Position-Electronics 8-channel Mark II
Description
The THOMA-Position-Electronics is a measuring and analyzing circuit for 8 axes of studio equipment.
The standard version is capable to contrl the high resolution encoders with up to 3.6Mio steps/360°
The 32 Bit Microprocessor delivers a delay of 1ms betqween data-capturing and data output
Effect of parameters for the interface-protocol by dialogue between host and electronics:
- address of delay-times
- Assotiation of data-bloc to camera-number
- Adjustment of Baud-Rates (9600 bis 115200)
- Adjustment of blocfrequencies (50, 60, 100, 120Hz)
- Deinition of number of axes
If a time-code-generator is plugged to the RS 232 interface, a time-code for each data-bloc can be provided.
