c. DMX512 Connection
Connect the provided XLR cable to the female 3-pin XLR output of your controller and the other side to the male 3-
pin XLR input of the VDP575MHS20FL. Multiple VDP575MHS20FLs can be linked through serial linking. The linking
cable should be a two-core screened cable with XLR input and output connectors.
d. DMX512 Chain with Termination
A DMX terminator is recommended for installations where the DMX cable has to run a
long distance or is in an electrically noisy environment (e.g. discos). The terminator
prevents corruption of the digital control signal by electrical noise. The DMX terminator is
simply an XLR plug with a 120Ω resistor between pins 2 and 3, which is then plugged into
the XLR output socket of the last device in the chain.
Please see illustrations.
