6.2 Obtaining a permanent licence

It is necessary to activate the RexCore runtime module and optional additional modules for permanent operation. This can be done using the licence, which you can obtain in an e-shop at

6.2.1 Activation of the permanent licence

The purchased licence must be associated with the hardware device.

Each device running the RexCore runtime module is identified by the so-called SiteID tag. You can get it in RexDraw or RexView when connected to the device. After connecting to the target device, go to menu Target Licensing.... A dialog pops up and you can copy the SiteID identifier.

Afterwards, login to www.rexcontrols.com using your username and password and list the available licences which you possess.

Use the SiteID identifier to associate the licence with the hardware device.

You are asked to confirm the association – this is the last and irreversible step.

PIC

The so-called SiteKey activation key is generated upon associating the licence.

PIC

This key will allow permanent operation of the runtime core, but it must be applied to the target device. To do that, open the licensing dialog in RexDraw or RexView again and apply the SiteKey using the Add button.

PIC

If the key is valid, the activated modules appear. The Raspberry Pi must be restarted afterwards.

After reboot, check that the licence was applied correctly and that the RexCore runtime module no longer runs in demo mode.
