Coordinate Orientation for RS232 Communication
Figure 6. Default Touch Coordinate Orientation, RS-232 Communication
When the CTR-502000-SC-RSU-0xR controller is connected to a Surface Capacitive touchscreen with normal wiring, the origin for the coordinate system is located at the bottom left corner of the touch surface. This orientation applies when the controller is communicating via an RS-232 serial port, when controller calibration and scaling features are disabled and when the touchscreen is positioned as shown in the figure above. This is consistent with Elo AccuTouch and IntelliTouch touchscreens.
Coordinate Orientation for USB Communication
Figure 7. Default Touch Coordinate Orientation, USB Communication
When the CTR-502000-SC-RSU-0xR controller is connected to a Surface Capacitive touchscreen with normal wiring, the origin for the coordinate system is located at the top left corner of the touch surface. This orientation applies when the controller is communicating via USB, when controller calibration and scaling features are disabled and when the touchscreen is positioned as shown in the figure above. This orientation complies with section 5.9, "Orientation", of the USB Device Class Definition for Human Interface Devices (HID).
Touch Reporting Speed
Touches are reported at approximately every 25 milliseconds at 9600 baud for serial communication. In USB mode, the interrupt interval is 8 milliseconds.
Time from incidence of touch to the beginning of the coordinate report is typically 18 milliseconds in serial mode.
Minimum touch duration to guarantee a touch report is 37 milliseconds.
Grounded/Ungrounded Operation
The CTR-502000-SC-RSU-0xR controller requires that its power supply be grounded for correct operation. The CTR-502000-SC-RSU-0xR controller will show a deviation in reported touch position if the user touches ground while touching the screen. This deviation is less than 5% of the screen diagonal.
Touch Detect Time
The CTR-502000-SC-RSU-0xR controller will detect a touch within 10 milliseconds.
Untouch Detect Time
The CTR-502000-SC-RSU-0xR controller will detect an untouch within 10 milliseconds.
Linearity
The CTRCTR-502000-SC-RSU-0xR controller, when used with an Elo touch sensor with measured linearity better than 1% will provide overall touch linearity better than 1.5%.
Touch Pressure Dependent Position Change
The CTR-502000-SC-RSU-0xR controller reported touch position will deviate less than 2% of the screen diagonal as the touch varies from 0.3 Newton to 3 Newtons.

Controller Alone
Per EN 6100-4-2 1995. Level 4.
Contact Discharge - 8kV.
Air Discharge – 15kV positive and negative polarity.
ESD impulses applied directly to the pins on P2. The Serial port is tested to simulate ESD impulses applied to the monitor connectors. This is done by applying the ESD impulses to P1 via a 560 ohm resistor and a 10" wire. The pins to be tested in this way are shown in Table 1 - P1 pins for ESD testing.
The USB pins, pins 1,3 and 4 are tested using an ESD generator equipped with a standard finger probe and set to 15kV. The ESD generator is applied to the series A receptacle at the host end of a 1m USB cable, which is plugged into the controller USB series B receptacle. The controller is powered up and grounded.
The controller may not function correctly after applying the discharge, however, it functions without deterioration after reset or recycle of the supply. The ESD tests are conducted with the controller integrated into a monitor with the controller and the ESD generator grounded to the monitor chassis.

The jumper function on the CTR-502000-SC-RSU-0xR controller is enabled by placing a shorting jumper on the jumper header. This function reinitializes the NVRAM with default data on the subsequent power on cycle. The stored serial number is not modified by this function. The jumper header location is shown in Figure 2.
The CTR-502000-SC-RSU-0xR controller has one LED status indicator, D5. At power on the LED blinks once and remains off during the microprocessor's power on self test. During this time the screen must not be touched or grounded in any manner.
For the CTR-502000-SC-RSU-00R, upon completion of self tests, the LED blinks at a rate of once per second. Thereafter, when a touch is detected, the LED lights continuously. When no touch is detected, the controller LED resumes blinking at a rate of once per second. If an error condition is detected, the LED blinks at a rate of four times per second.
For the CTR-502000-SC-RSU-01R, upon completion of self tests, the LED remains dark except while the screen is touched during which time it is illuminated.
