Download the Braille Terminal Tools application to install the Chameleon 20 driver on versions of Jaws earlier than 2020. If you are running Jaws 2020, ensure it is running the latest update, as the Chameleon 20 driver is included in Jaws 2020. For versions earlier than 2020, simply download and run the Braille Terminal Tools.exe file, and follow the prompts, ensuring that Chameleon 20 is the selected braille display when asked. After installing the driver, you will need to restart Jaws.
