Adamw Posted August 31, 2021 Report Share Posted August 31, 2021 If you use an Aux output (not ignition or injector output), the speedo output will give a 0-12V square wave. It should work directly with that speedo, no extra pull-up resistor is needed. Quote Link to comment Share on other sites More sharing options...
keizsr Posted August 31, 2021 Author Report Share Posted August 31, 2021 Hello, Adamw. I understood that the pull-up resistor in the pdf is not needed. What about the aux active state setting in the speedometer output settings? Is it low or high? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 31, 2021 Report Share Posted August 31, 2021 It doesnt matter because the signal is 50% duty cycle square wave. Low active state will give exactly the same result as high active. Quote Link to comment Share on other sites More sharing options...
keizsr Posted August 31, 2021 Author Report Share Posted August 31, 2021 Adamw. Thank you for everything. I understand now. Quote Link to comment Share on other sites More sharing options...
