About the Product

Sennheiser MobileConnect is an Assistive Listening solution. The system streams audio content via

WiFi live and in superior quality to any mobile device. Following the Bring-Your-Own-Device concept,

it is an easy-to-use and intuitive Assistive Listening system. Costs and maintenance effort for

operators are kept at a minimum. MobileConnect is optimized for use in higher education institutions.

The MobileConnect system consists of three components: the MobileConnect Station, the

MobileConnect Manager, and the MobileConnect App. The MobileConnect Station is integrated into

the existing campus network and distributes the audio content via WiFi to the MobileConnect App on

the user's personal smartphone. With the MobileConnect Manager, all MobileConnect Stations in the

network can be conveniently administered and remotely managed from anywhere on the campus.

Quick Setup

You can configure the MobileConnect system in 5 steps:

MobileConnect User Guide for the IT Administrator

Version 1.5

Step 1. Configure your network

You can use one single network or two separate networks for streaming and control (for more see

section Network Setup). In both cases, you need to configure the following in each network:

DNS

The system needs a single SRV record of _mcal._tcp per network, which points to the MobileConnect

Manager. You need to provide your own DNS server. The following example shows the configuration

needed for a DNS server, adapt it to your DNS server in use.

Service Name

TTL

Class

Type

Priority

Weight

Port

Target

_mcal._tcp.yourdomain.com

3600

SRV

8000

mc-manager

.yourdomain.com.

mc-manager.yourdomain.com

3600

IP address of mc-

manager

•Replace "yourdomain.com" with your own domain

•Use FQDN and not a direct IP address for the SRV “Target”

•The target hostname "mc-manager" can be replaced with any hostname you want to give to

the MobileConnect Manager. Above you can see an example of the A record.

DHCP

The following DHCP settings are required so that the MobileConnect Apps and the MobileConnect

Station can discover the MobileConnect Manager:

•For Android →configure the "Domain name" option of the DHCP protocol (DHCP Option 15).

Android ignores the "Search Domains" option (DHCP Option 119).

•For iOS →if you only use one search domain, set the "Domain Name" option of the DHCP

protocol. If you use multiple search domains, the domain must be also set in the "Search

domains" option.

•The MobileConnect Station respects both options "Domain Name" and "Search Domains".

Version 1.5

Step 2. Configure your WiFi

Configure traffic prioritization on your Access Points:

•streaming uses DSCP EF value

•control uses DSCP CS3 value

Step 3. Install the MobileConnect Manager

The MobileConnect Manager is a dockerized application which you need to install on a Linux server,

accessible in your network. It runs on Linux x86-64 (amd64), Ubuntu 20.04.x, the steps provided

below are for this Ubuntu version.

A. First, select your hardware:

Minimum hardware requirements

•CPU with 4 cores

•Regular (not boost) clock speed on all cores at least 2.4 GHz

•8 GB of RAM

•200 GB of hard drive space

Recommended hardware requirements

•CPU with 8 cores

•Regular (not boost) clock speed on all cores at least 3.0 GHz

•16 GB of RAM (or more)

•500 GB of hard drive space

Without prioritization you cannot achieve good audio quality and low latency.

We strongly advise not to use MobileConnect without it.

The MobileConnect Manager requires Internet access for its installation as well

as operation.

•Add your user to the docker group and reboot.

•Enable the docker service to start at boot.

E. Obtain the MobileConnect Manager installation package:

•First you need to create a MobileConnect account as described in Create an Account.

•Then register and obtain your Manager following the steps in Register a Manager.

F. Install the MobileConnect Manager:

•Create an installation directory with a name/path of your choice. We recommend

installing as a normal user in your home directory.

•Copy the MobileConnect Manager installation package which you obtained in the

previous step to the installation directory.

•Enter the directory.

•Extract the archive.

Version 1.5

•Set your database password as local environment variable.

oIf you use special symbols, make sure the password is enclosed with

single quotes.

oAn environment variable is set, run all docker-compose commands in the

same terminal.

oMake sure you keep the password. You will need to export it for every call

to docker-compose you do (for example when starting or shutting down

the Manager or when upgrading the MobileConnect Manager in the

future).

•Install and run the MobileConnect Manager with:

•Wait for 3 to 5 minutes until the initialization of the MobileConnect Manager is

completed.

•Open a browser and navigate to the URL you configured for your MobileConnect

Manager, e.g. https://mcmanager.yourdomain.com.

oThe MobileConnect Manager web interface is using a self-signed

certificate, you need to accept it to access. You can install your own

certificate, for more information see Installing a Custom SSL Certificate.

oCurrently the Manager supports the Chrome and Firefox browsers.

•Login with the credentials you used when registering your account (see Create an

Account). The MobileConnect Manager is now ready to use.

The password must be at least 8 characters long and contain characters from

three of the following four sets: Uppercase letters, Lowercase letters, Base 10

Digits and Symbols.

Step 4. Install the MobileConnect Station

There are two versions of MobileConnect Station (MCS) hardware:

MCS v1

MCS v2

•Connect your MCS to the network

oUse LAN2 (MCS v1) or PoE/Stream (MCS v2) port to connect your streaming

network.

oUse LAN3 (MCS v1) or Ctrl (MCS v2) port optionally to connect a second network for

configuration. If you do not wish to use a separate network, and the port is not

connected, the system will use the streaming network for control as well.

oNote: The network ports use DHCP by default. To configure a static IP using the local

admin interface see Configure Your Station Using the Local Admin Interface.

•Connect your audio inputs

oFor MCS v1 you can connect any of the four analog inputs.

oFor MCS v2 you can use the analog or Dante inputs.

•Power on

oFor MCS v1 press the power button.

oFor MCS v2 connect the PoE port.

•Check the MobileConnect Station in your Manager web interface.

oOpen the MobileConnect Manager interface (e.g. at https://mc-

manager.yourdomain.com or https://your-manager-hostname).

oYour MobileConnect Station should be shown in the Stations list.

▪Depending on the firmware version you may be required to update it and

authorized it. For more information see Security & Authorization.

•In case of problems, see section Troubleshooting.

In order to use a MCS v1, you need to upgrade its firmware. For details, see section

Upgrading a legacy MobileConnect Station.

For more advanced features see section Manager and Station configuration.
