ARML Projector Configuration Guide

The projector in the ARML is the EKB Technologies E4500MKIIRGBHP-OXF DLP development module. It works "out of the box" by connecting it to a video source via the mini-HDMI port. We have customized the firmware by adding the ARML logo to the splash screen.

Loading the custom firmware

  1. On a Windows machine, download and unzip the firmware management tool archive, which includes the custom image.
  2. Run the "LightCrafter4500.exe" file from the E4500MKII\GUI directory.
  3. Connect the projector to the computer using a USB cable (the port on the projector is micro-USB).
  4. Select the "Image/Firmware" tab, and then the "Firmware Upload" sub-tab.
  5. In the "Firmware File" input, choose the "DLPR4500_v3.0.0-EKB-ARML.bin" firmware file from the E4500MKII\Firmware directory.
  6. Click "Upload".

Customizing the splash screen

  1. Follow step 1 and 2 above to run the firmware management tool.
  2. Select the "Image/Firmware" tab and then "Firmware Build" sub-tab.
  3. In the “Firmware File” input, choose the "DLPR4500_v3.0.0-EKB-ARML.bin" firmware file from the E4500MKII\Firmware directory.
  4. In the “Add Firmware Tag” input, give your firmware a name (e.g. "arml_custom").
  5. Click the "Change" button and select the desired image. It must have a resolution of 912x1140 and saved in a 24Bit bitmap file format. For an example, download the ARML logo bitmap file.
  6. Click “Save Updates” and save the new firmware file. Make sure to end its name with a .bin suffix (the GUI does not add the file extension automatically).
  7. Follow steps 3-6 above, but choose the file you just saved in step 5.
