1. Introduction
The MAGMA Light Engine consists of 21 individually addressable solid-state light sources with
integrated electronic control systems. The constituent light sources may be LEDs or luminescent
light pipes. The outputs of the constituent light sources are refined by bandpass filters and merged
into a common optical train directed to the light output port on the front panel. The light output port
has a built-in adapter for connection to an optical fiber bundle. An onboard photodiode
continuously monitors the light output and generates a reference signal that can be applied to the
constituent sources in a feedback loop to maintain constant light output over time. The light sources
within the MAGMA Light Engine are controlled by an on-board microprocessor operating Lumencor
firmware accessed via one of two serial interfaces, USB/RS-232 or TCP. The user can
independently enable or disable each source by serial commands as well as change the intensity of
each source. The MAGMA Light Engine can either be controlled by a GUI resident on the on-board
microprocessor. Alternatively, the light sources may be turned on and offby TTL inputs from a
trigger device such as a camera or real-time controller. Optimal internal operating temperature is
maintained by negative pressure air cooling with the air intake at the front of the Light Engine and
the exhaust fan at the the rear.!

and certification markings of the light engine are carried on a
label affixed to the rear panel . Performance specifications
for individual light engines are listed on the certificate of
conformance included with the shipping documents e-mailed
to the customer (Figure 1).!
3.2 Installation
NOTE: Any end-product/system incorporating or coupled to
a Lumencor Light Engine shall be fully evaluated to verify all
applicable safety and regulatory compliance requirements
prior to use.!
When setting the MAGMA Light Engine up for use, place the
unit on a hard surface and avoid blocking or restricting
airflow at the air inlets (front panel; Figure 3) or exhaust ports
(rear panel) on the enclosure. Restricting the airflow will
cause the unit to operate at elevated temperatures and will
result in decreased product life and/or premature failure.!
The MAGMA Light Engine must be operated in a non-
condensing environment (dew point <10ºC with controlled
ambient temperature <30º C). Thermal overload protection
is provided by the onboard microprocessor in conjunction
with an onboard temperature sensor. If the internal
temperature registered by the sensor exceeds 50°C or the
fan rotor is stopped, all light output channels automatically
turn OFF and are locked in this state until the internal
temperature is below 50°C and/or the fan restarts. The
current reading of the onboard temperature sensor is
displayed on the front panel status display (Figure 3) and in
the Control GUI (Section 3.3.3)!
Connect the DC power supply to a grounded AC wall
outlet using the power cord supplied with the light engine.
Connect the DC output to the 6-pin receptacle on the front
of the light engine (Figure 3). Turn the light engine on using
the master power switch. The embedded green indicator
will illuminate (if applicable, ensure that the liquid light

The MAGMA Light Engine may be configured for light delivery via a 3 mm liquid light guide or an
SMA-terminated optical fiber. The output couplers are built into the light engine front panel and are
not field-exchangeable (Figure 3). The 3 mm liquid light guide output coupler incorporates an
electrical power interlock switch in the back of the receptacle. The liquid light guide must be fully
inserted in the receptacle to activate the interlock. Electrical power supply to the light engine cannot
be turned on via front panel power switch until the interlock is activated. After fully inserting the
liquid light guide, lock it in position using the set screw on the side of the receptacle to prevent
inadvertent disconnection of the light guide during use.!
3.3 Operation
3.3.1 Controls and Interlocks
The Master Power Switch button on the front panel (Figure 3) turns the electrical power to the unit
on or off. A green power indicator embedded in the button is lit when the power supply is
connected to the light engine and the power button is in the on position. Initialization of the onboard
computer takes about 30 seconds after the master power switch is turned on. When initialization is
complete, the status indicator display (Figure 3) will activate.!
The Key Control (Figure 3) must be in the on position before light output can be turned on. The key
must be removed and stored in a secure location when the product is not in use. ONLY trained
individuals should use and have access to the key. The Master Power Switch button, Key control
and Remote interlock (Figures 3,4) can be used to shut offlight output.!
The Source Enabled indicator LED (below the status indicator display, Figure 3) provides a warning
indication that one or more light sources are active and emitting invisible and/or visible radiation.!
The Remote Interlock Connector: (Figure 4) is provided to allow for connection of a remote
interlock. When this interlock is open it will shut offlight output. After the interlock has been
opened, the Manual Reset button will need to be pushed to resume light output.!
WARNING:#The Remote Interlock relies on a passive continuity circuit for proper operation.#It does
not provide a voltage source for external circuitry, nor can external voltage sources be applied to it.
UNDER NO!CIRCUMSTANCES should a voltage or voltage source be applied to the Remote
Interlock circuit.##APPLYING A VOLTAGE OF EITHER POLARITY MAY RESULT IN ANOMALOUS

