biamp Crowd Mics ATOM Cornerstone

Network Administrator’s Guide

Crowd Mics is an audience engagement system comprised of a mobile application and form factor computer called the ATOM. The application allows attendees of an event, such as a lecture or a company meeting, to use their phones as a wireless microphone. It also allows text commenting viewable by a moderator as well as live polling.
This document is intended to guide network administrators and IT teams in successfully integrating a Crowd Mics system within a network environment.
ATOM Network Characteristics
The ATOM has the following external connections for networking and A/V:

Dual 100/1000Base-T Ethernet ports
2x HDMI connections (mirrored)
Dual USB 3.0 ports (Type A)
1/8” unbalanced audio out
Euroblock connector (balanced audio out)

Network Prerequisites
The ATOM and all mobile devices (moderator and participants) must be connected to the same WLAN, and must be in the same subnet address range in order to receive multicast inter-device discovery data.

Each device must have an IP address provided by the WLAN, assigned via DHCP by default or via Crowd Mics configuration software or API.
IP addresses are based on IPv4 (IPv6 not supported).
Network Ports
Some communication ports might be locked by default, typically for security reasons in routed or restricted network segments such as public wireless access for guests. For optimal operation of Crowd Mics, ports in the table that follows should be open and without restriction for the duration of the Crowd Mics event.
Network Connection and Performance
Due to the potential that dozens of users will connect to the same WLAN to participate in an event, Crowd Mics should be deployed on a professional, enterprise-grade wireless network to ensure optimal reliability/connectivity during an event.
Deployment
An open WLAN between participants and the presenter is the recommended method to deploy Crowd Mics. This entails the participants’ and moderator being on the same wireless network/subnet and uninhibited communication on any port.

Configuration Details

IPv4 WLAN for moderator and participants
Bonjour/mDNS allowed in the WLAN
Client isolation/peer-to-peer blocking disabled (allow ‘any-to-any’ communication among devices on the WLAN.)

This configuration allows direct communication between the participants and the moderator.
Physical Connections

Ethernet Ports – Control and User Networks
USB 3.0 (Type A)
HDMI
Euroblock Audio Connector
1/8” (3mm) unbalanced Audio Out
Power

Connect power to the ATOM.
Connect HDMI, 1/8” balanced audio ports, USB and/or the Euroblock connector to the venue’s A/V system. These connections may be used simultaneously in any combination.
Connect the user Ethernet network port to the venue’s Wifi system. On the user side, the protocols are a combination of mdns-sd, webrtc, and http. Mobile devices will find the
ATOM via mdns over wifi. atom. local broadcasts on the user port.
The second Ethernet network port is optionally used for control via SageVue and may be connected to the corporate LAN. The protocols on the control side are https and http.
Either port may be configured for network or control, but for consistency it is recommended that Port 1 be used for management (control) and Port 2 be used for connecting to the wireless network.
Both ports are on independent NICS, they are not switched, and the ATOM has been penetration tested to ensure isolation of the two ports. Once all connections are made, power up the ATOM.
Diagrams on the last page of this document give typical network connection examples.
ATOM Configuration
The ATOM is designed to deploy ‘out of the box,’ with no configuration needed, but is equipped with an advanced setup feature which allows users to access more advanced configuration options via a dashboard.
Make all physical connections described previously. Connect to the ATOM configuration dashboard via a PC on the same subnet with the following URL:
https://atom-XXXXXXXXXXXX.local
X’s represents the MAC address of the ATOM and may be found on a label on the underside of the ATOM:
Alternatively, a user may navigate to the dashboard page via the IP Address if it is known.
A log in screen requires the following case-sensitive default credentials:
- Username : admin
- Password : first four and last four characters of the device serial number.
- IMPORTANT : Any letters in the device serial number must be entered in lowercase.
From the dashboard, users have the option to make adjustments to audio levels, assign a custom name to the ATOM, change log-in credentials and change network preferences.
Users may also connect to the ATOM via SSH while on the same subnet.
Alternatively, users may log into a terminal session directly on the ATOM. This requires direct connection of a keyboard and monitor to the ATOM.
Only one ATOM may be routed to a particular

Mobile Applications
There are two Crowd Mics mobile applications: one for the moderator and one for the participants. Participants should be informed in advance of the event in order to download the application. The moderator should set up any polling questions prior to the event. Use the following QR codes to download the mobile applications.
