Actisense NMEA2000 Smart Universal Micro Terminator A2K-TER-U

NMEA2000 Smart Universal Micro Terminator

Terminate your NMEA 2000 network regardless of whether a male or female connection is required and use the TER-Us 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 intelligentdiagnosticterminator, providing instant feedback on the state of the NMEA 2000 bus onboard. It is also auniversalterminator 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.

The Actisense NMEA2000 Smart Universal Micro Terminator (Model: A2K-TER-U) is an essential component for ensuring reliable termination and diagnostics on your NMEA 2000 network. Designed to be versatile, it can be installed at the end of your network or used inline in difficult-to-access locations, providing a flexible solution for various marine electronics setups. This intelligent terminator not only completes your network but also offers real-time diagnostic feedback, making it easier to maintain and troubleshoot your data bus.
Equipped with a high-accuracy voltage monitoring circuit, the A2K-TER-U continuously checks the bus voltage and provides visual indicators through built-in LEDs. When the bus voltage is within the correct polarity and above 9.0V, the green LED illuminates, signaling a healthy power supply. If the voltage drops below this threshold, the red LED lights up, alerting you to potential power issues. If neither LED is active, it indicates that power is absent or incorrectly polarized, allowing quick identification of issues without additional tools. The illuminated LEDs are particularly useful for installations in hard-to-reach areas, offering instant confirmation of proper terminator placement and power status.
This universal micro-terminator is designed for compatibility with standard M12 connections, featuring brass, gold-plated male contacts and phosphor bronze, gold-plated female contacts. Its robust construction includes black PA66 (30% glass-filled) contact carriers and a durable PVC black housing rated for IP67 protection when mated, making it suitable for harsh marine environments. The device supports a rated current of 4A and operates at 36VDC, with a termination resistance of 120 ohms ±1%. Its compact design weighs only about 0.7 ounces, making it unobtrusive and easy to install at critical points on your vessel.
Whether used as a male or female connector, or as a feed-through in mast applications, the Actisense A2K-TER-U offers unmatched flexibility and reliability. The product complies with industry standards and has been tested for operating temperatures ranging from -20°C to +70°C, with storage capabilities from -40°C to +85°C. Certified with an IP67 rating when mated, it provides dependable performance in marine environments. For comprehensive guidance, the product manual is available online, ensuring proper installation and troubleshooting. Invest in the Actisense NMEA2000 Smart Universal Micro Terminator to enhance network stability and simplify system diagnostics on your marine vessel.
