PLANNING
It is very important to plan where the OmniTouch 5.7 Touchscreen will be installed and the gauge/type of wire you will use for the installation. The touchscreen can be connected directly to the HAI controller if video is not being used. However, if video is being used, the touchscreen must be connected to the HAI Touchscreen Hub. The HAI Touchscreen Hub can also be used if you are connecting multiple touchscreens (up to 8).
In selecting a place to mount the touchscreen, be sure to avoid an area where studs, plumbing, or electrical wiring may be located behind the wallboard. It should be mounted so that the display is at or slightly above eye level.
Wiring to the HAI Controller
When connecting the touchscreen directly to the HAI controller, run the power/communications cable (as determined by Table 1) from the controller location to touchscreen location. A minimum of 4 wires is required for operation (2 for power and 2 for communications). The required distance between the controller and the touchscreen will determine the wire gauge/type you should use. To prevent the touchscreen from drawing more than the specified maximum current from the controller’s power supply, do not exceed the "Maximum Cable Length" based on the wire gauge/type per the table below (Table 1).
