Air output (optional outputs)
In the attached diagram there are a trio of pins (far right side) marked as (Optional) and "duplicate header pins"
They are present on my mg3, but I'm wondering if they need any special handling compared to the normal air-assist output? In particular, does the "optional" mean I have to do something to make them active?
They appear to far better suit the relay I want to use, but I'm wondering...
What voltage (and/or what signal) is PWM out? Can I use it to power the 5v input for my SSR?
Also, though less critical as (IIRC) it's switchable, is Air on active low or active high?
FWIW, I'm looking at using a direct 240V SSR to switch the air pump rather than switching a solenoid (https://core-electronics.com.au/1-channel-solid-state-relay-module.html)
Any thoughts on the wisdom or otherwise of this?
The one I have is an active low, with inputs for 5V, GND, and signal (on the control side) and two input for AC power.
Please is anyone can help that'd be awesome.

I'll note: I now know what the PWM is - at least if I understand correctly is the switching signal for the laser - at a guess by Pulse Width Modulation.
So it won't work for what I want. Oh well. Any other good sources for a 5V signal?
