Midi Keyboard for dumbies

Thanks to anyone that can help..

So running Ion (legacy) XP version latest EOS update. 

I'm wanting to connect a M Audio Oxygen8 midi keyboard as a submaster, effects wing in addition to the existing fader wing..  I know it's old and probably not the best for the task, but it's what we have..

I've looked through the manual, and I'm simply struggling to understand, what to do other the plug in the MIDI lead..

Have only been involving in lighting for 10 months so I'm still pretty green on the more technical side of the software..

Thanks again..
