I see this in the log file
`iOptron CEM120\nPlease ensure remote device name corresponds to actual device name`

But you are using a CEM 40?

The CEM 60 and the 120 are supposed to connect direct to a PC using a special serial to USB cable, connected to the rs232 port on the mounts, not via direct USB, the CEM 40 is different..

I can connect to my CEM120 via direct USB. Seems to work fine.

If the CEM40 has the same serial command set as other mounts (good chance it does). Then in theory you could just add it to the models map here
github.com/indilib/indi/blob/master/libi.../ioptronv3driver.cpp
Actually you'll also need to add an entry to the drivers.xml
Then rebuild indi locally and test it.

Hi.

Today I got my CEM40 to.
With the direct USB-Connection I can connect to the Mount (first I have to plug it in the running Computer and than switch the Mount on).
I can connect with the iOptronV3-Driver. But it did not work full.
In this Image you can see the problems. The connection is opened but the communication is not working completely.

It seems there are some issues with the response-data from the Mount. But I'm not smart enough for programming this stuff.

Greetings
Bernd

Thank you.
I hoped, I could use the full equipment next weekend. ;-)
But I think, I have to work with Windows for this first tour.

Greetings.

Hi.

Just visted the telescope-section from INDI-Lib on GitHub . And found the following:

I wonder, how I can install this driver. I can't find this one in my kstars.

Greetings
Bernd

Oh nice! Will test this with my CEM60 :D

You either have to update to the nightly builds or compile yourself (that's what I do)

(that's for the plain INDI stuff - don't know about the Stellarmate though)

I dont use StellarMate. But in the Nightly-Builds the Drivers are not net included. ;-)
Do you have a link to a little HowTo for build and compile it by myself? The environment should be installed. A friend of mine compiled a focuser-driver that he programmed.

Well, as the check-in from Jasem had be at 2am indeed the nightly builds might not yet be up to date :D
Compiling is basically as easy as calling cmake and make, as described in the readme (I think). It's more about installing without messing up the system packages.
I'm therefore creating real packages with a build script - but I'm using Tumbleweed (RPM based), so that wouldn't help you too much I'm afraid...
