HELP! Blackmagic HDMI->HDSDI Mini-Converter
Posted 29 April 2011 - 10:43 PM
I'm trying to power a Blackmagic HDMI->SDI mini-converter off of my Zephyr. I had a cable made to supply power from the sled, but the dang thing won't power up. It works fine with the AC adapter, and I know the 12v outs on the sled work fine. Anyone know what could be wrong? I thought I heard somewhere that the BM converters MUST have regulated 12v to work properly. Can anyone confirm this, or provide me with some assistance?

is either you get a lemo to 12v regulator to DC out, or you can purchase one of the V mount battery plate thingy
they can regulate a v mount battery on top and output 5, 7.2 or 12v for your devices, i always hook that up and place it on my top stage, good excuse to increase my sled weight for stability as well.
it is a good way to mount the camwave if you are using DSLRs, you get a v mount slot supposed by 15mm rods. and is affordable.

I recently got my (heavy duty) black magic sdi downconverter. For now I thought of using a common D-Tap to power it but I measured that one of my batteries got up to 15Volts.
So I'm fairly concerned about that method - Now I heard the heavy dutys were supposed to work with a bit more than just 12V? Or should I consider another power supply?
Maybe a customized 3pin LEMO to DC cable? Might the Aux Power off the sled go beyond 12V? (Having an old Artemis EFP)
I'll appreciate your help

There is also a battery converter version available that has the same heavy duty case plus inetrnal battery but is cheaper, inexplicably. Same price as the "classic" converter. That is also 12-31v.

Blackmagic is a little erratic about their power conversion--it seems weird that some of their mini-convertors have upgraded high-voltage capability and others don't.
Meanwhile: AJA still has some units that are 5v, and others that are fine with higher voltage. For the record, Decimators all take the voltage that a hot battery can dish out.

Sorry, I didn't point that out but didn't want to open another thread.
OK yeah, the downconverter is indeed 12v. I didn't notice that you described it as such. This is after all a thread about HDMI to SDI convertors.
Excuse my probably dumb question but how would I test it and not destroying it?
Only way to distinguish is the serial number or by testing.
