Using Axlink For Data And Power; Using Axlink For Data With A +12 Vdc Power Supply - AMX AXD-CP4/PB Instruction Manual

Installation
If you install the touch panel farther away from the Central Controller than recommended in the
Wiring Guidelines at 320 mA table, connect an external 12 VDC power supply to the panel, as
shown in FIG. 12 and FIG. 13.

Using AXlink for data and power

Connect the Central Controller's AXlink connector to the AXlink connector on the touch panel for
data and12 VDC power, as shown in FIG. 12.

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. 13 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.
Never connect both power wires from thepower 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.
4. Place the PWR wire from the power supply into the open clamp position for PWR on the touch
panel AXlink connector.
