| Controller Options Microprocessor control - for photometry and general purpose illumination the Optoscan can be controlled from a front panel keypad and display (or via a PC serial port using the emulator program provided). This control unit allows a full range of built-in stepwise and scanning illumination options, and also provides the timing signals necessary to drive Cairn photometry modules (if appropriate). Microprocessor control is recommended for combined photometry and imaging applications. Some software packages can pre-program the Optoscan system using an RS232 link and then use a parallel port for real-time control. This effectively operates the Optoscan as an eight-position filter changer, with precise control over the centre wavelength and bandwidth of each filter position. A big advantage of the microprocessor controller is that the Optoscan can be run independently of the software. Direct control - the Optoscan can also be controlled directly using analogue signals. To facilitate this we offer a complete package including a DAC card, power supply, cables, software drivers and dll library. This package works seamlessly with most commercial imaging packages to provide completely flexible illumination control in both acquisition and scan modes. USB 2.0 control - the most powerful and cheapest way to control the Optoscan is via our embedded USB controller. This recently added interface is the default for new systems and drivers for most software applications are currently being updated to support this option. |
