POWER AND WIRING REQUIREMENTS
The Gantom Juni DMX has a maximum wattage of 11W and an operating voltage range of 12-24VDC.
The Gantom Juni DMX includes a single locking connector which combines both power and data into
one compact cable. This connector is compatible with our Gantom Pro Cable System, including our G8
Power/Data Distribution Box. A single cable for power and data greatly simplifies installation and the
locking connector gives a secure connection for long term use. This makes the Gantom Pro Cable
System ideal for permanent installations. For more information on this system, please visit
https://www.gantom.com/accessories/gantom-pro-cable/
Note: all fixtures must be installed with the low voltage supply power OFF. Hot
plugging (connecting to a live power supply) is not supported.
Hot plugging a fixture into a system with a running power supply will increase the load on the power
supply, which can generate voltage spikes that more than double of the standard input voltage. This
causes an out-of-spec and out-of-warranty voltage condition which may result in damage to the fixture.
While Gantom fixtures have internal protections against voltage spikes, it is recommended that
installers handle them with care to prevent these spikes from happening in the first place.
Installing all fixtures in the system before turning on power to the low voltage
power supply assures that the power supply has a “soft start” which is free from
harmful voltage spikes.

MOUNTING INSTRUCTIONS
The Gantom Juni micro framing projector comes with an aluminum mounting yoke pre-installed. It is
meant to be used with ¼” size hardware, but please note that mounting hardware is not included with
the fixture. The yoke has a center hole (1) and a curved slot (2). Install a screw in the center hole first,
then loosely screw down a second screw through the curved slot. Rotate the fixture to the appropriate
angle and then finally tighten down both screws all the way to lock the fixture in place.

FOCAL ADJUSTMENT
First, loosen the three set screws on the lens tube cover and remove the lens tube cover.
Power on the fixture. Be sure to never look directly at the LED while the fixture is on.
Now, move the primary optic as close to the LED as possible and the secondary optic as far from the LED
as possible on the optic slider rails. Slowly begin sliding the secondary optic toward the LED until the
projected image comes into focus. This will be the narrowest focused beam the fixture can achieve.
To widen the beam move the primary optic forward about 1 mm, and then move the secondary object
backward along the optic slider rails toward the LED until the beam comes back into focus. Repeat this
process until you have your desired projection size. At the maximum beam size, the primary and
secondary optics will be touching each other at about 1/3rd of the length of the optic slider rails.
When you have finished focusing the lenses, replace the lens tube cover and tighten the set screws back
down to hold the lens tube in place.

GOBO INSTALLATION
A gobo can be a great way to add texture and dimension to your application. The Gantom Juni DMX
micro framing projector accepts glass and stainless steel gobos with an outer diameter of 19mm. The
maximum image size for patterns is 15mm and the maximum image size for text is 10mm. Both stainless
steel and full color glass gobos are available to fit the Gantom Juni DMX. Custom stainless steel and full
color glass gobos are available through Rosco. Please see http://www.rosco.com/gobos/ for more
information on how you can order your own.
To install a gobo slide, first make sure that your fixture is powered off. Loosen the three set screws on
the lens tube cover and remove the lens tube cover.
Next, remove the lens tube by unscrewing it from the fixture.

Gantom Juni DMX User Guide Version 1.0 –3/25/2021
Unscrew the gobo retainer from the gobo holder ring.
Insert your gobo slide into the gobo retention hole, it should rest easily on a ledge that is inside the hole.
Next, screw the gobo retention ring back into the hole until it is firmly seated and holding the gobo in
place.
Once the gobo is in place within the retainer system, reattach the lens tube, focus your optics to your
desired effect, then reattach the lens tube cover.

SHUTTER ADJUSTMENT AND LOCKING
The Gantom Juni DMX features 4 independently adjustable framing shutters which are perfect for
creating rectangles, triangle, trapezoids, slits, or irregular shapes for selective lighting. This gives you the
ability to add a crisp angular edge to your beam. This feature is perfect for highlighting a table or piece
of art with minimal light spill.
With the light powered on, use the handles to adjust the placement of the shutters. Note that the side
which is being adjusted will be mirrored and inverted on the light output. This means that when you
adjust the shutter on the RIGHT side of the fixture, the image will be adjusted on the LEFT side. When
you adjust the shutter on the TOP side of the fixture, the image will be adjusted on the BOTTOM side.
Once the shutters are adjusted, you can lock them in place by tightening one of the highlighted set
screws. Note that there are 3 set screws around the fixture, but only one needs to be tightened to lock
the shutters in place.

