Precision CrossLine or Crosshair Generators from MicroImage Video Systems are designed for relative size measuring, positioning and size referencing. The CL8800 series is especially helpful in industrial, metallurgical or forensic applications where comparisons in relative position or size are important.
The CL8800 has four X and four Y moveable lines. The lines can be set to black or white and each line can be turned off or on individually. Lines may be changed from solid to serrated with one of many lines styles. A lock switch is provided for each of the four controls to prevent accidental movement.
Line movement can be set to fully independent, tracking mode or mirror mode with front panel switches. In tracking mode, one control moves the position of both lines (without affecting spacing) and the other sets the spacing between lines by moving only one line. In mirror mode, one control moves the position of both lines (without affecting spacing) and the other sets the spacing between lines by moving one line in each direction (maintaining the center point).
The user may choose between line mode or box mode. In line mode, the lines extend to the full height or width of the screen while in box made, the lines are cropped to form a box. When switching between line and box mode, the line positions do not change.
RS232 remote control and query capability is included on all CL8800 series CrossLine models. The unit may be controlled or queried by a computer RS-232 port. The MicroImage Control Language used for this unit is simple to understand and easy to implement in custom programs, using ASCII characters. Virtually all functions can be controlled by the computer. The computer can also query the CrossLine Generator for line position as well as switch and mode settings.
The CL8800 model incorporates a state of the art digitally generated line system which maximizes precision and repeatability without any internal adjustments. The high quality, sealed, multi-turn optical encoders allow the lines or box to be moved over the entire image area with maximum accuracy. The optical encoders allow a very high degree of precision without any of the jitter commonly associated with multi-turn potentiometer controls. Even after aging several years, the optical encoders maintain their performance and remain free of jitter, while the older potentiometer based technology used by others typically become noisier which appears as additional jitter.
The CL8800 is designed to work with HDMI and DVI-D progressive scan video. The unit will automatically lock to the proper input signal. The CL8800 series models utilize a +12VDC power supply and can be used in mobile applications. Board level, units without controls and other models are available for OEM applications.
