Premium Members Lars Erik Posted May 23, 2006 Premium Members Report Share Posted May 23, 2006 Hello there, Will a Preston FF work on 12v? The camera is a ARRI SR2. Can I get power from the cam if not from the rig? Thanks for any replies. Lars Erik Quote Link to comment Share on other sites More sharing options...

You want to power the MDR, yes? contact assignment for the LEMO 4-pin = 1 = Gnd, 2 = +24, 3 = +12V Quote Link to comment Share on other sites More sharing options...
Premium Members Lars Erik Posted May 23, 2006 Author Premium Members Report Share Posted May 23, 2006 Hello Fred, so a single cable will make the 24v Preston transmitter work on a 12v rig? I own the Steadicam Archer. LE Quote Link to comment Share on other sites More sharing options...
Premium Members Erwin Landau Posted May 24, 2006 Premium Members Report Share Posted May 24, 2006 The MDR-1 (Motor Driver) is rated at 10.5 Volts to 30 Volts DC. The MDR-2 (new Motor Driver) is rated at 10 Volts to 48 Volts DC. (at least mine is) So yes, you can power the MDR with 12 Volts. Fly safe, Erwin Quote Link to comment Share on other sites More sharing options...
Premium Members Matt Petrosky Posted May 24, 2006 Premium Members Report Share Posted May 24, 2006 Didn't the old UHF Preston MDRs (pre-microwave MDR-1) require an external box for 12volts? Maybe I have it backwards and they needed a regulator for 24volts? And as Erwin said... the microwave MDR-1 and the MDR-2 should be fine at 12volts. -Matt Quote Link to comment Share on other sites More sharing options...
Premium Members Erwin Landau Posted May 24, 2006 Premium Members Report Share Posted May 24, 2006 Voltage Converter 12/24 Volt, Part # 4800, $390.- I owned two at one point, never used them and still don't know exactly what they're for... I think I still own the 3 pin to 4 pin Lemo cable... why? I don't know... I checked... yes it's still there. Fly safe, Erwin "No idea...

Premium Members Lars Erik Posted May 24, 2006 Author Premium Members Report Share Posted May 24, 2006 Hey Erwin, sorry for asking a lot of questions. I did a search on the internet, and couldn't find the 3 to 4 pin lemo voltage converter connector you spoke about, can you please let me know where I can find such a cable? Is Nebtek a good place to contact? Thank you very much for your help. Lars Erik Quote Link to comment Share on other sites More sharing options...
