NOTE!! The board revision number can be found on a label on the back side of your controller board. The

firmware revision number may be found on a label or a laser mark located on the TSHARC microcontroller chip.

Integrating the TSHARC Capacitive Controller

Mounting the Controller

The controller has two .122” diameter (4-40 or 3mm screw) plated mounting holes. Notice the mountin g 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. For additional details about controller integration, please contact Microchip.

For best performance mount the controller:

1) In such a way to keep the touch screen tail away from high EMI, RFI and p ower sources.

2) “In line” with the touch screen tail limiting the number and severity of any bends or folds in the touch scre en

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 scree n 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 sens or 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 grou nd. Failure to have the

same ground throughout the system may result in reduced control ler perfo rmance.

8) The static ground mount must be terminated to a static ground before powering on the controll er board.

Failure to follow this procedure will bypass the static protection and may damage the controller causing the

board to not function properl y.

Figure 2: Controller Mounting Diagram

Although Microchip Technology Inc. has taken steps to protect your touch screen controller from transient

voltage, it is important to make all groundi ng, communicati on and touch screen connections to the

controller and touch screen. This must be done before po wering on your computer, video monitor or touch

screen controller. Failure to follow this procedure may result in damage to your controll er and/or

communication port. If you believe that your application will require additional static protection, it is up to

you to determine the appropriate static protection needed to protect your electro nics fro m transient voltage.

Failure to take the necessary precau tio ns may result in damage to your controller. Microchip does

not warranty the TSHARC controller board against transient static discharge damage.

Mounting the Capacitive Touch Screen

There are a number of methods that may be used to mount your touch screen depending upon your application and

the recommendations of your sensor supplier. In all cases it is important that you do not make any electrical

connections between the touch sensor and the integrated system. Please cont act your sen sor manufacturer for

specific mounting recommendations.

The sensor tail often experiences more electrical noise than the sensor itself. Special care should be taken when

considering the tail mounting o f the sensor. Please contact your sensor manufacturer for specific instructi ons

regarding the sensor tail.

In all cases, take special care to mount the touch screen in such a manner as to eliminate any screen shift or

movement during operation. The C-Ray controller gathers environmental variables at power-up. Any chan ges to the

touch screen position during use can negatively influence the performance of the system.

Connecting the Touch Screen

The TSHARC C-Ray, capacitive controller su pports back shielded, non-back shielded and shielded tail capacitive

touch screen overlays. Check the touch screen tail and verify the pin-out of the touch screen before you connect the

touch screen to the controller. If the touch screen has a back shiel d or a shielded tail a connection must be made to

the 3rd pin of header H4. Failure to connect a shielded touch screen or tail will cause the controller to malfuncti on.

This connection is shown in Fig. 3.0.

Note: Microchip’s touch screen mapping is consistent with all operating system display mapping specifications. Most operating

systems draw the screen from upper left to lower right.

Figure 5: RS-232 Cable Connection Diagram

The RS-232 communication c able can be connected to the controller using a variety of cable types. Part number

C72-100S2F-09XDXF cable may be sourced directly from Microchip Technology Inc. This is a standard 6’ long DB-9

female connector terminated to a (housing/contact) 10 p osition dual row socket via a round shielded cable. This

cable has a ground shield termination wire running the len gth of the cable which must be terminated to earth ground.

Not terminating the cable shiel d will have a negative effect on the controller’s performa nce.

Should a self-built cable be required, a 10-position, dual-row socket contact/housi ng connector type may be used to

connect the RS-232 communication header. If an IDC connector t ype is desired, a 14-position socket can be used,

which extends on to the USB pins with onl y the RS-232 communication connections terminated. A 10-position IDC

socket cannot be used for connecting to the communic atio n header because the width of an IDC socket is too wide to

fit between the USB connection pins and the pins needed for RS-232 communication.

Microchip also provides the option to use a single row, 2.0 mm, 7-pin connection to the serial commun ication

connection of the TSHARC-C controller board. This option may be used if it is desired to continue to connect the

TSHARC-C controller to your system which has already been configur ed for 3M™ Microtouch™ connections. Please

contact Microchip for ordering instructions regard ing this option.

Connecting the C-Ray for USB Communication

Take special care when connecti ng the USB cable. In correct pin selection using the USB cable will result in

a failed board when attemptin g to power the board. Also, be su re th e jump ers are configured the way

required for USB performance.

Connect the USB header contacts as shown in Fig. 7.0 for enabling USB communications with the controller board.

The USB contacts are located on the lo wer si de of the communication header. A 6’ long 4-position socket to a Type

“A” USB plug jacketed and shielded USB cable, part number C72-040S1F-04XAXM from Microchip Technology Inc

can be ordered. This particular cable has a ground shield terminatio n wire running the length of the cable which must

be terminated to earth ground. Not terminating the cable shi eld will have a negative effect on the controller’s

performance. For information about ordering this cable, please contact Microchip Technology Inc.

Special Note: If planning to use a USB-hub, then it is critical to use a hub which has externally supplie d power. If

multiple devices are attached to the hub, then be sure the hub has sufficient power to power all devices connected.

Failure to follow this recommendation will cause the controller to fail during operation.

Powering Your System

Before applying power to your system, please check all cables are tightly connected and verify the mounting of the

controller and sensor. If powering the controller using USB, the system power should be brought up at the same

time.

If using an external power supply, please be certain that the monitor is activated before the controller is turned on.

The environmental baseli ne is taken at power-up, and performance could be affected if the monitor is not present

when the controller is powered on.

Status LED Indicator

The TSHARC C-Ray capaciti v e touch screen controller board is equippe d with a status-indicator Light Emitting Diode

(LED). This LED will give you information regarding the functionalit y of the controller. The LED indication codes are

as follows: When powered on: The LED with blink once (on then off), collect an environment base line then

blink once again for 1 second. DO NOT T OUCH THE TOUCH SCREEN DURING THIS

PROCESS.

Every time the touch screen is touched: Once the controller has collected the baselin e, the LED

will turn off. It will turn on every time the operator touches the touch screen thereafter.

DO NOT TOUCH THE TOUCH SCREEN IMMEDIATELY AFTER THE CONTROLLER IS POWERED ON. THE

CONTROLLER MUST COMPLETE THE BASELINE PROCESS IN ORDER TO POWER ON CORRECTLY.

Static Protection Warning

The TSHARC C-Ray controller has internal static protection to +/- 30kV for static discharge from the touch screen to

the controller. This static protection is only effective once the board is grou nded properly. Adequate static

precautions must be taken when connecting the TSHARC controller to the application. In some ap plications, it may

be necessary to further protect your controll er board from excess transient voltage. If it is believed that the

application will requ ire additional static protection, the appropriate static protection needed to protect the electronics

from transient voltage is up to the customer. Failure to take the necess ary precautions may result in damage to

your controller. Microchip does not warrantee the board for static voltage damage.
