ViewBoard®
Network Requirement
Introduction
These notes will introduce the network requirements for ViewBoard®’s preloaded
software and help IT administrators setup ViewBoard® products in their IT
infrastructure.
Ensure the wireless infrastructure supports broadcast service and is turned on.
To get a stable transmission, it is strongly recommended to have ViewBoard®
connected via an Ethernet cable, and client devices on a 5GHz Wi-Fi band.
Over-The-Air (OTA) service
ViewBoard® automatically searches for firmware updates whenever connected to
the Internet. With just one click or every time the ViewBoard is powered off, users
can update their version of ViewBoard® firmware.
Network information
• Server FQDN Name: ifp-ota.s3-accelerate.amazonaws.com,
www.viewsonicglobal.com
• Server Port: TCP 443
OTA Service
A dual band wireless access point
(5G) is preferred
After receiving the OTA (Over The Air)
notice, tap Settings → About → Device →
System updates to download new image
Connect to in-room wireless
access point via Ethernet Cable
After downloading, the device will
automatically upgrade and reboot

Display quiz questions on ViewBoard® and allow up to 30 mobile users to submit
answers remotely. Whether administrating single or multiple-choice questions,
ViewBoard® will record the results of each device being used.
Network information
• PC (Windows/Mac/Chromebook) and tablet/mobile (iOS/Android) devices, as
well as ViewBoard®, need to be linked to the same LAN network subnet.
• Ports : TCP 8080

vCastReceiver & vCastSender Service
Working with ViewBoard® Cast software, the vCastReceiver app, will allow
ViewBoard® to receive vCastSender laptop screens (Windows/Mac/Chrome) and
mobile ( iOS/Android) users’ screens, photos, videos, annotations, and camera(s).
It is also compatible with Apple AirPlay®.
Network information
• ViewBoard® Cast software, laptops, and mobile devices can connect to both
the same subnet and across the subnet network.
• Please enter the on-screen PIN-code to connect to the ViewBoard.

A dual band wireless access point
(5G) is preferred
Connect to in-room wireless
access point via Ethernet Cable
Connect to the same network (Local Area Network), select 5G
mode for optimal casting

Airplay Service
Please ensure that DNS is enabled on the network/access point/wireless
controller.
Network information
• Ports:
ො TCP 51040, 51030, 51020 & 51010
ො UDP 5353 (mDNS to broadcast Airplay)
• How to verify Airplay is broadcasting:
1. Ensure that your iOS device and ViewBoard® are connected to the same
subnet network.
2. Open Control Center and touch Airplay Mirroring on an iOS device, e.g.
iPhone/iPad.
3. You should see a device prefixed with "Cast-xxxx".
4. If "Cast-xxxx" is showing then this confirms that the vCastReceiver is
broadcasting Airplay services.
5. Click on the broadcasted "Cast-xxxx" device to mirror your iOS device to
ViewBoard®.

Note:
1. Connect to the same network (Local Area Network), select 5G mode for optimal casting
2. ViewBoard® Cast will stay up to date with the latest version of AirPlay for ongoing compatibility
5
Chromecast Service
ViewBoard® Cast software supports native Chromecast screen sharing via the
Chrome browser casting respectively with the Chromecast feature enabled.
Please ensure that mDNS is enabled on the network/access point/wireless
controller (where applicable).
Network information
• Ports:
ො TCP 8008 & 8009
ො UDP 5353 (mDNS to broadcast CCast)
• How to verify Chromecast is broadcasting:
1. Ensure that your Chromebook and ViewBoard® are connected to the same
subnet network.
2. It is recommended to use Wi-Fi: 802.11n 5GHz.
Note: See 5 GHz channel for a table on non-DFS channels in your country. In
the USA, those channels are 36-48 and 149-165.
3. Bandwidth: At least 2~5 Mbps per user in a typical deployment. Latency
should be less than 100ms when ping Google’s public DNS server at 8.8.8.8
for HD video streaming preferably >5Mbps is required.
4. Access points:
i. For small deployments of under 30 devices, consumer-grade networking
equipment is sufficient.
ii. For deployments greater than 30 devices or involving multiple rooms,
enterprise-grade, centrally managed networking equipment is
recommended.
