IMPORTANT
Installer and Users please note:
These instructions should be read carefully and left
with the user of the product for future reference.
Installation
Fix the Microbeam 100 with the hanging bracket provided. To
conform to Health & Safety Regulations, a safety chain must also
be employed.
The Microbeam 100 must be installed by a competent
electrician in accordance with the current IEE wiring
regulations.
Connect the Microbeam 100 to the mains supply with the
lead provided. The wires are colour-coded as follows:
• Brown = Live (phase)
• Blue = Neutral
• Green/Yellow = Earth
• The Microbeam 100 must be earthed for safe and reliable
operation.
The supply must be fitted with an isolating switch, or plug and
socket, and protected by fuse or circuit breaker rated at between
6A and 16A. If the Microbeam 100 circuit is connected via an
MCB then it is recommended that a time-delay MCB is used (Type
3 or Type C to BS3871). This will reduce the possibility of
"nuisance tripping" due to the large inrush current of the halogen
lamp.

illuminating.
It is also possible to connect the Microbeam 100 to a
switching pack such as the NJD SP10000 but this is not
recommended. If connecting via a power pack, the outputs of the
power pack should be de-rated by 50% from its “resistive load”
capacity to allow for the large inrush current of the halogen lamp.
This symbol means that in order to reduce the risk
of fire, the Microbeam 100 should be installed
more than 0.5 metres from any object that it is

User Guide Microbeam 100
The Microbeam 100 should not be connected to a dimming pack
or light dimmer. The Microbeam 100 is an inductive load.
Adjust the hanging bracket until the light beams are in the
best position. The Microbeam 100 may be moved whilst it is
operating provided that it is done carefully, the lamp is most
vulnerable mechanical damage immediately after it has been
switched off, before it has fully cooled. It is recommended that the
Microbeam 100 is allowed to cool for 5 minutes after switching
off before moving.
Changing the lamp.
Disconnect from the mains supply. Unscrew the fixing knob
from the lamp cover on the front of the product and withdraw the
lamp assembly. Remove the lamp from the fixing clip and remove
the connector from the lamp. Replace with a new lamp, type A1/
231, being careful not to touch the glass envelope of the lamp.
Connect the lamp connector to the lamp and replace in the fixing
clip. Replace the lamp cover and tighten the fixing knob.
Changing the fuse.
Occasionally, when the lamp fails the fuse may also blow. If
this occurs, replace with a new fuse type 20mm × 5mm 1.6 Amp
antisurge, high breaking capacity. This type of fuse has a ceramic
case. Do not replace with any other type or value of fuse. If the
new fuse blows consult a dealer. The fuse is located next to the
incoming mains cable.
Focusing.
To focus slacken the focusing control on the front of the unit,
move forwards or backwards as required, and re-tighten the
screw when the best image is obtained.
Cleaning.
The Microbeam 100 should be cleaned periodically as the
light output will become less intense as smoke fluid residues build
up on the mirror and lenses. Disconnect from the mains supply
and remove the cover. Clean the lens and the mirror using a soft
lint-free cloth and methylated spirit, isopropyl alcohol or hi-fi
cleaning fluid. Also, make sure that the fan is not becoming
obstructed - use a brush to remove any build-up of dust.
The Microbeam 100 may be operated in one of fi different
Modes.
Independent (internal microphone)
The Microbeam 100 will move to each bass beat, going
through a sequence of patterns at random, including up/down,
side-to-side, square, octogon, diamond, figure-of-eight, random
and chevron, along with colour and gobo changing.
Synchronized (internal microphone)
The Microbeam 100 will perform the above pattens either
synchronized together, or with the movement mirrored. In
addition, the colours and gobos will operate in one of three
modes: random, synchronized or chasing. The movement can be
controlled by setting the control switches in order that two rows
of Microbeam 100s can be set up opposed to each other, and will
continue to move in synchrony. The Microbeam 100 can be
synchronized with IQ-500, IQ-250 and Datamoon.
Externally controlled from IQ-MX80, IQ-MX60, IQ-MX40,
Merlin, or any DMX output controller.
The Microbeam 100 can be controlled from the Merlin, or
any of the NJD IQ-MX range of controllers or any lighting desk
with DMX or 0-10V analogue outputs.

