Abstract: Certain aspects of the present disclosure are related to a signage device controller. In certain embodiments, the signage device controller has: (a) a processor, (b) a network interface controller, (c) a communication control point in accordance with a control protocol and (d) a memory containing firmware. The firmware is configured to, when executed at the processor, (a) be in communication with managed signage device through the communication control point, (b) receive, through the network interface controller, a management request in a communication protocol from a remote management system through an out-of-band network for instructing the firmware to perform a management operation at the managed signage device, and (c) construct a control command in accordance with the control protocol and send the control command to the managed signage device through the communication control point to instruct the managed signage device to perform the management operation.
