V1.21 September 2007 iPAK/iPRO Dimmer Operator Manual

1.0 DESCRIPTION

The LSC iPAK and iPRO series of dimmers are high quality, high performance digital dimmers
designed for wall mounting, truss or hand rail hanging, 19” rack mounting or free standing
applications. Both dimmers share the same construction technique, however, the iPRO offers
extra features above that of the iPAK.

All dimmers are constructed utilising a hinged Dimmer Chassis that is connected to an
Installation Frame. The Dimmer Chassis houses the electronics, dimmer module cooling fan and
in the non-hard-wired versions, houses the DMX512 in and thru and output load connectors. The
Installation Frame houses the mounting locations for wall fixing and 19” rack mounting, the input
power terminals and in the case of the hard-wired versions, all the output screw terminals and
the DMX512 input and thru terminals.

Built around a custom aluminium extruded heatsink that provides central mounting for all major
internal components, the overall design concept provides a very efficient air flow path allowing
the dimmers to run with a 100% duty cycle. Advancements in electronic componentry, inductor
performance and heat dissipation techniques have resulted in a compact, yet well laid-out design
that is ideal for transporting and servicing. Great emphasis has been placed on component
minimisation, thus resulting in higher reliability.

Each channel is protected by a fast acting Miniature Circuit Breaker (MCB) with LSC’s
proprietary Current Control Technology© to minimise nuisance tripping of the MCBs when high
inrush currents are suddenly applied. The added benefit is that lamp filaments are also protected
from this shock, thus extending lamp life.

High quality toroidal inductors and filtering circuits minimise the possible interference to other
electronic equipment by reducing the harmonic waves produced by phase angled control of the
power mains. A low noise fan is used to circulate cool air over the dimming circuitry and the
iPRO has the added feature of variable fan speed control based on dimmer temperature. That is,
the higher the temperature of the dimmer, the faster the fan will run.

Ease of operation is a key element of the iPAK and iPRO dimmers. The clever use of
pushbuttons and easy to read displays allow the user to quickly set the DMX512 address, to
drive individual channels at varying levels, to create a 12 channel scene that can be stored in
non-volatile memory and to set a choice of up to six different fade curves for each dimmer
channel (iPRO only).

Ongoing software upgrades are made easy with LSC’s CodeLINK software up-load option.
CodeLINK is a program that permits dimmer software upgrades from a PC style computer.
Upgrades are available from LSC via the Website (www.lsclighting.com.au) or via e-mail
([e-mail]). Software can then be transferred into the iPAK and iPRO
dimmers via a serial cable link from the PC computer into the DMX512 input connector on the
dimmer. Refer to section 5.3 for more detailed instructions.

The iPAK and iPRO’s compact design and rugged construction, make them ideal for schools,
churches, convention and exhibition centres, the Broadcast Industry and generally anywhere
good quality entertainment dimming products are needed.

3.0 GETTING CONNECTED

3.1 Input Supply

The iPAK dimmer can accept up to a 40 Amp 3 phase, neutral and earth input supply,
whereas the iPRO dimmer can accept up to a 52 Amp 3 phase, neutral and earth input
supply. Connecting to a lesser value supply, such as a 32 Amp or a 40 Amps per
phase respectively, will limit the dimmers overall output accordingly.

There are a number of possible entry points in
the Installation Frame to connect the incoming
three phase supply. For hard-wired installations,
there are two large knock-out panels located on
the upper left hand region. These knock-out
panels can easily be removed using heavy-duty
cutters and allows wiring to enter and exit the
dimmer via cable ducting on top of the installation
frame, or direct through a wall cavity at the rear of
the frame. For portable or installation situations
where a flexible three phase tail and plug are
required, a 32mm diameter hole exists on the
upper left side panel of the Installation Frame. A
hole plug is supplied to cover this hole when the
product is shipped. By removing this plug, a
correct size metal or plastic strain-relief gland can
be fitted to secure the three phase tail to the
chassis. Termination of the three phase wiring to
the internal terminal blocks, should be
undertaken by a qualified electrician.

Connection is Three Phase Star, however other
versions such as single phase(s), two phase and
Three Phase Delta wiring are available upon
request from the factory. Contact LSC Lighting
Systems or your nearest Distributor for further
information.

It is imperative that the supply Circuit Breakers to
the dimmers are rated equal, if not lower than the
dimmer’s phase capacity. Correct connection of
the Neutral must be maintained, otherwise
serious damage could occur to the dimmer or
loads connected to the dimmer.

