SGM Uploader cable
The SGM USB to DMX cable is an accessory used mainly to update the fixture
with the latest SGM firmware.
Please refer to page 24 to see how to update the fixture with the latest firmware.
The SGM Uploader cable is also used for controlling the DMX values channel by
channel through the Firmware Uploader Tool software (available for download
at www.sgmlight.com).
Removable diffusion filter
The G-4 Motorized Barndoors includes an external diffusion filter that is
installed in a slot located in the barndoors module, right after the front lens.
The filter can be used to improve the softness of the cut, generate a dreamy
haze, and enhance the skin tones whenever the fixture is used as a direct
front lighting.
The included diffusion filter (or diffusion gel) can easily be removed from the
slots (or mounted, if not attached).
The filter slots is a useful feature for other gel-based custom filters. To
attach a custom filter in the motorized barndoor module, simply cut the gel
in a round shape with Ø128mm, and insert it into the filter grooves.
Attaching/detaching the motorized barndoors
Swapping the front lens of the G-4 Wash or Wash-Beam for the motorized barndoors requires the replacement of both front lens and
back cover.
The replacement of the front lens is done in the same way as explained previously on page 19. With regard to the head back cover,
it must be replaced for a heavier one, in order to give the proper counterbalance between the front and the back of the fixture.
When purchased as an accessory, the Motorized Barndoors include full and detailed instructions on how to replace the front and
the head back cover. To get more information about how to install the motorized barndoors in a G-4 Series fixture, please contact

Motorized Barndoors closure
When operating the G-4 with motorized barndoors through DMX, be aware
that the blades are not allowed to close completely.
Keep therefore in mind that it is expected a tiny gap during the closure of the
barndoors, as shown in figure 20.
