MicrIO XH100 Crosshair Generator

The Micrio XH100 crosshair generator superimposes an adjustable crosshair on a NSTC video signal. It is compact and cost effective. All components are on a 1.8" by 2.3" circuit board. Video connections are made through RCA coax connectors. The cursor position is digitally controlled and will remain in position regardless of temperature changes.

The position of the crosshair is adjusted by a single knob. Pressing the knob once selects the vertical cursor and causes it to flash. Rotating the knob moves the cursor to the desired position. Pressing the knob a second time selects the horizontal cursor causing it to flash. Rotating the knob moves the cursor to the desired position. Pressing the knob a third time causes the cursors to stop flashing and returns the crosshair generator to normal mode. In normal mode rotating the knob will not move the cursors. After 4 seconds delay the current settings are saved in permanent memory. After a power cycle the cursor will return to the saved position.
