Quick Start Guide : RC4Magic S3 DMX6dim

Most RC4Magic DMX6dim users will find all the information they need right here. Your DMX6dim (RC4Magic S3 DMX6dim or RC4M-900SX DMX6dim) also has a wide variety of advanced features. You can find out more about them in the RC4 Knowledge Base.

RC4Magic devices arrive ready to use. You probably do not need to change any settings. Just add DMX.

Refer to the RC4Magic DMX6dim quick start guide  for a diagram identifying the labeled features of the gear.

DMX6dim System Components :

To use your DMX6dim wireless dimmer you will need:

  • A DMX lighting console.
  • An RC4Magic Series 2 or Series 3 DMXio Transceiver.
  • A battery or DC power supply for the dimmer and loads you will be operating with it.

RC4Magic Private IDentities™ :

RC4 Private IDentities, unique to RC4Magic wireless DMX systems, keep your data private and safe on a Virtual Private Network (VPN) separate from other systems, with robust resistance to signal loss and slow down. Each Private ID transports a separate DMX universe. Multiple systems can operate at the same time for multiple wireless universes in the same space.

Each new RC4Magic customer and project is assigned a unique set of Private ID codes — nobody else has your IDs. They are marked on each device. Please note your private IDs below. When you add devices to your system, you must verify your IDs at time of purchase. ID3, code 999, is the RC4 Public ID. It is identical in all RC4Magic Series 2 and Series 3 devices ever made. Always use one of your private IDs when possible. Your Private ID0, the factory default, is ideal for most users.

Performing a Factory Reset :

If someone else has used your DMX6dim, or you just want to get back to a known configuration, performing a factory reset is easy: Power on the device. Wait until start-up is complete and the green COP indicator is blinking continuously. Press and hold the Function (Func) button, briefly tap (press and release) the SetABC button, then release Func. The first four indicators will blink to confirm that factory settings are restored.

NOTE: This process restores your RC4 Private IDentity™ to ID0. It does not change the Unit Number if one has been assigned. Learn more about IDs on the next page. Learn more about Unit Numbers when using RC4 Commander configuration software.

PRO TIPS: Bending a single paper clip into a U shape will enable you to easily reach and press both buttons together. If you are not sure what mode or setting you may have selected, you can always get back to a known starting point with a factory reset.

Confirming and Setting an RC4 System ID :

All RC4Magic devices being used together must be set to the same RC4 System ID. On power-up, the currently selected System ID is indicated with a blink pattern on the DMX Data and COP indicators. The four different patterns are noted below.  The factory default ID0 is indicated with a few rapid blinks of the yellow DMX Data LED on power-up. A factory reset will restore this ID setting.

An ID can be selected by holding one button or a pair of buttons on power-up. The blink pattern for the newly selected ID will appear on the indicators. You can also confirm the currently selected ID at any time by cycling power and watching the blink pattern that appears at start-up.

To select ID0, hold the SetABC button, apply power, and release the button when the blink pattern appears. To select ID1, hold the SetDEF button and apply power.
To select ID3 (the public, not private, ID), hold both SetABC and SetDEF and apply power.
NOTE: On 3-button devices, ID2 can only be selected with RC4 Commander software.

All RC4Magic Series 3 devices indicate IDs in the same way, making it easy to quickly confirm that all devices in your system are set correctly to work together.

ID0 (default), yellow blink. Hold SetABC on power-up to select ID0.
ID1, green blink. Hold SetDEF on power-up to select ID1.
ID2, yellow and green blink together. Cannot be selected manually.
ID3 (public), yellow and green alternate. Hold SetABC & SetDEF on power-up to select ID3. Note: ID3 is public and is less secure than Private IDs.

Connecting with an RC4Magic DMXio Transceiver :

All RC4Magic devices configured on the same RC4 Private IDentity™ will automatically connect and form a VPN (Virtual Private Network). Confirm that each device in your system is labeled with the same RC4 Private IDentity codes, and that each device indicates the same System ID selection on power up (see page 7). The default is ID0, which is fine for most users. When first powered up, or after a transmitter has gone off and then come back on line, receivers can take up to 10 seconds to join the VPN. This is normal, and it is usually much less than 10 seconds. A DMXio transceiver in Auto Mode (the default setting) will automatically detect wired DMX data from your console and establish itself as the master transmitter. RC4Magic devices from a different system will not work with your RC4 Private IDs. This is the key to RC4Magic data security and superior performance for all users.

