The driver can be tested without license for 45 days with 25 lines. After the trial period, the lines can no longer be controlled and monitored. You can purchase license keys that unlock the driver permanently. To purchase licenses, contact your dealer.
The driver can be configured any number of lines. Opening a line consumes a license. If the existing licenses are used up, opening further lines will fail.
If you have configured multiple driver instances, all instances share the licenses entered. You can consume licenses anywhere on different instances.
