DC4100 1 General Information

1 General Information

Thorlabs' DC4100 four-channel LED controller is designed for microscopy and other applica-

tions that require multiple color channels. It is the ideal driver for the LED4D series of four-

wavelength LED sources. Via the optional DC4100-HUB, it can concurrently drive 4 LEDs like

the Thorlabs collimated or uncollimated mounted LEDs . Using the DC4100-HUB connector

hub and 4 CAB-LEDD1 connection cables, the driver can also be used with 4 Thorlabs LEDs

on metal-core PCB or with 4 user-supplied LEDs. The LED current of each channel can be ad-

justed independently from 0 to 1000 mA or modulated via an external voltage.

The DC4100 can be operated in constant current mode (setting the LED current in mA), bright-

ness mode (setting the LED as a percentage of its maximum current) or external control mode,

applying modulation through an external signal generator.

Additionally, the LED driver can be operated remotely via the USB 2.0 interface by the DC410x

software package. The LED drivers are also compatible with µManager, a versatile, open

source, GUI software platform for automated microscopy. A plugin allows the user to control the

LED drivers right out of the box.

The DC4100 controls all activated LEDs by the same modulation signal while each LED can be

individually deactivated. The controller accepts voltages ranging from 0 to 10 V, with 1 V corre-

sponding to an LED current of 100 mA.

DC4100 2 Getting Started

2 Getting Started

2.1 Parts List

Please inspect the shipping container for damage. Please do not cut through the cardboard, as

the box might be needed for storage or returns.

If the shipping container appears to be damaged, keep it until you have inspected the contents

for completeness and tested the DC4100 mechanically and electrically.

Verify that you have received the following items within the package:

1. DC4100 LED Driver

2. Power Supply (12V / 5.5A)

3. Power Cord, Connector According to Ordering Country

4. USB 2.0 Cable

5. Quick Reference

2.2 Preparation

1. Connect the cable from the LED4Dxxx four-color light source to the socket labeled 'LED' at

the back of the main control unit.

2. Alternatively, a DC4100-HUB can be connected to this socket. This allows to drive up to 4 of

the supported LEDs via the standard Thorlabs LED connector. Please see the figure be-

low. For PCB mounted LEDs, please use the CAB-LEDD1 adapter cable.

3. Connect the power supply cable to the main control unit. Please use only the power supply

which is included in the shipment of the DC4100 unit.

4. Plug in power supply.

5. Turn the unit on by pressing the power switch on the rear side of the unit.

6. After the device is powered up, the graphics display will show a 'Welcome' screen for a few

seconds.

7. The rated accuracy of the DC4100 is reached after a warm-up period of approximately 10

minutes.

DC4100 3 Operating Instructions

3 Operating Instructions

The DC4100 can be ontroled directly ont he device or remotely via the DC41xx software.

In the device, the DC4100 is controlled by three buttons and the multi-control knob on the front

panel. Please see the chapter Operating Elements . The two buttons below the graphics dis-

play have an Escape and Enter (OK) functionality. The 'LED' Button is used to switch LED(s)

on or off. The multi-control is used to select the desired menu or to change the settings.

After switching on the DC4100 a 'Welcome' screen appears for a few seconds.

In case no LED head is connected you will be prompted to switch off the main unit, connect the

LED head and switch on the device.

The display will show the screen of one of the three LED operation modes (Constant Current,

Brightness or External Control Mode). The 'Main Menu' can be accessed via the 'ESC' button.

To select an operation mode or a configuration display the multi-control knob is used. Press the

'Ok' button to enter the selected item.

3.1 Operating Elements

Operating elements on the front panel

Operating elements on the rear panel

3.2 Operation Modes

For safety reasons the LED can be switched on only if one of the three operation modes (Con-

stant Current, Brightness or External Control) is selected.

It is possible to leave the active mode when the LED is switched on and enter the main menu.

However, the LED needs to be switched off before you can enter another operation mode. This

can be done while the main menu is selected by pressing the LED button.

The last selected operation mode will be saved. After switching on the DC4100 again this oper-

ation mode will be automatically restored. All settings are saved and validated after a shut off.

3.2.1 Constant Current Mode

The 'Constant Current Mode' provides a constant non-modulated LED current.

The actual current for each channel is displayed. If you connected a supported Thorlabs

LED (features and EEPROM) or the 4 Color LED LED4Dx, the corresponding wavelength

will be displayed instead of the channel number. There are two different output modes, 'Single

Selection' and 'Multi Selection'. The output mode can be selected in the 'Setting' menu (see

Settings) .

The 'Multi Selection Mode' is illustrated by square indicators. More than one LED at a time can

be switched on. This is indicated by the check mark in the square box.

The 'Single Selection Mode' features circles as output indicators, which are filled with a dot

when the LED is on. Only one LED at a time can be switched on within this mode. This eases
