I am trying to read the genus meter, It has got an optical port and a few onboard GPIO pins, and the voltage across these pins is 2.8Vdc. I'm unable to identify the serial pins for the communication. I've attached the photo for reference. Can someone please help me with the schematics?
Thanks in Advance.
