Introduction
The MH10-HD MediaHub uses the latest audio technologies
to showcase HDMI audio products with multi-channel surround
sound. The presentation and user interface behavior may be fully
customized using ARC, CEC, and the built-in power of Brightsign
with Bright Author.
Features
• Play native content for HD audio-video presentations
• Routes HDMI and/or HDMI-ARC signals across 10 outputs
• Enable and disable video and/or audio signals on each HDMI output via serial commands
• Discrete audio outputs deliver analog, digital, or both audio formats simultaneously
• Connect touchscreens, up to 20 push buttons, or touchless sensors to control interactive presentations
• Atmos / DTS-X

Communication
The MH10-HD MediaHub has the default device ID 253. It can send and receive serial commands via RS-485 at 57600
Baud, 8-N-1, and half-duplex; and by RS-232 at 115200 Baud, 8-N-1, full-duplex. Both conguration ports utilize a
modular RJ-45 jack with the following pinouts:

CEC Communication
The MH10 series manages CEC (Consumer Electronics Control) communication between the BrightSign host and any
of the 10 HDMI outputs. The MediaHub employs a separate micro-controller to manage CEC and correct discrepencies
between the protocol of different connected products.
HDMI-ARC
HDMI Audio Return Channels (ARC), controlled by the MH10-HD, support from 2.0 up to 5.1 channel PCM. The number
of PCM channels is decided during programming. Control your presentation via the media microSD card. Content played
via PCM can be played in conjunction with HDMI embedded audio.
Embedded Dolby Atmos and DTS-X Audio
The MH10 series supports embedded audio to play Dolby Atmos and DTS-X, custom tayloring your presentation based
on the capabilities of the device (up to 7.2 channels). The ability to play Dolby and other formats simultaneously is what
sets the MH10-HD apart from other media players. This type of programming is controlled by BrightAuthor programming
and the native media on the microSD card.
Quick Start Instructions
1. Create a new BrightAuthor experience for the HS124 (depending on the module installed in the MediaHub).
2. In BrightAuthor’s presentation properties on the interactive tab, ensure “Port 0” is congured to a baud rate 115200
8-N-1, ASCII, with “CR” for send and receive EOL.
3. Create the presentation. Note that any built-in serial or GPIO port is treated as a serial device, following the applicable
MediaHub serial protocol.
4. Export the presentation to a USB or microSD card and insert it into the MediaHub content port.
5. Connect any peripheral devices, followed by the power supply. EDID should be routed to an HDMI device or to the
internal “SELF” table.

Example System
MH10-HD Demonstrates Eight Sound Bars and Two TVs
This demo uses audio and video to showcase HDTVs in full HD and multi-channel surround sound for sound bars.
It leverages the MediaHub’s CEC switching capabilities to demonstrate multiple HDMI(-ARC) products. Discrete audio
outputs can play either digital or analog audio in tandem with the content on the HDMI outputs. The Ethernet port interfaces
with the network to receive commands and send analytics; with the added capability to control and monitor the system
remotely. Power the MH10-HD using the included DC power adapter.

• Ensure that the HDMI-ARC device is turned on and
connected to the appropriate port
No HDMI Audio/Video (non-ARC)
• Ensure that the HDMI HPD is disabled for the position
• Ensure that the HDMI 5V Output for the position is
enabled
• Ensure that the HDMI Video is routed to the position
• Ensure that the BrightSign is routed to an EDID device
(internal or external)
• Ensure that the BrightSign experience is sending
compatible audio via the HDMI interface.
• Ensure that the HDMI sink device is turned on and
connected to the appropriate port
No Ethernet Connectivity
• Ensure connections are fully seated
• Ensure the correct position is selected via software
