A blue Neutrik PowerCon socket is provided to connect the fixture to AC
mains power.

See 'Safety information' on page 4. The light-grey Neutrik PowerCon socket
can be used to supply power to other fixtures only if the supplied power input
cable is replaced as directed in this manual and safety limits are respected.

Control data link

A DMX 512 data link is required in order to control the fixture via DMX. The
fixture has 5-pin XLR connectors for DMX data input and output.
The number of daisy-chained fixtures is limited by the number of DMX
channels required by the fixtures in relation to the maximum 512 channels
available in one DMX universe. Note that if independent control of a fixture is
required, it must have its own DMX channels. Fixtures that are required to
behave identically can share the same DMX address and channels. To add
more fixtures or groups of fixtures when the above limit is reached, add a
DMX universe and another daisy-chained link.

Tips for reliable data transmission

Use shielded twisted-pair cable designed for RS-485 devices: standard
microphone cable cannot transmit control data reliably over long runs. 24
AWG cable is suitable for runs up to 300 meters (1000 ft.). Heavier gauge
