The blue and black plastic connectors are from Industrial Fiber Optics (IF-E96E and IF-D91). I draw the schematic based on the original Interface and replaced the SMD components with normal sized components. I couldn&#8217;t find the DIL version of the SMD\u00a0bidirectional binary switch\u00a0(SN74LVC1G66DBVR) so I used the 4066 a Quad\u00a0Bilateral Analog Switch.
