1. General
1.1 Introduction
The NKC42 is a universal adapter that allows one/four to connect the existing analog fuel/fresh water/waste water/live well/oil/black water senders
or engine performance sensors to the NMEA2000 network.
Please read carefully and follow these instruction for installation, configure, and usage of the adapter in order to ensure optimal performance.
1.2 Features
The NKC42 has the following features.
◆ Programmable sensor types including fuel, fresh water, waste water, live well, oil, black water, engine oil pressure, engine coolant temp,engine
oil temp.
Programmable sensor number up to 16 per sensor type.
Adapts American standard(240~33 ohm) or European standard(0~190/10~180ohm)resistive senders to nmea2000 network(only useful for fluid
level sensor). Calibrated for any resistance range from 0 to 999 or 999 to 0 ohms.
NMEA2000 Interface.
