Hello,
It is recommended in the ET112 manual to use an RS485 to USB cable. This is what I'm going to do to be Ok.
But I read at the bottom of page 4 (pdf): "The red, green and brown wire coming out of the USB to RS485 cable are not used. Note: You can wire on a RJ45 plug which can plug into the front of either RJ45 socket of the Energy meter, it has the same pin out. "
It is understood that it is to lengthen the cable.
I'm curious and my question is in two parts:
- what are the two RJ45 sockets on the front of the ET112 for?
(Matthis replied in another post that these are not ethernet sockets).
- can we connect an ET112 and a Cerbo GX in RJ45 to RJ45 (Cerbo's BMS-Can socket)?
Thank you in advance for your answers which may help other people.
Kind regards
