Anyone doing anything for the Optec Gemini? It operates over both serial and ethernet connections.

Bump - I seem to have everything else working with my rig including control of the Paramount. I just can't control the Optec Gemini. I'd be happy with just the focuser control for now. Any advice on how I might get this working with indi/Ekos?

Seems like the focuser part is already implemented in INDI via FocusLynx driver .

Hmm. Gave that a try in various configurations. I don't see any way to specifically configure for a Gemini. Regardless I always get the same response:
DEBUG   37.951111 sec   : [FocusLynx] CMD (<F1HELLO>)
ERROR   39.953177 sec   : [FocusLynx] TTY error: Timeout error
INFO    39.953205 sec   : [FocusLynx] Error retreiving data from FocusLynx, please ensure FocusLynx controller is powered and the port is correct.

I'm able to connect to the same port using TheSkyX (on Linux) with no problem. stty shows the port speed as 9600. I tried that and 19200 - same outcome.

EDIT: using 115200 baudrate seems to allow a connection. Testing....

I'm able to connect now but still not working. I"ve tried selecting various device types including Optec TCF-Lynx 2/3 and TCF-S "Classic Converted". I get similar results in each case:

Dear Schwim.
I've looked at the documentation. Yes, the working way of the Gemini is based on the same kind of syntax as the FocusLynx HUB, but unfortunately, one big difference is a "transaction id" in the string not present in FocusLynx hub. Using a Transaction ID allows multi-threaded client (From page 5 of the "Gemini Command Reference, Revision 2.1")
That means you couldn't use as it is the Focuslynx driver even for focusing only. Now I'm working on some changes on the drivers to add full support for both focus driving and network support (With Optec support as a timeout issue is present on network connection), but I look too difficult(for me :-( ) to integrate the Gemini rotator/focuser on it and I think a new driver has to be written for that, based on the existing one for FocusLynx.
My proposal, if you're not in a hurry, is to let me finish the new version of FocusLynx one and published it (I hope for the end of August. Then we use it as base' driver for your device.
Do you coding and could do it? OR shall we have look to work on it?
@Jasem: The main difference is the transaction ID present in command string and in Gemini's acknowledge.
If not in hurry I could work on it, but as written behind, first I should publish a new FocusLynx version, then I could work on Gemini one. That means nothing for first testing before the first week on October, depending on my work and family load.
One question Ekos related. For Ekos Focuser and rotator have to be seen as two devices, havn't it? If yes I suppose we have to use the same trick as FocusLynx's driver with two main objects on it.

@both: let me know what you think of my proposal.

Best regards and clear sky.

Philippe,

Thanks for looking into this! I will check if I can create the rotator/focuser driver for this device, need to investigate a few issues.

@schwim: Can you make your device accessible to me? If it is on RPI3, I need SSH connection. You need to email me details to access it to develop a driver.

Thanks for looking into this guys!

Jasem - I will spin up a VM and connect the gemini in to it and get you access. Give me a bit to get that running.

VM spun up. Latest indi and kstars/ekos installed and operating. I sent you an email (I think). Need to know who/where to let in.
