IMPORTANT:
The manufacturer will not accept liability for any resulting damages caused
by the non-observance of this manual or any unauthorised modication to the
equipment.
• Never let the power-cable come into contact with other cables. Handle the power-cable
and all mains voltage connections with particular caution!
• Never remove warning or informative labels from the equipment.
• Do not open the equipment and do not modify the equipment.
• Do not connect this equipment to a dimmer-pack.
• Do not switch the equipment on and off in short intervals, as this will reduce the
system’s life.
• Only use the equipment indoors.
• Do not expose to ammable sources, liquids or gases.
• Always disconnect the power from the mains when equipment is not in use or before
cleaning! Only handle the power-cable by the plug. Never pull out the plug by pulling the
power-cable.
• Make sure that the available voltage is between 220v/240v.

Operation modes:
The Gemini has three modes of operation as follows:
1, Sound active mode
To select sound active mode set dipswitch 10 to the ON position. You can now use the sensitivity
control on the back panel to set the required sound level. With no music present, the laser diode
will turn OFF and will come back ON as soon as the music starts again.
2, Auto mode
To select auto mode, set dipswitches 9 and 10 to the ON position and all others to OFF. The
Gemini will now cycle through all it’s internal geometric patterns. In this mode the laser diode will
remain on constantly until the power is turned OFF or the mode is changed.
3, DMX mode
To select DMX mode, set all dipswitched to the OFF position. You can now set the required DMX
address using dipswitches 1 to 9. Please refer to the chart below for DMX functions.

Equinox Gemini Laser Operation modes

DMX Control Mode
Operating in a DMX control mode environment gives the user the greatest exibility when it comes
to customising or creating a show. In this mode you will be able to control each individual trait of
the xture and each xture independently.
Setting the DMX address
The DMX mode enables the use of a universal DMX controller. Each xture requires a
“start address” from 1- 511. A xture requiring one or more channels for control begins to read the
data on the channel indicated by the start address. For example, a xture that occupies or uses 7
channels of DMX and was addressed to start on DMX channel 100, would read data from
channels: 100,101,102,103,104,105 and 106. Choose a start address so that the channels used
do not overlap. E.g. the next unit in the chain starts at 107.
Set the start address using the group of dip switches located usually on the back of the xture.
Each dipswitch has an associated value. Adding the value of each switch in the ON position will
provide the start address. Determining which switches to toggle ON given a specic start address
can be accomplished in the following manner. By subtracting the largest switch value possible
from the selected start address until zero is achieved.

Equinox Gemini Laser DMX control mode

DMX-512:
• DMX (Digital Multiplex) is a universal protocol used as a form of communication between
intelligent xtures and controllers. A DMX controller sends DMX data instructions form the
controller to the xture. DMX data is sent as serial data that travels from xture to xture via the
DATA “IN” and DATA “OUT” XLR terminals located on all DMX xtures (most controllers only have
a data “out” terminal).
DMX Linking:
• DMX is a language allowing all makes and models of different manufactures to be linked together
and operate from a single controller, as long as all xtures and the controller are DMX compliant.
To ensure proper DMX data transmission, when using several DMX xtures try to use the
shortest cable path possible. The order in which xtures are connected in a DMX line does not
inuence the DMX addressing. For example; a xture assigned to a DMX address of 1 may be
placed anywhere in a DMX line, at the beginning, at the end, or anywhere in the middle. When a
xture is assigned a DMX address of 1, the DMX controller knows to send DATA assigned to
address 1 to that unit, no matter where it is located in the DMX chain.
DATA Cable (DMX cable) requirements (for DMX operation):
• The Equinox Gemini laser can be controlled via DMX-512 protocol. The DMX address is set on
the back of the unit. Your unit and your DMX controller require a standard 3-pin XLR connector for
data input/output (gure 1).
Figure 1
Also remember that DMX cable must be daisy chained and cannot be split.

Further DMX cables can be purchased from all
good sound and lighting suppliers or Prolight
dealers.

CABL10 – 2M
CABL11 – 5M
CABL12 – 10M

Notice:
• Be sure to follow gures 2 & 3 when making your own cables. Do not connect the cable’s shield
conductor to the ground lug or allow the shield conductor to come in contact with the XLR’s outer
casing. Grounding the shield could cause a short circuit and erratic behaviour.
Special Note: Line termination:
• When longer runs of cable are used, you may need to use a terminator on the last unit to
avoid erratic behaviour.
Using a cable terminator (part number CABL90) will decrease the possibilities of erratic
behaviour.
5-Pin XLR DMX Connectors:
• Some manufactures use 5-pin XLR connectors for data transmission in place of 3-pin. 5-Pin
XLR xtures may be implemented in a 3-pin XLR DMX line. When inserting standard 5-pin
XLR connectors in to a 3-pin line a cable adaptor must be used. The Chart below details the
correct cable conversion.
Termination reduces signal transmission problems
and interferance. it is always advisable to connect a
DMX terminal, (resistance 120 Ohm 1/4 W) between
pin 2 (DMX-) and pin 3 (DMX+) of the last fixture.

Class 3B Laser Safety Guide
Warning
Class 3B Lasers have the potential to harm eyesight if viewed directly and can also be
harmful at long distances.
Any unit that contains a laser diode has to be classied depending upon the light output that
someone may be exposed to. All laser products are classed as dened in the
Laser Product Safety Standard (BS/EN 60825.1). The classes range from the safest, which is
Class 1, through to the most hazardous, which is Class 4. A laser diode that emits more than 5mW
of light and less than 500mW can be classied as a Class 3B product.
Operation and installation Notes
Laser effects should only be installed and operated by persons who have been trained in how to
operate laser effects safely.
Laser effects should be located in a safe and secure position in the venue, so that once installed it
cannot be tampered with by unauthorized users.
Before operation the path of the laser beams should be taken into account in respect to how the
beams will scan the viewing audience.
If direct audience scanning is to be used then the laser energy levels from the effects needs to be
calculated.
Health
If used responsibly and in accordance with the relevant guidance issued by the Health and Safety
Executive a laser effect will not present a hazard to those viewing the show as long as the laser
beams are projected over the heads of the viewing audience. When laser effects are directed into
the audience area it becomes difcult to tell if the effects are causing harm.
Class 3B laser beams can be harmful to eyesight if viewed directly The injury that a Class 3B
laser can inict is dependant upon several varients, including the amount of time the laser beam
enters the eye for, the intensity of beam and what part of the eye that actually receives the beam.
The part of the eye which is most susceptible to receive damage from the beam is the retina. The
retina is the part of the eye that receives the light signals that are sent to brain. All light entering
the eye gets focused onto the retina.
Normal light sources including halogen lamps are not usually harmful to view. Lasers are different
in the fact that they can get the beam focused down to a very small point on the retina which can
burn holes on the back wall of the eye. There are no pain receptors on the retina and the damage
can happen in less time than it takes for a person to blink so the person will be not be aware of
any damage taking place. Damage to the retina cannot be repaired and therefore is permanent.
Symptoms include severe loss of sight and unnoticeable vision loss.
