D14-D16 wiring.
V3.57 added pinouts for the 3 LED's, PAD's 1-3, which is great, no more jumpers to the LED, but also added a second Vcc source to those PADS.
V3.0 doesn't have that second source and I'm not sure I understand it's purpose. Any info appreciated.

Re: D14-D16 wiring.
I'm not sure I understand your question. What exactly are you trying to learn?

Re: D14-D16 wiring.
V3.0 of the MS is pretty straight forward. V3.57 added the pinout, PAD 1, so a jumper soldered to the LED was no longer necessary
you can use PAD 1. What I don't understand is the function of the second Vcc source, (circled). Thanks.

Re: D14-D16 wiring.
It powers the pullup resistor so the PAD1,2,3 are 0-5V signals.

Re: D14-D16 wiring.
it's not 0-5V but 0 or 5V, am I right ?

Re: D14-D16 wiring.
0 or 5v is what I'm seeing on PAD 1. Could I remove R58 and just use that circuit as an on/off connecting
PAD 1 to SPR3 to turn my fan relay on or off depending on what parameters I set in Tuner Studio or
would that not work?? I have V3.57 so no proto board and would like to use what exists.
Again many thanks.

Re: D14-D16 wiring.
The diodes are available as programmable on/off outputs, so yes they could be used for switching a relay as long as the relevant transistor is up to it and they aren't being used for anything else.
