VE.Direct Cable Length

Hi there.

Situation: Battery, MPPT Smart Solar and Multi are in the barn, CCGX ist in the living room.

VE.Direct max. Cable length is 10 meters. Distance I have to build is 20-25 meters.

Any ideas? Maybe convert VE.Direct Protocol to CAN? Or just use some BUS Amplifiers such as 7406? (I am an eduacated electronic technician with no fear of soldering irons :-)

Or convert VE.Direct to any other Protocol such as TCP/IP? Wireless/ BT is no good idea because of some thick walls.

Thank you very much for helping!

Greetings

Steve

The cheapest solution that MAY work is to use the VE.Direct to USB adapter, and then an Active, powered, boosted USB extension cable. I have done that for 1.5M + 15M before and it worked fine.

This one claims up to 50M - but is a bit expensive.

That sounds good. And it does take not much effort. Thank you.

For further developments: I'm sure there are many people out there who have their Displays in their living space. An ethernet connection would be much better.

Finally found a solution: After 10 Meters inserting a standard TTL 7407 will do the magic: It works :-)

Maybe some other guy out there will be thankful for this hint.

Have fun!

me curious too, have the same issue, think 10 meters is just a 2-3 meters to short :(
