Electroluminescent LCD Touch Panels
If you install the touch panel farther away from the control system than recommended in the Wiring
Guidelines for 1.5 A table, connect an external 12 VDC power supply to the 2-pin PWR connector
on the touch panel.
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 the AXlink for data with a 12 VDC power supply
Connect the Central Controller's AXlink connector to the AXlink connector on the touch panel and
external 12 VDC power supply as shown in FIG. 9.
Use an auxiliary 12 VDC power supply when the distance between the Central Controller and touch
panel exceeds the limits described in the Wiring Guidelines for 1.5 A table on page 9.
Connect only the GND wire on the AXlink connector when using a 12 VDC power supply. Do not
connect the PWR wire to the AXlink connector's PWR (+) terminal.
