Summary of change:
Optical primary trigger page for MembersPage/EricN/Trigger Planning on using 12-1 trigger wheel mounted in the distributer. Trying an optical trigger now, followed instructions for Hall sensor on primary trigger as per manual. Have some questions. Went to the local electronics store and picked up an OPB804 optical switch. Built it into this little circuit that I found on the internet http://www.vems.hu/files/EricN/opticaltrigger.JPG Changed the 1k resister to 100ohm, voltage at led is 1.25v to gnd. Using pullup on vems,signal high (beam blocked) is 4.6v, low is .25v to gnd '''(how low does this need to be minimum)'''. Optical trigger no better, pc signal generater the same. Can some one please describe the hall and vr input signal circuit path to me? I get as far as jumper 6 in the schematic and then I cant figure out where it goes from there. Tried following it on the board but I get lost quick.
