BL-48 DMX Ultraviolet Illuminator

The BL-48 Ultraviolet Illuminator is a state of the art lighting instrument based on an array of 48

Ultraviolet LED's and a computer micro-controller. This unit permits ultraviolet effects to be faded

or strobed under DMX control. These effects cannot be created with other types of UV

illumination. The LED UV devices do not require replacement, produce little or no heat, and are

available in a range of dispersion angles and UV or near-UV wavelengths. From one to four

channels of DMX-512 data controls UV intensity, strobe rate, or other parameters as determined by

the LED configuration, and the settings of internal mode jumpers. The unit may also be operated in

manual mode without DMX as a stand-alone fixture with preset intensity and strobe timing if

desired. Illuminators may be controlled by any DMX lighting system for professional displays, or

may be set up for independent operation at a preset intensity or strobe rate in stand-alone UV

lighting applications.

A range of UV LED options are now available for installation in the unit. For replacing existing

fluorescent or incandescent UV light sources, 395 nanometer UV LED's may be installed to

duplicate the deep blue-violet output common to those fixtures. For pure ultraviolet displays, 385

nanometer LEDs, which produce very little visible light may be selected. UV LED sources of

different types, or with different dispersion angles may be installed in the same fixture, with each

LED type then controlled independently through DMX, providing unprecedented flexibility in an

ultraviolet fixture. All LED emissions are long wavelength UV-A light, which is not considered a

skin or an eye hazard under normal conditions.

LED RADIATION

CLASS 1M LED PRODUCT

Controls and Connections

The rear panel of the unit includes a power input jack for a UL approved Class II 24 volt DC power

source, a red LED power indicator, and three rotary selector switches to choose the base DMX

address for the device. A slide switch to the left of the address switches can be set to provide a

resistive termination to the DMX data lines if the unit is the last device in the DMX data string. A

green LED DMX sync indicator is located to the left of the termination switch to provide a positive

indication of DMX data reception, and to confirm the mode setting of the unit on power up. The

DMX input and output connections are located on the lower half of the unit, to the left of the power

input socket.

Control Panel Connections

CAUTION

Connection of the unit to AC power sources, or to alternative power supplies other than the

universal input DC power pack provided with the unit may result in damage to the unit. Do

not attempt to operate the unit if you are unsure of the rating of the AC power source, or of

the voltage and polarity of any alternative DC power supply. Connections made to the DMX

Input and Output terminals must conform to the US-ITT DMX-512 standard to insure proper

operation of the unit. Any damage resulting from accidental application of incorrect power

supply or DMX signal voltages will not be covered by the system warranty.

Basic Operation

The unit may be operated from any AC power source from 100 to 240 volts AC, 50 or 60 Hz. The

universal voltage AC adapter provided with the unit will convert any AC power source within this

range to the 24 volts DC at .5 ampere maximum required by the unit. The unit is ready for

operation once the AC adapter is plugged into a suitable power source, and the DC output power

from the adapter is applied to the unit.

The LED power indicator on the rear panel will illuminate in green when the unit is on. When

power is first applied, the green DMX Sync indicator will blink from 1 to 4 times to indicate which

internal mode setting is selected. The internal processor will then read the address information

selected on the three DMX address switches, and will respond to appropriate DMX commands, or

to manual operation instructions as established by those switch settings and the internal mode

selected. After the start sequence is complete, the DMX Sync indicator will illuminate steadily in

green when valid DMX data is being received, and will not illuminate, or will flash intermittantly if

DMX data is absent or unstable.

Default Settings

Unless otherwise specified, all units are shipped with factory default mode and DMX address

settings. The default factory mode is Mode 1, single channel mode, where one DMX channel will

control the intensity of the UV emission from the unit. The default DMX address setting is to a

base address of 001.

The default setting of Mode 1 will allow access to the manual mode functions, which allow the unit

to be operated or evaluated without the need for a DMX signal source. Manual mode operation is

described more completely in a later section of this manual.

