8.5" Black and White Touch Panels
Wiring the Touch Panel
The touch panels use a 4-pin AXlink connector for power and data. If the distance between the
panel and Central Controller exceeds power consumption limits, you must connect an optional
12 VDC power supply to the 2-pin PWR connector. The RS-232, AXlink, and PWR connectors are
located at the rear of the AXT-LC (TiltScreen), as shown in 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 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 touch panel can use either a
PS(N)2.8 (if the power is being supplied only to the touch panel) or a PS(N)6.5 power supply (if the
power is being routed through the touch panel to power another device). 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 table below lists wire sizes and the
maximum lengths allowable between the touch panel and Central Controller. The maximum wiring

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.
