is the connector with the exposed pins. The "Female" has the pin sockets. Ignore the connector itself and focus on the pins to determine gender.
Ancor terminating resistors have Yellow connectors. they are designed to connect at the end of the backbone (see diagram) to the yellow connectors on the backbone Tees.
Pelagic Power Tip
Pelagic Power Tip
Terminating resistors are just that, resistors. They have a resistance value of 120 Ohms each. When 2 are properly placed in a network the network will have a total resistance of 60 Ohms because the resistors are placed in parallel.
A great way to diagnose a malfunctioning network is to measure the resistance with a multi-meter via a drop cable. If the resistance is 120 ohms then that network is missing a terminating resistor or has a bad one. If the network has less than 60 ohms the network has too many terminating resistors.
Resistance in a network can only be properly measured when powered is disconnected.
