The Pegasus Astro Pocket Power Box Advanced has an adjustable power outlet, 0, 3, 6, 9, 12 V. Although I can connect to the PPBA just fine, I can't seem to control that adjustable output -- and it used to work. This is how I control my light panel (and for darks). I'm not sure if it works on the Ultimate Power Box V2, so if you find the issue it might need to be applied there as well.
This is on KStars 3.5.3 with the latest matching IndiLib on Ubuntu 20.04 LTS.
I can't seem to get it to output a log. In the Ekos Logs tab, I have INDI and Aux Driver selected (and of course verbose output to a file). I don't get a log in that logs folder when I change PPBA settings. I then tried enabling the To Log File option in the PPBA Options tab. I get a file, but as I change the adjustable voltage output, I get nothing written to it.
Oh, I just saw. Driver Debug checkbox. This is what I got below. What's strange is that ONE TIME when I changed it, the setting stayed. Every other time the setting in the UI immediately turned to Off whenever I changed it. This didn't happen in the field the other night, it just didn't change the brightness of my light panel.
I dug through the car to get my Windows machine, which has the native Pegasus Astro software installed. When I tried that, it also did not change the output of the adj out port (though the voltage I chose in the dropdown would not change like it does in the INDI UI; this is likely just a downstream symptom). I have reported the issue to Pegasus Astro, but they don't think it's a firmware issue. It worked fine just a few weeks ago, and I did update the firmware after that trip.
It looks like something failed in my PPBA: the port is outputting 12.58V regardless of the setting, even with the native software. This isn't an INDI issue after all; the PPBA is likely going to go back for repair. Closing topic!
