Note: Care should be taken to ensure that none of the pins touch the metallic body of the plug or each other. The body of the plug is not
connected in any way. The device accepts digital control signals in protocol DMX512 (1990).
Maximum 32 units can be connected in series by 3-pin signal cable. Connect the controller’s output to the first fixture’s input, and
connect the first fixture’s output to the second fixture’s input and connect the rest fixtures in the same way. Eventually connect the last
fixture’s output to a DMX terminator as shown in the figure below.
Note: For synchronous control, Start Addresses for all slave units must be same.
Each unit’s POWER INPUT should be connected to external POWER individually and the voltage and frequency of the power
supplied match what its nameplate describes.
.
DMX TERMINATOR
In the Controller mode, at the last fixture in the chain, the DMX output has to be connected with a DMX terminator. This prevents
electrical noise from disturbing and corrupting the DMX control signals.
The DMX terminator is simply an XLR connector with a 120
Ω
(ohm) resistor connected across pins 2 and 3, which is then plugged
into the output socket on the last projector in the chain. The connections are illustrated below.
