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 the
internal jumper under the terminal guard. It is
tted by default.

Overview
railSplit uno is a fully bi-directional DMX512 isolator and signal booster, 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 ‘Fix Mode’ on page 6 for more information.
railSplit uno oers industry leading levels of protection on input, output and power terminals. It
features electrocution protection (self-healing) on the DMX512 ports (up to 425 VAC continuous
connection).
Additionally, railSplit uno provides surge protection on all terminals. This feature protects the
product and connected equipment against voltage surges of the type generated by lightning.
The protection is sacricial which means that after a certain number of protection events, the
protection circuitry will fail (see Specication on page 8). When the protection circuitry fails it
is guaranteed to fail short-circuit, which continues to provide protection to the DMX512 cables.
DMX512 output protection failure or shorted cable is reported with a front panel indicator and
via the fault tally output (see Connections diagram on page 3).

Connections
Input
The DMX512 input is attached via three screw
terminals. Please refer to the Connections
diagram.
Loop-Through
The DMX512 input can also be used as a
passive loop-through connection allowing
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 the internal jumper under the terminal
guard. It is tted by default.
Output
The output is capable of driving 32 additional
DMX512 devices. A terminator must be
connected to the nal DMX512 device.

Application Diagram
The diagram below shows how railSplit uno could be utilised in a typical application.
Internal Earth and Isolation
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.
Circuit Description
DMX512 Input Type: Isolated
Pin 1: Connects to internal isolated
circuit. No connection to
Internal Logic Ground
DMX512 Output Type: PSU referenced
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, the output operates as a bi-directional RDM port and all DMX data received is
passed onto the output. The indicators have the following meaning:
Top (Data):
yOFF = no data received
yGreen = DMX and RDM received
yYellow = DMX only received
Middle (Power):
yGreen = Power
yRed = Data error or collisions detected
Fix Mode
Fix mode is intended to solve product compatibility problems. Unfortunately, there are numerous
products on the market which will not accept the wide range of legal DMX timings and data. Fix
mode cleans 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):
yAs above
Middle (Power):
yGreen = Power
yRed = I am xing something

Protection and Reporting
The DMX512 output surge protection contains a sacricial element that will fail after a certain
number of protection events (see Specication on page 8). When this failure occurs, the output
will short together all 3 terminals.
Output short-circuit is monitored and reported by the product as follows:
Indicator
Tally output
The bottom LED indicator shows the monitoring status as follows:
yOFF = The product is analysing the output or there is no DMX512 input
yGreen = DMX512 output is operating normally
yRed = DMX512 output is short-circuit. This indicates that either there is a short-circuit on
the DMX512 output or that the sacrical protection has failed.
A tally output is provided to allow protection status to be monitored remotely. The tally output is
open-collector allowing multiple products to connect to a single reporting signal.
The output is designed to drive 12 VDC at 5 mA without an additional external resistor.
yTo drive 24 VDC add a 2k2 external resistor.
yTo drive 48 VDC add a 5k6 external resistor.
The output is as follows:
yFloat = The product is analysing the output or there is no DMX512 input or DMX512 output
is operating normally
ySink = DMX512 output is short-circuit. This indicates that either there is a short-circuit on
the DMX512 output or that the sacrical protection has failed.
