When using on PS5, you will need either the PS5 version of the device or a PS5 authentication device connected to the EX port.
Once these conditions are met, set the Input Mode to PS5 to enable use on PS5. (For the PS5 version, the Input Mode is preset to PS5 at shipment, so no adjustment is required.)

With TIKITAKA’s default firmware, PS5 settings are already configured.
However, if the device has been reset or settings have been changed, please set both “Input Mode Setting” and “Peripheral Mapping” as shown in the images below. This configuration also works for PS4.
