This guide will get you started using your RC4 LumenDimPix. Most LumenDimPix users will find all the information they need right here. Your LumenDimPix also has a wide variety of expanded features for advanced users. You can find out more about all of them in the RC4 Knowledge Base at http://rc4.info.

Refer to the quick start guide manual for numerous diagrams identifying the labeled features of the gear.

LumenDimPix Quick Start Guide : Your RC4 LumenDimPix has a wide variety of patented features that reduce the number of DMX control channels needed to create beautiful looks with up to 1000 pixels. Parameter settings, as a group, are called an RC4 Custom Pixel Profile, or CPP. CPPs are ideal for pattern-based (rather than videobased) applications of pixel tape, pixel panels, festoon strings, and other pixel products. The small size and light weight of the LumenDimPix make it perfect for costumes and small props, even hats and wigs.

Right out of the box, the LumenDimPix operates like most DMX-controlled pixel drivers. The default CPP settings let you immediately start controlling up to 170 APA102* three-color pixels with one 512-channel DMX universe, starting on the first channel.

This guide helps you discover how to make big looks with fewer resources and in less time, using any of the most popular pixel types, including 3-wire and 4-wire data formats, 3-color and 4-color pixels, and more.

LumenDimPix System Components : To use your LumenDimPix wireless dimmer you will need:

• A DMX lighting console.
• A LumenRadio CRMX-compatible wireless transmitter like the RC4 LumenDimIO or the LumenRadio TX1.
• A battery or DC power supply for the LumenDimPix and pixel products you will be operating with it.
• A set of Phoenix connectors (one set is included with the LumenDimPix)
• A small tool, like a bent paperclip, to press the recessed buttons on the LumenDimPix, and to press the wire-release buttons on the connectors or power and pixels.
• A pixel product, like APA102 (the default) or WS2812 pixel tape.

* APA102 is one of several types of pixel. It uses a high internal PWM frequency, making it ideal for motion picture capture without banding or other visual artifacts.

Phoenix Connectors for Power and Pixels : Power and pixel connections are made with Phoenix COMBICON FK-MC Series removeable connectors. One set of mating connectors is included with the LumenDimPix. Additional connectors can be purchased from RC4 Wireless. *

Connecting wires is easy:

• Wire must be in the size range of 0.5mm2 to 0.75mm2 (20 – 18 AWG).
• Strip 8mm (5/16 inch) of insulation from the end of each wire.
• Use a small screwdriver to hold down the orange spring-release button above the wire-entry hole.
• While holding the button, fully insert the bare wire end into the hole.
• With the wire fully inserted, release the orange button.
• Firmly but gently pull back on the wire to confirm a good grip on the wire.

NOTE: It is helpful to use a small vice, spring-loaded clamp, or pliers to hold the connector upright while inserting wires.

Performing a Factory Reset : If someone else has used your LumenDimPix, or you just want to get back to a known configuration, performing a factory reset is easy: Power on the device. The green COP indicator will be blinking. Press and hold Func, briefly tap (press and release) the SetA button, then release Func. The DMX Data and COP indicators will blink several times to confirm that factory settings are restored. NOTE: This does NOT affect transmitter linking. 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, pixel type, or other settings you may have selected, you can always get back to a known starting point by returning to factory defaults.

Unlink the LumenDimPix : For all RC4 Wireless products, LED indicators are behind small round holes. Buttons are behind small slots. Do not push tools into round holes. Use a bent paperclip or small screwdriver to push buttons. If the blue RF Connect LED on the LumenDimPix blinks continuously, it is looking for a transmitter that it was previously linked with. To unlink it, use a bent paperclip or small screwdriver to press and hold RF Connect for several seconds until the blue LED goes off and stays off. If the RF Connect LED remains on, or is blinking, repeat the process until it stays off. When the RF Connect LED is off, the LumenDimPix is ready to be linked to your
transmitter.

NOTE: Link status is not affected by performing a Factory Reset (see page 7 of the quick start guide).

Linking Transmitter and Receiver : In this example, we’re using an RC4 LumenDimIO transmitter. If you’re using a different transmitter, be sure it is CRMX-compatible, to work with LumenRadio devices. Refer to your transmitter user manual for specific linking instructions. Have both devices powered on. Put the LumenDimIO Mode switch in the transmit position, then tap the Link button. The Link button is recessed under the small slot to the right of the blue RF Connect LED. Tap it with a small screwdriver or the end of a bent paperclip. The blue RF Connect LEDs on both the LumenDimIO and the LumenDimPix will flash for several seconds and then remain steady, indicating that they are linked.