Synchronized operation without a controller
To synchronize Microbeam 100s without a controller, connect
a DMX lead from the DMXout jack on the first Microbeam 100
to DMXin on the second, from DMXout on the second
Microbeam 100 to DMXin on the third, and so on.

DMX line termination is performed automatically by the
Microbeam 100. DMX leads must never be joined (apart from
end-to-end) or split. Using a 2-to-1 splitter or similar will prevent
the system working.
Setting the DIL switches.
To obtain the the correct movement, the switches on the back
of each Microbeam 100 must be adjusted to tell it which DMX
channel it is set to. The switches are labelled 128, 64, 32, 16,
8, 4, 2 and 1. These set the DMX address.
The Microbeam 100 at the start of the chain (the one with no
plug in its DMXin socket) acts as master, the others act as
slaves, controlled by the master. Set the DIL switches on the
master as described above in "independent operation".
Set the DIL switches on the slaves as follows:
Either: If it is intended that all the Microbeam 100s should
operate identically, set all the DIL switches OFF on the slaves.
Or: To obtain four channel colour changing sequences, set
the DIL switches as shown in the table below: (Microbeam 100s
5 to 8 repeat the actions of numbers 1 to 4)

Movement may be reversed by setting the "X-REV" switch.
Reversing the movement is useful if two or more microbeam
100s are facing each other. Reversing the direction of movement
makes the beams from both units move the same way in the air.
The DMX system is a high-speed digital data system, which
can transmit all the information required for light dimmers, multimotor lighting effects etc. down a single cable. It was invented in
1986 by the United States Institute of Theater Technicians for the
control of dimming theatre lighting, and has since been adapted
for the control of intelligent lighting.
The Microbeam 100 outputs a DMX signal when operating
from its own microphone, which can be used to synchronize other
Microbeam 100s. Up to 32 units that can be connected to the
DMX signal, but it is not recommended that the total cable length
should exceed 250m.
Each unit connected to the DMX signal is given an address,
and it compares this to the data being sent on the DMX cable, so
it can determine which data is addressed to it. It then uses this
data to move a motor or set a brightness level as required by the
controller.
As the DMX system can transmit as much information as
512 analogue control wires down a single cable, it has to
transmit very quickly, in fact, at a frequency 12 times higher than
the highest audio frequency. Anyone who has used long leads for
audio will realize that it is difficult to do without losing the higher
frequencies. To make the DMX system work at such high
frequencies, it requires special circuitry and special cable. Cable
can be designed to pass high frequencies with no loss if it has the
correct resistance connected at each end, this resistance is
called the characteristic impedance of the cable. DMX cable has a
characteristic impedance of 120W . All NJD DMX products fitted
with ¼" jacks are designed to ensure that the resistors are
connected automatically. Without them, the signal reflects off the
end of the cable and interferes with the new data coming the
other way. If the cable is not correct, the system will not work.
Most good quality low-capacitance screened twisted pair cables
will work, but twin individually screened will not. Also, if the cable
is split or joined other than end-to-end, the system will stop
If making your own leads, it is important to use good quality
connectors and make sure that the soldering is of a high
standard.
Using the Microbeam 100 with NJD's dedicated DMX
controllers (IQ-MX range)
To connect to a controller: Connect a DMX lead from the
DMXout from the controller to DMXin on the first Microbeam
100. Connect a DMX lead from the DMXout jack on the first
Microbeam 100 to DMXin on the second. Connect from