CONFIGURING THE GANTOM JUNI DMX
Due to its compact size, the Gantom Juni DMX cannot use a physical
DIP switch for addressing. Instead, the Gantom Juni DMX is
programmed using the DMX Programmer App by Gantom or by using
the DarkBox Programmer V2 programming device (part# DB32,
pictured right). In addition to setting the DMX starting address for the
fixture, this will allow you to save a default color and brightness for the
fixture if the application does not require any DMX control.
Configuring light fixtures with the DarkBox Programmer V2 Device:
For details on how to configure your fixture using the DarkBox
Programmer V2, please consult the user guide for that product. The
DarkBox Programmer V2 device is the easiest and most reliable way to
configure Gantom fixtures and is the preferred option when available.
Configuring the light fixture with the DMX Programmer App:
When the DarkBox Programmer V2 standalone programming device is unavailable, it is also possible to
configure the settings of the device using our free app for iOS and Android devices.
What you need:
oA CB107 Pro Cable Programming Adapter
oAn Android or iOS device for running the Gantom Programmer app. Please note that a
headphone port is required to connect to the device to the fixture. The iPhone7 does work
with, but you will need to use the headphone port adapter that is included with the phone.
oA male-to-male 3.5mm audio 3.5mm cable. This is the same type of cable that you would use to
connect your Android or iOS device to headphones or to an AUX port.
oPower supply for the fixture. All Gantom fixtures accept 12v DC power. We recommend using
one of our PowerPak Mini units if you are just going to power a single fixture.
oThe free DMX Programmer app by Gantom. This can be found by searching “Gantom” in iTunes
for an Apple device or Google Play for an Android device
First, open the DMX Programmer app by Gantom. The app will open to the screen you see here.
From this screen, select Generic Console. (note: a Gantom Juni DMX menu option
may be added to the app at a later date)
The app will then provide you instructions on how to connect the light fixture to
the tablet or smartphone. Please note the order in which the cables should be
connected. First connect the headphone cable to the light fixture and to the
tablet/smartphone. Next, connect the power to the fixture. When prompted by
the app, tap the “Next” button and you will be taken to the control screen.

Gantom Juni DMX User Guide Version 1.0 –3/25/2021
OTHER OPTIONS SCREEN
If you hit the “Other Options” button on the control screen, the following menu appears:
oReset - selecting this will reset the fixture to its default
factory settings. Do this if you are running into programming
issues.
oToggle Silent Bootup –By default, the fixture will flash to
report its DMX address when it is powered on. tapping the
“Toggle Silent Bootup” option will turn address reporting at
startup on or off.
oLock/Unlock 9600 –The Gantom Juni DMX fixture can
listen to either a standard DMX signal OR to the special
control signal that comes from the app. Lock 9600 will turn
OFF the fixture’s ability to listen to DMX and ONLY allow it to
be controlled through the app interface. For most applications
it is recommended that you keep “UNLOCK 9600” selected.
BOOT SEQUENCE FLASHING
When the fixture first receives power, before it enters normal operation, it will first report its channel
mapping profile and second report its DMX address through a sequence of flashes.
By default, the DMX starting address will be 1. The Gantom Juni DMX will flash several times when it is
powered on to indicate its starting address. If the Gantom Juni DMX is assigned to address 245 it will
report its address by flashing 2 times, pausing briefly, then flashing 4 times, pausing briefly, then flashing
5 times. If it is assigned to DMX address 038, it will flash 3 times, pause briefly, then flash 8 times
TURN OFF/ON boot sequence flashing: You may not want your fixture to report its channel mapping
profile and address every time it receives power. In order to toggle the boot sequence flashes on/off,
follow these steps. With the fixture connected to the DMX Programmer App, select the “Generic
Console” profile. Once the control screen appears, power cycle the Gantom Juni DMX. Next, tap the
“Other Options”, then tap the “Toggle Silent Bootup” button. The light should blink to indicate that it
has received this new setting.

Gantom Juni DMX User Guide Version 1.0 –3/25/2021
STANDALONE OPERATION
Some applications may not require live DMX control. In order to configure your Gantom Juni DMX for
standalone operation, all you must do is use the CH1 slider on the Generic Console control screen to set
the desired intensity level. Once the light has the desired output, tap the “STORE AS DEFAULT” button at
the lower left portion of the screen to save this setting directly into the light fixture. Now, when the light
fixture receives power it will automatically go to this newly saved DEFAULT setting once it’s boot
sequence is complete. Please note that if DMX signal is passed to the fixture while it is operating in
standalone mode, the DMX signal will override the standalone setting.
DMX CONTROLLED OPERATION
The Storm Form DMX was designed for use with standard DMX512 control systems. The Gantom Juni
DMX occupies a single DMX channel and can be given any DMX starting address from 1-512. Please note
that the Gantom Juni DMX does not feature any RDM functionality.
ADDRESSING YOUR FIXTURE
To set the DMX address, first connect the Gantom Juni DMX to the
DMX Programmer app by Gantom as was outlined earlier in this
document. With the Generic Console control screen open, you should
have full control of the fixture using the CH1 slider. If the light fixture
is connected to the app but is not responding, try power cycling the
light fixture.
Once you have verified that the light fixture is responding to control
signal from the app, tap the number field next to the word “Address”.
A new screen will pop up, prompting you to enter a DMX address.
After you enter your desired DMX address, the app will return to the
Generic Console screen. Finally, you must hit the ASSIGN ADDRESS
button in order to save the new address into the fixture. Hitting the
“Save” button will not save anything to the light fixture’s memory.
