Can I connect a CCGX to a Venus GX to use as the display? I want the connectivity of the Venus (tank inputs, temp inputs, etc.) without having to purchase all of the external VE. Can tank adapters (too expensive). If not, I really just need a way to have a small permanently mounted control display near the rest of the distribution panel in the van. I know I can control and monitor with a phone and tablet, but also want something mounted permanently. Thanks in advance for your help.
