HHKB Pro2 Connectivity & Settings

Current output of the Integrated USB HUB

The 2x USB downstream ports (USB HUB) on the back side supply a current of 100 mA on each port.
Before connecting a USB device to the ports, check that the consumption current of your USB device does not exceed 100 mA or the USB device may not be detected and may not function correctly.

HHKB Pro2 Dip-Switch Settings

By using the Dip-Switches on the back of the keyboard, you can change the Keyboard Mode and functions of some of the keys on the Keyboard. The HHKB mode is set as the factory default.

Important! Please disconnect the HHKB from the host PC before changing the Dip Switch settings or changes may not be recognised and you may damage the product.

To change Dip Switch settings, we recommend using a small screwdriver that is approximately 1.2mm in diameter.

Key Assignment & Enabling Wake-Up Host PC Feature

² The Left Meta key functions as:

• Windows key under Microsoft Windows

³ When Wake-Up Host PC feature is enabled:

• The keyboard consumes power even if the computer is in a suspended state.
• You may need to change the Profile or settings in the Power Management settings of the host PC’s Operating System.
• This feature may not work on all systems.

Select the same height setting on the Left and Right sides of the keyboard, ensuring the feet click correctly into position.

Keyboard Layouts & Settings

Microsoft Windows

To use the HHKB in Windows, go to ‘Regional Settings’, ‘Keyboards & Languages’ tab, click the ‘Change Keyboards’ button and ensure you have the following keyboard installed:

English (United Kingdom): ‘Keyboard – United Kingdom’
French (France): ‘Keyboard – French’
German (Germany): ‘Keyboard – German’
Italian (Italy):  ‘Keyboard – Italian’
Spanish (Spain): ‘Keyboard – Spain’

You can use the ‘Add’ button to add the required Keyboard if it is not already installed in Windows.

Japanese Keyboard Settings

If you use the HHKB with the Japanese keyboard setting, you cannot input symbols such as brackets and @ in accordance with the symbols on the keys.

When you connect the keyboard to a laptop computer with a Japanese keyboard and change the keyboard layout setting to the English keyboard, you cannot input symbols in accordance with the symbols on the keys of the laptop computer. This is caused by a feature of the operating system.

Apple macOS

After the dedicated driver for macOS is installed, the [Alt] key works as the [Option] key and the [0] key works as the [Command] key.

To use multimedia keys, press the [Fn] key and one of the following keys at the same time.

Available on macOS only.
