1. Introduction
Lumencor AURA light engines are designed for laboratory use by bioanalytical researchers and/or developers of biooptical instrumentation. The AURA provides 2, 3, 4, or 5 individually controllable solid state light sources that have
been optimized to produce spectrally discrete spectral outputs.
This manual covers all AURA II models identified by the designation
AURA II X-YYY-ZZ on the identification label affixed to the back panel
of the light engine. X denotes the number of sources, YYY denotes a
unique customer code and ZZ denotes options and revisions. Any
reference to “AURA” in this manual shall apply to all AURA II models
unless noted otherwise.
The light sources within the AURA are controlled by a serial command
interface connecting to the Lumencor light engine control pod
accessory (83-10007) or a computer running a Lumencor supplied
GUI or a third party microscopy software application. Alternatively,
the light sources may be enabled by TTL inputs from a trigger device
such as a camera. The user can enable or disable each source
independently (serial or TTL) and change the intensity of each source
independently (serial only). The only manual control is a power switch on the front panel to turn on/off the electrical
power supply to the unit. A green indicator above the power switch is lit when the power supply is connected to the
AURA and the power switch is in the on position (see Figure 3, below).
2. Precautions and Warnings {Précautions et mises en garde}
A few simple practices will ensure trouble-free operation for the life of the light engine.
Les quelques règles simples suivantes permettront d’assurer un fonctionnement fiable pendant toute la durée de
service de la source lumineuse.

3. Installation and Operating Instructions!
All AURA family light engines ship with the following list of standard components:
1.
AURA light engine, configured with three, four or five solid-state light sources (color channels). The output of
each source is refined by a bandpass filter. Bandpass filters are installed to order according to customer
specifications and are not user-exchangeable. The filter configuration for each AURA light engine is shown on
the certificate of conformance issued to the customer when the light engine is shipped by Lumencor (Figure 2).
2.
A 24V/9.2A (220 W) DC power supply (Lumencor part no. 27-10019)
3.
A 6ft AC power cord for the power supply (for North American customers, Lumencor part no. 29-10002, for UK
customers, Lumencor part no. 29-10004 and for European customers, Lumencor part no. 29-10005).
4.
A USB A-to-RS232 cable (Lumencor part no. 29-10011) or USB B (M) to USB A (M) cable (Lumencor part no.
29-10058)
AURA Light Engine Instruction Manual

AURA light engines incorporate fan-assisted air cooling. When positioning the AURA for use, place the unit on a
hard surface and avoid blocking or restricting airflow at the air intake (front panel) and exhaust (rear panel) ports.
Restricting the airflow will cause the unit to operate at elevated temperatures and will result in decreased operating
lifespan and/or premature failure.
AURA light engines 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.
The AURA can be controlled via serial commands delivered through the RS-232 port from the Lumencor light engine
control pod accessory (83-10007), a Windows GUI (free download from www.lumencor.com) or via customersupplied instrumentation control software. Serial commands provide controls for on/off switching and intensity
adjustment (0 to 100% in 1% increments) of individual color channels. Refer to Figure 3 for the location of the
various connectors. TTL signals delivered to the DB15 connector (Figure 3) provide high speed (10 µs) on/off
switching of individual color channels.!

11.
Press the “INIT” button in the GUI
12.
The computer should now have control of the AURA. Graduated sliders control the source output intensity
for each color channel. ON/OFF buttons for each color channel are located below the respective slider
controls [2, 3].
Notes
[1] On some AURA models, the port is USB B and the connecting cable is USB B (M) to USB A (M).
[2] The identity of the source outputs corresponding to control channels 1–5 differs among AURA light engine
models. If you are unsure of the correspondence, please contact our Technical Support Group (see Section
7). Please provide notification of the serial number of your AURA light engine with your inquiry.
[3] Two luminescent light pipe sources (e.g. Green and Yellow, Figure 5A) cannot be ON simultaneously.
3.2 Light Engine Control Pod Interface!
1.
Connect the USB A port of the light engine control pod accessory (83-10007) to the DB9 port on the
AURA (Figure 3) using the USB-to-RS-232 cable (29-10011) [1]. Connect the USB B port of the control
pod to a USB A port on a host computer. For applications not requiring a host computer, connect a DC
power supply (5V/500mA) to the USB B port.!

available color channels.
4.
Press the right button to turn the selected light source on. Adjust the output intensity using the rotary dial.
Press the right button again to turn the selected light source off.
5.
Press and hold the left button to obtain digital output intensity settings for each color channel [2]. Press
the right button to return to the main display screen.
Notes
[1] On some AURA models, the port is USB B and the connecting cable is USB B (M) to USB A (M).
[2] The current intensity settings are internally stored. When the pod is powered down, the settings are
retained and will be restored at the next restart.
3.3 TTL Interface!
The TTL Interface provides users with a faster method of switching color channel outputs on and off. Individual TTL
lines are provided for each color channel. These can be conveniently addressed using an accessory BNC breakout
cable (Lumencor part no. 29-10015 or 29-10080) connected to the front panel DB15 port (Figure 3). As a
safeguard against unintended light output when the inputs are initially connected, the TTL port is disabled and must
be enabled by a serial command. To enable the TTL port, establish a serial connection as described in Section 3.1
and click the TTL ON (SFT) button in the GUI. A description of the serial command string for this operation is
available on request from Lumencor Technical Support (Section 7). Note that TTL and serial on/off commands have
a logical OR relationship. Therefore on/off controls in the GUI or other serial control software must be set in the
“OFF” state when using TTL control. TTL polarity (ACTIVE = HIGH or ACTIVE = LOW) is factory set according to
order specifications. TTL polarity can be reversed using controls provided in the GUI.