Phase failure is indicated on the front panel by
individual LED’s for each phase. Refer section

4.6 for more detail.

LSC Lighting Systems (Aust) Pty Ltd 5

V1.21 September 2007 iPAK/iPRO Dimmer Operator Manual

3.2 Control Input

The dimmers are designed primarily to accept control signals conforming to the
DMX512/1990 protocol. Connection is made through the DMX512 Input connector
located on the front panel. A Thru connector located next to the Input, allows the
connection of the dimmer to other DMX512 devices downstream. The Thru connection
is passive and allows for the pass through of the DMX512 signal, even if there is no
power to the dimmer.

The IPRO/T model has all DMX512 connections internally
wired to a 4mm² pressure clamp screw terminal connector.
However the LINK connector on the front panel remains as
this still allows for software upgrades as detailed in Section

5.2.
LED’s on the front control panel indicate the condition of

the incoming DMX data. Valid data is indicated with a
Green “DMX data” LED. Bad data is indicated with a Red
“DMX error” LED.

It is advisable that if this dimmer is the last DMX512 device
in a long data stream, then connect a “Terminator” in the
“Thru” connector to stop any possibility of reflections on the
DMX512 Network. The “Terminator” can be a mating plug
with a 120 Ohm resistor soldered between pins 2 and 3.

3.3 Load Connection

Internal

DMX

connector

The iPAK/A dimmer is only available as an Australian version, providing twelve 10
Amp HPM No. 38 Sockets, whereas the iPRO dimmers offer a wide selection of output
load connectors to suit the many applications and countries that these dimmers are
sold to. For Australian versions, the iPRO/A is supplied with twelve 15 Amp HPM No.
38 Sockets, whereby the iPRO/6A is supplied with six 25 Amp HPM No. 38 Sockets to
suit the higher current capacity per circuit. For European versions, twelve Shuko 2 x 16
Amp Sockets (iPRO/SE) or 24 x 15 Amp UK sockets can be fitted (iPRO/UK).

The hard-wired version of the iPRO is
supplied with three detachable load
connectors. Each connector contains
four dimming circuits where each circuit
consists of three (Active, Neutral, Earth)
4mm² pressure pad screw terminals.

The iPAK is a soft-fired dimmer, and as
such, is suitable for most resistive type
loads. The iPRO is a hard-fired dimmer
meaning it is very suitable for resistive
loads as well as most inductive loads
such as fans, motors, ballasts and dimmable fluorescent tubes. Care should be taken
when driving inductive loads as not all of these types of loads can be dimmed. If you
are in doubt to the dimmers suitability for the intended application, please consult LSC
Lighting Systems or your nearest Distributor for further information.

Under all circumstances during the operation of the dimmer, it is highly advisable not to connect or disconnect the
load while live, to prevent potential damage to the dimmer, the load connectors or to the load itself.

V1.21 September 2007 iPAK/iPRO Dimmer Operator Manual

3.4 Overload Protection

Each dimmer is fitted with twelve (six) fast acting Miniature Circuit Breakers (MCB’s),
one for every output channel. Under normal operating conditions the MCB’s pass the
rated current and will only trip when there is an overload through the dimmer circuit.
Likewise, if there is a short circuit on the load or faulty wiring on the load side, the MCB
will trip to protect the internal components of the dimmer.

The MCB’s are located on the front panel of the dimmer allowing quick visual access
to which channel has a fault or overload condition. Dimmer channels can be manually
disabled by switching off the MCB for that particular channel. This is particularly useful
for those occasions where a genuine fault has occurred.

3.5 Installing the Dimmer

The iPAK and iPRO dimmers are one of the most versatile dimmers on the market,
offering no less than four different installation options. The dimmers can be floor or
bench mounted; hung from lighting bars or handrails; mounted to walls; or fastened to
19” rack systems.

The angled bottom of the Installation Frame allows
the dimmer to sit angled on a floor, bench or table
top. This is ideal for portable situations where the
dimmer can be placed in awkward positions to
allow easy interconnection to the load circuits. In
this scenario we recommend great care is taken so
power and data leads and the connecting load
circuits do not create an operational hazard to
others.

