Pin assignment of the Bluetooth Box and Y-cable

The pin assignment and standard connections of the Bluetooth Box.

Pin assignment of the Bluetooth Box


1: Sensor input Usually for fresh water
2: Sensor inputUsually for grey water
3: Sensor inputUsually for black water
4: Sensor inputOptional input (e.g. for diesel tank, GasCheck)
5: Power supply10 - 30V DC


Note: The sensor inputs can be freely assigned in the SuperSense app, it is only the default configuration that allocates each tank as described above. Any tank can be freely assigned to any sensor input in the app.



Y-cable for the Bluetooth Box


An optional Y-cable is also available for the Bluetooth Box, which allows the level signals to be transmitted additionally to the original on-board electronics. Currently, the panels are supported by Concorde motorhomes (CBE) and MORELO motorhomes (CBE). This means that the level indicator remains visible on the original vehicle electronics. The cable may only be connected as shown below:





Connecting the Bluetooth Box to CBE


Below you will find a pin assignment, valid for many original CBE boards (e.g. Concorde, MORELO, Niesmann+Bischoff, etc.):





38 (black)Input signal for black water sensor, standard assignment at Bluetooth Box: Port 3
39 (green)Input signal for grey water sensor, standard assignment at Bluetooth Box: Port 2
40 (red)Input signal for auxiliary sensor, where e.g. the GasCheck sensor can be connected to enable the gas tank level to be measured at the CBE. Standard assignment on Bluetooth Box: Port 4
41 (white)Input signal for fresh water sensor, standard assignment at Bluetooth Box: Port 1
43+12 V. Can be used for the Bluetooth Box. Recommended fuse: 500mA
44Ground / GND. Can be used for the Bluetooth Box




Important notes:

  • Only allow electrical work to be carried out by appropriately trained specialists.
  • Check all cables for correct function / wiring before installation.
  • Always carry out work in a de-energized state.
  • Disconnect all original probes that may still be present - especially when the Bluetooth Box is put into operation, as many original probes work with 5V and the SuperSense receives a supply voltage of 12V from the Bluetooth Box.
