ViewBoard Network Requirements

Introduction

This document outlines the network requirements for ViewBoard's pre-loaded software, assisting IT administrators in setting up ViewBoard products within their IT infrastructure.

Note:

• Ensure the wireless infrastructure supports broadcast services and is enabled.
• For optimal transmission stability, it is strongly recommended to connect the ViewBoard via an Ethernet cable and ensure client devices utilize a 5 GHz Wi-Fi band.

Over-the-Air (OTA) Service

A ViewBoard automatically searches for firmware updates when connected to the Internet.

Network Information:

• Server FQDN Name: ifp-ota.s3-accelerate.amazonaws.com, www.viewsonicglobal.com
• Server Port: TCP 443

Air Class

Air Class enables displaying quiz questions on a ViewBoard and allows up to 30 mobile users to submit answers remotely. It records the results from each device used.

Network Information:

• All devices, including PCs (Windows/Mac/Chromebook), tablets/mobiles (iOS/Android), and the ViewBoard, must be connected to the same LAN network subnet.
• Port: TCP 8080

vCastReceiver & vCastSender Service

The vCastReceiver app, working with ViewBoard Cast software, allows the ViewBoard to receive content from vCastSender, including laptop screens (Windows/Mac/Chrome) and mobile (iOS/Android) device screens, photos, videos, annotations, and camera feeds.

Network Information:

• ViewBoard Cast software, laptops, and mobile devices can connect to both the same subnet and across subnet networks.
• Connection requires entering the on-screen PIN-code on the client device.

vCastReceiver Network Details

Ports:

• TCP 56789, 25123, 8121 & 8000 (Controlling message port & client device audio transfer)
• TCP 8600 (BYOM)
• TCP53000 (Request share screen)
• TCP52020 (Reverse control)
• TCP52025 (Reverse control for ViewBoard Cast Button)
• TCP52030 (Status sync)
• UDP 48689, 25123 (Device searching and broadcast & client device audio transfer)
• UDP 5353 (Multicast search device protocol)

Port and DNS for Activation:

• Port: 443
• DNS: https://vcastactivate.viewsonic.com

OTA Service:

• Server Port: TCP 443
• Server FQDN Name: https://vcastupdate.viewsonic.com

AirPlay Service

Note: Ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).

Network Information:

• Ports:
  • TCP 51040, 51030, 51020 & 51010
  • UDP 5353 (mDNS to broadcast Airplay)
  • UDP random port with a range of 52000~53000 (Transfer audio; assigned by AirPlay protocol)
• How to verify AirPlay is broadcasting:
  1. Ensure your iOS device and the ViewBoard are connected to the same subnet network.
  2. Open the Control Center and select 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 displayed, it confirms that the vCastReceiver is broadcasting AirPlay services.
  5. Click on the broadcasted "Cast-xxxx" device to mirror your iOS device to the ViewBoard.

Chromecast Service

ViewBoard Cast software supports native Chromecast screen sharing via the Chrome browser, provided the Chromecast feature is enabled.

Note: Ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).

Network Information:

• Ports:
  • TCP 8008 & 8009
  • UDP 5353 (mDNS to broadcast CCast)
• How to verify Chromecast is broadcasting:
  1. Ensure your Chromebook and ViewBoard are connected to the same subnet network.
  2. It is recommended to use Wi-Fi: 802.11n 5GHz. (Refer to 5 GHz channel guides for country-specific non-DFS channels, e.g., 36-48 and 149-165 in the USA).
  3. Bandwidth: At least 2~5 Mbps per user is required for typical deployments. Latency should be less than 100ms when pinging Google's public DNS server (8.8.8.8). For HD video streaming, more than 5 Mbps is required.
  4. Access points:
     • For deployments 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.

Display Service

myViewBoard Display allows users to wirelessly mirror their desktop to supported Interactive Flat Panels (IFP) and Wireless Presentation Displays (WPD). It comes pre-installed on select ViewBoard hardware but can also be installed manually on any IFP or WPD running Android 6 or higher. Once installed, users can mirror their device screen to the host using a compatible browser.

Network Information:

• Ports:
  • TCP Port 443 (HTTPS): outbound
  • UDP and TCP port 3478 bidirectional to the WebRTC servers
  • UDP Ports 50,000 – 65,535 (RTP/sRTP/RTCP) bidirectional to the WebRTC servers. These ports are optional; if blocked, media will be proxied using TURN on port 3478.

Manager Service

myViewBoard Manager is a tool for Entity Administrators to remotely manage multiple installations of ViewSonic visual solution devices, such as a ViewBoard. To access, select the Entity Management tile, then navigate to Devices on the side panel.

Note: This feature is exclusively available for users logged in with an Entity Administrator account. For more information, visit: https://wiki.myviewboard.com/MyViewBoard_Manager.

Network Information:

• Ports:
  • TCP Port 443 (HTTPS): bidirectional
• Whitelist the URL: myviewboard.com

Miracast Service

Miracast facilitates wireless streaming of content from Windows and Android devices to an Interactive Flat Panel (IFP) or Wireless Presentation Display (WPD).

Note: Ensure that mDNS is enabled on the network/access point/wireless controller (if applicable).

Network Information:

• Ports:
  • TCP Port 7236: Wi-Fi direct control port used to establish and manage sessions between the source device and ViewBoard.
  • UDP port 21200 for RTP packets and UDP port 21201 for RTCP packets.
  • UDP 5353 for multicast DNS (mDNS) broadcast to the local subnet.
• IP address(s): IPv4 address: 192.168.49.0, subnet mask: 255.255.255.0.
