5.5" Color Passive Mini-Touch Panels
Using AXlink for data and power (AXD-MCP and AXM-MCP)
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. 10.
Using AXlink for data with an external 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. 11 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 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.
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 table on page 9.

Never connect both power wires from the power supply and Central Controller to the
PWR terminal on the touch panel AXlink connector. Only the power supply’s PWR
wire should be connected to the touch panel AXlink connector. If both sources are
used to provide power to the touch panel, an electrical hazard is created and the
threat of both equipment damage and personal injury is likely.
