The Digital Signage Management Communication Client secures the communication between the Digital Signage Management plugin and digital signs.
Because of the protocols used by the panels, the communication between the DMS plugin and the panels is unsecure and should not happen over a public network. The Digital Signage Management Communication Client establishes a secure connection between the Digital Signage Management plugin and Windows service over public network, then it will communicate directly with the panels using the unsecure protocols locally.
