You can also connect it to a PC and use the LEGACY SYSTEM UTILITY VERSION 2.0 to do the job. The LSU is also very handy for entering data into the command base, you can do it with a full keyboard and not with a knob and buttons.
Here's the LEGACY SYSTEM UTILITY MANUAL v2.0 that shows you how to use it. I have mine connected through my network, so I can maintain the command base from my computer without doing any cabling.
