2 Safety instructions
This device is intended to be used for the distribution of DMX signals from one to multiple
DMX chains, or to extend a DMX chain. Use the device only as described in this user manual.
Any other use or use under other operating conditions is considered to be improper and may
result in personal injury or property damage. No liability will be assumed for damages resulting
from improper use.

DANGER!
Danger for children
Ensure that plastic bags, packaging, etc. are disposed of properly and are not
within reach of babies and young children. Choking hazard!
Ensure that children do not detach any small parts (e.g. knobs or the like) from
the unit. They could swallow the pieces and choke!
Never let children unattended use electrical devices.
DANGER!
Electric shock caused by high voltages inside
Within the device there are areas where high voltages may be present. Never
remove any covers.
There are no user-serviceable parts inside.

DANGER!
Electric shock caused by short-circuit
Do not modify the mains cable or the plug. Failure to do so could result in electric
shock/death or fire. If in doubt, seek advice from a registered electrician.
NOTICE!
Risk of fire
Do not cover the device nor any ventilation slots. Do not place the device near
any direct heat source. Keep the device away from naked flames.
NOTICE!
Operating conditions
This device has been designed for indoor use only. To prevent damage, never
expose the device to any liquid or moisture. Avoid direct sunlight, heavy dirt, and
strong vibrations.

NOTICE!
Power supply
Before connecting the device, ensure that the input voltage (AC outlet) matches
the voltage rating of the device and that the AC outlet is protected by a residual
current circuit breaker. Failure to do so could result in damage to the device and
possibly injure the user.
Unplug the device before electrical storms occur and when it is unused for long
periods of time to reduce the risk of electric shock or fire.

4 Installation
Unpack and check carefully there is no transportation damage before using the unit. Keep the
equipment packaging. To fully protect the device against vibration, dust and moisture during
transportation or storage use the original packaging or your own packaging material suitable
for transport or storage, respectively.
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
The unit has been designed for rack mounting in a standard 19-inch rack; it occupies one rack
unit.

Three- and five-pin XLR sockets serve as DMX outputs, a three- or five-pin XLR plug is (option‐
ally) used as DMX input. The drawing below and the table show the pin assignment.

5 Starting up
Establish all connections as long as the unit is switched off. Use the shortest possible high-
quality cables for all connections.
NOTICE!
Possible interference in data transmission
To ensure smooth operation use special DMX cable instead of normal micro‐
phone cable.
Never connect DMX outputs to any audio equipment such as mixers or amplifiers.

The figure below shows schematically how to integrate the unit into a DMX configuration.
Connect the device (S) as the last part of the DMX chain, which starts with your DMX controller
(C). To do so, connect the DMX input of the device to the DMX output of the second last DMX
device in this DMX chain.
Each of the unit's DMX outputs 1to 4allow connection of one DMX chain, which in turn may
consist of a maximum of 32 DMX devices. Connect the output of the first DMX device to the
DMX input of the second and so on, to form a series circuit. Make sure that the output of the
last DMX device in the chain is terminated by a resistor (110 Ω, ¼W). You can further expand
the configuration of your DMX network by using additional DMX splitters at the end of the
DMX chains. Keep in mind that the total number of usable DMX addresses in a so-called ‘DMX
universe’ is limited to 512.
You can connect an additional DMX-chain with up to 32 DMX devices to the direct DMX
output DMX OUT. If you use this output, the LINK OUT / TERMINAL switch must be in the
LINK OUT position (released). If the device itself terminates a DMX chain, the LINK OUT / TER‐
MINAL switch must be in the TERMINAL position (pressed). Then a termination resistor is con‐
nected.
