License Keys
Each computer in the system requires a WATCHOUT license key, including the production computer. Plug the key into any free USB port on the computer.

NOTE: Dataton WATCHPAX media servers have internal licenses, and don’t require any external license keys.
HINT: You can run the production software off-line without a license key connected. A key is needed when you go on-line to communicate with the display computers.
