Software

To be able to configure the SK621, you must download and install version 1.01 of the Portal software from http://www.coolermaster.com/downloads/. Once you run the Portal software, it will automatically detect all compatible hardware and give you the ability to manage the installation of the application and update the firmware if needed. To install the software for the SK621, you just select it from the list on the left-hand side and click the “Install” button.

Before we started the newly installed software, we also updated the SK621 firmware to make sure it was fully up to date.

Running the software, there are 5 different menu items for configuring the SK621. They include Wireless, LED, Macro, Key Map, and Profiles. On the “Wireless” tab, you can configure certain settings when the SK621 is in wireless mode. These settings include sleep mode, LED brightness, and LED ring. Adjusting these settings should help extend the battery life of your SK621.

  • Rainbow wave – Cycling colors that go across the keyboard

On the Macro tab, you are able to record key actions and then assign that to a single key. For each macro you record, you can set it up either to run once when the key is pressed, run while you’re holding the key down or toggle on/off when you press the key.

The next tab Keymap allows you to re-assign or disable each key on the keyboard. Each key has a colored border letting you know if it has been reassigned (purple) or disabled (red).

The last tab allows you to create and manage each of the 4 profiles of the SK621.
