Frequently Asked Questions - RDM-2INC AMX

How do I install the RDM-2INC dimmer?

First, disconnect power at the circuit breaker. Mount the dimmer on a DIN rail or in a standard wall box. Connect line (hot), neutral, and load wires per the wiring diagram in the manual. Ensure the total load does not exceed 1200W. Restore power and verify operation.

What type of lamps can I use with this dimmer?

The RDM-2INC is designed for incandescent lamps only. Do not use with LED, fluorescent, or low-voltage lighting unless a compatible converter is used. Check the load rating: max 600W per channel, 1200W total.

How do I set the dimming curve?

The dimming curve can be configured via RDM commands. Use a compatible RDM controller to select from preset curves (e.g., linear, square law). Refer to the manual for RDM parameter IDs and settings.

What is RDM and how does it work with this dimmer?

RDM (Remote Device Management) is a protocol that allows bidirectional communication over DMX512 cabling. With the RDM-2INC, you can remotely set parameters, monitor status, and identify the device without physical access.

Why is my light flickering or not dimming smoothly?

Flickering can be caused by incorrect wiring, exceeding the load limit, or using incompatible lamps. Ensure the load is within specifications and all connections are secure. Try resetting the dimmer by cycling power.

How do I reset the dimmer to factory defaults?

To reset, disconnect power for 30 seconds. Alternatively, send a factory reset command via RDM using a controller. Note that reset will clear all custom settings and restore default dimming curve and addresses.

Can I use this dimmer in a three-way switch setup?

No, the RDM-2INC is a single-pole dimmer and is not designed for three-way or multi-location switching. It must be controlled via DMX/RDM signals. For multi-location control, use additional RDM-enabled devices.

What is the warranty period and how do I claim it?

The dimmer comes with a 2-year limited warranty. To claim, contact AMX support with the model and serial number. Proof of purchase is required. Do not attempt to open the unit; warranty is void if tampered.

How do I clean and maintain the dimmer?

Clean the exterior with a dry, soft cloth. Do not use water, solvents, or abrasive cleaners. Ensure vents are free of dust. No internal maintenance is required. If issues arise, contact a qualified technician.

Can I control the dimmer without a DMX controller?

The RDM-2INC requires a DMX512 or RDM controller for operation. It does not have onboard controls or a standalone mode. For simple on/off, use a separate relay. The dimmer is intended for professional lighting systems.

Installation

Space Requirements

AMX Lighting control installations require very little space. Enclosures are the main concern. All enclosures are mounted flush, on a vertical surface and must have a minimum clearance of 12" (304.8 mm) above and below to allow for air circulation. Physical dimensions for each enclosure are described in the Installation section.

Conduit

Conduit runs depend on the enclosures you use and their AMX Lighting modules. All enclosures have conduit knockouts on the top for high-voltage connections, and knockouts on the bottom for low-voltage connections. All conduit knockouts allow for 1/2, 3/4, and 1-inch (12.7 mm, 19.0 mm, and 25.4 mm) conduits as shown in FIG. 3. You should also consider these recommendations prior to installing enclosures:

• Install separate conduit for lighting loads. The recommended knockout for loads is located on the top center of the enclosure.
• Install separate conduit for the 120 VAC wiring to the line input terminal block. The recommended knockouts for incoming power feeds are located on the top-left and top-right sides of the AMX Lighting enclosure.

Install separate conduit for low-voltage signals for dry closures, AxLink, and PROlink connections. The recommended knockout for these control connections is located on the bottom of the enclosure. There are additional knockouts on the bottom-left and bottom-right sides of the enclosures for alternate low-voltage connections.

FIG. 3 Knockout locations (RDA-ENC2 used as example)

Install the control modules according to local and National Electrical Code (NEC) regulations.

Installing RDM Modules Into an Enclosure

Installing any of the RDM modules is an easy task. The individual modules are shipped with the four mounting screws enclosed.

To prevent possible personal injury or death, cut off power to the enclosure at the breaker box before attempting to install any AMX Lighting modules.

FIG. 15 illustrates the inside of an RDA-ENC6 enclosure and the mounting slots. The modules are positioned in the appropriate slot and secured using the supplied screws.

FIG. 15 Enclosure module mounting slots and mounting screw holes

The RDA-ENC2 enclosure contains a ground-terminating lug. The RDA-ENC4, RDA-ENC6, RDA-ENC6B, and RDA-ENC12B enclosures contain a neutral terminating block and a ground-terminating lug.

