A suitable driver may already be installed through other equipment, but reinstalling it is generally fine. Windows 11 users should use the Windows 11 installer below.

Connections and compatibility
Windows software: USB control requires the Windows software and a suitable USB driver. Running this software on a Mac through Windows compatibility software has been successful in some cases, but is not reliable or guaranteed. There is no dedicated macOS or iOS control application.
Browser control: On models equipped with a LAN browser interface, Windows 11 with Chrome or Edge gives the most reliable browser control based on our experience, particularly over wired Ethernet. Other browsers and platforms may work, but reliability varies. Apple devices have shown more compatibility and communication issues, and reliable operation cannot currently be guaranteed. Wi-Fi connections can be less stable and may require reconnecting if communication is interrupted.
Technical support and spare parts
Technical support is provided for the UK and Europe only. Outside this area, please contact your retailer.
