Creating your account and add your Pearl Controller to it

Creating your account and add your Pearl Controller to it

In most cases, your Link4 system shipped from the factory preprogrammed.  We created an account for you and connected the system to it already.  There should be attached instructions to your system with a temporary login credentials and a 30-day trial activated already.  Most systems come with an quick factory acceptance video showing your system in operation, and, if appropriate a PDF of your drawing attached to your cloud.  However, should you need to create a new account and attach a new Pearl to it, please follow the instructions below.
Warning
Note:  For security reasons, once a controller has been associated with an account, it cannot be associated with another
account.  Please contact Link4 if this has to be changed for some reasons.  Your identity will need to be verified.
The new account and controller association is a 3 step process:
  1. Connect your controller to the cloud and locate the Cloud ID on the controller.
  2. Create a new account on c2.link4cloud.com .
  3. Enter the Cloud ID (in step 1) as a new Gateway in your cloud account (in step 2)