Low-Voltage Connections

All low-voltage connections must comply with Class 2 wiring codes.

The low-voltage area in the AMX Lighting controllers contain connections and DIP switches for AxLink, PROlink, dry closures, and module jack 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.

There is also a green status LED on the controller circuit board that blinks, according to the current operating status of AxLink and red LEDs, one for each of the external connectors for additional modules.

Figure 18 shows an example of the low-voltage connections, DIP switches and LEDs using the RDD-DM4 controller.

FIG. 16 Low-voltage connections and DIP switches

Module Connections

When connecting a dimming/switching module to a AMX Lighting controller, connect as shown in FIG. 17.

FIG. 17 Module connection to a con-troller card

Green Status LED Indicator

When you apply power to the AMX Lighting Control System, the green status LED notes its conditions:

- It is on full when power is applied to the control module.

- It blinks on and off when AxLink communication is present.

- It is off after default initialization is complete.

The LED indicator is located near the dry closure connector on the control module.

Red Status LED Indicators

The red LED's function is to indicate level. LED brightness increases as signal level increases from zero to 100. The LED indicator is located above each external load connector jack on the control module.

Configuring and Connecting PROlink

On all AMX Lighting controllers, DIP switch SW2 sets the PROlink pack number. The pack number is determined by the value of all the switch position settings. The following table shows the SW2 DIP switch positions and their values. The pack number assignment range is 1 through 10. The lighting system will not work if you assign a pack number outside of the range.

6 Channel 6 at 100%	in 1 second*
7 Pack on (channels	1-6)*
8 Pack off (channels	1-6)*
*All other channels are undefined.

Default Mode (Reset)

Default mode is resetting the AMX Lighting module values to zero and the module then begins to function on the values you previously programmed into the module. If you experience problems after installing a lighting system, you may need to reset the controller module to default mode. Then, you should be able to determine if there is a problem with the connections, programming, and/or dimming.

To reset a AMX Lighting controller to default mode:

1. Power off the AMX Lighting enclosure at the circuit breaker panel.
2. Disconnect all AxLink and PROlink cables from the controller module.
3. Connect a jumper to the dry contact closures 1 through 8 and to ground as shown in FIG. 22.

FIG. 22 9-pin dry closure connector set to default mode

1. Power up the controller enclosure and wait for the controller's green status LED to go off after approximately 1 minute.
2. Using a non-conductive rod or wooden one-quarter inch dowel rod (approximately 12" long) press the RESET button located on the controller module circuit board.
3. At the breaker panel, remove power from the controller enclosure.
4. Remove the jumpers from the dry contact closure connector.
5. Reconnect the AxLink and PROlink connections.
6. Power up the controller enclosure.

External Power

The following table lists the modules that use most of the operating power a AMX Lighting control module can supply. They may require extra power from the AxLink connection, or an external power supply connected to the control module or module(s) when using multiple modules.

Compatible Ballast Information

This section contains descriptions and manufacturer information on AC-controlled magnetic ballasts, AC-controlled electronic ballasts, DC-controlled electronic ballasts, and ballast interfaces that are compatible with the AMX Lighting Control System.

WARNING

The ballasts listed in this section have been reported to AMX by other parties to be compatible with AMX Lighting dimming systems. AMX has not tested every ballast/dimmer combination, and cannot verify either compatibility or correct operation. AMX does not specifically recommend any particular ballast make or model. Contact AMX for information regarding ballasts not listed.

AC-Controlled Magnetic Ballasts

AC-controlled magnetic ballasts are simple circuits that smooth out the raw AC power to lamps. They should not be used in presentation dimming applications because they do not perform well in lower dimming ranges.

NOTE

AC-controlled magnetic ballasts are not recommended for critical lighting control.

AC-Controlled Electronic Ballasts (3-Wire Ballasts)

AC-controlled electronic ballasts deliver smooth flicker-free operation down to 1% brightness at low light levels for some models (under ideal conditions). The ballast receives an AC dimming signal and interprets the appropriate response to the lamps. AMX Lighting can control AC-style ballasts using the RDM-FDB satellite module.

The following table lists compatible AC-controlled electronic ballasts.

