Once you have all of your light fittings connected to your DMX drivers/decoders, you need to assign addresses to the units from the 512 channels available to you. Each individual zone of control in your lighting system will require its own unique address.
All of this is done using dip switches which are normally located near the DMX input and output sockets.
Generally, there will be 10 dip switches on the device and these are used for setting a binary address. Each of the switches has a corresponding value and the DMX address is calculated by adding together these values. Below is a chart which shows that switch one is worth ‘1’, switch two is worth ‘2’, switch three is worth ‘4’ and so on. The value doubles each time to a value of 256 for the ninth switch.
