1.
Check the
display
mounting for proper adjustment. Make sure all wires are properly
attached.
Check for video and power cables that originate inside the display. If these cables
exist, be sure to thread them through the appropriate opening in the display cover.
These will be reconnected through the stand.
Note:
When routing the sensor flex tail through the metal shield and rear display cover,
be careful to avoid the inverter and other high noise sources.
2.
Align the display cover for reattachment to the chassis and thread the sensor flex tail
through the hole.
3.
Remount the cover to the chassis assembly and attach the housing screws you
removed when you disassembled the display or use new longer screws as required.
Note:
Do not tighten the screws beyond the “just tight” position. Nylon threads strip
easily.
Turning On Your System
Before you turn on your custom system, ensure that all cables are connected properly and
that the controller is properly mounted. Be sure to tighten all cable connector screws.
To start up your system
1.
Turn on your display and computer.
2.
Adjust the contrast and brightness to suit your personal preference and working
environment.
3.
If necessary, adjust the horizontal and vertical position controls on the display to
center the image on the sensor.
Status Light (LED) Diagnostics
The DX123 controller provides two light emitting diodes (LEDs) D203 and D500 on the
component side of the board to indicate the status of the sensor unit.
Normal LED operation:
•
D500 indicates touch activity. If the controller senses touch activity the LED will
toggle from on to off or off to on. Each touch will cause the LED to toggle.
•
D203 indicates an active state when on. The LED will blink once during
enumeration and then remain on. When the controller is in standby/suspend mode,
the LED will be off.
Wake on Touch (USB Only)
If the controller is powered from a source inside the system that will not be shut down by
power management, the DX123 controller will wake up the system from standby mode
when touched.
