The communication between the electronics within the solar boat is build upon the CAN-bus protocol, where the datalogger logs the CAN messages. Pinout of our Binder connectors are:
| Binder Connector pin Number | Wire Colour | Signal on wire |
|---|---|---|
| 1 | White | CAN H |
| 2 | Black | Ground |
| 3 | Gray | Safety |
| 4 | Blue | CAN L |
| 5 | Brown | 24v Power |
Note that the M12 connectors have a different pinout and thus different colour wires. To make compatibility between systems easier the binder connectors are soldered with the wrong colored wires so that plugging in a M12 device results in the right signals being passed to the Binder connector. This Compatibility pinout is shown below:
| Binder Connector pin Number | Wire Colour | Signal on wire |
|---|---|---|
| 1 | Gray | Safety |
| 2 | White | 24v Power |
| 3 | Blue | Ground |
| 4 | Black | CAN H |
| 5 | Brown | CAN L |
Battery (MG) CAN-format (No longer used)
As of now the MG electronics battery is used in the solar boat. Although a new battery is being developed, this MG battery is still in use (as of September '22). Therefore the battery format is given here below.
