INTRODUCTION
SHIPPING DAMAGE
On receipt of your Zytronic Projected Capacitive ZXY100® Touch Controller Touchscreen
Product, if you notice damage to the shipping carton, or concealed damage, be sure to save
all packing materials for later inspection by the carrier, who is responsible for any shipping
damage.
WARRANTY
If failure occurs during the warranty period of the product, please contact the point of sale
from which the product was purchased.
CARE AND CLEANING
Handle the touchscreen with care prior to and during installation. Do not pull or stress
cables/flexible cables and ensure no damage is caused to the touchscreen prior to
installation. Clean the touchscreen surfaces with a glass cleaning solution and soft lint-free
cloth. Ensure that the surfaces are clean and dry before integration of the touchscreen.
Industry standard Anti-static procedures for electronic equipment must be followed when
handling the touchscreen sensor and controller PCB during all stages of unpacking and
installation of the product to prevent damage to the product due to high levels of ESD.
UNPACKING YOUR TOUCHSCREEN
Ensure that the following items are present and in good condition:
Zytronic Projected Capacitive ZXY100® Touch Controller(s) and touchscreen sensor(s).
Users can download the latest Zytronic Projected Capacitive ZXY100® Touch Controller
Touchscreen Driver / Configuration Software and User Manual directly from the Zytronic
website. www.zytronic.co.uk/support
BEFORE YOU BEGIN
Before proceeding with the touchscreen installation ensure the following:
• Your Windows operating system is correctly installed and operating with your mouse.
• Ensure that all other touchscreen manufactures Driver Software/old touchscreen
Driver software is uninstalled from the host computer to avoid software conflicts.
• Ensure that there is a free USB or Serial port available on the host computer to connect
the desired Zytronic Projected Capacitive ZXY100® Touch Controller Touchscreen.
• Ensure that Industry standard Anti-static procedures for electronic equipment are

CONTROLLER VARIANTS
The Zytronic Projected Capacitive ZXY100®Touch Controller range consists of six distinct
variants. There are three different controller sizes suitable for different ranges of sensor sizes,
and each controller size is available in either USB or Serial versions.

For USB versions, a USB cable with mini-B plug is required. Serial versions require a Serial
cable with a Molex type connector, as specified in the Serial Cable drawing in section 10.0.

INTEGRATING
THE SENSWOR

INTEGRATING THE SENSOR
To integrate the sensor, you will require a suitably sized LCD with a display area close to the
active area of the sensor, as shown in Figure 5 (the active area of the sensor can be found on
the corresponding Zytronic sensor drawing). Where possible, it is advisable to have the
active area of the sensor 2-3 mm oversized on all four edges in relation to the LCD display
area. This will allow for some misalignment during integration.
FIGURE 5 SUITABLE LCD TO MOUNT THE SENSOR TO
Foam gasket should be used around the perimeter of the LCD to provide an air gap between
the LCD face and the rear of the sensor, as shown in Figure 6. This air gap is necessary to
prevent excessive electrical noise from the LCD causing interference to the sensor.
Guidelines for the required thickness of the gasket can be seen in the table below and are
sufficient for most LCDs. Some LCDs with very high levels of noise may require greater
spacing which would need to be determined by testing.

5 – 22˝ 3mm
22 – 32˝ 4mm
32 – 46˝ 6mm

FIGURE 6 FOAM GASKET APPLIED TO LCD TO PROVIDE AIR GAP BETWEEN LCD AND SENSOR
If the sensor is only to be fitted to the LCD temporarily and kept horizontal, a single sided,
electrically non-conductive, low performance gasket can be used, such as EPDM (Ethylene
Propylene Diene Monomer) foam sealing strip, as shown in Figure 7. For permanent
applications, or where the weight of the sensor is to be held only by the gasket, a higher
performance gasket such as 3M VHB tape can be used. This will normally require the gasket
to be built up to the correct thickness with several layers.
Different VHB tapes are available depending on the material of the surfaces it is adhering to.
Any gasket used must be non-sulphurous and maintain its adhesion at any temperature that
it may be subjected to in service.
FIGURE 7 GASKET APPLIED TO THE LCD PERIMETER
The sensor should be positioned on the LCD with the sensor active area (as defined on the
Zytronic product drawing) centred on the LCD display area. The glass face (with ‘Viewing
Face’ label) should be visible, as shown in Figure 8. The sensor can be positioned as shown or
rotated by 180 degrees (so that the flexible cables are on the top edge). The position should be
chosen which gives the best clearance for mounting the controller PCB on the rear of the LCD.
Sensor designs are also available with the flexible cables in alternative positions. If required, the
sensor can be cleaned on the front (glass) face and rear (polyester) face with a glass cleaning
solution and a soft lint-free cloth.

INTEGRATING THE CONTROLLER PCB
The components on the rear of the LCD should be arranged to allow a suitable space for the
controller PCB, as shown in Figure 9.
FIGURE 9 REAR OF LCD READY FOR CONTROLLER MOUNTING
The controller PCB should be positioned so that the flexible cable(s) can reach their
respective ZIF socket(s) without crossing over other cables or PCBs. There should also be
sufficient space around the USB socket to attach the cable. Ideally avoid placing the
controller within ~30mm of other PCBs and cables, as shown in Figure 10.

FIGURE 11 CONTROLLER PCB
The controller should ideally be mounted to metal standoffs pre-fitted to the metal chassis
so that there is a good low impedance ground connection between the controller PCB and
LCD metal chassis, as shown in Figure 12. The controller PCB should be spaced at least 5mm
away from the metal chassis.

FIGURE 12 TO METAL CHASSIS VIA METAL STANDOFFS
If mounting via metal standoffs is not possible, double sided gasket pads can be used. The
controller PCB should still be spaced at least 5mm away from the mounting surface, as
shown in Figure 13. Any gasket used must maintain its adhesion at any temperature that it
may be subjected to in service.

FIGURE 13 DOUBLE SIDED GASKET PADS MOUNTING OPTION
If gasket pads are used to mount the controller PCB, a separate ground connection from one
of the controller PCB screw holes must be made to the LCD chassis using a low impedance
ground cable, as shown in Figure 14.

FLEXIBLE CABLES
The flexible cable bend radius at the sensor edge, and along the cable length, should be a
minimum of 2.5mm, as shown in Figure 15.
FIGURE 15 FLEXIBLE CABLE BENDING AT SENSOR EDGE
The flexible cables should be plugged into the controller PCB, as shown in Figure 16.
FIGURE 16 FLEXIBLE CABLES PLUGGED INTO THE CONTROLLER PCB
The gold contact side of the flexible cable should be visible, as depicted on the label shown
in Figure 17.

Care should be taken to ensure the flexible cables are fully inserted into the ZIF sockets, as
shown in Figure 18.
FIGURE 18 CORRECT AND INCORRECT FLEXIBLE CABLE INSERTION INTO ZIF SOCKET
Once the flexible cables have been correctly inserted into the ZIF sockets, the ZIF connector
locking bars must be pressed down in order to lock the flexible cables into the ZIF sockets,
as shown in Figure 19.
