Wiring
The rack can be used in failsafe mode simply by providing power to the unit as follows:
- There's a 2 pin connector with beefy pins: connect pin 2 to a permanent 12V though an 80 amp fuse, connect pin 1 to ground. Enable the rack though a switched/ignition 12V feed (10A fuse) to pin 4 (EN) of the smaller data connector.
If you want to use dynamic assist levels, you'll need to connect pin 1 to CAN-L and pin 2 to CAN-H, and send out the RPM on 0x280 where Bytes 2 and 3 are RPM*4. This must be above 600 for it to provide assistance.
The rack broadcasts 0x3D0 and 0x3D2
