Unpacking 

Immediately upon receipt, carefully unpack and inspect the  fixture to verify that all parts are 
present and have been received in good condition.  If any parts appear damaged from shipping 
or the shipping carton shows signs of mishandling,  notify the shipper immediately.  Retain 
carton and  all  packing material for inspection.  In the event that  the  merchandise  is to be 
returned, the original carton and packing must be used.  The customer will be billed for a new 
carton and packing if merchandise is received without the original carton and packing. 
 

Claims 

Physical damage must be reported to the  Freight Carrier or Shipping Company upon 
receipt of merchandise.  Damage incurred in shipping is the responsibility of the Freight 
Carrier or Shipping Company.  It is the customer’s  obligation in the event that 
merchandise is  received  damaged,  to notify the  Freight Carrier or Shipping Company 
immediately.  All other claims  not related to damage  incurred during shipping must be 
made to the Dealer or Distributor within 7 days of receiving merchandise.  

 

Returns 

Returned merchandise must be  in the original packing  with  a Return Merchandise 
Authorization number (RMA) clearly listed on the shipping label.    Items sent by Freight 
Collect or without a RMA number will be refused.   Call your sales person and request a 
RMA prior to shipping.  Be prepared to provide the model number, serial number and 
description of the nature of the return.  Shipping damage resulting from inadequate 
packaging is the customer’s responsibility.  Customer will be charged additional shipping 
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.

Troubleshooting 

Symptom 

Possible Cause / Solution 

Check for power on mains 

No Power 

Check main fuse and fuse holder 
Check data cables: connection and proper wiring  
Check Display settings 

Erratic / No response to DMX 

Check Start Address 
Check Start Address 
Check for overlapping addresses 
Check Menu settings 

Incorrectly responds to DMX 
(Diagnostic technique for DMX issues:  Set 
suspect fixture’s Start Address the same as a 
correctly functioning fixture. If both units then 
function correctly, issue is programming) 

Check Data cables (faults and proper wiring) 

 
 

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.