DMXout on the second Microbeam 100 to DMXin on the third,
and so on. DMX line termination is performed automatically by the
Microbeam 100.
DMX leads must never be joined (apart from end-to-end) or
split. Using a 2-to-1 splitter or similar will prevent the system
working. Refer to the User Guide accompanying your controller for
information on how to set the switches.
The X-REV switch reverses the movement in the x direction.
Use this to make the Microbeam 100 move the same way as the
controller joystick, which depends on whether the Microbeam 100
is facing towards or away from the controller.
Connecting to Merlin or any Lighting control desk with
DMX output.
The DMX system has 512 addresses, each address can be
the brightness of a single dimmer, or a position on a motor.
Because the Microbeam 100 controls 3 motors and the lamp, it
requires four DMX addresses.
The Microbeam 100 can be programmed to any address
from 1 to 255 in steps of two, so there can be up to 64
Microbeam 100s on a controller. Any number of Microbeam
100s can be assigned to each channel or address. If two
Microbeam 100s are assigned to the same address then they will
perform identically.
Each Microbeam 100 occupies four DMX channels. The
switches are labelled 128, 64, 32, 16, 8, 4 and 2. Add up the
numbers of the switches that are on and add 1, to give the start
address.
The X-motor appears at the start address, the Y-motor at
start address plus 1, gobo/colour motor at start address plus 2
and blackout/lamp control at start address plus 3. (i.e. If switches
32 and 8 are ON, then start address is 32+8+1 = 41, the X
motor is on channel 41, the y-motor on channel 42 and the gobocolour motor on channel 43, channel 44 controls the blackout
and lamp switching.)
The X-REV switch reverses the movement in the x direction.
Use this switch to make the Microbeam 100 move the same way
as the controller joystick, which depends on whether the
Microbeam 100s is facing towards or away from the controller.
This switch has no effect opn the DMX address set on the other
7 switches.
The DMX dimmer levels control the movement as follows:
X-motor: 0 is extreme left (right for X-REV selected), 255 is
extreme right (left for X-REV selected), 128 is central.
Y-motor: 0 is reflected back down lens, 128 is central, 255 is
32 - 63 is yellow tunnel
64 - 95 is cyan dots
96 - 127 is pink star
128 - 159 is green triangle
160 - 191 is red segments
192 - 207 is blue spiral
208 - 255 is white circle
The gobo is always centralized.
Direct Analogue control (0-10V)
The dish rotation and dimmer may
be controlled directly using analogue
channels 1 and 3 and 4. The microphone
circuitry is disabled.
Set the DMX address switches with switch 128 ON and all
other switches OFF.
The 0-10V inputs control the Microbeam 100 as follows:
Channel 1: (pin 3) moves the beam left to right
Channel 2: (pin 5) moves the beam up and down
Channel 3: (pin 4) controls the colours and gobos.
Channel 4: (pin 1) controls the blackout shutter and lamp.
The 0-10V dimmer levels control the movement as follows:
X-motor: 0 is extreme left (right for X-REV selected), +10V is
extreme right (left for X-REV selected), +5V is central.
Y-motor: 0 is reflected back down lens, +5V is central, +10V
more than one input is enabled at once, the Microbeam 100 will
sequence through the selected modes in turn.
When all four channels are off (or all four switches off on the
AR1) the lamp is turned off.
Voltage Control
The Predator HX may be controlled by two analogue channels
from a lighting desk such as the Stage 12 or the Fade-4.
Set the DMX address switches with switch 32 ON and all the
other switches OFF.
Connect the 0-10V input to channels 1 and 3 of the 5-pin DIN
socket.
X-REV
Channel 1 controls the pattern and channel 3 controls the
colour, or the colour chasing mode. The levels that select various
patterns and colours are explained overleaf.
Additionally, if required, channel 4 can be used to override the
sound circuitry for applications where there is no sound available.
Pulsing the voltage from 0V to 10V and back to 0V will advance
one step in the pattern.
