Updating Your Equipment

• Insert the SD card to controller while controller is turned off

• Turn on the controller. A popup should appear indicating that ‘Firmware SD card is detected’.

• Follow the onscreen instructions to upgrade firmware.

• Once complete the Controller will power down.

• Connect the entire system. Reboot the controller and confirm the firmware has been applied under Menu>Settings>Software Upgrades

• Once confirmed, select Check for updates. If any updates are available for the connected ROV and accessories, you will be prompted to update by following the onscreen instructions.

Troubleshooting:

If the popup ‘Firmware SD card detected’ doesn’t come up when starting the controller with the SD card inserted, it is possible that the SD card has a problem. In this case simply try another SD card (preferably a different kind of card).