Base DMX Address Settings

The three rotary address switches are set to select the base DMX address for the unit. The address

switches should be preset to the desired base DMX address before the unit is powered up, as the

address settings are read during the power up sequence. If it is necessary to change the DMX

address for the unit, the address settings may be changed at any time, but the unit will not read or

respond to the new channel assignment until power is removed, and restored once again.

DMX Channel Useage and Allocation

Once the base DMX address is read, the unit will respond to changes in the DMX data for the

selected channel or channels depending upon the selected operational mode. From 1 to 4 DMX data

channels may be occupied by each unit depending on the internal mode setting. For all multi-

channel modes, the additional DMX channels occupied are sequentially higher than the base DMX

address selected by the selector switches. For example, a unit operating in Mode 2, which uses two

DMX channels, and set to a base DMX address of 100 would occupy and respond to information on

DMX channels 100 and 101. A unit set to Mode 4, which uses four DMX channels, and a base

DMX address of 200 would occupy and respond to information on DMX channels 200, 201, 202,

and 203.

DMX Data Connection

Once the base DMX address setting is complete, the unit may be connected to a DMX data source.

The green “Sync” indicator will illuminate steadily if valid DMX data is being received by the unit.

In normal operation, the unit will respond to changes in the DMX data for the selected channel or

channels by increasing or decreasing the intensity of each LED emitter, or varying the motor speed

in direct response to the DMX channel control levels. When normal DMX data is being received,

the unit will retain the last valid data for about 5 seconds after the DMX data is removed. This data

retention allows the unit to tolerate minor interruptions in the DMX data stream caused by poor

connections or brief “dropouts”. After this interval, the unit will default to the normal “no DMX

data” state, with all output channels inactive. Normal operation will resume immediately when the

normal data stream is restored.

DMX Troubleshooting

If the “Sync” indicator is not steadily illuminated when DMX data is connected, then there is either

a problem with the DMX data or cables, or an internal problem with the unit. If the unit does not

operate, and the “Sync” indicator flashes at a regular interval, the DMX address is set to an invalid

range, either to zero, or to a number higher than 512, which is the highest base address setting

which will allow control of the fixture in single channel mode. If the “Sync” indicator is erratic,

then the DMX data connection is either intermittent due to a poor electrical connection, or the DMX

data is dropping out, which can be caused by poor connections, poor quality cables, long data runs,

or poor signal quality in general. Test the unit with different cables, or in a different location closer

to the DMX data source to determine what or where the problem is.

Operational Mode Settings

The BL-48 unit may be operated in any one of four modes as selected by internal programming

jumpers. Power must be removed from the unit before opening the cover to change the mode

jumper settings. Once the unit is inactive, the upper housing of the unit may be opened by

removing the four screws along the sides. Once the screws are removed, the top cover may be

opened to gain access to the internal circuit board with the jumpers.

Operational Modes

The mode selection corresponds with the number of consecutive DMX channels used in each mode,

beginning from the base DMX address selected by the address switches. The DMX channel

function and operation of the unit in each mode is listed in the following table.

Mode Selection

The Mode Select jumpers are J7 and J8 located near the right edge of the main circuit board

between the large regulator IC and the power input socket. Move the shorting jumpers as indicated

in the diagram below to change the operating mode. Refer to the parts layout drawing which

appears later in this manual for further illustrations of the jumper location if necessary.

Once the desired mode settings are in place, the top cover of the unit should be replaced, and the

screws reinstalled before applying power to the unit. Operation of the unit in the desired mode may

be confirmed by observing the DMX Sync indicator lamp, which will blink from 1 to 4 times when

power is first applied to the unit to indicate which mode is currently selected.

Mode 1 Operation: Master Intensity on 1 DMX Channel

Mode 1 is the simplest operational mode, using only a single DMX channel, corresponding to the

base address selected by the three address switches. The data on that DMX channel will control the

intensity of the output from the unit, with a zero level producing no output, and a maximum level of

255 producing maximum output from the unit. Manual mode operation, as described later in this

document, is only available when the unit is set to Mode 1.