On the top of the Dimmer Chassis, three 12mm
holes are provided for the attachment of two 2”
Hook (C) clamps and a safety chain. The holes
are positioned to allow the centre of gravity of
the dimmer to be directly underneath. To fit the
Hook clamps, the two screws holding the
Dimmer Chassis to the Installation Frame need
to be removed and the Dimmer Chassis hinged
forward. From the inside fit two bolts to fasten
the Hook clamps to the top of the Dimmer
Chassis. There are two holes, one on the top
left and one on the upper side left of the
Chassis, that allow the connection of a rated
safety chain.

The rear panel of the dimmer has provisions for
mounting to walls and other upright structures. In
this situation care must be taken not to mount the
dimmer close to other dimmers or objects, such
that the side air vents of the dimmer may be
impeded. Allow a minimum of 150mm clearance on
either side of the dimmer. The eight holes on the
outer side of the rear chassis allows the dimmer to
be fastened to a 19” rack frame.

4.0 DIMMER OPERATION

4.1 Front Panel Controls

Good product design generally relates to good user interface and providing a well laid out,
concise, easy-to-read control panel is the key. The design of the iPAK and iPRO dimmers
concentrated very heavily on this principle and the end result has produced an easy to use
control panel that allows very quick access to all functions and indicators that show the exact
status of the dimmers.

Following is a brief explanation of the switches and displays.

4.2 Setting the DMX512 Address

The dimmer is designed to be controlled by an external DMX512 transmitting device. The
DMX512 protocol allows for the high speed transmission of 512 channels of digital data and
allows for up to 32 devices to be connected to each DMX512 stream. To enable each device to
receive its own relevant information off this DMX512 stream, a DMX512 Start Address is
allocated to each device. In other products, this start address is selectable on the device by
either switches or thumbwheels and the number displayed corresponds to the first channel of the
device.

If the iPAK and iPRO twelve channel dimmers have the start address set for “001”, then the
dimmers will respond to the first twelve channels of information on the DMX512 stream. Likewise
if the start address is set for “025”, then the dimmers will respond to channels 25 to 36 on the
DMX512 stream. If two or more devices have the same address setting, these devices will
respond to exactly the same data. Care must be taken when setting up all equipment on the
same DMX512 network. All data on the DMX512 stream can pass through the dimmer and onto
the next device, when the thru connector is utilised. Similarly the six channel iPRO’s respond in
the same way, except they only use the six channels of information on the DMX512 stream that
pertains to them as set by the address number.

When the dimmer is powered up for the first time, it will automatically be in the DMX512 Address
mode and display channel 1 as its starting address. The user can then set the desired start
address by pressing the increment(∧) or decrement(∨) Scroll Buttons. If you decrement from
channel 1, the next setting will be 512. To scroll quickly to your desired start address, press and
hold the increment or decrement button. The display will then speed up and scroll through the
channel numbers.

To increase the start address in banks (groups of 12 for 12 channel dimmers and groups of 6 for
6 channel dimmers.), press the button quickly once and then press and hold. If the dimmer start
address is currently at “1”, then to select the next bank (start address number 13 (7) ), press the
increment button quickly once and then press again and hold. The display will then indicate “”b­2”(Bank number 2) and then it will display channel “13” (“7”). Repeat this step to move to the next
bank. To move the start address backwards in groups of 12 (6), repeat the instructions above
using the decrement button.

Once the DMX512 Address has been set, this will be stored in the dimmer’s memory. (Note: The

DMX512 address will only be committed to memory approximately 5 seconds after the last
address change.) If the dimmer is powered down and then powered back up, the dimmer will

resume at its last known DMX512 setting.
The Data Indicators show the exact status of the DMX512 signal as it relates to that particular

dimmer. When the DMX512 connector is plugged into the dimmer and signal is being received,
the green data LED will glow to indicate good data being received by the dimmer. If bad data is
being received, the red LED will glow. In some instances, the green and red LEDs will
intermittently come on and off. This indicates that the data being received is “dirty”, in that it is
sometimes valid and then becomes invalid.

If the DMX512 input connector is fitted and no LEDs are glowing, this can indicate two things.
The first is that the transmitting device has ceased transmitting and the second could mean that
the signal is no longer reaching the dimmer due to a fault up line. In both cases, the dimmers will
sense the loss of signal and then hold the last known DMX512 state that it received, until the
DMX512 data stream is restored or until the dimmer is powered down.

V1.21 September 2007 iPAK/iPRO Dimmer Operator Manual

4.3 Test Function

4.3.1 Driving Channels

A very useful feature found on most LSC dimmers is the ability to individually or group select
channels and drive the outputs from 0 to 100%, without a control device being connected. This is
particularly useful when doing onstage focussing, pre-heating of lamps or general dimmer
testing.

