Serial cable connection Canon 450D replacement

[frenchbaz1]

Hi

I have used BYEOS for around 10 years. I recently started using my telescope again after a few years. First couple of sessions OK and then could not connect to any astrophotography software (dslr focus etc). Checked through all connections and believe it is serial connector. I am struggling to find someone who can supply a new connector and cable and I am rubbish at soldering! . One thing that has come up is the KMTronic USB Relay Board. Will this solution work with BYEOS?

thanks

The 450 does NOT need a serial cable.  All you need is the camera supplied USB cable with the 450D.

Hi

The canon camera is a modded 450D rebel from around 2012 so the older model which needs a serial cable for bulb long exposures.

 

thanks

No, please read the supported camera grid, link in the page footer of the website.

The 450 does NOT need a serial cable for BULB.  It can do BULB over USB just fine.

I used to have a 450D. I have never used a serial cable for BULB exposures. That said, if you run both a USB cable AND a DSUSB serial cable between the PC and the camera, you can configure BYE to use the serial DSUSB cable for bulb exposures.

The key is that you need two cables. The DSUSB cable runs between a USB port on the PC to the remote shutter jack on the camera. This cable only controls the shutter for BULB exposures. The second cable, which runs between a USB port on the PC to the USB jack on the camera and controls everything else (like connecting BYE to the camera, reading and writing camera settings, taking non-BULB exposures, downloading images).

Hello  again

Thank you for your prompt relevant answers. If I am right it seems that things have changed in the  years that I have not been using my telescope/canon set up. When I started I dont think there was a DSUSB solution for the long exposure bulb problem with the Canon, therefore I needed a serial cable.

Looking at the table as suggested by Guylain it would now appear that the best solution is a DSUSB cable.

Sorry to be a nuisance but could you confirm this before I purchase the DSUSB cable.

Thanks again for your help, using my telescope again in this lockdown situation is proving a great anxiety relief.

No, this is wrong.  DO NOT purchase a DSUSB cable.  You do NOT need any other cable other than the regular USB cable that came with the camera.

This is my 3rd time saying that all you need with the 450D is the camera supplied USB cable. I don't know how to make this more clearer.

OK Chaps

I have taken on board you advice. I have updated my version of BYEOS to the latest and attempted to connect camera with usb. First got no digic drivers, reinstalled after getting rid of old versions of BYEOS. Have drivers but get message 'Canon digital drivers not found reinstall software'. If try without camera get same message. I believe therefore that camera is not connecting to PC. Can see camera through File explorer and view memory card but nothing else.  My thoughts (not always relevant) are USB cable not working or camera problem.

any thoughts on way forward gratefully accepted.

thanks for your time

Barry,

If you are installing BYE 3.1.18, you may be seeing a problem with the installer that has been noted in several other posts where after a seemingly successful install, that the drivers screen is empty. Sometimes the fix is to re-install BYE to a new folder. Other times it is to install the version 3.2.0 pre-release which uses a different installation program.

Also, at the point where the drivers should be displayed, the program has not yet tried to detect or connect to your camera, so you should get the same message even if the camera is not connected.

You are seeing a bad installation, not a faulty camera or cable.

If you can see the camera in File Explorer, then the USB cable and camera must be working to some extent.

Hello

Success !!!! or nearly? Loaded v2 on my Windows 10 desktop and it worked perfectly. Next problem is my astro laptop is XP and therefore 32 bit windows. So I will attempt to reinstall 3.1.18 and try again.  Or I can steal my wifes laptop which is Windows 10 . I know why I was sure I needed a serial as my previous camera was a 350D. All those years fiddling with two cables😒.

Looking forward  to going out again in my orange tinted urban skies.

Thanks for all your help.

Sorry, what do you main by "Loaded v2 on my Windows 10 desktop and it worked perfectly". Do you mean BYE 3.2.0 RC?

BYE is not a 64-bit application and so it should install and run correctly on any system 32-bit or 64-bit that has the pre-requisite software. You may need to install .NET 4.0 on your XP system.
