Hi Guys
Does anybody within ENAC labs know how the Pentax remote E featured in the attached photo (supplied by Pascal Brisset) is wired to the I2C sda & scl pins on a Tiny 2.1 utilising the digital_cam.xml (DC) module?. 
I have ascertained that an opto-isolator would do the job. But the remote board featured in the photo seems not to have this feature attached.
Maybe there is a better, smarter and lighter way?
Thanks in advance.
