MG3 Installation Instructions

Jo’s 5 minute installation video covers the basics of hardware, software, and testing, so start with that.

The diagram below elaborates on the video instructions, spelling out the connection differences between K40’s with and without ribbon cables.

MG3 connections for K40’s with and without ribbon connectors

If you have the K40 power supply type below (which wasn’t shown in the video) then please refer to the MG2 installation page which is similar to MG3 and should provide enough guidance.

The only other thing not spelled out in the installation video is that you’ll need a mini B USB cable.