RC4 Custom Pixel Profiles™ : The LumenDimPix with patented RC4 Custom Pixel Profiles™ (CPP) provides a simple but powerful means of creating and controlling up to 1000 pixels. RC4 CPP vastly reduces the number of channels needed, while supporting a level of designer creativity not possible with other channel-saving techniques. Unlike drivers that provide preset or canned effects, CPP still allows you to create your own patterns in real time from your DMX console.

Instead of having your console handle the replication of patterns across a large number of pixels, which consumes at least 3 channels (and sometimes more) per pixel, that duty is moved to the pixel driver and handled by RC4 Custom Pixel Profiles™.

Keyframes
You decide how many DMX channels will be used for creating your pattern by setting the Keyframe Length. A Keyframe Length of 170 pixels (the default) will map 510 DMX channels directly to pixels, as is done with most DMX-controlled drivers.

Setting a shorter Keyframe Length reduces the number of channels needed to display patterns nearly identical to what an expensive console generates using multiple universes and huge numbers of DMX channels.

The keyframe length can be anything from 1 to 170 pixels long. A particularly powerful and channel-conservative Keyframe Length is 60 pixels*, which utilizes just 180 DMX channels, approximately 35% of one DMX universe.

Replication (Duplication, Mirroring, etc.)
The LumenDimPix and CPP driver replicates the keyframe down the entire length of connected pixels, up to 500 for each of two pixel driver ports. A variety of Replication Methods are available to choose from, and more will be added with future firmware updates.

Replication works even with a Keyframe Length of 170, allowing one port to control 500 pixels with only the data for the first 170. Two ports provide a total of 1000 3-color pixels controlled from a single LumenDimPix.

Grouping
Another way to reduce DMX channels while controlling more pixels is Grouping. In this case, the LumenDimPix with CPP controls multiple physical pixels with one console pixel. A Group Length setting of 3 will cause each console pixel to control three physical pixels in a row. This is the equivalent of nine (or more) DMX channels if done from the console. Grouping effectively widens the visual pattern or effect without consuming more DMX channels.

The combination of Keyframe Length, Group Length, and Replication Method, applied to patterns generated live by the lighting console, ensures maximum creative flexibility while substantially reducing the number of DMX channels needed. CPP parameters are described in detail on pages 14 – 17 of the quick start guide.

* A Keyframe Length of 60 is evenly divisible by 2, 3, 4, 5, 6, 10, 12, 15, 20, and 30, making it easy to create the appearance of varying pattern lengths without the need to actually change CPP settings in the LumenDimPix. Of course, there are numerous lengths with interesting benefits and advantages.

RC4 OneTouch™ for Setting Parameters with DMX Channel Levels :

NOTE: To use RC4 OneTouch™, the LumenDimPix must be paired to a CRMX transmitter, and live DMX channel data must be streaming.

RC4 OneTouch™ uses four DMX channel levels to assign values to LumenDimPix parameters. Channel levels are captured and saved with the press of a single button for each driver port using the SetA and SetB buttons.

While you are using RC4 OneTouch™, only DMX channels that are setting parameters should be at levels above zero. All other channels should be off. NOTE: Channels being used in your DMX system for house-lights and moving light parameters (like pan and tilt) must also be at true zero.

When a RC4 OneTouch™ button is pressed, the driver sets the first non-zero channel as the DMX Start Channel. In addition, the level of that channel selects one of four popular pixel types. The three channels immediately following the DMX Start Channel are used to set Keyframe Length, Group Length, and Replication Method.

Settings are remembered even when power is cycled. After parameters are set, return to using your DMX console as you normally do, controlling LumenDimPix pixels and everything else in your lighting system.

Using RC4 OneTouch™ is easy:
1. Set channel levels to reflect desired settings for a driver port.
2. Press the Set button for the port.
3. Repeat for other ports, and other devices in your system.
4. Proceed with using your DMX console as you normally do.

RC4 OneTouch™ Implementation in LumenDimPix : In the implementation chart shown below, channel S is the DMX Start Channel, range 1 to 512. The level of channel S and the next three channels set RC4 Custom Pixel Profile™ parameters. Parameters are described in detail on pages 14 – 17 of the quick start guide.

Before pressing a Set button, the start (S) channel must be at the correct level for the pixel type being used. If the level of any subsequent parameter channel is at zero, the previous setting for that parameter is retained. This makes it easy to change only the start channel and pixel type.

