Actisense NMEA 2000 Smart Universal Micro Terminator – A2K-TER-U

Ensure optimal performance and network reliability with the Actisense NMEA 2000 Smart Universal Micro Terminator (A2K-TER-U). Designed for modern marine electronics systems, this innovative terminator automatically adapts to your NMEA 2000 network, simplifying installation while ensuring proper signal integrity.

Unlike standard terminators, the smart universal design eliminates guesswork by automatically configuring itself for correct network termination. This helps prevent communication errors, signal reflections, and data loss—keeping your onboard electronics running smoothly.

Compact and easy to install, the A2K-TER-U is compatible with Micro-C NMEA 2000 networks and is an essential component for maintaining a stable and efficient marine data backbone.

Key Features:

• Universal Fitment: This is a truly universal solution. It can be configured as a male or female terminator using the included blanking caps, or used as an in-line terminator for difficult-to-access locations.

• Instant Diagnostics: The built-in monitoring circuit provides immediate feedback via internal LEDs.

  • Solid Green: Indicates the bus voltage is healthy (above 9.0V) and the polarity is correct.

  • Solid Red: Alerts you that the voltage has dropped below the required 9.0V, signaling a potential power issue.

  • No Light: Indicates a total lack of power or incorrect wiring polarity.

• Visible Presence: Because the unit illuminates, it is easy to verify that the required two terminators are present on the network, even in dark or cramped bilges

• High Reliability: Built with high-accuracy monitoring components and a rugged, waterproof housing to withstand the marine environment.

• Smart universal NMEA 2000 terminator for reliable network performance

• Automatically configures for proper network termination

• Prevents signal reflection and data communication errors
