AURA Light Engine Instruction Manual

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 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.

3. Installation and Operating Instructions

All AURA family light engines ship with the following list of standard components:

1. AURA light engine, configured with two, 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-to-RS232 cable (Lumencor part no. 29-10011).

AURA Light Engine Instruction Manual

Figure 2. Specimen certificate of conformance for AURA Light Engine.

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.

AURA Light Engine Instruction Manual

3.1 GUI Installation and Operation

1. Operation and installation of the AURA GUI requires a computer running the Windows operating system with a free USB port.

2. Download the zip file for the AURA GUI from http://lumencor.com/resources/documentation-software/ .

3. Unzip the file and run setup.exe to install the AURA GUI.

4. Connect the USB-to-RS-232 cable between the computer and the DB9 RS-232 port on the AURA (Figure

3).

5. Successful installation is indicated by the appearance of “USB Serial Port (COM #)” under the “Ports (COM

&LPT)” tab in the Windows Device Manager. If the virtual COM port (VCP) is not registered by the operating system, download and install the VCP driver from http://lumencor.com/resources/ documentation-software/.

6. Connect the DC power supply to the AURA.

7. Check that the liquid light guide is fully inserted and locked in the front panel receptacle (Figure 3).

8. Toggle the power switch on the front panel to the ON position. The green LED above the switch (Figure 3) should light.

9. Run the GUI by going to the Program Menu and selecting LLE Controller.

10. In the COM pulldown menu (GUI window, upper left), select COM # assigned to USB-Serial port.

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.

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). 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.

2. Press and hold the right button on the pod until a menu of light engines appears. Turn the rotary dial to select “AURA” from the menu. Press the right button again to return to the main (0–100 analog intensity) display screen.

3. Press the left button to select the desired color channel. Successive presses will cycle through the 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 [1]. Press the right button to return to the main display screen.

Notes:

[1] 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.
