Visit Preferences to set your user name Summary of change: '''For VR sensor''' * VR input is needed''' * or [https://shop.vems.hu/catalog/hall-p-162.html VR => HALL adapter] and HALL input ---- For '''HALL sensor, HALL input is needed''' VR input will normally not work (or worse: might work unreliably) '''VR input expects the signal to go negative''' (as a VR sensor...) and HALL sensor signal is positive between 0V (or rather +0.2V in practice) and +4..5V (because of 2k7 pullup resistor to +5V ; this resistor is usually inside the ECU when it has HALL input, otherwise it must be right at the HALL sensor; ) Some trick/hack might be possible (not difficult, but not supported; it might work reliably or not depending on if the installer knows what he is doing ; measuring, scoping, etc... again: not supported) with 470 Ohm and 15..18k resistor divider to get negative signal from mainboard (eg. 15..18k from RS232 -9V available inside on LCD pinheader) theoretically this results in >3V and <-0.01V "square" signal that should be sensed by the VR input, but "your milage may vary"... (again: DISCLAIMER: if it works, fine, but no support for this) http://www.vems.hu/files/sensors/Trigger/stupidVR/HALLsensor_VoltageDivider_schematic.png Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
