Mercury – NMEA 2000 Termination Resistor (Female) | Network End Resistor | 8M6004831

Overview

Every NMEA 2000 backbone needs two termination points—one male and one female—to keep the network stable and prevent data noise. The Mercury 8M6004831 NMEA 2000 Female Resistor provides one of those end-of-line terminations. It installs at either end of the backbone (whichever side uses a female port) and helps ensure clean, reliable communication between all N2K devices on board.

Key Features

• Female-Termination Resistor – Provides the required end-of-line resistance for NMEA 2000 networks.
• Standards-Compliant – Built to N2K specifications for correct electrical loading.
• Backbone Stability – Helps maintain clean data flow and prevents signal reflections or dropouts.
• Plug-and-Play Design – Connects directly to any female NMEA 2000 port on the network.
• OEM Marine Quality – Durable construction suited for vibration, moisture, and long-term use.

Compatibility

• All NMEA 2000 networks
• Standard 5-pin NMEA 2000 Micro-C connectors
• Systems requiring female-end termination (paired with a male resistor)

Performance & Practical Benefits

This resistor helps finalize your NMEA 2000 backbone by providing the proper electrical load at one end of the system. Without correct termination, networks can experience communication dropouts, device resets, or inconsistent sensor readings. Once connected, the backbone stays stable and devices communicate the way they’re supposed to.

Why Buy OEM

Termination resistors must meet exact electrical specs to keep an N2K network healthy. Mercury’s OEM resistor ensures correct resistance, solid connector fit, and proper sealing—qualities that cheaper substitutes often lack. A reliable terminator protects the entire network from hard-to-diagnose performance issues.

FAQ

Q1: Do I need more than one resistor?
Yes. An NMEA 2000 backbone requires two: one male and one female.

Q2: Where does the female resistor go?
On the end of the backbone where the final connector is female.

Q3: Will this work with non-Mercury N2K devices?
Absolutely—it's fully NMEA 2000–compliant.

Q4: Does this power the network?
No. Terminators only stabilize the data bus. A dedicated power node is still required.

Q5: Is installation simple?
Yes. Plug it into the open female end of your N2K backbone and the network is properly terminated.
