This video shows you how to register a headend using the Product Registration Tool (PRT).

The PRT is accessed by logging into the Triax website -> Support   "Product Licenses"

The video is referring to extraction of the 'Equipment file'.
If in doubt please see this article : How To Extract Equiptment File From The TDX / TDH800

During the first 30 days of operation, the headend will be in Trial mode, meaning all license based features (IPTV-out, SNMP, PID management and more) are available and activated.

When registering a headend in trial mode, the first license key purchased and installed, should always be the "418100 Installation key".

This Installation key will end/terminate the trial mode (deactivate the trial license based features) and activate the headend.

The "418100 Installation key" is for free (no cost).

Please note, if you have configured IP-out using the trial licenses, the IP-out configuration will be lost when activating  the headend.

Please save the configuration file before activating the headend. This enables you to upload the saved configuration after activating the headend and keep the IP-out configuration.

If you chose NOT to end the trial mode/activate the headend, the headend will reboot on day 31.

After this reboot the trial based features will be deactivated and an "activate reminder" will show up upon every login.

The headends basic functions will be OK and functional.
