The VE.Direct cable using 2 wires to send data to the Cerbo can I connect the other two wires to a different device?
My problem is that I have a 40-foot RV with a SmartSolar Charger, MultiPlus-II, and SmartShunt all the way in the back, and the Cerbo-S GX is all the way in the front. It’s very hard to run any new cables. I’m using an old 4 wire telephone cable from the previous inverter and I added VE.Direct connectors to it, and it works fine.
Here’s a typical pinout for a VE.Direct cable:
1. VCC (power)
2. GND (ground)
3. TX (transmit data)
4. RX (receive data)
So, while the cable has four wires, only two are actively used for sending and receiving information. The other two are used for providing power and grounding, so if the SmartSolar Charger, MultiPlus-II, and SmartShunt they all getting power from the battery, technically don't need power from VE.Direct cable right?
