2. INTRODUCTION

Nexus Dual Split RDM is a DMX & RDM splitter pro­vided with eight outputs, which can be connected
to any of the two inputs. Each of its ten signal ports
is optically isolated.
With its 128x128 full color pixels OLED display, a
navigation button and a push button for each of

the signal ports, the conguration of the splitter is
quick and easy to do in spite of the device’s versa­tility. An RGB LED next to each of the signal ports
lets you know at a glance whether a good signal is

available at any given port.

If you need to know more about the incoming DMX

signal, the OLED display will show you the refresh

rate and the number of received channels when

you push the button next to any of the two inputs.

Furthermore, a graphical overview of the received

channel values is available.

The various output modes of the LF-SP28-3P also

allow for using the device as an accelerator or de­celerator.
The Nexus Dual Split RDM is available with 3-pin or

5-pin XLR connectors.

4. SAFETY INFORMATION

Consider the following notes mandatory when you

set up, connect and use the Nexus Dual Split RDM.
This product is approved for professional use only,
it is not intended for household usage. Read this

manual before operating the device, follow the

safety precautions closely and pay attention to all

warnings given in this manual.

Use this device only in accordance with local laws
and regulations.

Safety Precautions

• Disconnect the device from the AC power sup­ply before removing any cover or part, including

fuses, even when not in use.

• Ensure that the device is electrically connected
to ground (earth).

• Use only a source of AC power supply that com­plies with local building and electrical regula­tions and which has both overload and ground­fault (earth fault) protection.

• Before using the device, check that the pow-

er distribution equipment and cables are in

perfect condition and rated for the current

required by all connected devices.

• Isolate the device from power supply immedi­ately if the power cable or the power plug are

in any way damaged, defective or wet, or if they

show signs of overheating.

• Do not expose the device to rain or moisture.

• Do not operate the device if any cover or com-

ponent is missing, damaged or deformed.

• Provide unrestricted airow around the device.

• Do not operate the device if the ambient tem-

perature exceeds 55°C (131°F).

• Do not modify the device in any way not de­scribed in this manual.

• Do not attempt to bypass any fuse. Replace any
defective fuse with one of the specied type

and rating only.

• When suspending the device, ensure that the
supporting structure and all hardware used

can hold at least 10 times the weight of all

devices suspended together.

• When suspending the device, install a second-

ary attachment such as a safety cable that is
approved by an oicial body such as, e.g. TÜV
(German Technical Monitoring Association),
a safety attachment for the total weight it
secures. The safety cable must comply with
EN 60598-2-17 section 17.6.6 and be capable of
bearing a static suspended load 10 times the

weight of the device.

• Make sure that any external cover and rigging
hardware is securely fastened.

• Provide an adequate clearance underneath

the work area and a stable platform whenever
installing, servicing or moving an overhead

device.

• Do not use the device in areas where it is ex­posed to direct sunlight.

• Do not use the device in areas that are consid-

ered to be “highly inammable”.

6. DMX CONNECTIONS

Mains Connection

The user must supply a suitable power cable. He
may then either hard-wire the power cable to the
building’s electrical installation, providing an easily
accessible power on/o switch close to the device,

or install on the power cable a grounding-type

(earthed) mains plug that is suitable for the local
power outlets, following the power plug manufac­turer’s instructions. Consult a qualied electrician,

if you have any doubts about the proper installation.

A blue powerCON cable mount connector must be
used to supply power at the LF-SP28-3P ’s power
input socket.

Depending on the version, the Nexus Dual Split
RDM is equipped with 5-pin or 3-pin XLR connectors.

XLR Connectors

The DMX inputs are fully isolated. All outputs are
isolated transmitters with a bias network for RDM

operation. Each output port is individually optically

isolated, meaning that it is totally isolated from the
other output ports and from the input section.

Warning! For protection against dangerous
electrical shocks, the device must be grounded
(earthed). The local AC power source must be sup-

plied with both overload and ground-fault (earth
fault) protection.

Important! Only attach or remove a powerCON
connector while it is connected to the mains to
apply or cut power in an emergency situation, as
by doing so may cause arcing at the terminals that
will damage the connectors.

7. SETTINGS AND MENU

General Navigation

The navigation buttons is the primary means for
navigating through the menus. Most of the menus
arrange items vertically. In those menus, Press the
down button to select the item below the currently
selected item or Press the up button to select the
item above the currently selected item. In menus
that arrange items horizontally (e.g. text elds), Press
the down button means “to the right” and counter
Press the up button means “to the le”.

Other than that, the right button also functions as a

push button. This button is generally used to conrm
a selection or to navigate to a selected submenu.
This manual will also refer to pushing the right but­ton as “push [OK]” or “push the [OK] button”.
The le button (depicted on page 7), which is gener­ally used to dismiss a selection or to exit a menu.
By keeping the le button pressed for at least two
seconds, you can always navigate to the Home
Screen. From the Home Screen, the menu is
launched by simply pushing the [OK] button.

Below, the following notation is used to describe lo-

cations in the menu: Home > Menu > Sub menu > …
