connection issue

[pauls...@gmail.com]

Hi, i have been using PHD2 for 12 years or so (thanks, it is great :) )

Today I installed PHD2 and my mount control software Sitech.exe on a new windows 11 pc.

When I tried to connect to the mount, i got the error attached, which i have never seen before. I can work around it by ensuring the instance of sitech is running before connection, but if it's possible to resolve easily I'd like to do that.

I'm guessing it's Windows 11 trying to protect my life again... :) :)

thanks for any thoughts.

Hi Paul, sorry you're having trouble.  The message indicates that the installation of the SiTech ASCOM driver didn't complete correctly and its COM presence didn't get registered.  Did you see any warnings or errors when you ran the driver installer? You will probably need to use the ASCOM diagnostics tool to see what's wrong.  With your workaround, it sounds like you might be using a free-standing app from SiTech which may not use the ASCOM driver.   Since you're working with a new computer, did you also end up installing the latest version of the ASCOM platform?  That isn't required and might not even be desirable at this point,  I'm just asking. Did you use a software migration tool to build your new computer environment or are you doing all this by hand?

Regards,

Bruce

Hi Paul

I'll offer a quick suggestion but if you have followup questions, you will need to send the PHD logs using the built-in log uploader: https://openphdguiding.org/getting-help/ 

This is not a PHD-specific problem. You need to configure your scitech mount (such as port number, etc.) ASCOM driver. Their ASCOM driver appears to have no option to configure it from within PHD (clicking the wrench icon does nothing) so you will need to use another means provided by SciTech (separate app?) to do this. It may be an issue with the driver, the last version looks new as of November. I tried running ASCOM diagnostics on it and it was unable to bring up the driver

Following up, I noticed the latest SciTech driver switched to TCP as a connection, so that is going to require some additional configuration on the mount side, i'm sure

many thanks Bruce & Brian for replies. I didn't see anything unusal when installing Sitech, in fact it states the error code '0' which apparently means installation was successful.  It's a new win 11 PC and I'm installing manually. I started with the latest ASCOM platform then other client software. There are two new variables for me, one is Win 11 and the other is the Version of Sitech, which I haven't used before. I'll explore things on my dev machine and if I can't work it out I'll post again with logs. I'll try the ASCOM diagnostics on a previous version of Sitech which I currently use in the observatory.

Best wishes

One thing to check with SiTech is whether the new driver is still implemented as an ASCOM driver or if they have silently converted it to be an Alpaca driver.

>>>'ll try the ASCOM diagnostics on a previous version of Sitech which I currently use in the observatory.

you might just try the prior version and see if you can get it to connect. 

I think there's a settings/configuration that needs to be resolved on the new driver, it's just not clear to me how SciTech allows you to configure it

thanks Bruce, the latest Sitech 0.96V installer states that the driver is registered correctly, but I found today that the NINA client will not connect to it either, it shows a COM factory error which is unfortunately generic. I've posted on the Sitech forum, I think it will need the author Dan Gray to take a look. Meanwhile, Sitech version 0.95Z seems to work fine with PHD2 and NINA, so I'll stick with that for the time being.

Thanks to all for help :)

Best wishes

It sounds like you're probably on the right path to getting this resolved.  If you do, it would be good if you could let us know for future reference.

Regards,

Bruce
