External Serial Controller

An external serial controller is the best choice for many integrators for several reasons:

•No additional cables are required to install the controller. The 30-inch touchscreen cable is routed through the rear of the display case to a 2x6 male connector located on the rear of the controller. Once the controller is installed on the rear of the display, little or none of the touchscreen cable is visible.

•The base of the controller may be permanently attached to the rear of the display, but is easily removed from the display if necessary.

•The serial cable is permanently connected to the controller and features an armored, moisture-resistant sleeve where the cable enters the controller enclosure.

•An external serial controller offers the added flexibility of using a keyboard tap or wall-mount power supply (See “Elo Part Numbers” on page 79) if using an internal power source is inconvenient or impractical. This feature places fewer constraints on the design and location of kiosks and other applications.

Follow these steps to install the IntelliTouch external serial controller:

1Determine supply power source to the controller. The controller requires +5 Vdc regulated power (± 0.25 Vdc) with 100 mA typical. Average power dissipation is 0.7 W.

CAUTION Before making any attempt to power the controller from any monitor power source, you should confirm the installation with your monitor supplier. Failure to observe this caution may destroy the monitor or seriously impair monitor performance.

•Provided you first confirm the installation with your monitor supplier, you may attach 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). 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.

If you have a suitable +5 Vdc power source, attach the direct power cable harness (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. Also ensure that the cable is long enough to reach the back of the monitor and the controller.