DC-Controlled Electronic Ballasts (4-Wire Ballasts)

The DC-controlled Electronic Ballasts track a 0-10 or 0-12 VDC channel for dimming and an AC switch channel for on/off. This ballast design is better than magnetic, but many stop dimming at about 20% brightness. That's fine for energy management and secondary lighting zones, but not for primary lighting that requires precision, low-level dimming control.

Ballast Interfaces and 2-Wire Ballasts

In some cases, dimmers are wired to ballast interfaces (provided optionally by lighting suppliers), rather than directly to the ballasts. A few interfaces are driven from a standard AMX Lighting incandescent channel, while most use FDB dimming configurations.

Glossary

Air Gap Switch - A relay or mechanical switch that physically separates a load from the power feed, resulting in an air gap between the contacts. An air gap is a deliberate and noticeable space or disruption in a circuit causing an open condition.

AxLink - A four-wire data bus used to transmit and receive data from the AxLink Central Controller to any of 255 devices on the system. An AxLink address designates which of 255 possible devices assigned to the main AxLink is assigned to the Radia Lighting controller.

Ballast - An electrical device used in fluorescent and HID fixtures. It furnishes the necessary starting and operating characteristics to the fluorescent lamp for proper performance. Not all ballasts can dim lights. Fluorescent ballasts may contain the following:

• Ballast reactor
• Auto-transformer
  ● Power factor correction circuit

Breaker - An automatic switch that stops the flow of electric current in a suddenly overloaded or otherwise abnormally stressed electric circuit. A circuit breaker is an air gap switch.

BTU - The acronym for British Thermal Unit. This term also applies to the amount of heat required to increase the temperature of a pound of water one degree Fahrenheit. It is used to measure the thermal or heat-producing effect of a device.

CFL Lamp - An acronym for Compact Fluorescent Lamp (a type of fluorescent lamp).

Channel (Radia Lighting) - The Radia Lighting processor's dimming engine recognizes six independent levels and paths of output control. These control paths are called dimming channels or just channels. Each Radia Lighting master controller (pack) has six channels of control. AxLink channels are used in Axcess programming and apply to operation using an AxLink system.

Choke - A device used in electric circuits to oppose changes in the magnitude or direction of current flow. A choke device reduces noise caused by lamp filaments and is also known as a "dc-buzzing coil."

Contact Closure - A circuit is formed when the two contacts of an open circuit are brought together. The Radia Lighting master controller uses TTL logic levels normally pulled High to 5v. A closure to ground pulls the level to logic Low and is read as a closure. Each of the eight closure inputs is independently operated and controlled.

Contactor - A type of relay that accepts large current loads greater than 20 Amps, usually with a 120-volt primary coil. A contactor is helpful in allowing a 120-volt control signal to switch a large circuit at 277 volts.

Dimmer - A device located in an enclosure that is capable of dimming a light or electric circuit. Each dimmer is rated by Wattage and Voltage.

Electronic Transformer - A transformer that reduces the voltage output when the primary voltage of the transformer is reduced. This causes the secondary output of the transformer to reduce its voltage through electronic means. Electronic transformers should be specifically designed for standard dimming. Some electronic transformers are not dimmable or exhibit poor dimming performance.

Enclosure - The UL-approved box into which Radia Lighting control cards, modules, and accessories are installed.

Fade - A steady change in lighting levels expressed in seconds of time. A fade can encompass an individual or group of dimmers. A preset can be set to fade into another preset where one or more lights dim, increase in brightness, or stay at the same level.

Fade Rate - The amount of time it takes to change from one preset to another, or from one level to another, and is expressed in seconds.

FDB Ballast - FDB ballast are made by Lutron Electronics. The ballast are controlled using a switched hot and a dimmed hot in combination. An RDM-FDB module is one that dims FDB ballast with an AC current using a solid state dimmer and a switched feed through a relay. Lutron ECO-10 ballast are also controlled in the same manner.

Fluorescent Lights or Lamps - A lamp that produces visible light by fluorescence (producing light when acted upon by radiant energy). The lamp consists of a glass tube, the inner wall of which is coated with a material that fluoresces when bombarded with secondary radiation generated by a gaseous discharge within the tube. Control systems affect the ballast, not the lamp.

