What is the difference between the digital and analogue Bartech units?

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,

Have a look at http://www.steadicam...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
