Default Simrad, power down

I was updating software other day. Noticed when I had ea unit, separately powered direct to a battery, that when I turn unit off, it takes seconds to actually power down. When in boat, all my electronics are energized thru a toggle switch, controlling a selanoid. When I turn off the selanoid, that drops all power instantly, what effect does that have on normal shutdown off mode of simrads?

The preferred way is to power down by turning the unit off. This allows the software to shut down in an orderly fashion.

They will tolerate losing power like yours do when you shut off the toggle switch. But if done repeatedly you may end up with software glitches, usually these issues can however be resolved by doing a reset which reboots the software and gets it all working properly again.

I always shut down properly. My rationale is that these units are basically computers, and I don't turn my PC off by pulling the plug out of the wall, so why would I do the same thing to my even more expensive marine electronics?

If you use the yellow power control wire connected to to the solanoid and the red and black to the battery. Then when the voltage drops on the yellow wire it will start the controlled shutdown on the MFD.

You will have to check that the power control settings in the system setting is set to slave mode.

That's an issue with my boat n setup. Tower voltage is controlled by relays at helm.
Electronics are all on dedicated circuits, powered by selenoid relay. display, all dc voltage is controlled by selanoid on a carolina classic.
Only way I see is to put in standby?

You have two options.

1. Switch off all equipment manually
2. Control the yellow power control wires for all units from one or more switches. A delay element of some type can be used to make sure the units get time to power down in a controlled manner before the power is cut.

All carolina classics are made this way. Not fun, getting more power feeds in tower legs.
Thanks for the replies, sharing of knowledge.

First time I watched a display power down, and realized that is likely an issue

Is standby mode, equivalent to powering down, for power off?

Standby is switching off the screen back lighting, maybe it's stopping more but that's difficult to know since the screen is black.

I always power down electronics independently before I kill the battery switch or battery power to the electronics.
