Hi I'm currenly working on a remote electricity monitoring system using Rpi 3. I have already installed an application to read my meter readings from my EDMI mk7c on my Rpi using wine and it works just fine. However, when I connect the EDMI optical port to my rpi from my meter, it doesn't seem to connect since it also doesn't register on the eziview application. Does anyone know why the port doesn't work or if possible have a solution for this? Thank very much in advance.
Here is the specifications for the optical port I'm using.
