Control Mechanism Integrated into Advanced Pan & Tilt Systems

Capture Systems, designers, developers and manufacturers of advanced modular multi-axial positioners, have developed Cap-Track an integrated control mechanism, designed as an interface between user applications and Pan/Tilt systems.

The internal Cap-Track controller collects data, summarizes values, sends a command to the current amplifier to conduct a motion, and then verifies the error and adapts a new command. The sequence operates at between 50Hz to 100Hz.

The current amplifier pushes current to the motors in a fixed or changing PWM frequency, which is dependent on system requirements and the feedback mechanism. The feedback mechanism utilizes potentiometers, resolvers or encoders in order to close speed and position loops.

Cap-Track works in unison with the Capture Control Panel. This is an integrated software platform for Capture Systems’ operating systems, which provides a complete environment for testing, integration and usage of Capture Systems applications.

Advantages include: joystick control enabling simple and precise gimbal movement, easy communication protocols with Capture Systems Pan & Tilt systems, and a dedicated user interface characterized by client specifications.

Capture Systems pedestals support the following communication protocols:

• Ethernet-TCP 10/100
• RS-232
• RS-422
• RS-485 / Pelco – D
• Onvif (under development).
