3Mount and ground the controller card. The grounding scheme for the controller should typically be determined consistent with EMI suppression requirements. This may be accomplished one of two ways:

•The controller should be mounted to the metal chassis using metal screws and spacers. It can be grounded through one of the mounting holes by using one of the No.6 sheet metal screws and spacers provided in the kit.

•If the controller cannot be mounted to a metal chassis, use a ground wire with a lug attached to connect one of the controller's plated-through mounting holes to chassis ground.

4Connect the power cable harness to the 2x5 male connector at P4 on the controller. Connect the other end to a power source. If a suitable +5 Vdc power source cannot be found inside the display, use a dedicated power supply. The 2500U controller power requirements are +5 Vdc nominal. Refer to Appendix C for current requirements.

5If you have grounded the controller to the metal chassis as preferred, the chassis ground connection through the power connector, P4 pin 8, does not need to be connected.

6Plug the X007X cable between the card and the bulk head mounting USB connector.

7Adhere the metal plate labeled with the legend, “Touchscreen Interface” to the outside of the bulkhead-mounted USB connector. A similar plate (see pg. 79 for part number) is also available with vertical labeling.

8Label the monitor to indicate that an IntelliTouch 2500U USB controller is installed inside the display.
