Go to the ‘Setup’ page on the touchscreen by tapping on the icon that looks like a gear at the bottom right-hand corner of the touchscreen. Once you’re on the ‘Setup’ page, tap the ‘About’ tab.  All the firmware versions for the Main board, I/O modules, and any Option card you may have installed will be displayed in this tab.

To find out if you need to update firmware, power up the unit and connect it via Thunderbolt to a Mac with Symphony I/O MkII software already installed. A firmware mismatch dialog that directs you to the firmware updater app will appear if you need to update your firmware.

Note: A Symphony I/O MkII that has a Pro Tools HD Option card installed in it can only update firmware via the USB port on the back of the HD Option card.
