Playback, networking and backup
Use LAN, Wi-Fi or a USB flash drive to transfer or play content as described in the manual. 4G is an option, so confirm the module, antenna and mobile-network requirements for the supplied unit.
Do not add the LED OUT and BACK UP ratings together to assume a larger independent display canvas. The document identifies one connection for display and one for backup, but also lists a different total in its feature section. Confirm supported loading and port mode before ordering.
The original description lists broad media and content categories without codec-level requirements. Test the actual program and media files before deployment. Sensor support identifies connection capability; confirm the required sensors separately.
