Multiple rooms on one room key and Valid Start Date / Valid Start Time functionality is dependent on the DLS supporting it.
When more than one DLS interface is active at the property, each must be configured with unique room numbers and must support the same functionality. The correct encoder/terminal for the DLS must be chosen during the Create Key process.
Room key creation functionality shows the room key creation success or failure according to the DLS response.
If the DLS doesn’t respond within the timeout value set in the DLS property interface configuration, OPERA shows a message that the room key creation timed-out. If this occurs, you can retry creating the room key.
