The VE.Direct to VE.CAN interface cable can be used to make BMV-700 information available on a VE.Can network. Where it can be read by a Color Control GX for example.
The interface cable does not work with other VE.Direct products, such as Solar Chargers, Inverters and also not with the BMV-712 Smart.
When used in combination with a BMV-702 there is limited functionality with regards to the AUX function in the BMV: When used to measure starter battery voltage, that voltage will be transmitted to VE.Can. But when used to measure temperature and/or mid-voltage, that data will not be transmitted on the VE.Can network.
