Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: '''Historical hardware setup subpage''' of InputTrigger/AudiTrigger '''For v3.0 .. v3.2:''' * easy: connect the pullup of secondary LM1815 output to cam-HALL signal instead of direct 5V. Ask for help if this is not clear. '''For v3.3 shipped in 2005:''' * GenBoard/Manual/InputTriggerHardWare/ReplaceC is effected, removing the 220nF from C103 is necessary (or or replacing with 1nF new value) * added 1uF cap in parallel with C40 (eg. piggyback on top, or replace) for longer peak hold time (might be essential depending on crankhome-VR noise, and does not hurt) * 12..15k pullup to +5V for crankhome VR signal (a good place to mount a 1206 size resistor is between board-pad and 5V at primary LM1815 pin8) ** alternatively 10k pulldown to -8V ** or 1k pulldown to GND (0V) and adaptive hysteresis disabled, that is LM1815 pin5=+5V '''For v3.3 shipped after 2006:''' - done at assembly if requested in shop order note * added 1uF cap in parallel with C40 (eg. piggyback on top, or replace) for longer peak hold time (might be essential depending on crankhome-VR noise, and does not hurt) * 12..15k pullup to +5V for crankhome VR signal (a good place to mount a 1206 size resistor is between board-pad and 5V at primary LM1815 pin8) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