Mode 2 Operation: Master Intensity plus Strobe on 2 DMX Channels

Mode 2 allows control of both Intensity and Strobe rate, and uses two DMX channels beginning

with the base address selected by the address switches. The data on the first DMX channel will

control the intensity of the output from the unit, with a zero level producing no output, and a

maximum level of 255 producing maximum output from the unit. The data level on the second

DMX channel will control the flash or strobe rate of the unit, with a zero level producing a one

second flash every other second, with a maximum flash rate of around 30 flashes per second at a

data level of approximately 245. Data levels from 245 to the maximum of 255 will result in

continuous operation. Manual operation, as described later, is not available in Mode 2.

Mode 3 Operation: 3 Bank Intensity on 3 DMX Channels

Mode 3 allows individual control of Intensity for each of the three banks of 16 LED devices

installed in the unit. This mode uses three DMX channels beginning with the base address selected

by the address switches. The data on the first DMX channel will control the intensity of the LED

devices in Bank 1, with a zero level producing no output, and a maximum level of 255 producing

maximum output. The data levels on the second and third DMX channels will control the output of

the LED devices in Banks 2 and 3 in a similar manner. This mode is most commonly used with a

mixture of LED dispersions, wavelengths, or with banks of UV and White LED’s. Manual

operation, as described later, is not available in Mode 3.

Mode 4 Operation: Master Intensity plus 3 Bank Intensity on 4 DMX Channels

Mode 4 allows individual control of Intensity for each of the three banks of LED devices installed

in the unit, plus a master level control. This mode uses four DMX channels beginning with the base

address selected by the address switches. The data on the first DMX channel will control the

intensity of all LED devices in all banks, with a zero level producing no output, and a maximum

level of 255 producing maximum output, up to the levels set by the individual bank controls. The

data levels on the second, third, and fourth DMX channels will control the output of the LED

devices in Banks 1, 2, and 3 in a similar manner. This mode is most commonly used with a mixture

of LED dispersions, wavelengths, or with mixed banks of UV and White LED’s. Manual

operation, as described later, is not available in Mode 4.

Manual Mode Displays

The manual mode displays are intended to provide the unit with a reasonable capability for

demonstrating the properties of the unit, and are also useful for testing This capability may also be

sufficient to complete simple effect installations where the cost or complexity of DMX controls are

not necessary, but the benefits of a compact and very low maintenance UV source would be

attractive. For those installations where the manual mode capacity of the unit are not precise or

flexible enough, the use of the DMX control features should allow the unit to perform exactly as

required.

Manual Mode Operation

Manual Mode operation is available only when the internal Mode jumpers in the unit are set to

Mode 1, and the DMX address switches on the unit are set to addresses 600 and higher, which are

beyond the normal range of the DMX-512 standard of 512 channels. The address switch settings in

the range of from 600 to 699 and from 700 to 799 correspond to distinct manual mode functions as

described in the following table:

Manual Mode Minimum Maximum Minimum Effect Maximum Effect

Intensity 600 699 0% 100%

Strobe 700 799 .5 Hz. 30 Hz.

Manual Display Programming

Operation of the unit in Manual Mode is controlled by the settings of the DMX address switches.

The output of the unit may be adjusted using the address switch settings to obtain a wide range of

intensity levels and strobe rates. Once established, manual mode settings are retained when power

is removed from the unit, and will be restored when power is reapplied provided that no changes are

made to the address switch settings. The manual settings may be altered by adjusting the settings at

any time. The unit will resume normal DMX operations when the address switches are set to a

value of 512 or less.

Manual Mode Intensity Control

When the base address switches are set to a range of 600 to 699 when power is first applied to the

unit, the unit will produce UV output from 0 to 100 percent intensity, with no output at a setting of

600, and maximum output at a setting of 699. Output within this range is continuous, and is not

affected by any other setting.

Manual Mode Strobe Rate Control

When the base address switches are set to a range of 700 to 799 when power is first applied to the

unit, the unit will produce strobed UV output at 100 percent intensity, with a minimum rate of .1

Hz. (5 seconds on, 5 seconds off) at a setting of 700, and a maximum rate of approximately 30 Hz.

at a setting of 799. Control settings above this level will result in continuous output.

