BYE Hanging and Disconnecting

[bhamilton700]

Hi, 

I am evaluating a 16 foot cable with BYE 3.1.16 Premium that I am using with a Canon 60DA.  I first tried it with Celestron's CPWI software during the day for a 40 minute session and also used another USB cable to the hand controller.  It was fine with around 60 photos.

Last night I used the same 16 foot cable to my camera but this time used wireless control for CPWI.  It was a 2.5 hour session (mostly Live View) with around 30 photos. BYE hung on me 3 times and also disconnected a few times.

Any ideas on what could be causing this issue?

Thanks

Bryan

Bryan,

You talk about cabled and wireless connections. I assume that you are cabled to the camera and using wireless communication from the PC to the mount via the CPWI driver. I would not expect loss of comms with the mount to hang BYE.

Running LiveView for an extended period can cause the camera to shut down without warning to prevent damage to the sensor caused by overheating. LiveView may also shut down automatically after 30 minutes of continuous use. Also, the Canon SDK does not react well to even momentary communication glitches between the camera and the PC. Glitches can cause unrecoverable errors that can cause BYE to hang or crash. A 16 foot USB cable is right at the length limit for USB 2.0. You may want to use two shorter cables with one of them being an Active Extension cable and both of them being quality cables.

Live for 2.5 hours is most likely the root cause.  DSLR are *not* meant to say in live view for extended period of time. The camera has built-in thermal protection that will shutdown the camera and I suspect this is cause the issue; the camera is shutting down and BYE looses it's connection to the camera abruptly. You probably need to change your workflow and if this was my camera I would never leave it with live view activated for more that 5 to 10 minutes at a time.  Keep us posted.

Thanks for all your help on this.  Yes I am using wireless for CPWI and it's the camera cable.

I did another session with limited use of LiveView and had no problems at all.  I think the cable is fine and that it was the LV.  I think the cable is good quality and it's a Pearstone with a ferrite bead in it.

Can overdoing LiveView cause a "speck" to appear in a photo?  Looks like I got one in my photo of the moon the other night although I wasn't able to image it again over the weekend.  I had to test with M3 instead and it was blurry.

Yes, live view has a huge impact on the sensor temperature; a hot sensor will introduce a lot of specks/noise.
