Product details
Description and Specifications
NMEA2000 Smart Universal Micro Terminator
Terminate your NMEA 2000 network – regardless of whether a male or female connection is required – and use the TER-U’s smart functionality to easily diagnose any power or voltage issues on your NMEA 2000 bus.
The TER-U can be fitted directly at the end of your network or used as an in-line terminator in difficult-to-access locations.
The TER-U acts as an intelligent diagnostic terminator, providing instant feedback on the state of the NMEA 2000 bus onboard. It is also a universal terminator which can be used as an inline terminator or else as either a Male or Female terminator, as it comes supplied with blanking caps.
It has a built-in high-accuracy voltage monitoring circuit, which continuously monitors the bus voltage, and will illuminate its internal LEDs when it detects that the bus voltage is of the correct polarity. If it detects that the voltage is within the minimum required range, it will indicate ‘GREEN’ immediately, providing continuous, valuable feedback as to the state of the bus.
If the voltage falls below the minimum required level of 9.0V, then the LEDs will illuminate ‘RED’, showing there is a potential problem with the NMEA 2000 bus power. Similarly, if the LEDs do not illuminate at all, this would indicate that there was no power or that the polarity was incorrect. This monitoring function happens continuously and remains permanent.
Because these terminators are illuminated, they instantly provide feedback that the terminator is actually present (i.e., able to identify that there are two terminators present) – especially helpful in difficult-to-reach locations.
This smart universal micro-terminator can be used as either a male or female terminator or even as a feed-through terminator for applications at the top of masts, making it truly universal.

FAQs
Please read our FAQs page to find out more.
When will my order ship?
For in-stock items, orders placed by 4:00 PM EST are eligible to ship the same day. If any item in the order is not currently in stock, shipment timing will depend on availability.
What is your return window?
Eligible merchandise may be returned within 30 days from the date of receipt. All returns require a Return Merchandise Authorization (RMA) number before anything is sent back. For the smoothest experience, we ask customers to contact Salina Vita first so we can coordinate the request properly. Returned merchandise must be complete, in its original packaging, and in resalable condition. Items that arrive incomplete, improperly packed, or not suitable for resale may not qualify for return approval.
Are restocking fees possible?
Yes. Approved returns may be subject to a restocking fee of up to 15%. Non-stock items may not be returned. In addition, opened or unsealed DVDs, CDs, and cartography products are non-returnable unless defective. If the product falls into CWR’s excluded media categories—such as opened or unsealed cartography, DVDs, or CDs—it is not returnable unless defective.
If my unit needs warranty service, should I send it back to Salina Vita?
No. Units requiring service, whether under warranty or otherwise, should be returned directly to the appropriate manufacturer, not to Salina Vita. We are always happy to help guide you to the correct manufacturer support path. Absolutely. While the service destination is the manufacturer, we can help you identify the proper support channel and make the process feel more straightforward and well-managed. Units that require service themselves, however, should go directly to the manufacturer under CWR’s policy.
I still have more Questions, can we contact you?
At Salina Vita, we believe premium marine commerce should feel measured, transparent, and reassuring. If you have a question about a shipment, return eligibility, or manufacturer service, contact us before taking the next step and we will guide you with the discretion and clarity your vessel deserves.
