IntelliTouch® 2521 Series Controller (dual touch)
The Elo 2521 controller is a HID-compliant device that can be used for dual-touch applications. IntelliTouch controllers are designed to work specifically with IntelliTouch SAW touchscreens. Building technology with coordinating components enables a much smoother design and user experience.
Works two ways
The 2521 series controller is a 2-touch unit that works through serial interface or via USB. It is a full-speed, self-powered, USB device when USB is used.
Elo’s IntelliTouch controllers are designed and manufactured to work specifically with IntelliTouch SAW touchscreens for optimal performance. The controller maintains a no-touch reference signal. This reference signal is continuously updated to adapt to electronic drift and effects of contamination such as dirt and scratches. The live signal is compared to the reference signal to detect touches.
