This post is valid for the following configurations:
Connecting M-PC to Vision 2.3 PC via Art-net.
Connecting M-PC to Vision 4 MAC via Art-net.
NOTE: Currently Martin has no known method of making M-PC broadcast Art-net locally. This guide assumes a dual computer setup.
Launch M-PC and either start a new show or open an existing file.
After M-PC launches, select M-PC -> Menu from the top left corner.
Select "Network", this will be near the bottom left of your screen.
Select "Interfaces", this will be towards the bottom and has a wifi icon.
Under Settings, select static and change the M-PC's IP address, this will change your computer's IP address as well. Click Apply. (NOTE: According to Martin support, the IP address of the machine with M-PC running MUST BE in the 2.x.x.x format and Subnet Mask MUST BE 255.0.0.0)
Finally, under EtherDMX -> Settings, verify that Artnet is turned on.
Also note that both computers MUST be in the same subnet. I.E. your vision computer must also have an ip address of 2.x.x.x and a subnet mask of 255.0.0.0.
