Preparing captive wires
You will need a wire stripper, soldering iron, and flat-blade screwdriver to prepare and connect the
captive wires.
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.
1. Strip 0.25 inch of wire insulation off all wires and apply a light coat of solder to the ends using
a soldering iron.
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 table below lists wire sizes and the maximum lengths allowable
between the mini-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
Wiring Guidelines
Wire Size Maximum Wiring Length
18 AWG
20 AWG
22 AWG
24 AWG
If you install the touch panel farther away from the Central Controller than recommended in the
Wiring Guidelines table, connect an external 12 VDC power supply to the panel as shown in the
wiring diagrams in this subsection.
Using the AXlink mini-XLR connector for data and power (AXT-MLC and AXW-MLC)
Connect the Central Controller's AXlink connector to the mini-XLR connector (male) on the rear
panel of the TiltScreen and wood enclosure mini-touch panels for data and 12 VDC power, as
shown in FIG. 9.
