F3: HELP NEEDED - Sony F3 with a Video Devices PIX-E5 recorder

For the F3 users ...pls help. Just got my hands on a PIX E5 recorder. I cannot get it to record on 50 or 60P with Prores 444. No matter what settings i cannot get more than 25/30p on 444 prores. I get 50/60p but only on 422 codec flavors. Any special settings to get Prores 444 with 50p ?
There's a good chance ProRes 444 may max out at 30p...maybe check the manual if you don't receive another answer.
