Energy Meter ET112 Firmware

Energy Meter ET112 Firmware B-1 OK, B-2 firmware no communications at all with controller.

ET112 this meter has newer firmware version B-2 and does not work, with the Victron mulitplus2, i used a older ET112 energy meter with firmware B-1 for testing at it works OK.
Something is different in the firmware as the Victron wont respond, But with the Carlo Gavazzi software works OK for testing etc. checked the Comms setting all the same as the older units.

The Mulitplus2 has all the latest firmware updates and the controller has the latest updates.

Hi Rob, when you say it does not work, do you mean it doesn't show up in the Device List at all, or something else? You have to excuse us software people, when you say something doesn't work we will always ask you to be more specific :-)

Hi Rob,

Yes, technically this is possible (more meters on the same cable), but there isn't any real demand for it and we're working on other more pressing things. Once users start splicing such cables it also adds to our support load when meters don't work. It is absolutely amazing how people will complain about a meter not working without ever suspecting that their own splice might be the problem. We therefore prefer that one cable is used per meter, which is also why the existing option for two meters isn't terribly well advertised.

Hi Izak

Thanks for that info, running two meter on one cable i have no problems at all. There is just a limit on how many address # they except on one cable, you just cant use Address higher than # 3 that at all on just one cable.

Hi Izak, the demand is increasing, :)

identical challenge here, have you considered lifting the number of meters per busline?

Thanks, George

Did you try a terminator 120ohm for 3 meters?

you dont use terminators if your using the usb-rs485 adaptor as its built in, but if you want to be correct the last device on the string you should link terminal 3 to 4 as per the manual
