Ion midi port power output

Question

Is the Ion supposed to output power from the midi port? I'm sending MSC to fire projection cues I believe in D3. not sure though. 
 the video programmer says he's having issues because the ion isn't outputting the standard 5v of power a midi port should output. I have never heard of the ion outputting power over midi so I'm asking on here to see if he is right and whether or not there's something wrong with the console.

The current MIDI Specification (Update 2014) does not regulate a 5v output. With modern electronics, the required 5mA current can be achieve with 3.3v. Some older non-standard MIDI equiment might rely on 5v from a MIDI source. In such a case a self-powered MIDI splitter might help.
