EOS Ra connection problems

[markyscott]

Hi - I’m having a problem connection my EOS Ra with BackyardEOS.  The camera connects to my Windows 10 laptop with the USB-C 3.1 cable that came with the camera and the EOS Ra utility launches successfully.  I can see the camera listed on the device manager and can operate the camera remotely with the EOS utility.  However, the camera is not recognized by BackyardEOS.  When I click on “Connect’, the menu is disabled for a few seconds, then reappears, but the camera is not connected.  Any suggestions?

Thanks

Scott,

You need to disconnect the EOS Utility from the camera. You also need to ensure that the EOS Utility does not automatically connect to the camera the next time you plug the camera into the PC.

Only one application can connect to camera at a time.  May 100% sure EOS Utility is disconnected from the camera before trying to connect it to BackyardEOS.  In fact, I would make sure EOS Utility is not running, not even in the background, and as mentioned above, I would also make sure EOS Utility is not automatically connecting to the camera each time you plug it into the computer.

Thank you - that seems to have worked.  One more question - do you have any recommendation for what cable to use?  The cable that comes with the Ra is only 2’ long and it’s just not long enough to extend between the telescope and the computer.  I’ve tried two other cables - 

1) This USB-C cable.  I’m not sure what type it is - I’m guessing 3.1 or 3.2.  https://www.amazon.com/gp/product/B0832M9WD5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1

2) and this USB-C 2.0 to USB-A.  That one I bought on the advice of a Canon rep.  They told me that USB-C 3.1 can only handle a 4’ cable max.  If I wanted a longer cable, I needed to get at USB-C 2.0 cable.  

Neither work.  The camera will just disconnect after a couple of seconds into the exposure - even with the EOS utility.  It doesn’t seem as though Canon sells a longer cable to use.

I now know more about USB types and protocols than I ever wanted to know, but there you go.

Thanks in advance for your help.

USB3 protocol says up to 9 feet.

Tether Tools has some of the best cables out there. They also have active repeater cables if you need longer reach.
