The Weman GPS logger displays the actual speed (speed over the bottom). It works at all speeds (even low). The GPS antenna is used as a sensor, which also allows the direction (course over the bottom) to be displayed. The speed is displayed in analog and the direction is displayed digitally. The signals come from a high-performance 32-channel GPS antenna. Red or yellow backlight.

Used when multiple sensors and devices are installed on the same NMEA2000 network. In this case, each sensor and device must be assigned its own correct instance number.
The installation tool is also used to reprogram the sensor, for example from fuel to water. The Wema N3/N5 is supplied as a fuel sensor as standard, while the Wema N3H/N5H is supplied as a septic tank sensor as standard.
- NMEA2000
- For programming sensors
