VIA Software for Customization

The ZUOYA GMK26 supports key layout modification using VIA software.

Note: Ensure your numpad is correctly plugged into your computer when using VIA.

VIA Installation Steps:

Visit https://github.com/WestBerryVIA/via-releases/releases to download and install the latest VIA software for your operating system.
Download the 'ZUOYA GMK87-USB.JSON' (for wired mode) or 'ZUOYA GMK87-2.4G.JSON' (for 2.4GHz mode) file from the distributor's website. Open VIA software, select 'File', then 'Import Keymap', and choose the corresponding JSON file.
A successful connection is indicated by the VIA software recognizing your keyboard. If VIA cannot recognize your numpad, please contact customer support.

VIA automatically detects compatible keyboards. Keyboard memory is persistent, meaning settings are remembered regardless of where the keyboard is plugged in.

Key Remapping:

In the upper half of the VIA software page, click to select the key you want to change. Then, in the lower half, click the desired new function for that key.

Layers:

The GMK26 has 4 default layers (0-3), allowing each key to have multiple functions. This is useful for smaller keyboards.

Layer 0: Activated when connected to Windows.
Layer 1: Activated when connected to Mac. (Note: Left Alt, Left Option, Left Win, Left Command, Right Alt, Right Option are mapped for Mac compatibility).
Layer 2: Activated when connected to Win/Mac. Remap any key to MO(2) in VIA. Hold MO(2) to activate Layer 2.
Layer 3: Activated when connected to Win/Mac. Remap any key to MO(3) in VIA. Hold MO(3) to activate Layer 3.

Special Keys Setting:

Troubleshooting

VIA Software Not Recognizing Numpad: Ensure the numpad is connected via USB-C cable (wired mode) and the correct JSON file is loaded in VIA. If issues persist, try a different USB port or cable, or contact customer support.
