SMAKN relay support - clicks on, but not off

[khobar]

I was very excited to see SMAKN relay support added, and I just updated my version of BYN. Unfortunately, while the relay does trigger "ON", it never triggers, "OFF" and BYN hangs. 

Any ideas what could be going wrong? Is there a log file I could send? Is there any diagnostics I can run to help figure it out?

Thanks very much!

Hello! I just wanted to let you know I got the cable figured out and that the SMAKN is now working just fine.

Thanks for making the change!

All the best to you and yours,

It appears that you are the first user of the SMAKN LCUS-1 cable since it was first added in 2018. In a note at the time the devs said that they added support via some sort of API call but were unable to test because they did not have the relay device.

As mentioned above, I could never test the SMAKN cable and support was never added officially as a result and never confirmed.

Here is the said post.

 

There are many other cables that I have been able to test and support.

Based on this post I'm not sending the correct sequence to close the shutter.

I'll try to upload a new version in the pre-release section later tonight.

No promises and if this is not working, I won't be able to do anything else for now.

Wow - thank you for the quick reply!

I noticed I'd asked about this back in 2018, but I then got the KMTronic board and, of course, that works perfectly. But I've since acquired a second D5100 and, well, I had this SMAKN relay board and a couple of HID relay boards and figured why not give them a go.

I did test the board on a Windows 7 laptop and was able to get it to work with the sequence you linked to:

Open the USB switch: A0 01 01 A2
Close USB Switch: A0 01 00 A1

Anyway, thanks again. I can test, if that would help!

I have downloaded and am now installing. Will let you know ASAP!!! Thanks very much. Fingers crossed!

[khobar]

Thank you again. 

I was able to download the new version.

I was able to take a 45 second image - the relay triggered on, then triggered off successfully.

BUT - for some reason, when I attempted to take a second image, the relay triggered, but the camera did not. That doesn't seem like it would be an issue with BYN I don't think. I will have to do further testing with the other cable.

Unless you happen to know what's going on?

I am very grateful for your help. Cheers!

I don't know.

I will test my other D5100.

This one just arrived today, from Ebay. It seems to work, but who knows.

I'll keep you posted.

It looks like I had a duff cable between the relay output and camera. Using the other relay board, this "new" cam works fine. Using the DC-2 cable from the other relay board, this "new" cam also works fine.

It's only three wires - how did I go wrong?  

Cheers!
