MicroTouch ClearTek II TouchPen system extends the input flexibility of MicroTouch ClearTek II capacitive touch screens by supporting both touch and pen input. TouchPen’stethered stylus offers handwriting recognition, signature capture, and on-screen annotation capabilities. It is an excellent solution for applications with densemenus or with detailed images too small to touch with a finger. TouchPen system can be set up in dual mode (pen/finger touch input) or pen-only mode. In dual mode, touch screen accepts touch from both the tethered pen or from a user’s finger for ease of use in amultitude of point-of-sale signature capture applications. In dual mode,while accepting input from the pen, all other input isignored supporting palm rejection in a very sophisticated manner. In pen-only mode, only pen inputs are accepted,making it an ideal solution for applications where unintended touches may create problems. TouchPen system is based on the MicroTouch EX II 3700SP, a serial RS232 controller,which takes advantage of the EX II ASIC electronics platform. EX II 3700SP controller offers a wide operating temperature range, high touch resolution, expanded regulatory approvals, improved ESD and EMI reliability.Adding to its application flexibility, the EX II 3700SP offers the capability to upgrade its firmware, even after installation and deployment.