verify the output end of the liquid light guide or optical fiber is safely directed into an enclosed
optical path (e.g. a beam dump).!
Notes:
1Ensure that the distal end of the light guide or optical fiber is safely directed into an enclosed
optical path (e.g. microscope epi-illuminator or a beam dump) before turning the light output on. If
the light engine is equipped with an output adapter for an SMA-terminated optical fiber, connect the
fiber to the output adapter using the integral threaded sleeve. !
2To enable light output of the MAGMA Light Engine the external gate jumper, control key, remote
interlock jumper, and Liquid light guide must be inserted. !
3For subsequent start ups, use the master power button to start or shut down the light engine.
Shut down can also be accomplished using the “Shut Down” button in the GUI (Figure 5, left).!
3.3.3 Ethernet Connection and Control GUI
The Web GUI provides a quick and easy way to control the light engine, providing the ability to turn
each source on/off, adjust the power of each source independently from offto full power (Figure 5).
The GUI also tracks the total on time and displays real-time power sensor readings. To set up the
Web GUI, follow the follow protocol below:!
1. Go to Start menu > Control Panel > Network & Internet and/ or Network & Sharing Center!
2. Click Change Adapter Settings!
3. Right-click on Local Area Connection!
4. Click on Properties (in pop-up)!

8. Connect the RJ45 cable (supplied with the light engine) between the LAN port on the light engine
and an ethernet port on the computer.!
9. Type the Light Engine IP address (Figure 3) into any web browser address bar to access the
resident Web GUI. The factory default IP address is 192.168.201.200!
Output power regulation allows users to eliminate variations in light output due to temperature
fluctuations and other environmental factors in photometric and quantitative imaging applications
where reproducibility and accuracy are essential. To use power regulation, a desired power reference
value in milliwatts is entered in the onboard control GUI. To activate power regulation, simply click
the padlock icon next to the reference power value. Gray shading of the padlock icon and the
reference power value shows that power regulation is active for the selected output channel. When
power regulation is active, the intensity setting for the channel is controlled by the onboard
microprocessor, based on feedback from the light engine’s reference photodiode array. The
microprocessor continuously adjusts the intensity setting so that the output power matches the
power reference value set by the user.!
3.3.4 Control via Serial Ports
MAGMA Light Engine have two serial ports, labeled USB and RS-232 (Figure 3), which can be set to
receive either LEGACY or STANDARD mode commands. Connection to the computer requires a
USB-A-to-USB B cable (29-10058) or USB-to-RS-232 cable (29-10011). LEGACY commands are
limited to controlling on/offswitching and intensity adjustment of individual color channels. Only one
of the two ports can be set to LEGACY mode at one time. The STANDARD mode command set

