Pyxis sdi output reverting to 4k output by itself

PostMon Nov 25, 2024 7:12 pm

Hey guys,

I runned into a problem on set the other day. My AC connected everything from cam to monitor on d-tap straight into the battery plate. We had a few hiccup during the day with the d-tap splitter resulting in everything shutting down and powering up again in a matter of seconds. After that happen a few time, the sdi output stopped working altogether. I thought my sdi port blew out so i was pissed and in a rush so we ended testing a few things to see if we had signal coming out of the sdi. It looked dead at the time. Today, since I had time on my hand, I tested it and though about looking if the sdi was still outputting an hd signal or if it was somehow back to 4k (my camera ecosystem is not 4k yet). I guess I am lucky, because it reverted to 4k somehow and seems like the port is fine now.

My question right now is if this could be a safety measure that if the port is about to be blown, the sdi signal revert by itself to an original state or on the contrary if they're is a known issue where the sdi output revert to original state by itself for any other reasons? Should I send it back since it's still 3 weeks old and under warranty or it's really not an issue? I've got another short coming in 2 weeks and would love to shoot on my pyxis instead of my OG ursa. :)

Thanks for output!

Only use dtap splitters. Never the battery plate. Get a Dtap splitter with a switch or Dtap cable switch made.

This has happened to me too twice.
No idea why.

Hmm...I doubt this is hardware-related and could be fixed in software. Let us look into it.

That’s a relief, thanks.

Everything was on a d-tap splitter, but I feel they were loose connections either on the d-tap splitter or between the splitter and the battery plate. I look into d-tap splitter with switch thanks.
