DMX Core Pico 2 Re-Mapper

Ever needed to re-map DMX channels in an installation? Maybe you don’t have access to the original programming and now you have a new light fixture with a different profile. This controller can hook up on your DMX line and re-map any of the channels. For each output channel you can configure which input channel it should take data from, or if it should be a fixed value.

Configuration is stored in the onboard non-volatile flash memory and can be easily updated by connecting the controller to your computer via USB-C. Powered via USB-C, or 7-28 VDC. Built on the DMX Core Pico 2 so you could even replace the firmware with your own.

Purchase Information

See the DMX Core Pico product page for specs and pricing. You can buy the Re-Mapper from dmxprosales.com, and it is also listed on our Amazon and eBay stores.

Features

DMX features

  • Refresh rate follows input
  • Per-channel configuration:
    • Straight channel to channel
    • Channel X to Y
    • Split any input channel to multiple output channels
    • Fixed output value

Digital Input

The 4 digital inputs can be configured to drive DMX channels, even when there’s no DMX input to the re-mapper. This can be used as a simple setup with up to 4 push buttons driving light fixtures.

Digital Output

The 4 digital outputs are connected to DMX channels 1-4 on the DMX input. Any time one of those channels goes above 127 then the output for that channel goes high. This can be used to drive relays and other equipment directly from DMX.

Configuration

Configuration via a signed, text-based configuration tool on Windows or Mac, connected over USB (see releases and Config Utility). Configuration is stored in a dedicated part of the 2MB flash memory. The config utility allows you to download/upload settings and store/load into YML text files locally on your computer.

Hardware

The Re-Mapper solution is software (firmware + configuration tool) that runs on the DMX Core Pico 2 hardware. Digital inputs, digital outputs, the USB UF2 bootloader, and the J3 SWD debug header are part of that hardware; see the Pico 2 pin out and software pages. A Raspberry Pi Debug Probe connects directly to J3.

Mounting

  • Wall/surface
  • DIN rail

Power

  • USB-C (USB-A to C cable included)
  • 7-28V DC via power input block (reverse polarity protected)
  • Typical power consumption is 30mA at 12V, less than 1 watt

Limitations

  • Output is driven by the input - without a DMX input, nothing will be sent on the output. However, when the digital inputs are used, a 40 Hz output is generated.
  • Since the device is in-line in the DMX stream, it introduces latency of about one DMX frame (~25ms). It reads the full DMX frame, runs the mapping, then sends out the frame on the output port. The latency is consistent on each frame.
  • RDM data is not passed through the device.
