Electroluminescent LCD Touch Panels
Wiring the Touch Panel
The RS-232, AXlink, and PWR (power supply) connectors are located at the rear of the AXT-EL+,
as shown FIG. 6. The connectors are located on the top-left corner of the rack-mount touch panels
as shown in FIG. 7.
Preparing captive wires
You will need a wire stripper, soldering iron, and flat-blade screwdriver to prepare and connect the
captive wires.
1.
Strip 0.25 inch of wire insulation off all wires.
2.
Insert each wire into the appropriate opening on the connector according to the wiring
diagrams and connector types described in this subsection.
3.
Turn the flat-blade screws clockwise to secure the wire in the connector. Do not over-torque
the screws; doing so can bend the seating pin and damage the connector.
Wiring guidelines
The touch panels require 12 VDC power to operate properly. The Central Controller supplies power
via the AXlink cable or external 12 VDC power supply. The maximum wiring distance between the
Central Controller and touch panel is determined by power consumption, supplied voltage, and the
wire gauge used for the cable. The following table lists wire sizes and the maximum lengths
allowable between the touch panel and Central Controller.
The maximum wiring lengths for using AXlink power are based on a minimum of 13.5 volts
available at the Central Controller's power supply. Refer to the
Specifications
section on page 1 for
more information on power requirements.

Do not connect power to the touch panel until the wiring is complete. If you are using
a 12 VDC power supply, apply power to the touch panel only after installation is
complete.
