Changing IP addresses on multi-unit systems

Default IP address

All Nexia and Audia devices are shipped with a default IP address of 192.168.1.101.

On single unit systems you can start programming without changing the IP address. For multi-unit systems, each device must have a unique IP address.  Therefore, the IP addresses need to be changed so all units can co-exist in the same network.

Modifying multiple IP addresses

To change the IP addresses on a multi unit system, follow these steps:

1. Connect to the system to retrieve the current configuration file.
   • Ensure the IP address of your PC is in the same subnet as the IP address of the devices.
   • Go to File→Network→Connect to Network to discover the devices on the network.
   • Select a system from the System List, and click Connect To System.
2. Disconnect from the system and save a copy of the file in your hard drive.
   • Go to File→Network→Disconnect from System.
   • Go to File→Save As...
3. Reset/Initialize all the devices in the system to clear out their configuration file.
   • Go to File→Network→Perform Device Maintenance
   • Select a device in the Device List, then click Reset/Initialize
   • Note that the device ID will change to 0 once the device has been reset.
4. Change the IP addresses of all your devices.
   • In the Device Maintenance window, select a device in the Device List, and click Set IP Address.
   • Enter the desired IP Address, Subnet Mask, and Default Gateway and click OK.
   • Note that units might disappear if the new IP address is in a different subnet.
5. Rediscover the devices at their new IP addresses, and resend the configuration file.
   • Close the Device Maintenance window.
   • If the devices are now in a new subnet, you will need to change the IP address of your computer to be in the same subnet.
   • Go to File→Network→Disconnect from Network.
   • Go to File→Network→Connect to Network.
   • Click on the Send System Config button.