Circuit Description

The BL-48 Illuminator circuitry is most easily described as six sections, which are the power

supply, the microcontroller, the DMX interface section, the address and mode selection section, the

DAC or PWM output section, and the LED drivers and array. The microcontroller is the key

element in the circuit, as the data ports on the device are assigned to all key circuit and interface

functions. The microcontroller responds to settings of the mode and address control switches, reads

incoming DMX data with the proper address information, and generates the output data which

controls the LED drivers. Each circuit section is explained in further detail below.

Circuit Block Diagram

Theory of Operation

Upon power up, the microcontroller sets the configuration of all internal registers and variables

according to firmware programming, then reads the settings of the internal mode jumpers to

determine the general display configuration. Once these settings are established, the controller then

reads the settings of the DMX address switches, and goes into either a manual display mode if the

address settings are 600 or higher, or a DMX controlled mode if the address settings are in the range

of from 1 to 512. If no DMX data is available, the unit enters a “Standby” state, prepared to

respond to valid DMX data input. The microcontroller monitors the DMX control lines, and awaits

a signal to initiate a display. Upon receipt of a suitable signals, the controller then sets the intensity

or other display variables to the to the required levels established by the DMX data. The display is

maintained at the last valid level for a preset interval of about 5 seconds if DMX data is lost or

interrupted. If no DMX data is received after this interval, the controller then returns to the normal

standby state, and continues to monitor the inputs for additional DMX control signals.

Power Supply.

The illuminator is powered by an external DC power pack, or wall type transformer at a voltage of

24 volts DC, and a current of 350 milliamperes minimum. Suitable power sources are available

with approvals from UL and other electrical safety agencies, and in several input voltage ranges.

Power is applied to the illuminator unit through the 2.1 millimeter center positive DC plug J1 on the

rear panel of the unit. Power applied to unit passes through a self resetting current limiter, a

polarity protection diode, and a transient surge absorber before it is applied to the 5 volt regulator

IC Q3, which reduces the input voltage to the 5 volt level required by the microprocessor and other

logic circuitry. The higher unregulated voltage from the external power supply is applied to the

power / sync indicator LED, and to the LED array, as the extra voltage is needed to drive the series

connected ultraviolet LED’s used in the array. A separate 5 volt DC to DC converter is used to

power the DMX input section. This separate power supply allows the electrical isolation of the

DMX input and output lines from the remaining circuits in the unit.

Microcontroller

The illuminator is based on an Atmel ATMEGA8 microcontroller U2, which operates all critical

illuminator functions. The microcontroller uses an external 16 megahertz clock oscillator X1 for

timing control, and is internally protected against transient voltage conditions. The processor

operates from permanent firmware EPROM programming which controls all functions of the

illuminator. This programming is performed during manufacturing, and may not be re-written by

the user. The microcontroller has three 8 bit input / output ports, which may be programmed as

needed for each particular application. These ports are commonly identified by letter designations,

B, C, and D. In the BL-48 illuminator, the B port is used output data to the LED driver circuitry,

and for device programming, the C port is used for device programming and to read DMX address

settings, and the D port is to read address and mode settings, and for DMX input and sync

indication.

DMX Interface Circuits

The DMX data stream is applied to the BL-48 unit on the 5 pin male XLR connector J2, and passed

directly through to the 5 pin female XLR connector J3. DMX data is buffered by the IC U5, and the

opto-isolator OP1 before it is applied to the RXD terminal of the microcontroller on pin 30 (PD0).

The microcontroller processes the incoming DMX data, and indicates proper data reception by

outputting a sync indication on pin 11 (PD7) to the LED driver Q1 and the power / sync indicator

LED

Address / Mode Selection Circuit

The three DMX address switches S1,2 and 3 are connected directly to microcontroller inputs on

pins 23 through 28, (PC0-5), on pins 31,32, 1, and 2 (PD1-4), and on pins 19 and 22 (ADC6,7).

These pins to provide DMX address information to the microcontroller. Other inputs on pins 9 and

10 (PD5,6) are used to select the general operating mode of the unit. The remaining input

connections on pins 14-17, and 29 (PB2-5, PC6) are used for device programming.
