FIXTURE ADDRESSING
Fixture addressing is performed at the rear of the fixture hanger assembly.
The fixture can be programmed to operate in DMX mode or FIXTURE mode
(for use with the hand controller). Because each LRX fixture requires sixteen
DMX channels for operation, FIXTURE mode is merely a convenient way of
skipping DMX channels in 16 channel increments, beginning with DMX
channel #001. Additionally, fixture mode provides power to a connected hand
controller, which is also designed to work in 16 channel increments.
DMX Connector pin out: (also see important note below)
Pin 1 = ground
Pin 2 = Data negative
Pin 3 = Data positive
Pin 4 = 12VDC negative
Pin 5 = 12 VDC positive
When the LRX fixture is in FIXTURE mode, pins 4 & 5 on the DMX IN
connector become energized to 12VDC to supply power to the hand controller.
No power is supplied to pins 4 & 5 when in DMX mode. Ensure that fixture is
in the correct mode prior to connecting DMX lines. Always connect the hand
controller to the fixture with the power off. Damage could result if attempting
to connect the hand controller to the LRX fixture while the power is on.
The mode (square icon) on the left is used to toggle between DMX mode and
FIXTURE mode. FIXTURE mode is designated by a capital ‘F’ in the left-most
digit, with the remaining two digits indicating the fixture number. E.g.
F01=fixture#1, etc. DMX mode is shown as a three digit number from 001 to
512. Once the mode is selected the fixture number or DMX address can be
increased or decreased using the up/down arrows on right side of the switch
assembly. When the correct FIXTURE/address has been selected, the store
(round icon) button second from the left is pressed and held (until the display
stops flashing) to store that address.
It is important to note that the LRX
fixture will not begin responding to a newly selected FIXTURE/DMX address
until it has been stored by pressing and holding the store (round icon) button.
If the display is flashing, this is a warning that the displayed FIXTURE/DMX
address does not match the address that fixture is currently responding to.
Saving the displayed address tells the fixture to begin listening and responding
to the new address. If the address is not stored within five seconds it will
return to the previous set

The LRX fixture always writes the last saved address and mode to non-volatile
memory, such that in the event of a power interruption, the fixture will power
up with the mode and address it was using before the power interrupt.
Pressing and holding the mode button will provide access to the hour meter.
Once in hour meter mode press the up icon to display bulb hours, indicated as
a scrolling number. It will show as a blank digit followed by three digits then a
decimal place and two more digits (i.e. _120.59). The bulb hours can be reset
by pressing and holding the store button until the meter zeros, about five
seconds.
To display fixture hours, press the down icon. Fixture hours will be displayed
as a scrolling number with an “F” prefix. This can’t be reset by the user.

DMX CHANNEL ALLOCATION
When using the LRX with a lighting console or other device that offers
discrete control over the DMX channels, they are used by the fixture as follows:
Where N= base channel of fixture. [LRX DMX address shown on display]:
N + (0-9) = motor control (depends on MODE)
N+10 = GEL fan ON/OFF (OFF<127<=ON)
N+11 = lamp control (unimplemented)
N+12 = motor control MODE: N+12<127 = BUMP MODE
N+12>=127 = FADER MODE
N+13 = reserved (future use)
N+14 = reserved (future use)
N+15 = reserved (future use)
If (MODE = BUMP): (n+12<128)
(N+0 > 127) = pan left
(N+1 > 127) = pan right
(N+2 > 127) = tilt up
(N+3 > 127) = tilt down
(N+4 > 127) = spot
(N+5 > 127) = flood
(N+6 > 127) = trolley left
(N+7 > 127) = trolley right
(N + 8, 9) = reserved (future use)
If (MODE=FADER): (n+12>=128)
(N+0 < 64) = pan left
(N+0 > 127) = pan right
(N+1 < 64) = tilt up
(N+1 > 127) = tilt down
(N+2 < 64) = spot
(N+2 > 127) = flood
(N+3 < 64) = trolley left
(N+3 > 127) = trolley right
(N+4 thru 9) = reserved (future use); each motor above is stopped
when the fader is in the middle of its range (DMX value 64-127)

FILTER INSTALLATION
LRX Lighting offers several high quality extreme temperature color
correction and diffusion filters. These filters will not burn or change
color and should be the first choice.
Custom colors can be produced to your specifications, please allow four
to eight weeks lead time.
LRX Lighting currently stocks:
¼ CTO
½ CTO
Full CTO
Steel Blue
Cyan 60
¼ Plus Green
½ White Diffusion
Full White Diffusion
Industry standard gel type color correction or diffusion filters should be
placed in the center slot with heat shield placed in the inside slot and the
outside slot. The heat shield in the outside slot helps to maintain the
column of cool air created by the filter fans.
If a color correction filter and a diffusion filter are both required the
color filter should be placed in the outside slot, the diffusion filter placed
in the center slot and heat shield in the inside slot. This provides the
longest filter life.
It has been reported to us that using two layers of ¼ CTO (with at least
one inch of air separation) to achieve ½ CTO is possible and might
provide better results than a single piece of ½ CTO.
Should the cooling fans on the gel frame holder become a sound problem
they can be shut off temporarily using the gel fan stop switches located
on the fixture hand controller or the appropriate DMX channel!
Note: filter life will be compromised, keep off time to a minimum.

LAMP INSTALLATION
A number of hazards exist during lamp installation please refer to
safety warnings on page two.
Follow lamp manufactures instructions regarding use and handling of their
product.
This fixture has more than one power supply. Disconnect all power supplies
before installation or removal of the lamps.
Allow lamps to cool before removing.
Prior to installing the lamp, check lamp contacts and wire ends for signs of
arcing or over-heating. If lamp contacts or wiring appear damaged remove
from service.
Ensure power supply matches lamp type, voltage and wattage.
The required lamp should be fully seated when installed and firmly locked
in place using the lamp lock tool supplied.
NOTE: the Metal halide lamp manufacturers suggest operating the lamp
with the lamp support rod up, as it produces a more stable arc.
Lamps should be wiped with 99% alcohol and clean paper towels or lint free
cloth after installation.
Clean, close and lock the lens.
Close and secure the lamp lock door.
Heat shield must always be used in front of the lamp. This provides
protection for the lens from rain and also helps to contain the glass
fragments in event of lamp breakage.
Ensure power supply matches lamp type and wattage. The use of dimmers
for tungsten lamps is strongly recommended.
Bringing tungsten lamps to full power without pre-warming the bulb and
fixture may break the U.V. lens.
Check gel fan and lamp fan for proper operation. When control power is
applied to the fixture, the lamp fan will start and run for ten minutes then
shut off, the gel fan will start and run for ten seconds then shut off. The
lamp and gel fan will restart when power is applied to the lamp and run for
ten minutes after power is removed from the lamp. It is very important to
leave control power to the lamp after it has been shut off to allow for fan
cooling of the lamp and housing. Overheating can damage the lamp and
internal components.
