I've got a Heden carat that I've been using problem free for some time with Alexas and various other cameras.
I can't for the life of me get it to run an epic however. I've got the run cable that comes from Heden with the 3 bnc ends and have also had a cable made to Heden specs from the local cable guru that goes direct to the sync port on an epic.
It turns out that the heden specs AND the cable straight from heden had the wrong polarity at the epic end to make it run.
I got that fixed and tried to make it work, but still can't make the heden run the dragon.
When tested with a voltmeter, the output voltage is identical to a remote run cable supplied with the kit that works fine.
Cable is plugged into sync port, camera input field says "general purpose in", brain gpi high- "record: start", brain gpi low- "record: stop" and camera input says "sync out".
These settings I know are currently working for a friend on another production with a heden, although it is the first time he has managed to run a red with his heden. Are there other settings in another menu that affect the running of the camera?
I would ask heden directly but they have the worst customer service I have ever encountered and have never yet responded to a single email.