RC4Magic Indicator LEDs After Power-Up :

The COP indicator blinks with different patterns to indicate various device modes. The DMX Data LED indicates that DMX data is present, either from a connected DMX controller, or from the VPN wireless link. If the yellow indicator is not active, no DMX data is present. DMX Data: Yellow blinks with data packets and may appear irregular (see pg 9 pattern)
DMX Data: Yellow blinks with data packets and may appear irregular.

On DMXio transceivers operating in transmitter mode (see page 8), the RF Connect LED blinks slowly to indicate that a wireless VPN has been formed and the DMXio is the master transmitter: DMXio, Transmit Mode COP Pattern: Green long blinks indicate transmitter mode (see pg 9 for pattern)
RF Connect: (see pg 9 for blue blink pattern)

RC4Magic Series 3 (2.4GHz) : If your DMX6dim has a purple and black label, it is part of an RC4Magic Series 3 system operating in the 2.4GHz band. The RF Connect indicator remains on (not blinking) while the DMX6dim is searching for your VPN. It blinks quickly and continuously while your DMX6dim is connected to your wireless VPN. DMX6dim RF Connect, Searching: (see pg 9 : long blue blink pattern)
Connected: (see pg 9 : blue blink pattern)

RC4Magic-900 (900MHz) : If your DMX6dim has a blue and black label, it is part of an RC4Magic-900 system operating in the 900MHz band. The RF Connect indicator is always blinking, and indicates only that the RF system is functional, not whether or not it has joined a VPN. Use the DMX Data indicator to confirm that streaming DMX is present.
DMX Data Received Wirelessly: (see pg 9 : yellow blink pattern)

Test the Wireless Link with Default Address Settings :

When you receive your new DMX6dim, or after restoring default settings, it will be set to DMX channel 1 for dimmer A, and channel 2 for dimmer B.

Before changing any settings, play with DMX levels for these channels to see your wireless dimmers work. DimA and DimB LED indicators are connected to dimmer outputs to show you exactly what the dimmers are doing.

Setting DMX Addresses and Curves with RC4 OneTouch™ :

RC4 OneTouch uses DMX channel levels to set parameters. To use it, the DMX6dim must be paired with an RC4Magic DMXio transmitter, and live DMX channel data must be streaming.

Begin with all channels in the DMX universe off, at zero (0). This includes channels used for house-lights, and moving-light parameters like pan and tilt.
Bring up one DMX channel. This will become the DMX6dim starting address, and the level of the channel selects a dimmer curve.

Tap a dimmer Set button to capture settings. They are now saved until you change them. Now you can return to using your DMX console normally.

Assign the DMX Starting Address :

Begin with all channels in the DMX universe off, at zero (0). This includes channels used for house-lights, and moving-light parameters like pan and tilt.

Bring up the DMX channel that will be the DMX6dim starting address. Set it to 30% (Decimal 77) to select a curve that is optimized for smooth LED dimming.

Tap the SetABC button to capture settings. They are now saved until you change them. Proceed to setting other dimmers, or return to using your DMX console as you normally do.

A channel level of 30% selects one of several different curves. Other curves are explained on page 13.

Subsequent Channel Assignment :

When you set DimABC, all 6 dimmers are automatically set sequentially. For example, if you have set DMX channel 74 for DimA, DimB is now assigned to channel 75, DimC is on 76, and so on, all the way up to DimF being set on channel 79.

Non-Sequential Channel Assignment :

Each set of 3 dimmers, ABC and DEF, are always sequential, but the two sets do not have to be. If you want DimDEF to be set to DMX addresses 11, 12, and 13, bring up 11 @ 30% (for the LED curve) at the board and press the SetDEF button. Remember: SetABC assigns all 6 dimmers sequentially. Always use SetABC first, then set DEF differently if you need to.

Connecting Your Lamps, LEDs, Motors and More* :

To really use your DMX6dim, you must connect a lamp, LED, motor, or other load to each dimmer. Be sure to remove power while making connections.

