If I remember correctly, one of the features of the MX was it was able to control AMX lights. The issue may be that the school doesn't have DMX at present, which I have seen. So in essence, they are using the MX as a AMX/DMX convereter.You would need the Midi box from Chamsys to get timecode out of the laptop (I assume you where hoping to remote into the laptop to control the strand?).
You would be better off getting a ChamSys Dongle and just unplugging the strand while focusing. Then you also have a backup desk.
