ROVL MK 3 Tx connection

Hello everyone,

I have a couple of questions about the latest version of ROVL MK III.

First one : for powering the TX UNIT (the one mounted on BROV).
Following your suggestion in the previous FAQ, do we still have to connect the Black and the Green wire leaving the White free disconnected and sealed?

Second question: what does CIMU mean?
It that appears in the dashboard.

Thanks
