According to another post, I only need the ILLUM_P and ILLUM_EN pins to use another illumination source. Is this what the J2 header is for? I see what looks like useful output on pin 2 of J2 for the enable signal, but it is called ENz. What is ENz for, exactly?
I would like to avoid splicing the the J1 header cable to get the ILLUM signals out, are the signals from J2 the same as ILLUM_EN and ILLUM_P from J1?
