I did not think about saving the logs until later in the process when I connected to the STXL 16200 camera. This time everything functioned normally including the temperature control. I shut down and restarted MaxIm DL and tried the ST2000 again.

The STXL 16200 camera functioned normally and I was able to enter whatever temperature setpoint I wanted.

I restarted MaxIm DL and connected this time to my STXL 16200 camera.

The ST2000 camera functioned completely normally, and I was able to enter whatever temperature setpoint I wanted.

I shut down MaxIm DL and restarted the camera using CCDOps.

I tried shutting down and restarting MaxIm DL and reconnecting to the camera several times with the same results. The cooler was controlling to the default 0.0 Deg C setpoint.

I started up the ST2000 camera in MaxIm DL with no issues except that from the onset, the camera would not accept a temperature setpoint.

Based on what I saw, this seems to be either a problem with MaxIm DL or with the ST2000 camera. I started up the camera indoors last night and got some really strange behavior. I am running MaxIm DL Pro version 6.26, but this problem has been going on since version 6.22 or before. Note that the temperature setpoint was originally -17 Deg C The camera was in guide mode at the time, and the guiding seemed to be normal. From what I can tell, the cooler output was also frozen at 63%. The cooler kept running and cooling, but the temperature setpoint was showing zero. The other night this happened with the ST2000, but rather than try to re-enter the temperature setpoint I just left it alone. Instead, I have to pull the plug on the power. When this happens I can not even disconnect it and shut it down.

If I try to change the temperature setpoint the camera will not accept it, and in most cases the camera will become completely unresponsive.

When this happens, the cooler will suddenly show a 0.0 Deg setpoint even though the cooler has been running and cooling. One of the recurring issues that I have been facing is that the cooler control on one or both cameras will lock up. I will typically run two sessions of MaxIm DL one session for my STXL16200 imaging camera, and the other for my ST2000-XM which I use for guiding. I am not sure if this is a MaxIm DL problem or a camera problem.
