CAUTION Observe polarity when connecting the power leads to the power supply. Reversing polarity may damage the controller.

Possible power supply sources included:

•A direct power cable to a +5 Vdc source inside the display or tap unregulated monitor power in the +9 Vdc to +30 Vdc range using the Elo DC-to-DC converter (See “Elo Part Numbers” on page 79). Attach the direct power cable (See “Elo Part Numbers” on page 79) to the source, red to + 5 Vdc and black to common. You must attach the green ground cable to a suitable chassis ground for noise immunity and safety considerations. Observe polarity when connecting the power leads to the power supply. Reversing polarity will damage the controller.

•Typical converter power consumption is approximately 1 W. Remember that each integration situation is unique; you must carefully evaluate available power rails and consider how drawing additional power from the display will affect monitor performance.

•Install a power supply which requires a 100-240 Vac input. Connect a power cable harness to P4 on the controller, a 2x5 header with pins on 0.100-inch (2.54 mm) centers. Use a ribbon cable with an IDC connector or crimp-to- wire pin receptacles. An acceptable plug can be selected from Molex series 70450, Amp AMPMODU Mod. IV product line, or Berg mini-latch housing with Mini-PV pins. Connect a power supply to the harness and then to AC.

•If none of the above options are practical, you must use either an optional keyboard power tap or wall-mount power supply to furnish +5 Vdc power to the controller.

CAUTION Before using a keyboard power tap, be sure sufficient power is available for the touchscreen controller or damage may occur to the computer.

Before connecting a keyboard power tap to the controller, be sure that power to the CPU is OFF. Connecting a keyboard power tap to a powered CPU may seriously damage the CPU or the controller and will blow the keyboard fuse.

1Decide where to mount the controller on the rear of the display case. After choosing a location, use masking tape to hold the template in the desired spot and drill a 1-inch diameter hole for cabling exiting the display and drill two holes for screws that will be mounted in the display case.

2Route the touchscreen cable (and power cable if using an internally located power source) through the 1-inch diameter hole in the display case. Insert the touchscreen cable into the keyed receptacle in the rear of the controller box. You will hear a “click” when the cable connector is properly connected to the controller. Pull any excess cabling back into the display case and attach the controller to the display case.

3Wrap excess cabling with tie wraps as required, and proceed to “Routing the Touchscreen Cables” on page 2-29.