To activate, press the Mode Select Switch until the “Channel” LED illuminates. Press the Scroll
Buttons until the desired channel is reached. The corresponding channel number will be
displayed in the Status Display. At this stage all channels can be activated by pressing the
increment Scroll Button once quickly and then pressing and holding until “ALL” is displayed. The
“ALL” mode will stay active until either the increment or decrement Scroll Button is pressed.
Press the Mode Select Switch to move the function to “% Drive”. Again use the Scroll Buttons to
adjust the channel(s) output level. The output is displayed as a percentage of the total output,
that is “60” is 60% of the output. To adjust another channel, repeat this process by pressing the
Mode Select Switch to “Channel” and selecting the next channel. If loads are not to be driven
during this stage, they can be isolated by switching the channel MCB off.

The Scroll Buttons can be used to scroll quickly through the “Channel” and “% Drive” levels by
either of two methods:
i) Pressing and holding down the increment or decrement button will move the channel

number or output level by a rate that begins slow and then speeds up.

ii) Pressing the increment or decrement button once quickly and then pressing and holding

will snap the output level to either its maximum or minimum setting.

4.3.2 Chase Test Mode

Another useful test feature, is the ability to set the dimmer to sequentially fade through all its
channels. In essence, it appears as a single channel chase that fades each channel up and then
down. To activate this, select “Channel” on the Mode Selection Switch and then press both Scroll
Buttons for less than two seconds and release. The Status Display will show the last known
channel number entry and will then automatically scroll through the channels. The “Channel”
LED will pulse to indicate that the dimmer is in this chase test mode. The output level will default
to zero, however pressing the Mode Selection Switch will activate the ”% Drive” mode. Use the
Scroll Buttons to adjust and set the output level. Press either one of the Scroll Buttons to stop the
chase and subsequent presses will increment or decrement the channels. To resume the chase,
press both Scroll Buttons quickly.

4.3.3 Pre-Heat

Prior to a show’s performance, it is highly recommended to pre-heat the filaments in the fixtures
to prevent sudden thermal shock to the lamp, thus reducing the possibility of damage or
shortened lamp life. To activate the pre-heat function select “ALL” on “Channel” mode and then
drive the outputs to around 8 to 10%. This level should allow sufficient current through the
filament to glow slightly, but not produce any noticeable light output on the stage. A time span of
10 to 15 minutes should be enough to warm most types of theatrical lamps. To set a permanent
pre-heat, refer to section 4.4 Scene Storage and create a scene that will activated when the
dimmer is powered up.

Two things to consider while in the Test Function mode. If a DMX512 controller is connected to
the dimmer and begins to transmit, the incoming signal will work on a HTP (Highest Takes
Precedence) basis with anything that is set on the dimmer’s control panel. That is, if the dimmer
is currently set for pre-heat at 10% and the incoming signal has channel data greater than 10%,
then the dimmer will output the higher value. Likewise, if the incoming signal drops to 0%, then
the output will be at 10%, the pre-heat level. Secondly, if power to the dimmer drops out and is
then restored, the dimmer will automatically start at the DMX512 Address mode. All previous
settings will be lost.

LSC Lighting Systems (Aust) Pty Ltd 10

V1.21 September 2007 iPAK/iPRO Dimmer Operator Manual

4.4 Scene Storage

This function provides the capability to create a single 12 (6) channel scene using the front panel
controls and then store this into the dimmer’s memory for recall at any point while the dimmer is
switched on.

To activate the Scene function, press and hold the Mode Select Switch until the “Scene” LED
illuminates. The LED will now begin to pulse off and on, indicating the Scene function is
activated. The “Channel” LED is also activated (on) at this time indicating the dimmer is now
ready to start creating the scene. Using the Mode Select Switch allows the operator to toggle
between the “Channel” and “% Drive” modes, whilst the Scroll Buttons allow the selection of the
channel number and output level respectively. Once a channel level is set, repeat the above
steps to move to the next channel, thus creating the desired scene (group of channels).

The scene is automatically stored in the dimmer’s non-volatile memory, meaning that any
changes to the scene will over write the existing stored memory. Similarly any new scenes
created will automatically write over the previous stored scene. (Note: The scene is committed to

memory approximately 5 seconds after the last change.)

If power is switched off or disconnected while the dimmer is in Scene mode, when power is
restored, the dimmer will resume in its last known state – “Scene”. Any stored scenes are also
retained in memory when power is switched off and can be accessed when power is restored.

