[CA] [CA11] Updating EV-1, ACU-200, P70 Software

[Denis+Ellis]

Good news: putting the (same) files on the Navionics CF allowed the 3.09 pkg to be visible. Note that I successfully used the other CF card in the past to perform upgrades but I guess it is over a decade old now and beyond its expected lifetime!

Bad news: the ACU-200 supplying power to the Seatalk bus isn't powering the Seatalk bus! It looks like it's only outputting around 3V. Therefore neither the EV-1 or the P70S are getting power now.

I have ordered a Seatalk NG Power cable to power the bus separately (I will also disable the Seatalk power on the ACU-200 using the DIPswitch). Hopefully that will resolve the issue and allow me to continue the upgrade and that the problems with the ACU-200 Seatalk power don't extend to the Seatalk data capability!

Note also that only the EV-1 and P70S are getting power off the Seatalk bus; the A70D and ACU-200 have their own power supply connections.
