This article explains how to reset a DIN PIXIE Rev B that is misbehaving, stuck in error mode, or no longer detected. It covers the quick data-loopback factory reset and the full recovery path of entering boot mode and reloading firmware through the ENTTEC EMU software, plus a video walkthrough of the whole process.

Check that you have a Rev B unit

This procedure applies to the DIN PIXIE Rev B only. It does not apply to Rev A. Check the serial number on your unit:

  • Serial number before 2358764: you have a Rev A. The latest firmware for Rev A is v1.20.
  • Serial number after 2358765: you have a Rev B. It must run firmware v2.0 or later.

Firmware v2.0 and later is not backward compatible with Rev A hardware. Do not load the Rev B firmware files below onto a Rev A unit.

Before you start

  • A computer with the ENTTEC EMU software installed. Rev B requires EMU version 23.10.17.8 or later; use the latest release. See Check your EMU version and upgrade to the latest.
  • The USB Type-A to Type-B cable supplied with the unit.
  • A short piece of wire to bridge the data output terminals.
  • If the unit still responds and you have standalone shows recorded on it, back them up first. ENTTEC strongly recommends backing up standalone shows before any firmware update.

Option 1: factory reset with a data loopback

The DIN PIXIE has no reset button. If the unit powers up but you want to return it to factory defaults, use the data loopback method:

  1. Power off the unit.
  2. Wire the data pins of the two output ports together with a single wire.
  3. With the data pins connected, power up the unit and keep the connection in place.
  4. The status LED turns red and the DIN PIXIE is factory reset immediately.
  5. Disconnect the loopback wire.
  6. Power cycle the device.

The full list of settings restored by a factory reset is in Pixel Controller: Resetting to Factory Default.

Option 2: boot mode and firmware reload

Use this when the unit is stuck, shows an error state, or is not detected by EMU. Reloading the firmware resets a DIN PIXIE that has stopped responding. First put the unit into boot mode:

  1. Wire both data output ports together.
  2. Connect the DIN PIXIE to your computer with the USB cable. The LED flashes red to indicate the unit is in boot mode.
  3. Launch EMU and select the DIN PIXIE. EMU will prompt you to open the boot page for firmware updates and maintenance.

Then load the firmware from EMU:

  1. In the Firmware tab, either pick the default firmware from the drop-down list or click Choose Firmware and browse to a downloaded firmware file.
  2. Click Update Firmware and let the update run. Do not remove the USB cable until it completes. Progress is shown on the page.
  3. When the update finishes, power cycle the DIN PIXIE.

Video walkthrough and firmware files

The video below shows the complete Rev B reset and firmware update process from start to finish. It uses two firmware files: a beta build that is uploaded first, followed by the final v2.1 release. Follow the sequence shown in the video.
