Safety Information
1.1 Important Safety Information
Light-emitting diodes (LEDs) used with sufficiently high power levels can be dangerous for the eyes. NEVER LOOK di-
rectly into the beam exiting from the FC connector of an LED module or from any optical fiber connected to the FC
connector.
Doric LED Drivers are provided with a safety interlock connector on its rear panel (Fig. 1.1a). When the interlock circuit
connector is shorted with the interlock plug, the driver is enabled. The shorting electric wire in the interlock plug can be
removed and replaced by the safety interlock circuit of the laboratory. This safety feature is highly recommended with
UV and infrared (IR) LEDs.
The Power Key Switch is located on the left side of the driver (Fig. 1.1b) to control the use of the device. All light sources
connected to the driver can be enabled only when the power key is properly inserted.
To be enabled, LED Drivers must have its interlock circuit connector shorted with the interlock plug and
the power key properly inserted.

Overview
2.1 Connectorized LEDs
Figure 2.1: Connectorized LED
The Doric Connectorized LED is a compact module that couples a high brightness LED into an optical fiber via an FC
receptacle. It is available in wavelengths from 365 nm to 940 nm, as well as white (5500 K temperature). The module
connects to the Doric LED Driver over the pigtailed M8 electrical cable. Each module contains a fan, which is powered
using a micro USB 5 V power supply. This fan cools the LED and allows stable output performance and long device
lifespan. The following elements are found on the outside of the light source.
• The output beam exits from the Beam aperture. The aperture is composed of a fiber coupling assembly that injects
the emitted light into an optical fiber. The standard model uses an FC fiber connector. A safety FC metal cap is
attached to the optical head to block the output light beam when no patch-cord is in place.
• The Fan grids are found on the top and sides of the light source.
• The M8 electrical cable links the light source to the driver. An EPROM within the light source allows the driver to
identify it when the cable is connected.
• The Power input is a 5 V micro-usb port used to power the fan.
• The Power output is a 5 V micro-usb port. A micro-usb/micro-usb cable is used links the port to the Power input
of a different LED.

2.2 LED Drivers
Figure 2.2: LED Drivers; 1-, 2- and 4-channel
Doric LED Drivers can be used as a stand-alone device or controlled via USB port. Each channel connects to a single
Connectorized LED which can be controlled manually or via the Doric Neuroscience Studio Software.
The LEDs drivers can be used as a stand alone device. During stand-alone operation, it is possible to change the operating
mode (CW or external analog mode) and the current sent to the Connectorized LED. These changes can be done directly
on the device with the control knobs and the LCD display.
Connecting the LED drivers to a computer provides the user with more options. Doric Neuroscience Studio Software
allows the access to more operating modes like CW, external TTL, external analog, internal TTL and internal Complex
modes. Doric Neuroscience Studio Software enables the creation of different sequences of light source activation. It
also provides the possibility to let these sequences be triggered or paused by an external signal. If more power is needed,
it is possible to overdrive the LED driver with the software. Our LED driver has a live pulse capability allowing the
visualization of the signal modulation on the input BNC in a scope-like manner.
Figure 2.3: Front view of a 4-channel LED Driver
• The LCD display (Fig. 2.3) allows easy operation and monitoring. For each channel, the LCD displays the type of
light source (LED), the operating mode, the center wavelength in nm and the current setting.

• The Power key must be properly inserted into the key switch to enable operation of the light source(s) connected
to the driver. Note that, despite its similar shape, the power key is not a standard micro SD card such as those used
in some digital cameras. Do not attach the Key to a key fob or similar holder; this may prevent proper insertion of
the Power key.
• The M8 connector is used to link the driver and LED.
Figure 2.4: Rear view of a 4-channel LED Driver
• The Interlock Connector Plug (Fig. 2.4) allows the user to connect the driver to an interlock system. It is recom-
mended to connect the interlock plug to a laboratory interlock system. This is critical when using LEDs in the UV
or Infrared spectrum, as they are invisible to the naked eye.
• The Input BNC allows the control of the LED driving current of the corresponding source with an analog or TTL
signal.
• The Output BNC are used to monitor the driving current of the corresponding light source.
• The 12 VDC power input connects the driver to its 12 VDC power supply.
• The USB-B Connector allows the driver to be connected to a computer using a USB-A/USB-B cable.
• The On/Off switch (Fig. 2.5) turns on/off the driver.

2.3 LED Breadboard
The LED Breadboard is a small breadboard used to hold two Connectorized LEDs; this allows the light sources to be easily
moved when necessary. It is ordered separately from the light source.

Operations Guide
3.1 Connectorized LED Setup
Figure 3.1: Connections to a 1-channel LED Driver in stand-alone mode
1. Connect the LED Driver to the 12 VDC power supply.
8
2. Connect the Connectorized LED (CLED) to the driver. Align the M8 connector pins in the female receptacle on
the Doric CLED driver, slide in and screw the nut in place.
3. Connect the 5 VDC Micro-USB Power Supply to the 5 V Input of the CLED Fan for proper cooling of the LED.
4. For optimal performances, place the module in a well ventilated area. Overheating will affect LED power and
reduce its lifetime.
•DO NOT connect/disconnect the optical fiber while the light source is ON.
• The CLED can be operated with the driver’s stand-alone capabilities (Section 3.3) or using the Doric Neuro-
science Studio software (Section 3.4).
3.2 FC Connector Installation
1. Clean the optical fiber connector before insertion. Use isopropanol and a lint-free wipe.
2. With an FC connector, the connector key must be oriented to enter within the receptacle slot to ensure proper
connection (Fig. 3.2).
Figure 3.2: FC connector, Fiber Installation
To reduce the risk of eye injury, it is sound practice to NOT CONNECT/DISCONNECT OPTICAL
FIBERS when the light source is turned on.

3.3 Stand-alone mode (without Doric Neuroscience Studio Software)
The following sections details stand-alone operation of the LED driver. For installation of the LEDC in stand-alone mode,
see section 3.1.
3.3.1 Driver operation modes with the stand-alone device
If the light source driver is used as a stand-alone device, 3 modes are available: constant current (CW), external TTL (Ext.
TTL), and external Analog (Ext. Ana). The operating mode is changed by pressing the Control knob. The maximal driving
current is set by turning Control knob. Use a fast/slow rotation for coarse/fine adjustment. The operating mode and the
maximum driving current setting are independently adjusted for each channel.
Constant current (CW)
Figure 3.3: Constant Current Mode Driver Signal
When using the CW mode, the user simply sets the driving current applied to the light source. The light source is acti-
vated and an output beam will be visible as long as the driving current is above the minimum driving current (Fig. 3.3).
External TTL (TTL)
Figure 3.4: Driver Signal Response to External Source in External TTL Mode
In the External TTL mode, the driver is activated by an input TTL signal coming from an external device. This activation
will follow the TTL pulse waveform. The driving current is set with the control knob, and is constant during each TTL
activation pulse.
