Try it with the default channel of 1....

To expand on Doctor Keith's reply
All lynx dmx hardware default to channel 1
So using your DMX light controller
Use a XLR to RJ-45 cable (see wiki if you need to make one)
Plug in the SSR4-dmx and add lights to one or all four channels
Add power and more the sliders up or down and see if the lights work
