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

[CA11] Updating EV-1, ACU-200, P70 Software
I'm trying to update my autopilot equipment software versions that seem to be on the original revs; is it possible to do so with the P70 off the network (for repair)? I'm using an A70 as the MFD and a correctly formatted/sized CF drive for the upgrades.

I can see the pkg options on the MFD but when I try to start the upgrade process it doesn't proceed. Also I'm surprised to see that Seatalk NG is not an option for transporting the updates to the other pieces even though that is the actual network being used. NMEA and Seatalk 2 are the options shown on the MFD; nothing happens when I try the NMEA option and selecting the Seatalk 2 option does try to do something but it times out. See the attached screenshot.

Should the light be on the EV-1 when powered or does it rely on the P70 to get powered up correctly? At present it does not show any light.

RE: [CA11] Updating EV-1, ACU-200, P70 Software
Welcome back to the Raymarine Forum Denis+Ellis,

You may have indeed identified the source of the issue, as indeed the EV-1 CCU's LED should be illuminated. Autopilot control heads are powered by the backbone ... they do snot supply power a backbone. Some autopilot course computers and some ACUs are designed to supply power to a backbone. While it is considered to be a best installation practice to power the backbone via a SeaTalkng Power Cable which has been powered from a dedicated switched 12VDC power circuit, within small system (i.e. those featuring simply a MFD and an Evolution autopilot), some will elect to power the backbone from the ACU. A dip switch is provided on interface panel of the ACU-200 and ACU-400 to switch power on/off from the ACU. In this case I suspect that you will find that either the ACU is not powered ON or the circuit which is responsible for supplying power to the SeaTalkng Power Cable is switched off.

Thanks Chuck. See the attached shot of the ACU which to me does look like it is trying to power the backbone. The DIPswitch looks like it's set to ON but the LED is red; should it be green? I have not had a chance to probe for power on the backbone yet but all bar the P70 on the simple network had been working satisfactorily up to recently. See separate thread on the P70 issues.

Denis+Ellis,

The SeaTalkng power switch features two LEDs. When the switch is moved to the OFF position, the green LED to the left of the switch will be illuminated. When the switch is moved to the ON position, the red LED to the right of the switch will be illuminated. Within systems featuring more than a MFD and an Evolution autopilot within the backbone, it is recommended that the backbone be powered according to the best practice indicated within my last response to prevent under-powering the backbone. If the other devices meant to be powered by the backbone appear to be powered and the Status LED of the EV-1 not be illuminated, then there is either a fault with the EV-1 or the networking components connecting it to the backbone.

I cycled the DIP Switch for Seatalk NG on the AC-200 and I reseated the connector and managed to get power back to the EV-1. I could then proceed with the update to the EV-1 and AC-200 using the MFD.
Thanks for your help!
