Premium Members Tony Reyes Posted May 21, 2012 Premium Members Report Share Posted May 21, 2012 Just wanting to check in with everyone here before I drop $5,000. I'm wanting to buy my friends Bartech and M-one (both are analogue) then buy a G-zoom new. My question is, does it matter that the Bartech and M-one are analogue? Do they have any issues together? Any specific cables I need? I'm putting this on a Master Series. To the people that have this setup, any complaints? Do you feel like there is something better? General question: What is the difference between the digital and analogue Bartech units? Quote Link to comment Share on other sites More sharing options...
Premium Members Marc Alfonso Posted May 21, 2012 Premium Members Report Share Posted May 21, 2012 The analog Bartech works with the G Zoom. The digital Bartech will not work with the G-Zoom as there is no analog input to the BDR. The difference between the Analog and Digital Bartech receivers are the types of motors that each work with. The Analog Bartech works with motors such as the M-One analog and Heden M26P that have a potentiometer that detects the position on the output shaft of the motor. These motors use a 5 pin Lemo connector. See this article: Potentiometer The Digital Bartech works with most industry standard lens motors such as Heden, Preston, Scorpio and M-One Digital. These use use Digital Optical Shaft Encoders connected to the Motor itself that generate Digital pulses that are used to derive the position of the output gear of the motor and this is used by the Digital feedback circuit in the receiver to position the motor. These motors have a 7 pin Lemo connector on them. Here is a great article: Optical Encoder Hope this helps, Marc Quote Link to comment Share on other sites More sharing options...
Moderators Louis Puli SOC Posted May 22, 2012 Moderators Report Share Posted May 22, 2012 Hi Tony Have a look at http://www.steadicamforum.com/index.php?showtopic=13341 I wrote about the BDR digital receiver .Marc covered all of the main areas between the analogue / Digital . Either way both systems will hold you in good sted and upgradable in the future. All the best Louis Puli Quote Link to comment Share on other sites More sharing options...
Premium Members Tony Reyes Posted May 22, 2012 Author Premium Members Report Share Posted May 22, 2012 Thanks for all the info Marc. I will definitely be checking out those links. You are very knowledgable. I talked to Erik at G-zoom and he confirmed that the analogue setup will work fine. I went ahead and ordered everything, Bartech, M-one, and G-zoom. Thanks, Tony Quote Link to comment Share on other sites More sharing options...
Premium Members Tony Reyes Posted May 22, 2012 Author Premium Members Report Share Posted May 22, 2012 Thanks guys, just thought of something. I need to acquire the power cable for this thing! A friend of mine mentioned that Bartech sold power cables but I didn't see any on their site under "Accessories." It will be on a Master Series. Simple 2-pin Lemo power cables? Can I simply have this made? Quote Link to comment Share on other sites More sharing options...
Premium Members Tony Reyes Posted May 22, 2012 Author Premium Members Report Share Posted May 22, 2012 Just found it! The cabling is under "price list." Quote Link to comment Share on other sites More sharing options...
