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).
