II will do whatever ypu want to help. What me to sniff the transmission with a logic sniffer? Plug an oscilloscope and chec signal? What can I do?

Hello,
Did you try the INDI driver for Atik filter wheels ? It could be interstereting to test it with your Nautilus one.
If I remember, the Nautilus filter wheel was made by a portuguese company named Brightstar (and then named Nautilus by Orion Telescopes & Binoculars). And they really look like Atik's filter wheels too. So they could be managed by the same drivers.

hi , thank you.
Yes I try every driver availlable on the list, none work.

Do you have seen this thread ? I think that Kaczorek had the same problem as you have.
I'm pretty sure that Orion Nautilus and Brightstar Quantum filter wheels are the same product.

Vincent

I will check this and give feedback
Thank you

So, if you can sniff the protocol and document it well, a driver can be developed.

Hi,
I am willing to learn to do that. What method will work , analysing the usb traffic phisycally by plugging a logic analyzer on the usb data wire spliced, of by a software mean like with wireshark? Sorry , I am willing to do it I just don't know where to start my research.
Thank you
Martin

Is it recognized as an HID device or what? Maybe logic analyzer is too low level now? How about you start with Wireshark and see if you can isolate packets for the different commands. Maybe you can even ask Orion for the protocol itself.

By reading this page :https://www.linuxvoice.com/drive-it-yourself-usb-car-6/

I think wireshark will do the job.
Give me some time to assimilate all theses new stuff and I try to sniff the protocol.
See you soon

Just contacted Orion by email to ask, let see. If not Ill do with wireshark.
Thank you

Ok, for the Quantum filter wheel driver, It don't work. Both are usb to serial tough.
Because it is usb-serial, I use a serial protocol sniffer, I hope I gathered enought information for you to get something out of it.
I launched the windows program .exe, then every time I clicked something I export the gathered data for that action into a log file, then redo the log with another action.
The logs I made are downlodable here : my.pcloud.com/publink/show?code=kZVr287Z...yWmXyeE6pRO6UYHpzary
Let me know if that work or not or if you want something else.
Thank you
Martin

Please make a spreadsheet and in it list the action, the command, and the response received. It appears to be just an ASCII based protocol with nothing complicated so far.
