The maximum wiring lengths for using AxLink power are based on a minimum of 13.5
volts available. If the distance is greater than what is listed in the table, consult the
Metreau Keypads Operation/Reference Guide
for wiring with external power sources.
AxLink Data and Power Connections
Connect the control system's AxLink connector to the AxLink connector on the rear
panel of the Metreau Keypad for data and 12 VDC power as shown in FIG. 4.
Using AxLink for Data with an Auxiliary Power Supply
Use an auxiliary 12 VDC power supply when the distance between the controller and
server exceeds the limits described in the
GND (-) wire on the AxLink connector when using an auxiliary 12 VDC power supply.
Connect the NetLinx Controller’s AxLink connector to the AxLink connector on the rear
panel of the Metreau keypad, as shown in FIG. 5.
Note: If you are not using power from AxLink, disconnect the wiring from the controller
before wiring the Metreau keypad. Make sure the auxiliary power supply’s PWR (+) is not
connected to the controller’s AxLink connector.
AxLink Status LED
The AxLink Status LED (located next to the AxLink connector), lights to indicate AxLink
power/data status (see Operation / Reference Guide for details).
If the LED is on and not flashing, disconnect the AxLink connector and recheck all
AxLink connections. Then, reconnect the AxLink connector to the panel and verify the
LED is flashing once per second.
Mounting Procedures
AMX recommends mounting Metreau keypads in standard U.S.-style decora wallboxes:
• Conduit box should meet NEC specs (section 370)
• Minimum internal clearance of (HWD) 2-5/8" x 1-3/4" x 1-5/8".
Note: Before touching the device, discharge the static electricity from your body by
touching a grounded metal object.
Wallbox Mounting
1.
Use the cutout dimension for the wallbox to cutout the install surface.
2.
Connect the AxLink connector (or SWT cable connectors) to the rear of the
keypad.
3.
Place the Mounting Plate on the wallbox; align the screw holes with the mounting
holes and fasten the Mounting Plate to the wallbox using the screws supplied.
Note: Do not overtighten the screws when mounting the Mounting Frame. The device
should be flush with mounting surface.
