Product Description
The TSHARC C-Ray Board is a new standard in capacitive touch screen controller technology. It supports serial and
USB communication as well as all manufacturers’ capacitive touch screens regardless of whether or not the screen
includes a back shield.
The C-Ray is a high-performance touch screen controller which, in holding true to Hampshire’s design fundamentals,
utilizes ‘off-the-shelf’ microcontroller technology in conjunction with Hampshire’s proprietary decoding techniques and
device driver software. This virtually eliminates the threat of obsolescence while maintaining the high-performance
and utility standards expected from Hampshire Company.
Hampshire’s own TSHARC device drivers are included with the chip or board solutions. Bill-Of-Materials schematic
drawings and technical support are available for chip applications. Custom and private-labeled hardware and
software products are also available.
Part Number Information
HS12-009C0J-03
The latest firmware revision will be supplied with all TSHARC C-Ray capacitive boards ordered.
Integrating the TSHARC Capacitive Controller
Mounting the Controller
The controller has two .122” diameter (4-40 or 3mm screw) plated mounting holes. Notice the mounting hole closest
to the touch screen connector H4.
THIS STATIC GROUND MOUNT MUST TERMINATE TO A STATIC GROUND
.
Failure to ground the controller will result in poor performance and may eliminate the effectiveness of the on board
static protection. Please refer to Fig. 4.0 for mounting details. For additional details about controller integration,
please contact Hampshire.
For best performance mount the controller:
1)
In such a way to keep the touch screen tail away from high EMI, RFI and power sources.
2)
“In line” with the touch screen tail limiting the number and severity of any bends or folds in the touch screen
tail.
Contact your touch screen manufacturer to determine any touch screen manufacturer’s mounting
specifications.
3)
In a way to insure that you are using a communication cable with adequate shielding which is located away
from high EMI, RFI radiating system components.
4)
To shield the controller and/or the touch screen from EMI / RFI noise in cases where required. Mounting the
controller into a metal box which is shielded might be necessary.
5)
To insure the back shielded touch screen terminates to pin #3 (center pin) of H4.
It is required if a back
shield is available.
6)
Make sure the back shield of the sensor does not come in contact with any grounded part of the system.
IF PIN #3 IS CONNECTED IN ANY WAY TO AN EXTERNAL GROUND, YOU MAY PERMANENTLY
DAMAGE YOUR CONTROLLER BOARD.
7)
Such that the board, the LCD, and the computer system all have the same ground. Failure to have the
same ground throughout the system may result in reduced controller performance.
8)
The static ground mount must be terminated to a static ground before powering on the controller board.
Failure to follow this procedure will bypass the static protection and may damage the controller causing the
board to not function properly.
