USB driver

Windows USB driver installation

Installation Guide

Note! Run the installation file as administrator.

→ Right mouse button → Run as administrator
→ Extract
→ Next
→ I agree to the license agreement → Next
→ Finish

The USB driver is now installed and ready for use.

The USB2DMX interface can now be plugged in.

The file is available as Windows ALL IN ONE driver 2.12.

macOS Helper instructions

As of macOS 10.9, Apple locks the driver out at the factory level - i.e. the required driver is installed but can't be used.
The macOS Helper fixes this until Apple resolves the issue in a newer operating system version.

Note! The USB2DMX® interface is not yet plugged into the USB port.

Start the macOS Helper
→ Open With → Installer
Continue
Install
Enter your macOS user password . → Install Software
Info Please wait until the installation is complete. This may take 1-2 minutes.
The installation has completed successfully → Close
→ Apple → Restart

Important! Be sure to restart your computer for the changes to take effect.

The macOS USB driver is now unlocked.

The USB2DMX interface can now be connected to the USB port.

Linux USB driver installation

On Linux the driver for the built-in FTDI chip is already part of the system. So there is no driver file to download and nothing to install — only the access rights to the serial port are missing.

Plug in the DMX interface and check in the terminal whether the system has detected it and assigned it to a port such as ttyUSB0.
dmesg | tail
Then run this command to give your user the access rights it needs for that serial port.
sudo usermod -a -G dialout $USER
Finally log out completely and log back in so that the new permissions take effect.

Note! Restarting the terminal alone is not enough — group membership is only applied when you log in.

The USB2DMX interface is now ready for use.

Android USB driver installation

A separate driver installation is not required, because our apps already have the necessary drivers fully built in.

Note! That is why there is no Android driver file on the download page — none is missing, there is none.

In this case, check the entry and pay attention to upper and lower case as well as underscores / hyphens and spaces.
Avoid special characters.
Don't use a password manager or AutoFill - these functions can unintentionally set the wrong password.

As long as the WIFI LED is flashing red rapidly, you can reconnect to the AIR2DMX interface via your WLAN end device and make the necessary setup corrections.

ArtNet HotSpot Mode

Apparently no reaction in HotSpot mode

Note! Deactivate mobile data

In HotSpot Mode, mobile data (WIFI+) must be disabled on the smartphone / tablet.
The AIR2DMX interface cannot provide access to the internet.
Most mobile devices then try to connect to the internet via the cellular network or other WiFi routers.
This means that the AIR2DMX WLAN interface is temporarily or permanently unavailable.
