Hi all you clever people.

Is there anyone that have implemented boat mode in their inverter?

I am running parallell tracks here, both trying to get the "ordinary car mode" working in my boat, and understanding how to implement boat mode, if needed.

In other threads/topics I have gathered some bits and pieces. But there is still plenty I don't understand. Such as, is pot-mode bidirectional a requirement for boat mode, or is it an option?

We have a Curtis ET-134 FNR and throttle combi controller installed in the boat, which I am trying to use. In parallell I am getting help piecing together an arduino that will convert signals from the combi controller to CAN messages. Question is which signals/messages/values I should convert to, to make things as simple and stable as possible.

All knowledge and experience about boat installations in general, and boat mode in particular, are appreciated

Ok, I said I'm stepping away from inverters but I'm afraid nobody else knows this. Of course the code has all the answers

Boat mode has two options
a) throttle input is not treated as a torque command but as a speed command (cruisemode=ThrottlePot)
b) Throttle is center aligned, pulling it back puts direction to reverse, forward to forward (potmode=BiDir or CANBiDir)

The two can be but don't have to be combined

Thank you @Johu,

One question that comes to mind is, is there a parameter for deadband, when using potmode=bidir? If not how much play is it around the center value before either ”gear” is selected?
