Darko... Picloc-3X is programmed primarily with PiclocToolz, running on a Windows PC/Laptop/Netbook, running Windows XP/7 (both 32 and 64 bit), and soon even Windows 8.
It offers very fast real time visualization of what you're changing. No Read/Write buttons to press each time you make an adjustment.
It is a very transparent interface.
A lot of customers only use PiclocToolz, no JetiBox ( especially non-Europeans ).
The Jetibox is used for programming at the field... either connected straight to Picloc, or else wirelessly through the Jeti Duplex link ( if you are using a Jeti RMK-2 for example ... )
This way it can display telemetry data also to the cameraman's TX.
It's quite a neat feature, and I hope to be improving it heavily in the future, as well as adding Graupner HOTT compatibility.
Edit.... no I havn't seen your mail with reservation... as soon as I'll find it, I'll acknowledge you.
