Installation
9
8.5" Black and White Touch Panels
lengths for using AXlink power are based on a minimum of 13.5 VDC available at the Central
Controller's power supply. Refer to the
Specifications
section on page 1 for more information on
power requirements.
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 AXlink for data and power
Connect the Central Controller's AXlink connector to the AXlink connector on the touch panel for
data and 12 VDC power as shown in FIG. 8.
Using AXlink for data with a 12 VDC power supply
To use the AXlink 4-pin connector for data communication with the Central Controller and power
transfer from a power supply, the incoming PWR and GND cable from the power supply must be
connected to the AXlink cable connector going to the touch panel. FIG. 9 shows the external power
supply diagram.
1.
Unscrew the PWR and GND wires on the terminal end of the power supply 2-pin cable.
