Cooler Master Portal Software
Once the Cooler Master Portal software is downloaded, installed, then told to run, what we have shown is what you should see initially. The first tab of the software for the SK621 deals with the Bluetooth power-saving settings. The first is a timer for the sleep mode and can be set anywhere from five minutes of inactivity to no timer at all. The LED brightness can be adjusted, lower saving more battery, and along the same lines, you can also turn off the side LED ring.
If you want to change the color or the mode of the lighting, you will need to hit the LED tab at the top of the Portal window. It is here you can choose one of the many modes, with all of the favorites included, or you can pick static colors as well. In the single LED options, you can choose the color with the color picker at the top, or via RGB values. There is also a bar for speed, but that is reserved for modes with action.
Under the Macro heading is where you can open the editor. On the left is where you would name the Macro, as we have to open the rest of the editor. In the middle, at the bottom, is the record button, and once pressed, any commands typed will show in the center window. Once done, you can choose how to deploy the Macro, but editing options after the fact are limited. The section on the right is where you can easily assign a button to any Macro, and with any settings changes, be sure to apply progress to the profile, which can be selected at the top-right of the main window.
The keymap section is what you would assume it to be; the place you would go to remap any of the keyboard, except for the @/2/F2 key, but anything else can be remapped. You can also use this section to enable and disable keys, but as far as we can tell, you can only remap keyboard functionality, not other device functions like a mouse click.
While we mentioned that one could program profiles by using the dropdown box at the top, the profiles section is where you can manage them. 512KB is a lot of memory for a peripheral, but even so, only four profiles can be stored at one time. To lessen the limitation, Cooler Master offers this, so that you can import and export profiles to the storage on the device the software is running on, and swap them out as required for use.
