During the spacer selection process, you may have to install the CRT with the touchscreen attached in the bezel several times. To prevent the CRT from dislodging the spacers, temporarily insert plastic tie wraps or toothpicks as guides in the mounting post holes. After selecting the correct spacers, discard the guides and fix the spacers more securely in place with the adhesive "doughnuts" provided in the Touchscreen Installation Kit.
When spacers for the desired gap have been selected, install the CRT. Make sure you have previously reinstalled the degaussing coil. Select a screw that is long enough to compensate for the spacer thickness (provides at least three full turns into the mounting post threads) but not so long as to penetrate the surface of the bezel.
Installing the Controller
Elo offers IntelliTouch USB or serial
Before installing an IntelliTouch controller, you need to ensure the following design conditions:
•Ensure there is space for the controller and the cable headers.
•Note that cable routing may contribute to noise and crosstalk. Make sure the controller is placed away from voltage sources.
•Ensure there is space for an internal
•Verify power source and check specs for adequate power. The 2500 controllers use +5V@60 mA ±5% regulated.
•Ensure sufficient electromagnetic Interference (EMI) suppression. Installing a touchscreen and controller will affect the EMI characteristics of the display.
Note: Ensure sufficient heat dissipation. The IntelliTouch serial controller dissipates some heat (less than 1 watt). A typical power supply, if required, may dissipate several watts more. This places an additional load on the cooling system of the display. The available locations to mount a controller and power supply may also affect the cooling system of the display. Only applicable if you are not using
•Ensure controller can be mounted securely to metal bracket and grounded.
•Ground at least one mounting hole, but for best EMI characteristics, ground all four mounting holes.
