Power supply

To determine the power requirements for a particular fixture, see the label
affixed to the back plate of the fixture or refer to the fixture's specifications
chart. A fixture's listed current rating is its average current draw under
normal conditions. All fixtures must be powered directly off a switched
circuit and cannot be run off a rheostat (variable resistor) or dimmer circuit,
even if the rheostat or dimmer channel is used solely for a 0% to 100%
switch. Before applying power to a fixture, check that the source voltage
matches the fixture's requirement.

DMX-512 connection between fixtures

The fixture is equipped with 3-pin XLR sockets for DMX input and output.
The sockets are wired in parallel. Only use a shielded twisted-pair cable
designed for 3-pin XLR-plugs and connectors in order to connect the
controller with the fixture or one fixture with another.

Occupation of the XLR-connection

Caution! At the last fixture please use a DMX terminator. That is
a XLR plug with a 110 ohm resistor between pins 2 and 3. Plug
that terminator into the DMX output of the last fixture.

Building a serial DMX chain

If you are using standard DMX-controllers, you can connect the DMX-
X
output of the controller directly to the DMX input of the first fixture in the
