Firmware Updates

LYNX Technik provides free firmware upgrades for all customers.

We recommend using YelloGUI or LYNX Centraal to update Yellobrik devices, Serie 5000 cards and greenMachines. Create a Lynx Online Database account through YelloGUI or LYNX Centraal to see which of your connected devices qualify for a firmware update.

Testor updates must be applied manually. Check the version of your Testor Lite from the touch screen menu; navigate to HOME > Settings > System > Version
