Introduction
The MH10-HD MediaHub With HDMI Distribution Amplier uses
audio and video to showcase HDMI products in high-denition with
multi-channel surround sound. The presentation and user interface
behavior may be fully customized using the built-in power of
Brightsign and Bright Author.
Features
• Distribute identical HDMI signals across 10 outputs
• Play native content for HD audio-video presentations
• 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 push buttons or sensors to control interactive presentations

Communication
The MH10-HD MediaHub With HDMI Distribution Amplier 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
conguration ports utilize a modular RJ-45 jack with the following pinouts:

CEC Communication
The MH10 series is capable of routing CEC (Consumer Electronics Control) communication between the BrightSign host
and any of the 10 HDMI outputs.
Quick Start Instructions
1. Create a new BrightAuthor experience for the HS123/124/144 (depending on the module installed in the MediaHub).
2. In BrightAuthor’s presentation properties on the interactive tab, ensure “Port 0” is congured 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. Note that HDMI Port 1 will set the EDID information for
all other connected HDMI devices.

Example System 1
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 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.

Example System 2
Five Sound Bars and Five TVs
Five HDTVs in full HD resolution, and ve soundbars in multi-channel surround sound showcase the capacity of this
MediaHub. This conguration uses the ten HDMI ports to deliver audio and video signals and switching commands via the
CEC channel. When a push-button is pressed, the MH10-HD is programmed to send the specic CEC command to mute
or play the sound at that position. CEC commands must be programmed for each specic model of TV or sound bar. The
Ethernet port interfaces with the network to receive commands and send analytics with the added capability to control and
monitor the system remotely. Update the rmware and load content via the dual microSD ports.
