The TER-U is an intelligent diagnostic terminator providing instant feedback on the state of the NMEA 2000® bus it is connected to. It is also a universal terminator, meaning it can be used as an inline terminator or else as either a Male or Female terminator, as it come supplied with blanking caps.

It has built-in high accuracy voltage monitoring circuit which continuously monitors the bus voltage. It 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 LED’s will illuminate ‘RED’, showing there is a potential problem with the NMEA 2000® bus power. Similarly, if the LED’s 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.
