BenQ InstaShow VS25 / WDC25 Button Kit USB-C / HDMI Transmitter
PRODUCT DESCRIPTION
BenQ InstaShow VS25 / WDC25 Button Kit USB-C / HDMI Transmitter (VS25/WDC25 Button Kit) - Local Warranty
An Add-On Transmitter for the VS25 Host — Not a Standalone Product
This is an additional InstaShow Button for a meeting room that already runs a BenQ InstaShow VS25 Host. It is a transmitter only: there is no receiver in the box, and it cannot send a picture to a display by itself. It pairs with the VS25 Host, and shares the same Button design as the WDC25 generation. It does not pair with a WDC10, WDC10C, VS20 or WDC15 Host — InstaShow Buttons are model-specific. If the room has no Host yet, order the InstaShow VS25 system, which includes a Button and a Host Button.
Plug In, Press, Present — No App, No Driver, No Network
The Button is pure hardware. A presenter plugs it into their laptop's USB Type-C port, or into HDMI with the supplied cable, and presses the front button. Nothing is downloaded, nothing is installed, no account is created and no wireless network is joined, so Windows, macOS, Linux and ChromeOS machines all behave the same. For a security team that means no agent on an unmanaged guest device, and presentation traffic that stays on the direct Button-to-Host link rather than crossing the corporate LAN. The link is protected with AES128 and WPA3-Enterprise.
Swappable Type-C and HDMI Plugs, with a Split Screen Key
The plug on the Button swaps between USB Type-C and HDMI with a Phillips #0 screwdriver, so one room kit serves a mixed laptop estate and facilities can replace a worn plug instead of the whole transmitter. A side Split Screen Key lets the presenter bring their source into a multi-source layout on the room display without touching the Host, which is what makes a VS25 room work for workshops and design reviews where several people contribute in turn. Output matches the Host at up to 4K 60 Hz over HDMI.

Compatibility & Installation
Which Host it works with
The BenQ InstaShow VS25 Host. The same Button design is used across the WDC25 generation. It is not interchangeable with WDC10, WDC10C, VS20 or WDC15 Buttons, and it cannot be used on its own.
Pairing
The Button is paired once to the room's VS25 Host using the pairing procedure in the VS25 user manual. After pairing it behaves exactly like the Button supplied with the system.
What the presenter connects
USB Type-C on the laptop, or HDMI using the supplied Button HDMI cable. No app, driver, account or network join is required. The plug can be swapped between Type-C and HDMI with a Phillips #0 screwdriver.

Frequently Asked Questions — BenQ VS25 / WDC25 Button Kit
Can I use this on its own?
No. This is a transmitter only. It requires a BenQ InstaShow VS25 Host already installed on the room display.
Will it work with my WDC15 or WDC10 Host?
No. InstaShow Buttons are model-specific. This Button pairs with the VS25 Host and uses the same design as the WDC25 generation. For a WDC15 room order the WDC15 Button Kit; for a WDC10 room, the WDC10 Button Kit.
Does the presenter have to install anything?
No. Plug the Button into USB-C or HDMI and press it. No app, driver, account or network join, on any operating system.
Can I change the plug from Type-C to HDMI?
Yes. The plug is swappable using a Phillips #0 screwdriver, so the same Button serves a USB-C laptop or an HDMI one, and a worn plug can be replaced.
How many Buttons can one Host take?
Up to 64 devices can be connected to a VS25 Host.
What does the side key do?
It is a Split Screen Key: it brings the presenter's source into a multi-source layout on the room display without anyone touching the Host.
Does this Button enable the room camera and microphone?
The BYOM function is provided by the VS25 system's Multimedia Hub, which is supplied with the Host. Once paired, this Button works with that setup in the same way as the Button supplied in the box.
What warranty and invoice do I get?
Every unit sold by SourceIT carries a local Singapore warranty and is supplied with a GST invoice.
