Hi I keep loosing PV reading on CCGX from grid meter just shows 2 dashes, gradually got worst so now not working at all. If unplug rs485 cable and reconnect comes back for bit then goes off again, have bought new cable but doesn’t work, grid meter doesn’t show in device list, leds flash when first connected then goes to single red led (old cable doesn’t have single red led just tx rx leds) should new cable just work or does it new setting up in some way? Thanks
