charges to return products received in non original packing and or cartons.
Power
Do not apply power to the fixture until power source is verified.
For protection against electric shock, fixture must be connected to suitable earth ground.
Make sure fixture is disconnected from power mains before any service.
The mains voltage and frequency of this fixture is internally set. It can either be set to 120v or
230v AC 50/60Hz. The listed power rating is its average wattage under normal conditions. All
fixtures must be powered directly from a switched circuit. This fixture cannot be run on a
rheostat or dimmer circuit even if used solely for a 0% to 100% switching. Before applying
power to a fixture, check that the fixture’s input voltage matches the power source voltage.
Consult a qualified electrician if there are any concerns about proper connection to power.
Mounting
Always consult a qualified professional when rigging. Consider access for routine maintenance
when selecting a mounting position. This fixture may be mounted in any position provided there
is adequate room for movement and ventilation. Mount the fixture securely using a mounting
clamp and a safety cable. This fixture features dual yokes making it useful for floor standing at
different angles. Always keep cords out of the way, thus preventing any trip hazards. Secure all
cables properly. Do not mount where the fixture will be exposed to rain, high humidity, extreme
temperature changes or restricted ventilation. Do not obstruct any vents.

Setup and Operation Modes (LED Segment Display)
The following refers to the different modes that are available on this fixture via the LED
Segment Control Panel display. All functions are selectable from the display menu located at
the back of the fixture.
Control Panel Menu
Use the fixture’s Control Panel to access the Control Menu. The MENU Key puts the fixture in
the settings menu itself and also acts as a BACK key between options, UP/DOWN moves
through the menu options and allows the assignment of a value. The ENTER key is used to
enter that option and confirms the selection once the UP/DOWN is used to adjust the value.
When in edit, the display will Flash. Settings are stored and recalled on subsequent power
cycles. R, G, B, refers to Red, Green and Blue respectively. DMX and master/slave modes
require data cables to be connected between fixtures. Manual and some stand-alone modes do
not require data cables for independent use of the fixture.

Control Panel Menu Table
The following table describes the control panel’s menu options and settings. What is
displayed on the screen is marked in “quotations”. When this unit powers up, it will
display “SYON” for System Power On.
Note:
MODE will not show up in the control panel menu system. To enter the MODE
options, before applying power, you must hold down the MENU button for 6 seconds
while the unit is powering up. The factory default MODE is set to “04”, the 6 channel
DMX mode.
DMX-512 Control
Fixtures require a "Start Address" from 1 to 512, setting the first DMX channel containing data
for the fixture (see DMX Background). Before addressing fixtures, consult the manual of the
system’s DMX controller to select a desirable addressing scheme. Valid Start Addresses range
from 1 to 512. Fixtures requiring more than one channel for control will read subsequent
channels up to the total number of channels required. Since this fixture requires a maximum of
6 channels of DMX, if set to a Start Address of 7 it would use data from channels: 7 and 8, 9,
10, 11, 12. Choose a Start Address so the channels used do not overlap with other fixtures. In
some cases, it may be desirable to set two or more same type fixtures to the same Start
Address. In this case, the fixtures will be slaved together and respond to the same data.
Because all fixtures see the same data, fixtures may be set to any address without concern for
the order they are connected by the DMX cables.
Note:
For DMX to operate on this unit, all STANDALONE options must be set to Off.

DMX Data Connection
This fixture uses 3 pin XLR type connectors and shielded twisted pair cable approved for
EIA-422/EIA485 use. Fixtures are connected in Daisy Chain topography: Connection is
made from the controller to the DMX-IN of the first light, then from the DMX-OUT to the
DMX-IN of the next light and so on. Only one data source can be on a chain and no
branching is allowed. The physical order in which the fixtures are connected is not
important, use the most convenient.
Data Terminator
A Data Terminator can be connected to the DMX-OUT of the last fixture
to reduce the effects of signal noise; it is not required for all
installations. To make a Terminator, connect a 120-ohm ¼ watt resistor
across pin 2, Data Negative (S-) and pin 3, Data positive (S+). A
qualified technician can determine if a Data Terminator is needed.
Adapter
5-to-3 pin
Systems using 5 pin DMX interfaces can be accommodated by purchasing 3-to-5 pin
adapters or building adapter cables. Numbers designating each pin can be found on
connectors. Converting between the two XLR types is done in a pin-to-pin fashion.
Connect the shields to pin 1, then connect pin 2 to pin 2 and pin 3 to pin 3, regardless of
either connector’s gender or pin count. No connection is made to Pins 4 & 5.