Screwdriver Size Matters :

The ideal screwdriver for the screw terminals on your DMX6dim has a blade that is 2.5mm (0.1”) wide. Forcing a screwdriver that is too big will enlarge the hole, so the terminal screws will fall out if you loosen them too much. A screwdriver that is too small will not ensure a firm grip on the wires and may lead to the screw head being stripped.

Dimming and Controlling Multicolor LEDs :

The illustration on page 12 shows an RGBATD (T is tungsten or warm white, D is daylight or cool white) color mixing LED device. There are 7 wires: a grey wire for the 12V common positive (+), and six colored wires, red/green/blue/amber/tungsten/daylight, for the six unique negative loads. The color of the common positive may vary, it is not always grey.

The common positive wire should be connected to either of the (+) terminals. All of the (+) terminals are connected together inside the DMX6dim. The two (+) terminals make it easy to connect two RGB light sources, each with their own common positive wire.

Dimming happens on the negative (–) terminals.
The red wire should be connected to the negative (–) terminal under DimA.
Green should be connected to the negative (–) terminal under DimB.
Blue connects to the negative (–) terminal under DimC.
Amber to DimD.
Tungsten (warm white) to DimE.
Daylight (cool white) to DimF.

If using two RGB fixtures or LED devices, connect the first one to DimA, B, and C, and connect the second to DimD, E, and F.

Choosing Other Dimmer Curves or Profiles :

The DMX6dim default is the ISL dimmer curve, which is best for LEDs. This is also the curve that is selected with RC4 OneTouch™ when the DMX level is at 30%. There are dimmer curves for different kinds of lamps, motors, and more. Detailed information can be found online by searching dimmer curves at RC4 Knowledge Base. The most common curves are selected using these DMX channel levels and RC4 OneTouch™ with the Set buttons as outlined on page 9:

Non-Dim 100% (80% or higher)
Use for relays, solenoids, air valves, etc.

Linear 70% (60 – 79%)
For incandescent, halogen, tungsten lamps.

ISL Fast 50% (40 – 59%)
For LEDs when fast blinks and flashes are required.
RC4 Digital Persistence™ is disabled.

ISL Slow 30% (20 – 39%)
Best for typical LED applications, with RC4 Digital Persistence™.
For super smooth 19-bit dimming. (default setting)

Advanced Features :

The DMX6dim is a multifaceted device for users of all experience levels. The features below can be explored further at RC4 Knowledge Base or by asking us for help at support@rc4wireless.com:

  • RC4 Commander software, available for Mac OSX and Windows, provides a rich user interface for configuring multiple RC4Magic devices remotely.
  • The DMX6dim can also be configured with an RDM controller, via a wired connection to the DMX/RDM data port. Wireless RDM is not supported.
  • Using a small adaptor cable, the DMX6dim can be used as a wireless data receiver to deliver DMX to other devices. It can also be used as a wired DMX dimmer: the miniplug DMX port becomes an input when the device is not linked to a transmitter.
  • When using the DMX6dim for cinema (motion picture capture), PWM frequencies can be adjusted for the smoothest dimming without banding or other artifacts.
  • The DMX6dim has a wide variety of dimmer curves that can ring telephones, position servo motors, and more (using DimC, D, E, and F).
  • Using the RC4 Flkr Effects Engine™, you can create many unique effects including candle flicker, analog tv screen noise, welding spark, and much more.
  • An HSL (Hue/Saturation/Level) processor can be enabled, making it easy to find a specific color and dim it up and down without color variation.

Caring for Your DMX6dim :

  • The DMX6dim should not be used with AC power or with any voltage higher than 35VDC. Doing so will severely damage the device and is extremely dangerous for the operator.
  • Do not exceed the maximum total power handling of the DMX6dim, which is 16A. That is 200W at 12V, 400W at 24V, shared across the six dimmer channels.
  • Always use a fuse or circuit breaker at the source of power and always use an appropriate wire size for the fuse rating. For example, if using a 15A fuse, use wire that can safely carry 15A.
  • The DMX6dim should be kept away from excessive heat, cold, dust and moisture.
  • Do not immerse in water or other fluids.
  • Dimmers generate heat when operating. Allow space for air to move around the unit for cooling, especially when using high-current loads.

The DMX6dim is a high-power, high-current device. Failing to observe appropriate safety precautions can result in fire or other risk. RC4 Wireless cannot be held responsible or liable in such cases. Operate the DMX6dim at your own risk.
