Communication

The MH10-ARC Intelligent Audio 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 via RS-232 at 115200 Baud, 8-N-1, and full-duplex. Both configuration ports utilize a modular RJ45 jack with the following pinouts:

RS-485 Pinout:| | | RS-232 Pinout:| |
---|---|---|---|---|---
Pin| Function| Pin| Function| | Pin| Function| Pin| Function
P1| Orange White (ground)| P5| Blue White (+12V power)| | P1| Orange White (ground)| P5| not connected
P2| Orange (ground)| P6| Green (data B-)| | P2| Orange (ground)| P6| Green White (RX/TX)
P3| Green White (data A+)| P7| Brown White (ground)| | P3| Green White (TX/RX)| P7| Brown White (ground)
P4| Blue (+12V power)| P8| Brown (ground)| | P4| not connected| P8| Brown (ground)

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 devices.

HDMI-ARC
HDMI Audio Return Channels (ARC), controlled by the MH10-ARC, 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 embedded audio on the video output port.

Quick Start Instructions

Create a new BrightAuthor experience for the HS123/124/144 (depending on the module installed in the MediaHub).
In BrightAuthor’s presentation properties on the interactive tab, ensure “port 0” is configured to a baud rate 115200 8-N-1, ASCII, with “CR” for send and receive EOL.
Create your presentation. Note that any built-in serial or GPIO port is treated as a serial device, following the applicable MediaHub serial protocol.
Export your presentation to a microSD card and insert it into the mediaSD port.
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

MH10-ARC with 10 Sound Bars and Indicator LEDs
This configuration uses HDMI audio return channel to demonstrate sound bars. Ten audio outputs can play either HDMI-ARC, or optical digital and analog audio, depending on the requirements of the device. It leverages the MH10-ARC module’s dedicated 4K display output to invite and attract customers. The Ethernet port interfaces with the network to receive commands and output analytics; with the added capability to control and monitor the system remotely. Ascentic-MH10-ARC-Intelligent-Audio-
