AMX RE-DM4 Low-Voltage Connections, Setting AXLink Address Numbers, Connecting AXLink, Example B

Low-Voltage Connections

The low-voltage area in the AMX Lighting controllers contain connections and DIP switches for AXLink, dry closures, and RDM module connectors. On the controller cards, low-voltage power for the board is supplied either by line power, optional auxiliary power supply (RDA-PSM), or the +12 VDC pin on the AXLink connector.

	Module connector/LED (CH5)

Each dry contact closure has two pins: ground and contact. To activate each dry closure, connect the ground and contact.

Setting AXLink Address Numbers

Set the AXLink address number (1-255) for the RE-DM4. This number must match the device number in your Axcess program.

Note: By turning all switches off, all circuits will go to 100 percent so that the installer can test the high-voltage connections without having connections to a control system.

Connecting AXLink

Connect the 4-pin captive-wire AXLink from the RE-DM4 to the Central Controller for AXLink control of the dimming system.

WARNING: Disconnect the main power to the AMX Lighting controller at the breaker box if rewiring the low voltage connections.

Dry Closure Connections

Dry contact closures from other equipment can be connected to the Radia Eclipse dimmer module to provide direct manual control of lighting loads (FIG. 5).
