NMEA 2000 (N2k) Pair Male/Female Resistor Terminators. Terminating kit for Lowrance Simrad B&G Navico & Garmin Networks
Quick take
This pair of NMEA 2000 resistor terminators provides one male and one female 120 ohm resistor to complete termination at both ends of an NMEA 2000 backbone. It is designed for marine use and is reported to fit correctly and work reliably with NMEA 2000 systems. The key buying caveat is installing terminators at the right locations only, using one terminator pair for the network (not extras).
Pros and cons
Pros
- Includes the required male and female 120 ohm resistor terminators for end-of-backbone termination.
- Purpose-built for marine conditions, with waterproof and dustproof design.
- Universal, intended to work across NMEA 2000 brands.
- Buyers commonly describe an exact fit and trouble-free operation.
Cons
- Correct use matters, using more than one terminator pair on the same network can be a problem.
- It is a termination component only, so it will not replace missing cabling, power components, or connectors elsewhere in your NMEA 2000 setup.
What buyers think
Buyer-review evidence for this terminator kit centers on install fit and basic functionality. Multiple reviewers describe an exact match, “works perfectly,” and reliable behavior within an NMEA 2000 system. There is also limited but positive feedback around overall value and that the item matches what was expected.
Overall, the recurring theme is that the kit is the right type of terminator for completing an NMEA 2000 backbone and is straightforward to use when you need male and female 120 ohm resistors at the network ends. Buyer-review evidence does not provide enough detail to reliably discuss anything like advanced performance differences, compatibility edge cases, or long-term durability beyond the intended marine design.
What these NMEA 2000 terminators do
NMEA 2000 backbone networks need proper termination at both ends to help ensure devices communicate reliably. This kit is built specifically for that job by supplying a male and a female 120 ohm resistor terminator, so each end of the backbone can be terminated correctly.
Who this kit is best for
- Owners troubleshooting unreliable NMEA 2000 behavior: If your setup is missing proper termination, this is a targeted fix for the end-of-backbone resistor requirement.
- Marine electronics installers and DIY boat owners: The male and female pair is convenient when you need to close out both ends of the backbone.
- People building mixed-brand NMEA 2000 systems: The kit is intended to be 100 percent universal within NMEA 2000 use cases.
Who should avoid it
- If you are not terminating an NMEA 2000 backbone: This is not a general-purpose adapter, power solution, or replacement for other network components.
- If you already have termination handled: The kit is meant to be used once per network, installing multiple terminator pairs is explicitly discouraged.
Pros and cons, summarized
Pros
- Correct male and female 120 ohm resistor combination for NMEA 2000 backbone termination.
- Marine-focused durability, with waterproof and dustproof design.
- Universal compatibility intent for NMEA 2000 networks.
- Consistent buyer feedback about fit and that it works as intended.
Cons
- Only useful when you need proper termination at both ends, it will not solve issues caused by missing power, wiring, or connector problems elsewhere.
- You need to avoid over-terminating, because the network is meant to use one terminator pair.
Verdict
If you are building or repairing an NMEA 2000 backbone and you need proper termination at both ends, this male and female 120 ohm resistor kit is a straightforward, purpose-built choice. It is designed for marine conditions and is reported to fit exactly and work reliably, as long as you install it only where it belongs in the network.

FAQ
How many NMEA 2000 terminator pairs should I use on my network?
You should use one terminator pair for the network, and it must be placed correctly at the two ends of the NMEA 2000 backbone. Avoid using more than one pair.
Do I need one male and one female terminator?
Yes, this kit is designed as a matched pair with one male and one female 120 ohm resistor terminator, intended to terminate each end of the NMEA 2000 backbone.
Is this compatible with lowrance, simrad, B&G, navico, and garmin?
It is intended to be universal within NMEA 2000 systems, including common marine electronics brands. Compatibility depends on your overall NMEA 2000 network type and connections.
Is it meant for marine use?
Yes. It is designed with a waterproof and dustproof build for the marine environment.
Will terminators fix any NMEA 2000 issue?
Terminators address termination at the ends of the backbone. If your problem is caused by wiring, power, missing components, or connector issues elsewhere, this kit alone may not resolve it.
