Rail-Split DMX User Guide
Overview
Rail-Split DMX is a uni-directional DMX512 splitter and distribution amplifier. By design, Rail-Split
DMX does not support RDM, allowing a cost-saving to be passed on to those customers who
do not require bi-directionality. Customers requiring RDM functionality should order the sister
product, Rail-Split RDM, as opposed to Rail-Split DMX.

Connections
Input
The DMX512 input is attached via three screw
terminals. Please refer to the connections
diagram.
Loop-through
A passive loop-through connection allows
onward connection to other DMX512 devices.
If this feature is not required then the signal
must be terminated. The product contains an
internal termination resistor. This is enabled by
fitting a wire link between the screw terminals
that will terminate the DMX line (Term and
DAT+).
Output
Six DMX512 outputs are provided. Each output
is capable of driving 32 additional DMX512
devices. It is not necessary to terminate any
outputs that are not connected. However, a
terminator must be connected to the final
DMX512 device.
