3.4 System Compatibility and Key Definition Software

The MK321BT provides key definition setting software based on the Windows operating system. This software allows you to customize the functions of each of the three keys.

For Windows Users: Install and use the key definition software to program your desired functions.
For Linux or Mac Users: You must first set up the key definitions on a Windows system. Once configured, the settings are stored on the keyboard and will function on your Linux or Mac device without needing the software installed on those systems.
