Screw connector in parallel with RJ45-for-DMX
For the convenience of the contractor, each physical DMX input has two types of connector
in parallel: a pluggable screw terminal block, and a RJ45.
Use one, never use both.
The RJ45 are very convenient to use off-the-shelf STP cables for daisy-chaining between
dimmer cabinets, and connection to RJ45 DMX patchfields.
6.6.2 Pin numbering
For standard DMX cables (2 pairs + screen), the connectors X1 through X8 are connected as
follows:
1
COM 0 Volt conductor (different from the screen)
2 DMX- data 1- (DMX)
3 DMX+ data 1+ (DMX)
4 AUX- data 2- (second data pair)
5 AUX+ data 2+ (second data pair)
6 PE screen in the DMX cable and connection to PE.
(For optimum EMC (Electro-Magnetic Compatibility) performance we recommend to separate
0V from PE)
All screens in all cables should be interconnected.
One end only should be connected to PE, to prevent an earth loop.
Pin configuration of the RJ45-for-DMX:
-
pin 2 = data 1- (DMX)
-
pin 1 = data 1+ (DMX)
-
pin 6 = data 2-
-
pin 3 = data 2+
-
pin 7 and 8 = common 0V
6.6.3 DIP switches SW1
– termination of the DMX data lines
On PCB3031, SW1 switches 1 through 4 allow termination of the cabinets four DMX inputs.
To terminate CPU1-DMXA: set Switch 4 to ON.
To terminate CPU1-DMXB: set Switch 3 to ON.
To terminate CPU2-DMXA: set Switch 2 to ON.
To terminate CPU2-DMXB: set Switch 1 to ON.
DIP switches instead of link cables
On PCB3031, SW1 switches 5 and 6 connect “DMX1A Through” with “DMX2A In”.
Similarly, SW1 switches 7 and 8 connect “DMX1B Through” with “DMX2B In”.
This is a convenient and reliable alternative for short jumper cables.