DMX Start Address
To place the fixture in DMX mode, press the MENU key, then using the UP/DOWN keys
get to the Address Menu Option. Press ENTER and using the UP/DOWN buttons, set
the start address number for this particular unit in the DMX chain. Once selected, press
ENTER again to save your selection. More than one fixture may have the same start
address, but they will behave the same. Giving a unique start address that does not
overlap with any other units allows you to individually control that fixture’s features fully.
Never allow channels to overlap. You will need to select the number of channels you
wish the fixture to use first. Your choices are 3,4,5, or 6 channel modes. This will
determine the spacing of channels you will need to avoid overlapping of channels when
selecting your start addresses.
Example
Select Start Addresses for 4 fixtures each requiring 6 channels of DMX (6
channel mode).
For this example, start with the first unit set to the first possible Start Address =
1
. This fixture
occupies DMX channels 1 thru 6. The next DMX channel available for a Start Address is found
by adding the previous fixture’s Start Address to its channel requirement: 1+6=
7
. To maximize
channel usage, we will leave no empty channels between fixtures so the second Start Address
is set to DMX channel 7 and that fixture occupies channels 7 thru 12. The third fixture will be
addressed 7+6=
13
and occupy channels 13 thru 18. The last fixture is addressed 13+6=
19
and
will occupy channels 19 thru 24. Thus, 4 fixtures using 6 channels each have Start Addresses
of
1, 7, 13
and
19
and the next free channel in the system is 19+6=25.
DMX Channel Assignments
This fixture features 4 different DMX Channel modes. A 3, 4, 5, and 6 channel mode.
Using the 6 channel mode provides the most features, however it takes up the most
channels of DMX. The different channel assignments are shown below. We will provide
a full description of the values and functions of the 6 channel mode only. All other modes
of less channels, do the same functions described within the 6 channel mode.
Note that
the channel order maybe different for each of the mode.

Maintenance
Make sure fixture is cool and disconnected from power mains before any service.
Weekly operating hours and environmental conditions will establish how often the fixtures need
cleaning. Fixtures should be cleaned and inspected at least once a month to maintain optimum
performance. Accumulation of dust and fog residue increases heat build up, can lead to
malfunctions, overheating and reduction in maximum light output, reduced fixture life and over
all performance. Before conducting any maintenance, disconnect fixture from power mains.
1) Disconnect fixture from power mains.
2) Use a vacuum with a soft brush to remove dust collected on external vents and internal
components. If using an air compressor, use low pressures and extreme care to prevent
damaging any internal parts or effects.
4) Clean all optical elements when the fixture is cold. Use a soft lint free cotton cloth or tissue
and cleaner safe for plastics.
5) Inspect clamps and safety cables to ensure fixture is secure and safe.

DMX-512 Background
DMX-512 is a digital data transmission standard developed by the United States Institute for Theater Technology
(USITT). It is designed to enable control of lighting equipment. DMX deals solely with the formatting of data for
transmission and does not dictate how the data is created or used.
Under DMX, signals are transmitted in much the same way a computer modem transmits data. The Data, divided
into channels, is "Framed" using a start bit, high (1), eight data bits and finally, two stop bits, both high (1). DMX
uses no parity to check the integrity of the signal. Instead, DMX relies on the ultra low probability of an error
occurring in the same place when the data is resent. The rate at which data is sent is fixed at 250k bps, almost
four and a half times faster that a 56k modem. This speed allows all data on a DMX chain to be updated more
than 44 times every second.
The transmitted data follows a specific format. DMX allows for 512 channels each with eight data bits, giving each
channel the possibility of 256 values. When a data "Packet" is sent, all channels are transmitted one after another.
Even if the data on a specific channel has not been changed, it must be sent. In a packet, a "start code" of all
zeros is sent before the data to identify the signal as a Standard DMX transmission. This start code is transparent
to the user and is handled by the controller.
The physical signals are transmitted using a twisted pair of wires and a common shield, a configuration called
Balanced. The controller and all receiving equipment are connected using a “Daisy Chain" connection. The signal
is jumped from the controller to a piece of DMX equipment. From there, the signal is jumped to the next piece of
equipment and so on until the last piece of equipment is connected. No branches are allowed and the signal does
not come back to the controller. The final piece of equipment will have only one cable connection. As a result, all
equipment connected to the chain will see exactly the same signal whether it is first or last. When connecting
equipment, no particular attention needs to be paid to the order in which the equipment is connected. Depending
on the conditions and equipment, a line terminator may be required. If there is any question, in most
circumstances the addition of a terminator will not degrade the signal. To make a terminator, attach a 120-ohm
resistor between the Signal Data Negative and Signal Data Positive pins of a connector in the last piece of
equipment in the chain.
The DMX Standard uses 5 pin XLR connectors. However, it is common to see
fixtures with 3 pin XLR connectors as these types of balanced or “Lo-Z” cables
are common in the audio industry. In either case, pin numbers are the same
and carry the same signals.