DMX Start Channel for Pixel Control:                       S (any chan from 1 to 512)
Keyframe Length in Pixels:                                        S + 1
Group Length in Pixels:                                              S + 2
Pattern Replication Method:                                     S + 3

RC4 OneTouch™ channel levels only matter at the moment a Set button is pressed.
Example:
DMX Start Channel 74 (first non-zero ch is 74)
WS2812 Pixel Type (start ch at level 77, which is 30%)
60-pixel Keyframe Length (first ch above Start, ch 75, set to level of 60)
Pixels controlled in Groups of 3 (ch76 set to level of 3)
Increment/Decrement Replication Method (ch 77 at 55, which is 22%)

(Refer to page 13 of quick start guide for further reference)

Set DMX Start Channel and Pixel Type for Each Port : To use RC4 OneTouch™, the LumenDimPix must be paired to a CRMX transmitter, and live DMX channel data must be streaming. The first channel in the DMX universe that is at a non-zero level will be assigned as the DMX Start Channel. The Start Channel must be at the correct level for the pixel type being used : Refer to page 14 of quick start guide for guide.

* WS2812 is the most common data protocol for pixel control. There are many compatible products. If you are using a 3-wire device with D but no C connection, it will most likely work using the WS2812 driver setting. The SK6812RGBW uses the same data protocol but allocates 4 control channels to each pixel, for 4 colors.

Select Pixel Color Order : Repeatedly pressing the same Set button will cycle through 6 color orders. Select the color-order of the pixel product being used, and the LumenDimPix will re-order the control channels for red/green/blue control from your console. Refer to diagram on page 15 of quick start guide.

Set Keyframe Length in Pixels : The channel immediately after the DMX Start Channel sets the Keyframe Length in pixels, limited to the range 1 – 170. A value of zero will be ignored, so the previously set Keyframe Length will remain unchanged. Values higher than 170 will set a length of 170 pixels. The default Keyframe Length is 170 RGB pixels, using 510 DMX channels. Refer to diagram on page 15 of quick start guide.

Set Group Size in Pixels : The second channel after the DMX Start Channel sets the Group Length in pixels. A value of zero will be ignored, so the previously set Group Length will remain unchanged. Refer to page 16 for further reference.

Set Pattern Replication Method : This parameter is configured to support 12 different methods of extending the Keyframe pattern over the length of all pixels controlled by a CPP driver. The first 4 methods are currently assigned. The remaining 8 methods are not yet designed, and selecting one will default to method 1 (Incremental). A Replication Method is always active. When using a 170 pixel keyframe, replication will apply from the 171st pixel through to the 500th. Data for all 500 pixels is always there, regardless of how many real pixels are connected. Refer to page 17 for diagram and reference.

Advanced Features : The LumenDimPix is a multifaceted device for users of all experience levels. The
features below can be explored further at http://rc4.info/ or by asking us for help at support@rc4wireless.com:

• In addition to the pixel types referred to in this Quick Start Guide, the LumenDimPix can also control LPD8806 pixels, MY9231 pixels*, and Port B can control strings that read DMX data directly. New pixel types will be supported with firmware updates from time to time , all of which can be selected using DMX Remote Device Management (RDM).
• The LumenDimPix includes RC4 ColorMatch™, allowing you to visually match the color rendering of different pixel strings. This lets you use multiple string types, brands, and batches that do not inherently look the same, and correct their output for better color continuity.
• Using a small adaptor cable, the LumenDimPix can be used as a wireless data receiver to deliver DMX to other devices. It can also be used as a wired DMX pixel driver: the miniplug DMX port becomes an input when the device is not linked to a transmitter.
• DMX Remote Device Management can be used to select DMX start channel and pixel string type for each pixel port. The LumenDimPix support both wired and wireless RDM when used with an RDM-capable CRMX transmitter. (Future firmware updates, always provided at no charge, will provide access to RC4 Custom Pixel Profile™ parameters. Watch for firmware update announcements.)* MY9231 control requires a very small clock adaptor module between the LumenDimPix and the first pixel, available from RC4 Wireless.

Caring for Your LumenDimPix :

• The LumenDimPix 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 LumenDimPix, which is 6A. To drive larger pixel loads, connect the pixel power lines directly to your power supply or battery. A common ground is always required between the LumenDimPix and the pixels.
• 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 10A fuse, use wire that can safely carry 10A.
• The LumenDimPix should be kept away from excessive heat, cold, dust and moisture.
• Do not immerse in water or other fluids.

Failing to observe appropriate safety precautions can result in fire or other risk. RC4 Wireless cannot be held responsible or liable in such cases.
