** 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 tting a
wire link between Term and DAT+.

Rail-Split RDM User Guide
Overview
Rail-Split RDM is a fully bi-directional DMX512 splitter and distribution amplier, with the added
feature of a ‘data xer’ for DMX. The latter functionality is used for resolving ickering problems
arising from product incompatibility issues - see ‘Fixer Mode’ on page 6 for more information.

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
tting 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 nal
DMX512 device.

Application Diagram
The diagram below shows how Rail-Split RDM could be utilised in a typical application.
The following table summarises the internal earth interconnection and isolation.
Please note that we use the term Earth-Ground to avoid international confusion. In Europe
Earth-Ground is called Earth; in the USA, Earth-Ground is called Ground.

Pin 1: Connected to Internal Logic
Ground
Internal Logic Ground Connected to power supply 0V. If the selected PSU has a connection
between Earth-Ground and 0V the DMX outputs become Ground
Referenced. Otherwise the DMX outputs are Floating. When the
recommended PSU is used, DMX outputs are Floating.

Operating Modes
The product can operate in two modes. In its default mode, the product is a fully-featured RDM
Splitter. In the second mode, it acts as a DMX Fixer.
Splitter Mode
In splitter mode, all six outputs operate as bi-directional RDM ports and all DMX data received
is passed onto the outputs. The indicators have the following meaning:
Top (Data):
OFF = no data received
Green = DMX and RDM received
Yellow = DMX only received
Bottom (Power):
Green = Power
Red = Data error or collisions detected
Fixer Mode
Fixer mode is intended to solve product compatibility problems. Unfor tunately, there are numerous
products on the market which will not accept the wide range of legal DMX timings and data.
Fixer mode attempts to clean-out any unusual or non-standard timing and data before sending
to the output. This includes stripping out all non-zero start codes (including RDM), forcing a
512-channel footprint and calming any timing jitter. Indicators have the following meaning:
Top (Data):
As above
Bottom (Power):
Green = Power
Red = I am xing something
