Notes
It is essential that each fixture is correctly grounded and the electrical installation conforms to all relevant Standards / Codes
of Practice for Safe Electrical Work.
Control connection
The fixture has 5-pin (3-pin optional) XLR connectors for DMX data input and output as shown below. Connection between
the console and fixture, and between fixtures must be made with 2 core screened DMX signal cable. Maximum connecting
distance of signal cable is 150 meters. Additional DMX512 signal-amplifier is recommended for longer distance.
Connect the Console’s DMX OUTPUT to the first fixture’s DMX INPUT, then the first fixture’s DMX OUTPUT to the second
fixture’s DMX INPUT and so on. It is recommended not to connect more than 32 units on a single DMX universe. On the last
fixture‘s output connect a DMX terminator. (The terminator is a XLR connector with a ¼ W and 120Ω resistor between the
pin 2 and pin 3) as shown below:
Testing
Connect the fixture to AC power. Check if the LED lamp is on and the fixture is independently controllable before putting
into operation.
