My name is Ron and I live in Celina, Texas. Been an imager for a long time using ACP. I am happy to report the Pat M's latest Github plays well with ACP as the client. Mount and Dome danced together for the first time nicely tonight. Version 05.2.3 PDMRotator, PDMShutter, and ASCOM PDMDome0523Setup. I am unclear about the voltage setting in the setup tool. My controller drops to very low voltage when not active (rotator) and unless I set low voltage threshold to something like 5.8 ACP will disconnect from too low voltage. I'll try a different power supply for the rotator..
The Rotator compiled clean. The shutter uploaded but complained of missing items. Now that the Dome itself might actually be ACP-ready chasing down the shutter is next priority. Any obvious gotchas folks know about pass my way. Pat!! I'd love to have a good way to interact with you about this. I did re-up Facebook just for the NexDome group but all my IT friends say to stay away. I'll do what I need to do to get all of this talking well! I'm really excited to have the Dome, find this group, and watch it track objects as a slave to ACP.
Ok, This is the schematics for that part :
On the board picture, R1 is on the right, R2 on the left and R3 in the middle.
You should get about 4V between GND and VPIN (12v /3 = 4v).
Thanks! I'll poke around with my volt ohm meter and see what the story it has to tell. Thanks for the detailed information!!
I see the 3 resistors on the board :
So either one is not properly soldered (things happen as we say) or they are not the proper value.
They should be all 1 mega ohm ( Brown, Black, Green, Gold), or at least all 3 should be the same.
Here is a picture I took when the controller arrived. Where might I look for the resistors? I see the power in (red/black).
Thank you very much! I will do so. The Great news is that the dome/shutter have been working perfectly in unattended automation with ACP as client program. I had set the minimum voltage in settings (0.5.3.2) to 1V.
The voltage shouldn't change between active and non active as it takes the 12V input and run it through a voltage divider using the 3 resistors then feed this to the A0 (analog 0) pin of the Arduino.
5.8V is not normal, it should be around 12V and can drop to 11V or slightly less if the power is a battery.
Can you check the board to make sure all 3 resistors are in place ?
