Micro SD Card Slot

Programming instructions and media files are stored on a Micro SD card. Media files placed on the root of the card will autoplay upon power-up. Ensure custom programming remains on the card when updating video files.

Serial Communications

Control Port (RS-232)

The MH2-4K can send and receive serial commands via RS-232 at any baud rate configured in BrightAuthor. The port is an RJ45 jack, with adapter cables available for 3.5mm or DB-9 serial ports. A switch allows setting the port for Null or Straight configuration.

Control Bus (RS-485)

The RS-485 control bus enables interaction with devices such as Audio Authority TouchSelect panels or the 1895 Visual Volume knob. It can also control linked switch modules or amplifiers. The MH2-4K operates as unit ID 0, responding to commands addressed to this ID. Commands are echoed on both the RS-232 control port and the RS-485 control bus.

Example System: Sound Bars

The MH2-4K enhances engaging sound bar demonstrations by coordinating complex audio, video, and lighting effects. It allows customers to audition sound bars, select media, add rear speakers, compare TV speakers with sound bars, and adjust volume. A push-button initiates a sound bar demonstration, plays the first media file, and activates shelf lighting, including highlighting the selected subwoofer. Media selection is managed via a small touch screen. Rear speakers are powered by a smart amplifier that synchronizes volume with the selected sound bar. Upon inactivity, the display reverts to a silent state, ready for the next customer.
