Note: Atlona strongly recommends firmware updates using the Atlona Management System (AMS) or the unit’s web GUI. Firmware can also be updated via USB from a PC with Windows 7, or a Mac running Windows 7 in Bootcamp.

AMS allows management and automation of firmware updates for multiple Atlona IP-controllable products in an AV installation. With AMS, you can push new firmware to several devices at once, and also schedule updates at a convenient date and time.
