1.
Plug the sensor flex tail into the controller board, making sure that the pins are
oriented in the correct direction.
2.
Connect the USB or serial connector. You can also use an extension cable to run
from the controller board to the display chassis bulkhead USB or serial connector.
3.
Connect the 3-pin +5 VDC or 12 VDC power supply to the power connector.
4.
Check the controller operation by powering up the unit. LED D203 should be on to
indicate the device has power. LED D500 should toggle when touched (on one
touch, off the next.)
With the video and controller boards properly mounted, all cables connected, and excess
wiring cable-tied, the metal shield can be attached.
Sensor Flex Tail Connector
The standard 12-inch sensor flex tail has an 8-pin single row locking female connector
that plugs into the controller. The calibration process sorts out left/right and up/down if
the sensor is not used in the standard orientation.
If necessary, to make the sensor flex tail reach to the controller location, you can extend
the length of the tail with a one-to-one, non-shielded, flat ribbon flex tail extender. The
connector must be compatible with the connector manufacturer, i.e., Amp should connect
to Amp. Be sure to use tin compatible contact pins.

As mentioned earlier, it may be necessary to make changes to the metal shield and the
rear display housing to accommodate the sensor flex tail. Usually it is necessary to make
a hole in the shield and the housing so that the sensor flex tail can be routed through,
however some models may have an existing opening that can be used.
