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. 8 shows the external power
supply diagram.
1.
Unscrew the PWR and GND wires on the terminal end of the power supply’s 2-pin cable.
2.
Pair the GND wires from the power supply and the Central Controller AXlink connectors
together; insert them into the clamp position for GND on the touch panel AXlink connector.
3.
Tighten the clamp and secure the two GND wires.