To exit Scene mode, press and hold the Mode Select Switch until the “Scene” LED goes out.

4.5 Curve Selection

This function is only available on the iPRO range of dimmers and allows for an individual fade
curve selection on any or all dimmer channels. Six different curves are available and are
displayed as follows on the Status Display.

S LAW displayed as “C1”
SQUARE LAW displayed as “C2”
CUBE LAW displayed as “C3”
QUAD LAW displayed as “C4”
120V CURVE displayed as “120”
NON-DIM SWITCHING displayed as “non”

The S, SQUARE, CUBE and QUAD Laws are variations on the dimmers fade response to suit
performance characteristics of various types of lamps. The 120V curve is primarily for use with
120 Volt Par 64 lanterns and equates to a standard “S Law” curve for 120 Volt lamps. If this
curve is selected take particular note that only 120 Volt lamps can be connected, up to a
maximum of 10 Amps per dimmer channel. LSC Lighting Systems (Aust) Pty. Ltd. takes no

responsibility for any possible damage to lamps operated in this mode.

The NON-DIM curve provides the facility for channels to operate as electrical switches. This is
ideal for motor control, smoke machines and other special effects. When activated the dimmer
channel will switch on (100% output) when the fader level reaches 60% and switches off (0%
output) when the controlling fader level drops to 40%.

To activate the Curve function, double click and hold the Mode Selection Switch until the “Curve”
LED illuminates and begins to pulse off and on. The word “Cur” will be visible in the Status
display, indicating the Curve function is activated. Press the Mode Selection Switch again. The
“Curve” LED will continue to pulse and the “Channel” LED will be illuminated. Using the Scroll
Buttons, increment or decrement to move to the channel required. Press the Mode Selection
Switch again. The “Channel” LED will go out, the “Curve” LED will stay on full (not pulsing) and
the display will show “C1” – the S Law curve, or the last setting previously stored.

LSC Lighting Systems (Aust) Pty Ltd 11

V1.21 September 2007 iPAK/iPRO Dimmer Operator Manual

The S Law is the factory default setting for all dimmers. In the case of the iPAK, all channels are
permanently set to the S Law and cannot be changed.

Use the Scroll Buttons to select the desired curve. Once chosen, press the Mode Selection
Switch to select the next channel. Repeat all steps above until the set up is complete. To store
this setup, press and hold the Mode Selection Switch and the dimmer will exit the Curve function
and store the curve set up into memory. The “Curve” LED will remain on, indicating that stored
curve set ups are present in the dimmer.

In the event of power down and power then being restored, the dimmer will remember its stored
curve set up. (Note: The Curve Setup will only be committed to memory approximately 5 seconds

after the last curve change. The S Law is the factory default setting for all LSC dimmers.)

4.6 Phase Failure

In the event of a supply phase failure or disconnection, the iPAK and iPRO dimmers will indicate
to the operator which phase has dropped out or moved out of specification. The latter means that
under certain circumstances, the supply voltage and /or frequency may move outside the
acceptable operating specification and will appear as a fault to the dimmer.

Three small red LEDs are located in the top of the Status Display and labelled “A”, “B” and “C” for
phases 1, 2 and 3 respectively. A LED will flash for the respective phase number when it has
failed or been disconnected. If this fault condition occurs, it is highly recommended to shut down
the dimmer and correct the fault as soon as possible.

The dimmer’s control electronics is powered by all three phases, so in the event of any two
phases failing, the electronics will continue to operate.

4.7 Continuous Operation

The iPAK and iPRO dimmers are designed to operate at 100% Duty Cycle, they will supply full
rated load to all outputs continuously. Under these conditions the dimmer’s ventilation is critical
and good clearance around the dimmer is essential to prevent obstruction to the airflow in and
out of the dimmer chassis.

LSC recommends a general clearance of 150mm on either side of the dimmer and 200mm at the
front of the dimmer.

LSC Lighting Systems (Aust) Pty Ltd 12

V1.21 September 2007 iPAK/iPRO Dimmer Operator Manual

4.8 Fan Cooling Operation

Both dimmers use high quality ball bearing DC fans to extract hot air from the internals of the
dimmer. These fans have been chosen to operate at high temperatures and produce low level
audible noise. A temperature sensor is fitted to monitor the temperature of the internal heatsink
and vary the fan speed in the following manner:

• The fan on the iPAK dimmer will run at half speed for temperatures up to 50°C and then full
speed for temperatures over this limit.

