Setting up multiple Lil' G 40W Moving Head fixtures for a dynamic light show requires careful connections and configurations. Here's a step-by-step guide:
-
Data/DMX Cabling: You'll need data cables specifically designed for DMX to ensure a stable signal. Choose data-grade cables to minimize electromagnetic interference. The cables should have:
- 2-conductor twisted pair with shielding.
- Maximum capacitance between conductors: 30 pF/ft.
- Maximum capacitance between conductor and shield: 55 pF/ft.
- Maximum resistance of 20 ohms / 1000 ft.
- Nominal impedance 100 – 140 ohms.
-
Fixture Linking (DMX Mode):
- Daisy chain the fixtures by connecting the DMX output of one fixture to the DMX input of the next in a single line.
- Ensure each Lil' G 40W Moving Head has a unique starting DMX address. This allows for individual control of each light.
- Always use a DMX terminator at the end of your chain to maintain signal integrity.
-
DMX Terminator: A DMX terminator is crucial for reliable performance. To create one, use a 120-ohm, 1/4-watt resistor. Wire it between pins 2 and 3 of the DMX output connector on the last fixture in your chain. Avoid any contact between the common and the fixture’s chassis ground to prevent issues.
-
3-Pin to 5-Pin Conversion: If your DMX controller uses a 5-pin output, you'll need a 5-pin to 3-pin adapter to connect to the Lil' G 40W Moving Heads. Ensure you follow the correct conductor mapping to avoid signal errors. (Consult the adapter's documentation for pinout details).
-
Connecting the Fixtures: Use the DMX cables to link the fixtures. Connect the male 3-pin connector of the DMX cable to the output (female 3-pin) of the first Lil' G 40W Moving Head. Then, connect the female 3-pin end of that cable to the input (male 3-pin) of the next fixture. Repeat this process for all your fixtures, remembering to terminate the final fixture with a DMX terminator. By following these steps, you'll successfully link your Lil' G 40W Moving Heads and create an impressive synchronized light show.
