I am powering up instruments and need to determine whether there is any reason to switch power to devices like the TZTL12 separately from the NEMA instruments like the FI70.
So, on my console, would a single instruments switch that also switched on the NEMA be okay? Or is there any reason to switch the NEMA and the instruments separately?
While this may not seem like a FURUNO question, it actually is because the FI70 comes on automatically and I need to power isolate the device from the NEMA backbone the boat uses, otherwise the thing turns on when I turn on the mains which use NEMA for general switching. And since the NEMA is 12v, I also need to add a voltage converter, along with another NEMA power line and the NEMA power isolater, and another CZONE switch, and a wire, and use a CZONE output (they cost about $500 for 6 outputs) for the 'convenience' of using the NEMA to power the FI70. Yes, that is correct, I need to use 6 additional devices and configure the switch in the software to keep the FI70 from turning on with the house mains.
For the AP display, also NEMA powered, I think I will just leave it go on the switched NEMA circuit. The AP will have a czone switch, but I see no reason to isolate and create another NEMA power line. The AP display does NOT seem to power itself on when the circuit gets powered like the FI70
If the FI70 did not turn on automatically, I would not need any of this xtra work, but like I said, perhaps, I was trying to shortcut and didn't realize it and I suppose the FI70 turning on for larger vessels with 6 of them is nice, but sure would nice to be able to configure it.
Thanks for any advice.
