ZWO ASI1600MM Pro Camera
MacOS 10.13.2
INDI Server Version 2.5.2 (1.5.0)
INDI Control Panel Version 2.3 (53)
Setting Expose to 1.0 seconds in the Control Panel results in the timer counting down and then reporting
ERROR 1569.890499 sec : ASIGetDataAfterExp (1x1 #1 channels) error (13)
No image is transferred.
Other applications using the INDI Server do not complete downloads, KStars, and PHD2.

Settings via the INDI Control Panel look like this camera is not correctly supported.
The Camera WIDTH and HEIGHT settings give an error indicating the range is 0 to 0.
Similarly for binning. Pixel size is not reported. Following is the output from indi_getprop

Where are you getting the INDI server version from?

Cloudmakers

Did you try using KStars internal INDI server? Settings --> INDI. Then restart KStars after that and try again.

KStars Version 2.8.9

Hmmm. I do not see any menu entry for internal INDI server under Settings.
There is Settings-->Toolbars Shown-->INDI Toolbar

Did you try this?

I was not able to find that window but I can now run the camera.
KStars Toggle ECOS on. Start the INDI server. I was able to record individual images from the INDI control panel in ECOS and run in video mode!
The current sensor size and pixel size is reported with this server.
It looks like the internal INDI server in ECOS supports the ZWO ASI1600MM Pro, but this is internal to KStars/ECOS.
What about other applications depending upon an INDI server such as PHD2 or the Cloudmakers INDI control panel?

The window in my screenshot was in Ekos where you set up your profile before you start the indiserver.

To answer your question once you start an indiserver with your devices, it doesn’t matter what program is serving them up, it will work with other clients.

Also note that the cloud makers indiserver program and KStars internal indiserver are built from the same source code mostly, so give them some time and they will update it

I am in good shape now. Ekos works.
Using the INDI server in EKOS I can see correct values for the camera being reported using indi_getprop.
