The XML files are for use with Firmware Upgrader Version 1.3.0.1

The files will update any 3000 variant to the latest firmware (IRC3010, IRC3020, IRC3030, etc)

Use the Universal Upgrader files for all counters.

If instructed by the Universal upgrader, you may have to upgrade very old units using the PreUpgrader first, then the Universal Upgrader afterwards. This is only required for very old units.

Once started do not attempt to stop an upgrade.

Always upgrade masters and connected nodes at the same time.

All IP enabled units must be upgraded via an IP connection only - do not use serial. Relay enabled units must be upgraded via serial.
