Remove the Ethernet Cable from the Nexus Lite Controller and connect it to the OMNIA Lite Controller. The APC controller will need to have the Dips Set to 0100 ( 1 off, 2 on, 3 off, and 4 off).

If there were any iTRT’s connected via RS485, move the RS485 connection to the OMNIA Lite Controller.

When the OMNIA lite controller is found, Click on the controller, Click on the Backup Tab, Then click restore.

Select the Location of the Nexus Lite Backup, Click Open

The backup will begin. You will receive a Device Discovery Failed message. This is normal because the Backup is changing the IP address of the OMNIA Lite Controller to the previous IP Address of the Nexus Lite Controller and the OMNIA Firmware Upgrade Utility is not finding it at the old IP address.

In the lower left of your PC you will received a message that the restore is complete.

When you use the OMNIA Lite Firmware Upgrade Utility, you will find the OMNIA Lite Controller. Notice the Controller’s name changed from OMNIA Lite to Nexus Lite, the MAC address is the MAC of the OMNIA Lite Controller, and the IP address is the IP address of the Nexus Lite Controller.

NOTE:  The Nexus Lite name change is due to the Backup and does not affect the OMNIA Lite Controller.

After the backup is complete, you will need to log into OMNIA lite, update the time, run discovery and swap the reader terminals from NexusLite Board Fixed Addresses to the Wiegand Reader Modules Fixed Addresses.
