View source for Display Network Requirements

=Introduction=
This guide outlines the network requirements for preloaded software and assists IT administrators in setting up products within their IT infrastructure.

{{Note|
:* Ensure the wireless infrastructure supports broadcast service and is enabled.
:* For a more stable connection, connect ViewBoard devices via Ethernet cable and client devices to the 5 GHz Wi-Fi band.}}

=Air Class=
Display quiz questions on a ViewBoard and allow up to 30 mobile users to submit answers remotely. Whether administrating single or multiple-choice questions, the ViewBoard will record the results of each device being used.

<div class="res-img">[[File:ViewBoard_Air_Class.png|700px|Air Class]]</div>

==Network Information==
* PC (Windows/Mac/Chromebook), mobile devices (iOS/Android), and the display need to be connected to the same network subnet.
* Port: TCP 8080

=AirPlay Service=
{{Note|Please ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).}}

<div class="res-img">[[File:ViewBoard_Airplay_Service.png|700px|AirPlay Service]]</div>

==Network Information==
'''Ports''':
:<i class="fas fa-chevron-right fa-xs"></i> TCP 51040, 51030, 51020 & 51010
:<i class="fas fa-chevron-right fa-xs"></i> UDP 5353 (mDNS to broadcast Airplay)
:<i class="fas fa-chevron-right fa-xs"></i> UDP random port with a range of 52000–53000 (Transfer audio; assigned by AirPlay protocol)

==How to Verify AirPlay is Broadcasting==
<ol><li>Ensure that your iOS device and the display are connected to the same subnet network.</li>
<li>Open the Control Center and select AirPlay Mirroring on the iOS device (e.g., iPhone/iPad).</li>
<li>Find a device prefixed with “Cast-xxxx”.</li>
<li>If “Cast-xxxx” is showing then this confirms that vCast is broadcasting AirPlay services.</li>
<li>Click on the broadcasted “Cast-xxxx” device to mirror your iOS device to the display.</li></ol>

=AirSync=
AirSync is a wireless screen-sharing solution that enables seamless screen sharing between a user’s device and ViewSonic interactive flat panel (IFP) displays.

<div class="res-img">[[File:ViewBoard_AirSync_Service.png|700px|AirSync Service]]</div>

On supported IFPs, AirSync is pre-loaded on the system and does not require additional installation. To connect with the AirSync on the IFP, it is highly recommended for target devices to use the AirSync sender for sharing. The AirSync Sender supports several platforms. Download the version that matches the OS of your target device.

==Network Information==
===Firewall Requirements===
To ensure proper operation, confirm that the firewall allows the following connections for AirSync and the AirSync client.

===Relay Connection===
Relay connections are used in scenarios where direct connections between devices are not possible due to network configurations.

====With Wildcards====
<ul><li>TCP 443 for '''*.myviewboard.cloud'''</li>
<li>TCP 443 for '''*.myviewboard.com'''</li>
<li>TCP 443 for '''*.viewsonic.com'''</li>
<li>TCP 443 for '''*.airsync.net'''</li></ul>

====Without Wildcards====
For firewalls that don't allow wildcards.
<ul><li>TCP 443 for '''airsync.net''', '''www.airsync.net''', '''airsync.viewsonic.com'''</li>
<li>TCP 443 for:
<ul><li>'''api.gateway.airsync.net'''</li><li>'''us-east-1.gateway.airsync.net'''</li><li>'''ap-northeast-1.gateway.airsync.net'''</li></ul></li>

<li>TCP 3478 for '''turn.myviewboard.cloud'''</li>
<li>UDP 3478 for '''turn.myviewboard.cloud''' (Optional)</li>
<li>Local UDP ports '''32768~61000'''</li></ul>

===Local Connection (Direct Connection)===
Establish a network connection directly between devices within the LAN without relying on external servers or services.
* TCP 5001

====Remote Screen====
* TCP 7000

====Video/Audio (WebRTC)====
* Random UDP ports in the range of '''32768–61000'''

====Local Connection (Direct Connection)====
Establish a network connection directly between devices within the LAN without relying on external servers or services.
* TCP 5001

====Remote Screen====
* TCP 7000

====Mirror====
AirPlay, Google cast, and Miracast do not require access to the Internet.
<ul><li>AirPlay, Google Cast
<ul><li>Does not work in different subnet/VLAN</li><li>Random UDP ports in the range of '''32768–61000'''</li></ul></li>
<li>Miracast
<ul><li>Use Wi-Fi Direct (WiFi P2P). Does not require wireless AP.</li></ul></li></ul>

===Notes===
Ephemeral port range on Android or Linux:
<syntaxhighlight>adb shell cat /proc/sys/net/ipv4/ip_local_port_range</syntaxhighlight>

====Limit WebRTC Port Range in Chrome====
Chrome policies (WebRtcUdpPortRange) can limit the range of local UDP ports used by WebRTC. Refer to setting UDP port ranges in the following page:
*https://groups.google.com/g/discuss-webrtc/c/S5yex8rNIjA

=Chromecast=
vCast supports native Chromecast screen sharing via the Chrome browser casting when the Chromecast feature is enabled.
{{Note|Please ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).}}

<div class="res-img">[[File:ViewBoard_Chromecast.png|700px|Chromecast Service]]</div>

==Network Information==
'''Ports''':
:<i class="fas fa-chevron-right fa-xs"></i> TCP 8008 & 8009
:<i class="fas fa-chevron-right fa-xs"></i> UDP 5353 (mDNS to broadcast CCast)

==How to Verify Chromecast is Broadcasting:==
<ol><li>Ensure that your Chromebook and display are connected to the same subnet network.</li>
<li>Bandwidth: At least 2–5 Mbps per user in a typical deployment. Latency should be less than 100 ms when pinging Google’s public DNS server at 8.8.8.8; for HD video streaming > 5 Mbps is required.</li>
<li>Access points:</li>
:For small deployments of under 30 devices, consumer-grade networking equipment is sufficient.
:For deployments greater than 30 devices or involving multiple rooms, enterprise-grade, centrally managed networking equipment is recommended.
{{Note|
:*It is recommended to use Wi-Fi 802.11n 5 GHz.
:*Please refer to a 5 GHz channel guide for a table on non-DFS channels in your country. In the USA, those channels are 36–48 and 149–165.}}</ol>

=Display=
<p>myViewBoard Display allows users to mirror their desktop wirelessly to supported interactive flat panels (IFP) and wireless presentation displays (WPD).</p>
<p>myViewBoard Display comes pre-installed on select ViewBoard hardware, but can also be installed manually on any IFP or WPD that runs Android 6 or higher.</p>
<p>Once myViewBoard Display is installed on an IFP or WPD, users will only need to use a compatible browser to start mirroring their device screen to the host.</p>
