Vario 340
The compact uncomplicated Braille display - just plug in and go.
The Vario 340 is a high quality yet affordable 40-cell braille display for computer users in need of a compact, lightweight solution for use with computers at home, work, or school. Like other BAUM braille displays, Vario 340 is a Human Interface Device (HID), which means a driver does not need to be installed to use it. Vario 340 features a reversible USB Type C port, which means it doesn’t matter which direction the USB plug is facing.
Vario 340 has everything you need for quick access to information. Plus, it’s easy and comfortable to use.
Upgrade: HID-Braille for your Vario 340
Plug in a braille display and get started right away, with no drivers and no setup: that is exactly what HID Braille stands for, because this new connection standard makes true plug and play possible for braille displays. Developing our new firmware with full HID Braille support was therefore a real milestone, and a step like that deserves a fitting product name and a modern look: so the milestone became a new product, the VarioHID 40.
And we decided not to reserve this progress for new devices alone. We beliebe a good braille display should accompany its user for many years, and over those years it should keep getting better. That is why every Vario 340 receives the same firmware.
Completely free of charge, with no need to send the device in, and easy to install yourself.

You only need this JAWS extension if you want or need to use JAWS with the VarioClassic protocol used in the past.

The ZIP file contains detailed installation instructions for the extension.
JAWS and NVDA key assignments for the VarioHID protocol
22 September 2026 (ZIP | 610 KB)
JAWS/Fusion up to version 2026 and NVDA do not yet include key assignments, which means that Vario braille displays can connect to the screen reader but cannot be used effectively.
We are therefore making preconfigured key assignments available for download here. Future versions of JAWS will already include these key assignments from the manufacturer (Vispero).
