Content Control and Installation Checks
The player supports content publishing and screen control from a PC or supported third-party client platform, including remote group management and status monitoring. A local terminal can connect to its built-in Wi-Fi AP. USB playback provides an additional content option.
The maximum width and maximum height shown above are separate configurations. They do not establish support for a 1280 × 512 display. Check the cabinet layout, module pinout and total loading before replacing an installed card.
The RS485 interface can connect to a compatible light sensor or function module. The relay provides switching control; its rating is separate from the player’s DC input voltage. The original specification advises against using the player relay to control AC directly and provides a recommended connection diagram for that application.
