the lynx equipment controllers, such as the ssr4(dmx), FS, Express, and MR16 should respond to any DMX commands sent from just about any device that sends DMX data. only thing to watch for is if the helix uses a special connector that doesnt line up with the lynx. (in that case an adapter can easily be made)
the pixelnet wount be able to be controlled by the helix
the dongle wont work with the helix (unless the helix can RECEIVE dmx data)
