6.1 Connection
1. In order to reduce signal errors and avoid signal attenuation and interference during
transmission, a 90-120Ω (0.25W) resistor can be added between the 2-core and 3-core of the
DMX output of the last machine.
2. Connect the fixture with XLR signal cable, one end is connected to the output port of the fixture, and the
otherendis connectedto the input port ofthenext fixture. XLR signal lines canonly be usedin series, not
in parallel. DMX512 signal transmission speed is very fast. Damaged signal wires, weak soldering, poor
contact,etc.,willaffectsignaltransmissionandcausethesystemtoshutdown
3. When the machine power supply of a unit is disconnected, the connection of DMX output
and input is bypassed in order to maintain the connection of the DMX line.
4. Each lamp must have an address code, which can receive the information sent by the console, and the
range is 0-511 (usually 0&1 and 1 are the same).
。
5. The terminal of the DMX512 system needs to be equipped with a terminal to reduce errors in signal
transmission.
6. 3-pin XLR connector:
3 core XLR: PIN 1: GND, PIN 2: negative signal, PIN 3: positive signal.
