Suddeny getting disconnects and crashes log attached

[telfish]

Having reformatted my HD and re installed everything I am now getting disconnects at random. There is an sdk error generated within the log, not sure what that means.

 

Camera will connect then at random intervals disconnect, on trying to connect again  BYeos will sometime just crash. Have deleted and re installed. Camera is set to never shut down and is running on a mains adapter. Camera is connected direct and not through a hub.

 

Any help appreciated.

I'm glad that I clicked on Telfish's post concerning random disconnects between camera and computer.  My setup includes a 16-foot active USB2 cable out to my pier (no hub involved) and then whatever USB2 cable combination that will reach the camera's input jack. Until recently, I had no problems, but now with temperatures well below 32 degrees Fahrenheit, my outdoor connections break and make when either a slew the scope to a different position and/or the gusty wind blows. I suspect that the stiffness of the cables due to the low temperature and maybe some uneven contraction of metal USB cable connectors are the culprits. The tiny connector at the camera end of the chain of cables has to support a fair amount of weight for its size. I'm guessing that that is my weakest and most vulnerable connection.  Has anyone found a six-foot long USB cable designed specifically for the Canon 500D (Rebel T1i) that is reliable? I will look into the brand Tripp mentioned by Cystokid.

Bob,

 

I have used a generic USB (micro USB Type B male to USB Type A male) cable in place of the Canon-supplied cable to operate both my XS and T5i cameras, so at least for my cameras the supplied-cable is not Canon-specific and any good quality cable can be used in its place.

Thanks, Rick. In addition to replacing my Canon-supplied short USB cable, I'm going to try rigging a strain relief for the Type B micro end of the cable. By the way, is there any great advantage to upgrading my RebelT1i to a T5i? I would guess that a Rebel camera body is still a Rebel camera body as far as astrophotography is concerned? 

[astroman133]

Off the top of my head...The T5i has a different processor and sensor, so it may have different characteristics (and hopefully lower noise).  The T5i also has an articulated LCD display so you don't have to bend your neck at an unnatural angle to see the display.  There may also be different ISO values and JPG file size options.  However basic operation with BYE is still the same.

I was having the same issues with a new T3i and a fresh BYE download last week.  Imaged M3 and several other items without issue and then started locking up in the download process.  I was able to switch from the USB3 to the USB-2 and it worked without issue. 

 

Does Cannon make a wireless or Bluetooth camera that would allow BYE to operate wirelessly without USB?

 

Thank you for the help on my first visit to the forum...

The latest Canon DSLRs - 6D and 70D - do have integrated WiFi, and the EyeFi SD Card can offer the same for older SD-based DSLRs.  However, the WiFi Range and Speed are less than commonly experienced by tablets and laptops (with their correspondingly larger antennas), and WiFi takes a toll on the Battery Life.

Bluetooth, with it's significantly shorter range and much lower throughput, wouldn't be useful for much but as a Wireless Remote Shutter Trigger.

I had the exact same issue! Guylain is right---this is likely due to your cables. I went out and purchased two 16' cables by Tripp. These are very well manufactured and not cheap imports! I also have a separate USB 2.0 hub (powered) for each cable--one for BYE and Skytools 3 and one just for my SSAG. The system now works flawlessly. Make sure you plug your USB cable into a 2.0 and NOT a 3.0 port, too.

Bid I would have obtained hi quality cables and listened to all the good advice I got here, it would have saved me MONTHS of frustration.....

Hi Terry,

 

ALL camera disconnect are always hardware related, not software.  This issue is between your computer/cable/usb hub/camera.  We need to find the root cause there.

 

How long is your USB cable?

I have tried through a powered hub and via an active USB lead which is about 16 feet long. Both used to work fine, now both are having disconnect issues.

The issue is still hardware... I guarantee you that.

 

Get rid of all those cable and plug the camera directly in the computer with a single USB cable < 6 feet and work your way up... eventually you will find the culprit.

 

The Canon SDK is extremely sensitive, if the connection between the camera and the computer is temporarily interrupted, even if it's only for 1 millisecond, it will fire a camera disconnect event.

 

This will also occur if the USB cable is saturated with data at any given time.  So if you have -all- your devices connected to a hub and the hub into a single usb port on the computer sooner or later the cable will be over saturated with data and the camera will disconnect.  Almost -all- reported camera disconnect falls into this category <_>

Thanks G.

 

Will try that I think you are right because I am getting com port loss with my focuser as well, so somewhere I have a bad connection/component.

 

I will find it!

Keep us posted on your progress trying to find the culprit Terry.

I think I may have found the culprit. The active usb lead had a loose socket. So when the scope moved the connection from the camera lead disconnected momentarily. That was enough to cause the issue.

 

I went back to a longer standard lead into the powered hub and yesterday it kept connected for 24 hours including 6 hours of imaging.

 

Thanks for the help as usual Guy.
