I have a Venus GX connected to a Miltiplus 24/5000/120 with a cat6 cable. I need to be able to change the bulk and float votages on the charger periodically (we have Li batteries, and want to use a different charge configuration when on shore power for extended time than while cruising). Can I use the Venus to do that or do I need to physically disconnect the Venus and plug in my MK3 to USB and run VE config to do that? (Same question for configuring Blue Solar mppts)