Halogen Lights or Lamps - A halogen lamp is a type of incandescent light source that uses halogen gas in an enclosed capsule. It uses the halogen regenerative cycle to prevent blackening of the lamp envelope during life. Halogen lamps are dimmed using a standard incandescent dimmer.

Integrated Dimmer Module - A Radia Lighting device that contains both a six-channel master controller and dimmers on the same package. They will have a PROlink address and can be on AxLink. The RDD-DM4/ series and the RDD-DM6/ series are integrated dimmer modules, and they all take up two module spaces.

Level Time - A Radia Lighting default parameter. Level time is the time it takes for a dimmer to reach its assigned level after receiving a level command.

Line - The wire or circuit that supplies power to a dimmer or electrical device. The line wire often comes from an electrical circuit breaker panel.

Load - The particular device or resistance of a device to the power being delivered. Also the total amount of devices connected to the output of a dimmer or switch. The load wire connects from the dimmer to the lamps. Lights are common loads along with motors and other power equipment.

Pack - A Radia Lighting Central Controller consisting of six channels of control on the PROlink control bus. Pack settings of 1 through 10 allow for 10 six-channel packs for a total of 60 channels of control on one PROlink bus.

Peak Switch - A switch that opens or closes at the height of the AC cycle, as opposed to the zero-cross point of the AC cycle.

Phase Dependent - A dimmer module must have its supply voltage on the same phase (A, B, or C) as the electricity supplied to the controller. Only dimmer modules are phase-dependent.

Port (Control Port) - A four-pin connector used to connect a Radia Lighting module to a controller. There is a maximum of six ports on the Central Controller.

Power Consumption Rating - An amount of energy used by a device to perform its function at maximum load. Radia Lighting devices have power consumption ratings expressed in milliamps (mA). Radia Lighting controllers provide this power to operate the modules and can also get more power from external power supplies.

Power Rating - Ratings expressing the maximum load capacity of a module, dimmer, or switch. Radia Lighting power ratings are based on UL testing and approvals.

Preset - A preset is a stored scene. Presets can consist of a single dimmer or any combination of dimmers as a group of stored values. Radia Lighting presets allow a dimmer or any combination of dimmers to be excluded from a preset.

Preset Fade Time - A Radia Lighting default parameter. The amount of time it takes for one preset to begin to fade out and another preset to completely fade in.

Preset Ramping - The active preset can be ramped to a different level while retaining the proportions and integrity of the preset scene. A preset can be dimmed so that all levels are zero and recovered or brought to full brightness and the dimmed back down to the original settings.

PROlink - A four-wire data bus used to transmit and receive data from pack to pack. A PROlink address designates which six channels of control will be assigned to a pack, up to 10 pack addresses and 60 channels of control.

Ramp - The increasing or decreasing of a light level on a continuous grade or increment.

Ramp Rate - The time it takes for a dimmer or group of dimmers to go from their present level to full light level or zero light level via a ramp command, expressed in seconds of time.

If a dimmer is at 50%, then a 5-second ramp rate means it takes 5 seconds to go from 50% to 0, or from 50% to 100%. If a dimmer is at 75%, then a 5-second ramp rate means it takes 5 seconds to go from 75% to 0, or from 75% to 100%.

Relay - A controlled device that interrupts or connects a circuit.

Satellite Module - Any Radia Lighting dimmer or switch module (RDM-series).

Scene - The condition or status of all dimmers in a designated area or zone. A stored scene is a preset. A preset recalled and then changed becomes a scene.

Common building and residential electrical panels provide three phase power where the potential difference between any phase and neutral is 120 VAC. The Radia Lighting PRO enclosure accepts three phase power.

Transformers - A device for altering the voltage of an AC supply. Transformers are commonly used to step down a higher voltage to a lower voltage used by the lamp. Transformers can also be used to step up a voltage such as a neon transformer that outputs thousands of volts from a 120 VAC feed.

Undefined (level) - A level setting that causes a channel to be excluded from a preset.

Zero Cross - The point where the AC waveform is at zero potential to ground is called the zero cross point. The zero-cross point is used as a common electrical reference in a dimming circuit and provides a synchronized reference point for opening or closing a relay. The zero-cross point is determined by the phase of the line input power and neutral.

Zone - A zone is an area of lighting under independent control. It can be made up of one or more dimmers. A lighting zone can be one table lamp or an entire corridor. Common usage has one dimmer to one zone, but a lighting zone can be made up of many dimmers.
