Summary of change:
VEMS V3.9 AAN is by default Conversion to VR, HALL if ever needed for a non-factory setup. '''InputTrigger/AudiTrigger with camHALL inverter, which means:''' * '''primtrig=VR''' (VR on crank as you prefer, nothing to do there) * '''sectrig=Auditrigger with camHALL inverter''' ** pulling camHALL input = GND or 100 Ohm resistor to GND would allow sectrig=VR to go through unmasked (if sectrig=VR needed) ** '''convert to HALL by:''' disabling the 2nd LM1815 by '''removing''' the sectrig LM1815 (U110 ?) output '''SJ7 solder-blob on the bottom''' (that connects LM1815pin12 output to the microcontroller input pin). This blob is on the bottom, under the FETs. output solderblob at the bottom side under the FETS so that HALL signal will reach the processor and work (VR will be ineffective as a result). http://www.vems.hu/files/ErikEnglund/pictures/IMG_0013.jpg If you need to check, basically same HW since v3.6 (eg. v3.8 or v3.8b), see "See also" below ---- '''For secondary trigger HALL''' (or sectrig unused) * either a small blob ("electric-short" or small resistor 1k or lower) is needed between the SOT23 NPN (base and collector) * or the NPN transistor is also perfect ** NPN inverts the signal, which is also good: sectrig edge is config-selectable falling/rising, just invert when moving config from ECU without camhall inverter to an ECU with camhall inverter. * and capture and verify Tools / triggerlog http://www.vems.hu/manual/html/images/Testing/v3.6_sec_trigger_1_m.jpg ---- '''See also:''' * GenBoard/VerThree/Schematic * InputTrigger/AudiTrigger * GenBoard/Manual/InputTriggerHardWare
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
