LumenDimPix Dual Pixel String Driver for CRMX

Product Code RC4-LumeDimPix
Manufacturer RC4 Wireless


Product Details

The RC4 LumenDimPIx is a tiny wireless DMX driver for pixel LEDs  on the CRMX platform that enables designers to create beautiful effects quickly and easily while using fewer DMX channels. The LumenDimPix can control two separate strings up to 500 pixels long — the equivalent of 3000 DMX channels — using 3 to 510 channels within a single DMX universe. This is done using RC4’s patented Custom Pixel Profiles. Designers can create unique and entirely original eye-catching effects and visuals without the use of complex multi-universe consoles, media servers, and all the wiring that goes with them.  Using RC4 OneTouch™, RC4MagicPC Remote Configuration Software, or wired RDM, users specify the string type, the DMX start channel, and various configuration parameters for each driver.

DMXpix_PLASA2015_1_psEach designer has their favorite pixel string, and new products appear every day.  However,  few professional-grade drivers are built to control multiple string types, aka chip protocols.  The LumenDimPix is the most versatile product possible, supporting all popular protocols, including WS2801, WS2812, APA102, LPD8806, MY9231 and numerous others.

As chip technology changes and advances, so does the LumenDimPix. The RC4 Wireless CodeLoader allows drivers for new pixel products to be added by simply downloading and installing them.

The LumenDimPix includes a standard DMX data port and an I2C interface for use with Arduino, Raspberry Pi, and more. Also note that any number of receiver-dimmers can be used in a LumenDim system, including multiple LumenDimPix devices.

Traditional mapping of DMX to pixel strings consumes vast numbers of channels — a single universe of 512 channels can control only 170 red-green-blue pixels.  At the same time, many lighting designers use pixels for repeating patterns along a string, and to emulate separate lengths of traditional LED tape from a single string.  Patented RC4 Custom Pixel Profiles, using keyframes, deliver the same design versatility and control to designers, while vastly reducing the number of console DMX channels required to render unique effects using up to 1000 pixel LEDs.  In effect, Custom Pixel Profiles moves channel duplication out of the console and into the pixel driver itself.

Color matching can be challenging, most especially when dealing with pixel strings from different manufacturers.  RC4 ColorMatch™ enables designers to adjust the color balance of each string to ensure a consistent palette, even when combining products from different manufacturers, different control protocols, and differences due to variations in LED binning.  Pixel Color Order ensures all pixels in a large system will address colors with the same sequence, usually red, green, blue.  By off-loading color correction and pixel color order to the pixel driver, rather than managing this in a console or media server, multiple different pixel strings can be controlled from the same DMX channels without unsightly color variation.

To make the LumenDimPix the ultimate DMX data conversion and control device, a DMX data in/out port is also provided, along with an I2C interface for use with Arduino, Raspberry Pi, and most other micro controller systems. Using the DMX port as an input, the LumenDimPix can be controlled by wired DMX with extensive RDM (remote device management) support.

The internal wireless DMX receiver operates identically to the LumenDimIO in receiver mode.  The RC4 DMX mini-plug port can used with a range of DMX adapters, including 3-pin and 5-pin male and female XLR connectors.  The most common adapter is the RC4DMX5FA with 5-pin female XLR connector.