• The fan for the iPRO dimmer will activate when the heatsink temperature reaches 40°C and
then increase fan speed in a linear fashion as heatsink temperature increases.

• On both models, the outputs will be automatically shut off when the heatsink temperature
reaches 105°C and a message “too hot” will scroll across the display. The dimmer will
automatically reconnect the outputs when the temperature of the heatsink cools to 90°C. The
fan will run at full speed during this cool down period. Dependant on ambient temperatures,
this cool down period is generally between five to ten minutes.

• If the temperature sensor fails for whatever reason, the electronics of the dimmer will drive
the fans to full speed as a default state. So if the fans are running at full speed when you
know the dimmer is running cool, then this will generally mean there is a problem in the
sensor circuitry.

4.9 User Interface Lock

The front panel User Interface settings may be locked to protect against accidental pressing of
the scroll or selection push buttons or interference from unauthorised personnel.

Note: If an error occurs while the User Interface Lock is active (on), the error messages will
scroll across the Status display, but the buttons will still be inactive. You will need to unlock the
User Interface to respond to the error.

4.9.1. Locking the User Interface panel

To lock the User Interface panel, the dimmer must be in the “Drive” state of the following three
modes. Failure to be in this mode, will result in the user not being able to lock the User Interface
panel. The three modes are: a) Channel Drive mode – refer section 4.3.1. b) Scene Drive mode
– refer section 4.4. and c) Channel Chase Drive mode – refer section 4.3.2.

Press and hold both Scroll Buttons for five seconds. You will enter the Reset function as
described in Section 5.1. The following message will then scroll across the Status Display – “sys
reset inc – yes dec – no”. INC means the increment(∧) Scroll Button and DEC means the
decrement(∨) Scroll Button. Press the decrement button to move to the next menu. This will bring
up a new message on the Status Display – “ total reset inc – yes dec – no”. Press the
decrement button to move to the next menu. The next message on the Status Display will be for
the User Interface lock – “ UI loc inc – yes dec – no”. Press the increment button to lock the
User Interface panel.

The Status Display will now scroll the following message – “UI loc active”. If you select “no”,
then the dimmer will return to the condition it was in when you started.

4.9.2 Unlocking the User Interface panel

To unlock the User Interface panel, press and hold all three push buttons simultaneously for 5
seconds. This will return the dimmer to the operating state that was active prior to locking the
User Interface panel.

5.0 SOFTWARE

5.1 Resetting the Dimmer

The iPAK and iPRO dimmers can perform two types of reset.
a) System Reset - saves all stored information, including the DMX512 Start Address

into its memory and then does a power down and re-boot of the electronic
circuitry. This is useful to reset the dimmer without disconnecting power and
maintain all stored memories.

To do a System Reset, press and hold both Scroll Buttons for five seconds. This can be activated
from any mode the dimmer is in. The following message will then scroll across the Status Display
– “sys reset inc – yes dec – no”. INC means the increment(∧) Scroll Button and DEC means

the decrement(∨) Scroll Button. Press the increment button to do the System Reset.
b) Total Reset - clears all stored memory and then does a power down and re-boot

of the electronic circuitry. This reset returns the dimmer back to its original default
position when it left the factory. The DMX512 Start Address defaults back to “1”,
the Scene Storage is blank and the curve setting for each channel is defaulted to
the “S Curve”.

For a Total Reset, repeat all the steps to do a System Reset, but press the decrement button to
say “No” to the System Reset. This will bring up a new message on the Status Display – “ total
reset inc – yes dec – no”. Press the increment button to do the Total Reset. At this point if
you do not wish to proceed with the Total Reset, press the decrement button to exit.

5.2 Software Upgrades

Future Software upgrades are possible by returning the Dimmer to LSC Lighting Systems (Aust)
Pty. Ltd. or its distributors, or by the CodeLINK option.

CodeLINK is a PC based software program that allows the uploading of Software releases to the
dimmer from a PC style computer or laptop. Latest Software releases will be available via email
at [e-mail] or from downloading at LSC’s Web site –
www.lsclighting.com.au. Included with the CodeLINK option is a serial cable that connects the
computers serial port to the DMX512 input connector on the dimmer, a 3.5” floppy disk
containing the latest software and an instruction sheet.

Using the spare two pins on the DMX512 connector, new data can be sent from the PC or
Laptop to update the dimmers ROM (Read Only Memory).