gives access to an extensive panel of operating status reports and configuration settings in addition
to the the basic control functions of the LEGACY command set. A complete listing of STANDARD
mode commands is provided in Lumencor Light Engine Command Reference (Document number
57-10018). Note that LEGACY and STANDARD mode communications use different serial protocols
(9600,8,N,1 and 115200,8,N,1 respectively). Changes to the command mode setting for a serial port
can be made via the Settings screen of Web GUI (Figure 6). Changes are applied instantaneously
and are retained between power cycles.!
In the Web GUI, select the serial port command mode setting that is compatible with the light engine
device driver in the control software. The COM port address assigned by the computer to the light
engine USB serial port must be correctly registered. These selections are typically found under the
“Devices” tab in the control software.!
3.3.6 TTL Control
The TTL Interface provides users with a faster method of switching color channel outputs on and off.
The TTL interface does not control source output intensity, which remains under serial (RS-232/USB/
TCP) control. Note that TTL and serial on/offcommands have a logical OR relationship. Therefore
source on/offcontrols on the light engine control pod, in the Web GUI or in third-party image
acquisition control software must be set in the “OFF” state when using TTL control. Individual TTL
inputs are provided for each color channel, as shown in the adjacent table. As a safeguard against
unintended light output when the inputs are initially connected, the
light engine TTL port is disabled and must be enabled by a serial
command. To enable the TTL input, click the Enabled button next to
“TTL inputs” in the GUI under the Settings tab (Figure 6) or send the
standard mode command SET TTLENABLE to the LAN port. Input
TTL signals can be conveniently addressed using an accessory BNC
breakout cable (Lumencor part no. 29-10240) connected to the front
panel TTL port. The breakout cable also provides a global shutter
input (labeled “shutter”). TTL signals input to the global shutter will
synchronously toggle all currently enabled source channels on and
off.!
4. Light Output Characteristics
MAGMA Light Engine may incorporate different types of solid state light sources. Constituent light
sources may include LEDs or luminescent light pipes. The light sources installed and the bandpass
filters associated with each are shown on the Certificate of Conformance included with the shipping
documents e-mailed by Lumencor to the customer. The certificate of conformance also shows full
(100%) power outputs for each source measured at the terminus of the optical fiber bundle (Figure

1). Not all sources may be turned on simultaneously. To prevent exceeding the capacity of the DC
power supply, power consumption is tracked by the onboard microprocessor. If a set limit (see
Governor, Figure 5) is exceeded, either by increasing intensity settings for sources that are already
on, or by turning on additional sources, all light output is terminated and an error message will be
displayed on the control screen. To clear the error condition, click on the System tab in the GUI and
then click the Restart button under Governor.!
Light source outputs are refined by bandpass filters. The specifications of these bandpass filters are
recorded on the certificate of conformance as CWL/FWHM where CWL =center wavelength and
FWHM = full width at half-maximum transmission, both measure in nanometers (nm). In
fluorescence microscopy applications, it is usual to remove the exciter from the microscope filter
cube to facilitate fast electronic excitation switching. Compatibility of the bandpass filters with the
transmission characteristics of the dichroic beamsplitter and emission filter in the microscope cube
is required to maximize transmission of excitation light to the sample and to avoid excitation bleed-
through. Bandpass filters installed in the MAGMA are not user-exchangeable. Changes to the filter
configuration require return of the light engine to Lumencor’s factory for service (see Section 7).
Since changing bandpass filters will result in source output power changes, a new certificate of
conformance will be provided as part of this service.!
5. Operational Specifications
The MAGMA Light Engine must be operated and stored within the environmental conditions
specified in the table below. Performance specifications for individual light engines are listed on the
certificate of conformance included with the shipping documents e-mailed to the customer (see
example shown in Figure 1). It is important to retain the certificate of conformance for reference. In
the event that the light engine is sold, the certificate of conformance should be transferred to the
new owner. Certificates of conformance are also recorded in Lumencor’s database and copies can
be requested by e-mail to [e-mail]. The request message must include the 5-
digit serial number of the light engine.!

Troubleshooting Procedures
Problem
Check the following
No response to serial (USB or
RS-232) commands
Check that the LEGACY or STANDARD command mode selection (GUI
Settings; Figure 5) is compatible with the software driver.
No response to TTL trigger
commands
Check that TTL inputs are ENABLED (GUI Settings; Figure 6) and that
the TTL polarity setting is consistent with the trigger inputs. Also check
that all serial ON/OFF controls are in the OFF state.
No light output in response to
source ON command (serial or
TTL).
There are 4 interlocks that need to be closed, check all of these:!
1. Liquid light guide must be inserted in light output receptacle¹.!
2. Remote interlock jumper must be inserted in rear panel¹.!
3. External gate jumper must be inserted in front panel (Figure 3).!
4. Control key must be inserted in front panel and turned to “on”
position¹.
Unusually weak fluorescence
signals across all detection
channels
Weak fluorescence in all detection channels (DAPI, FITC, TRITC, Cy5 etc)
is likely to be due to poor light transmission by the liquid light guide, the
collimating adaptor or another distal component of the microscope
optical path and not to abnormally low light output from the light engine.
