The nice thing is, you want more nodes attached, the power supply will power about 10 of these 5 unit strings so all you have to do is order the three items above listed under ----LIGHTS---- and attach them and they'll light up no problem. Each time you want another light strand you're out $16.42
------------------------------------------------------------------------------
Instructions for POWER:
Cut one end of the single cat 5 line off. Strip the pairs down and separate them. You'll want about 2 inches of shielded wire, and about 1/4th inch unshielded showing.
Take the orange pair and snip them off, they aren't used for power.
Group all 3 of the the solid colored wires together and twist the bare ends tightly.
Put a single sleeve of heat-shrink around all 3 solid colored wires and slide it past where you will be Soldering.
Solder them to the black end of the power supply's bare wire, then after letting cool, move the heat shrink over the connection and heat with a heat gun.
Do the same process now with the three striped wires on the red side.
You may want to electrical tape the entire connection to be sure it stays safe.
----------------------------------------------------------------------------------------
Instructions for the light "node"
You should have a 5 block strand of square LED blocks. You will be adhering them to the sides and top of the Ethernet DMX controller.
The lights come with adhesive on their bottoms so peel off the protective label
Starting in the middle on the top, and work your way on one side, then over to the other all 5 should fit fairly evenly like a rectangle with feet. See photo for reference.
Solder the connections to the 4 wires coming out of the back of the DMX controller, all the colors match except white goes to yellow.
If your light strand had the 4 colored wires coming off BOTH sides, pick which ever is easier to work with the soldering, and snip the others away on the other side.
Each unit isn't all that big, but they put out a lot of light and you can have about 10 of them so each station could have their own if you wanted.
---------------------------USE---------------------------------
You should now be able to pug everything into the 3 way splitter, and the USB connection into your computer. If the drivers auto-load Artemis will simply start using your lights when it's running.
