Control System
Ventana's control system consists of three major components:
- Main control computer (rack-mounted Pentium 4 running Intel DTEC control software on Redhat linux 7.0) connected to an embedded controller on the vehicle, also running DTEC control software on Redhat linux 7.0.
- Camera control graphical user interface (GUI) and lap controller station and single board computer (SBC) to drive the main camera.
- Toolsled GUI interconnected to the camera lap controller and an SBC to drive the toolsled power controller.
Controls for the camera and the toolsled were developed at MBARI. Communication is achieved by use of local area network (LAN), multiplexed serial port technology, and analog interface. The various signals are driven down the fiber using lasers.
