Looking for some assistance on getting an ET340 working with a CCGX, CCGX is V1.74 does this support ET340 as menu looks to be different to what manuals indicate. I'm using 5M USB to RS485 Victron cable, no interference across installation, orange,yelow and black as instructed, CCGX does not see ET340 at all, plugged into USB host port on CCGX, no red or green flashing light (only on initial plugging in, then only get a solid red led (not the traffic led). Tried connecting ET340 to a Win 7 home PC with Carlo UCS7 software but that doesn't appear to work either. Have tried multiple USB ports, various USB to RS485 cables that I have on hand, linked in 120Ohm resistor on ET340. No luck at all, thinking I have something DOOB but thought I'd throw it out there for advice.
