Software update information for the Digitarium OP2 operating platform.

Note: All new operating system software was released for OP2 systems on April 3, 2012. This free upgrade brings OP2 systems up to parity with all more recent Digitarium operating platforms, other than hardware dependent features.

This upgrade is highly recommended and requires a manual download. Some older systems will require minor hardware upgrades first. Log in to the Digitalis Community website for instructions.

Once you have installed this upgrade, you will have an OP2B operating platform. The original OP2 platform is now deprecated by OP2B and therefore no more software updates will be released for the original OP2. View software updates for OP2B.
