Introduction 7

Using for the first time

Before applying power to the device:

• Carefully review ”Safety information” starting on page 4.

• Check that the local AC mains power voltage is within the range given
on the product’s serial number label.

• For the DMX 5.3 Splitter, if the supplied mains plug (cord cap) does not
match your local power outlets, cut it off and install a suitable plug on
the power cable (see ”Power cable and plug” on page 13).

• For the RDM 5.5 Splitter, install the supplied Neutrik PowerCon power
input connector on a suitable power cable and either install a mains plug
or hard-wire the device to a building electrical installation (see ”Power
cable and plug” on page 14).

Functionality

Both the DMX 5.3 Splitter and RDM 5.5 Splitter transmit DMX signals. The
RDM 5.5 Splitter also provides bidirectional transmission of an RDM
signal on the data link.

Splitting the data link

Branching a DMX or DMX/RDM data link using a passive split such as a
‘Y’ connector is likely to cause data transmission problems and is
therefore not recommended. Martin Splitters allow the data link to be split
into up to 5 branches:

not allowed

AC power

Warning! For protection from dangerous electric shock, the device
must be grounded (earthed). The local AC power source must have
both overload and ground-fault (earth fault) protection.

Warning! Power socket outlets or external power switches used to
supply the DMX 5.3 Splitter with power must be located near the
device and easily accessible so that the device can easily be
disconnected from power. In an emergency, the RDM 5.5 Splitter can
be disconnected from power by removing the Neutrik PowerCon
power input connector

Important! Only insert or remove a live Neutrik PowerCon connector
to apply or cut power in an emergency, as doing so may cause
arcing at the terminals that will damage the connectors.

AC operating range

The power supply units in both the DMX 5.3 Splitter and RDM 5.5 Splitter
are fully auto-sensing and these devices can be connected to AC power
at 100-240 V nominal at 50/60 Hz. Do not connect to power at any other
voltage or frequency.

Power cable and plug

Martin DMX 5.3 Splitter

The 5.3 DMX Splitter is supplied with a hard-wired, EU color-coded power
cable with a US-type AC mains power plug. If this plug is not suitable for
your local power outlets, cut the plug off the end of the cable and either
hard-wire the Splitter to the building’s electrical installation providing an
easily accessible power on/off switch close to the device, or replace it with
a grounding-type (earthed) power plug that suits the local power outlets.
Following the power plug manufacturer’s instructions, connect the
green/yellow wire to ground (earth), the blue wire to neutral, and the
brown wire to live.

Relaying power to other devices

Warning! The current load of all devices connected to AC mains
power in one interconnected chain via the RDM 5.5 Splitter’s power
throughput outlet must not exceed 19.6 amps.

Terminals

Devices can be linked in a chain, power throughput to power input, so that
they all draw AC mains power via the RDM 5.5 Splitter’s Neutrik
PowerCon power throughput socket, but certain points must be
respected:

• Power cable that meets the requirements specified on page 5 of this

manual must be used to connect the RDM 5.5 Splitter to AC mains
power and to connect all the devices in the chain to each other.

• A light-grey Neutrik PowerCon NAC3FCB cable-mount connector must

be used to draw AC mains power from the RDM 5.5 Splitter’s power
throughput socket and a blue Neutrik PowerCon NAC3FCA cable­mount connector must be used to supply power at the RDM 5.5
Splitter’s power input socket.

• No matter what the AC mains power voltage is, the current draw of all

the devices that draw AC mains power in one interconnected chain
from the power throughput socket of an RDM 5.5 Splitter that is
connected directly to AC power must not exceed 19.6 amps total.

AC power 15

Data connections and
setup

The Martin DMX 5.3 Splitter uses 3-pin XLR and the Martin RDM 5.5
Splitter uses 5-pin XLR sockets for all data connections: in, optically
isolated, optically isolated, thru and out.

Pins 4 and 5 in 5-pin XLR connectors are not used by DMX or RDM
signals, but if you intend to use pins 4 and 5 in the RDM 5.5 Splitter’s 5-pin
sockets for any other purpose, note that these pins are connected from
the in to the thru socket, but that there is no connection to pins 4 and 5 of
the out sockets.

Data input

Connect the data link cable from the controller to the in socket on the
Splitter using a female XLR cable connector.

Data throughput

The main data link daisy-chain can be continued at the thru socket using
a male XLR cable connector. The signal that is relayed from the in to the
thru socket is not amplified or processed in any way and is available even
if the Splitter is not powered.

DMX termination

The DMX termination button (see Figure 8) on the front of the Splitter must
be:

• pressed in to activate termination if you do not connect devices to the

thru socket, and

• not pressed in if you continue the data link from the thru socket.

16 Martin DMX 5.3 and RDM 5.5 Splitters user manual

The LED under the termination button lights when DMX termination is
applied.

Data output

The Splitter’s out 1 - out 5 sockets provide five amplified, buffered,
regenerated and optically isolated outputs of the data signal present at
the in socket.

Termination

button

Figure 8: DMX termination (5.5 Splitter illustrated)

You can create up to 5 branches on the data link by connecting DMX
cable to the Splitter’s out sockets using XLR male cable connectors. Each
branch can have up to 32 devices connected and must be terminated at
the end of the branch by inserting a DMX termination plug in the last
device’s DMX output. Unused outputs on the Splitter do not need to be
terminated.

RDM (Martin RDM 5.5 Splitter)

The Martin RDM 5.5 Splitter relays both DMX and bidirectional RDM
signals on the data link.

Removing non-DMX signals

All Martin DMX-controlled products monitor the data signal and filter out
any data that they are not designed to accept. Martin products that do not
support RDM will therefore not be disturbed if an RDM signal is present
on the data link. However, there are DMX-controlled products in use that
do not filter the data signal. These products may behave unexpectedly if
they receive an RDM signal.

Data connections and setup 17

To solve this problem, the RDM 5.5 Splitter can be used as a data signal
filter. If the dmx only button is pressed in, the RDM 5.5 Splitter will
remove all data signals apart from DMX from the five out sockets. Note
that pressing in the dmx only button will not affect the thru socket, which
will continue to relay unmodified data signals from the in socket.

‘dmx only’

button

Figure 9: DMX only

If your installation contains a mixture of (a) devices that use or are
unaffected by RDM and (b) devices that are disturbed by RDM, use
separate Splitters to send DMX/RDM to the devices in group (a) and to
send only DMX to the devices in group (b).
