Getting data from your desk to your fixtures is all about proper networking. Whether you're using Art-Net, sACN, or direct DMX ports, understanding how GrandMA3 routes and sends signal is key to a stable, responsive lighting system. The software gives you fine control over every layer—from IP addresses to DMX universe assignments—so you can tailor your setup to any size rig.

Connector Configuration

Start in the Connector Configuration menu to set how the ports on your console or node behave:

• Out Port / In Port / Disabled: Assign port function based on your signal flow.

• Choose DMX universe assignments per port.

• Configure SMPTE and MIDI timecode slots if you're using external sync.

With the right converters, any port can be reassigned as input or output.

Session Management and Network Devices

In the Network menu, you can:

• View all MA devices on your network.

• Invite onPC stations or consoles into your session.

• Promote your desk to Global Master to control output across devices.

Pay attention to your session status: you must be set as Idle Master or Global Master to output DMX protocols like Art-Net or sACN.

MAnet Interface and IP Settings

Select which network adapter your MA-Net runs through—important when using multiple Ethernet ports on a console or PC. Console users can set IP and subnet directly; onPC users must set these from the Windows side.

Sending sACN and Art-Net

In the DMX Protocols menu:

• Set the correct Ethernet interface for output.

• Enable output and verify your Send if Idle Master setting is on.

• Choose Multicast or Unicast depending on your network.

For Art-Net, MA automatically calculates net, subnet, and universe based on the absolute value you enter, simplifying setup across complex networks.

Use the live signal indicators (flashing green or yellow) to confirm data is flowing correctly—an easy way to validate your output without extra tools.
