A customer has a 3B Pnp (board v3.7 # 6651) and wants to run 60-2 Hall for the primary trigger. Some easy steps I've done :
- Enabled Hall primary trigger : SJ2 closed, SJ6 open, R30 2.7k
- Disconnect LM1815pin12 output from the microcontroller input pin : Removed SJ7 solder-blob on the bottom
- Should be enough according to GenBoard/Manual/InputTriggerHardWare : Yes, confirmed.
- already has the HALL part of the circuit set up from EC36/13)
- What about the transistor, yellow wire, and heat shrinked through-hole resistor ?
- It does not matter if sectrig HALL is inverted or not (since falling or rising edge can be selected in secondary trigger dialog configuration). So if LM1815 output is disconneted, the processor will see the HALL signal
