• Manufacturer: ETC-unknow

an displayed position on the monitor(DXn,DYn) is;
two points of the touch panel on the display monitor, and store them in the host system. Second
of all, obtain the constant values of CX and CY from Eq.(A) and (B), and store them in the host
systemwith DXa and DYa.
(DXn,DYn) by getting the pressed data(Xn,Yn) and utilizing Eq.(C) and (D) while in ordinary
operation. User Calibration should be done whenever you press the touch panel.
(2) Stop Mode
In the case of setting Stop Mode on, it becomes in low power consumption state when not
pressing the touch panel or not sending any commands to it for more than 30 seconds. During
the state, no serial command is accepted. Sending Reset command or feeding a signal to
SBSCAN terminal of the controller in low power consumption state make the controller resume.
In the case of setting Stop Mode off, reading the reference voltages of Auto Calibration is made
only when powering on or sending Reset command.
(3) Mouse Emulation
PC/AT of IBM or IBM compatible computers and our controllers. Those drivers enable
you to utilize the touch panel like a mouse on your system.
We are providing device drivers as follows;
Serial Communication (CRS1-656)
PS/2 Communication (CRS1-685)
Gunze Electronics USA co. provides several device drivers for mouse emulation with
Stop Mode is a low power consumption mode that the touch panel controller is providing.
Consequently, the relationship between an arbitrary position on the touch panel(Xn,Yn) and
With the execution of Use Calibration, first of all, get the data Xa,Ya,Xb,Yb by pressing
After all of those processes, you can obtain accurate pressed positions on the display monitor
