Introduction

vCast Pro software is designed for wireless presentations and collaboration.

Working with vCast Pro software and the vCastSender application allows you to stream live recordings, annotate, and share your screen, photos, videos, annotations, documents, and camera directly onto ViewSonic® ViewBoard® Interactive Flat Panels and other mobile devices. In addition, both advanced display group and moderator management functions are included.

Presenters can control displayed content from a phone, tablet, or laptop while Android and iOS device users are able to use vCastSender’s specialized annotation toolbar and control the ViewBoard® remotely. vCastSender's specialized moderation feature allows a moderator to take control of meetings or classrooms as well.

The Display Group maximum device limit is six devices.

If you frequently connect to the same device, you can select the Star icon () next to the device to add it to your frequently connected devices list, "My List of Devices in Group", for easier Display Group setup and management.

Synchronized Group Screen All the Time

When the “Synchronized group screen all the time” function is toggled ON, it will display a synchronized group screen continuously. If it is toggled OFF, it will work on vCast mirroring only.

NOTE: Select the devices to group first, then toggle the "Synchronized group screen all the time” function ON to avoid interruption.

Share a Screen to the Display Group (One to Many Casting)

After confirming the above settings, you can share your screen to the main display, then the grouped client devices will be synced up to your screen.

Moderator Mode

Moderator Mode allows the moderator to take control of the devices connected to the ViewBoard or display. To enter Moderator Mode, select the Moderator Mode icon () located in the lower-right corner of the screen.

When enabled, the moderator can view a list of all connected screens in the left floating window and can preview each participant’s screen and then select any of participant’s screen and cast to the ViewBoard’s or display's main screen for presentation. The moderator can also control each participant’s screen, annotate on the ViewBoard or display, and remove unwanted participants by selecting the close icon (X).

Moderator Mode is supported on all vCastSender and AirPlay devices, but mobile devices are limited to a "preview" function. Additionally, mobile Android devices cannot cast sound out.
When you cast your Windows/Mac/Chrome screen to a ViewBoard or display, the selected full screen unit will not be broadcasted back to your device to avoid repetitive screen casting.
The active presenter can touch each of the participant's screens to remotely control casting devices.
The number of multi-screen presenters on-screen depends on your Windows CPU processor performance and router specifications.

Casting to vCast Pro from a Client Device

Working with ViewBoard® Cast software (vCast, vCast Pro, and vCastSender), the vCast Pro application will allow the ViewBoard or display to receive laptop screens (Windows/Mac/Chrome) and mobile (iOS/Android) users’ screens, photos, videos, annotations, and camera(s) that are using the vCastSender application.

NOTE:

ViewBoard® Cast software, laptops, and mobile devices can connect to both the same subnet and cross subnet by entering the on-screen PIN code.
Connected devices will show up under Device List on the same subnet connection.
If the device does not show up under Device List, users will need to key-in the on-screen PIN code.
vCast Pro can setup “PIN disable” for a faster connection on the same subnet. Please note that the Remote Viewing function will be enabled if PIN code input is disabled.

Frequently Asked Questions

Question	Answer
What is the minimum Wi-Fi signal strength for a reliable vCast Pro network?	In order to have reliable network signal strength to experience vCast Pro optimally, we suggest the minimum Wi-Fi signal strength for a reliable packet delivery to not be lower than -60 dBm.
What is the minimum video streaming network bandwidth recommended for reliable vCast Pro casting?	Minimum bandwidth recommendation: 1 MB/s (static picture < 100 KB/s; peak value of a dynamic picture is about 1 MB/s). NOTE: Network Latency 1~30 ms: Very Fast; smooth screen casting. 31~50 ms: Good; can screen cast normally, no obvious delay. 51~100 ms: Normal; slight latency may occur when video/pictures are streaming. ≥ 100 ms: Poor; there may be freezing and droppage.
Will multiple screen casting cause latency issues, especially with video streaming content sharing?	Multiple screen casting via video streaming can be a heavy load on a network. To experience ViewBoard Cast with multiple screen sharing with a reliable signal, we suggest the minimum Wi-Fi signal strength is not lower than -60 dBm and the minimum bandwidth recommendation is 1 MB/s. If there is still a latency issue, please reduce vCastSender to not exceed two devices for the best performance.

Troubleshooting

This section describes some common problems that you may experience when using vCast Pro. Additionally, you can contact your sales representative or IT department if you are experiencing any problems.

Problem or Issue	Possible Solution
Device List is not displayed	Please make sure you have followed all instructions for connecting to the same network environment. For more information, see Before Launching vCast Pro.
Unable to connect to vCast Download page	Ensure that the firewall for your operating system permits vCast Pro to run and communicate on your network. This message will only appear if the server is using a self-signed certificate with an invalid trust chain.
