    1. OFF mode: Turns off the light and disables the output of the selected channel.

      Off Mode

    2. ON mode: Turns the light on permanently. In this mode you can only configure the brightness. The brightness can range from 0 mA to the current limit.

      On Mode

    3. Trigger follow mode: In this mode, the light is controlled by a trigger signal, so you can use it as a strobe light. The brightness can range from 0 mA to the overdrive limit.

      Trigger Follow Mode

    4. Trigger start mode: In this mode, the light is turned on by a trigger signal and stays on for a certain amount of time, so you can use it as a strobe light. The brightness can range from 0 mA to the overdrive limit.

      Trigger Start Mode

To configure the light in these modes, use the BRT/FUNC button. You can rotate the BRT/FUNC button or press it.

BRT/FUNC Button

With the BRT/FUNC button, you can configure the following settings:

Defining Current Limit and Overdrive#

The current limit defines the maximum current the controller may supply and therefore equals 100 % brightness. Check the documentation of your light to find out about its maximum allowed current.

The overdrive limit defines the maximum current the controller may supply in overdrive mode, which allows brightness levels above 100 %. Basler recommends using overdrive in strobe mode only, where you must also define the duty cycle. Check the documentation of your light to find out about its maximum allowed overdrive and duty cycle.

  1. Press the CHL_SEL and BRT buttons simultaneously.
  2. Press the BRT button again to change between current limit (CL) and overdrive limit (OdL).
  3. Rotate the BRT button clockwise or counter-clockwise to increase or decrease the limit.
  4. Press the BRT button to confirm the setting and to exit the current limit setup.
    The display shows the mode of the selected channel.

BRT Button: Current Limit and Overdrive Limit

NOTICE – Currents outside of the specified output current range may damage the LEDs of the light.

You must supply the light with the correct output current, overdrive, and duty cycle as provided in the documentation of your light. If you don't adhere to these values in the configuration of your controller, the LEDs of your light might be damaged.

Adjusting the Brightness#

  1. Rotate the BRT button until the mode of your choice is displayed (ON, Trigger Start, or Trigger Follow). Then press the BRT button once.
  2. To increase the brightness, rotate the BRT button clockwise.
  3. To reduce the brightness, rotate the BRT button counter-clockwise.
  4. Press the BRT button to confirm the setting.

By default, the brightness display shows the current in mA. If you rotate the BRT button so that the brightness exceeds 995 mA, the unit switches from mA to A.

Also, the step size changes from 5 mA per step to 10 mA per step, and the A/mA LED lights up:

Operating the Controller in Ethernet Mode via Web Interface#

To configure your controller via web interface:

  1. Connect the controller to a host computer using an Ethernet cable.
  2. Switch the mode selector to ETHERNET.
  3. Make sure your Ethernet port on the host computer is set to the same IP range and subnet mask as the controller:
    • Default IP address: 192.168.1.2
    • Default IP range: 192.168.1.1192.168.1.255
    • Default subnet mask: 255.255.255.0
  4. Open a browser on the host computer and enter the following address: 192.168.1.2.
    This is the default address for the web interface. The IP address is also displayed on the controller:

    4C Controller: IP Address

    If the controller displays 000, the controller isn't connected to an existing Ethernet port:

    4C Controller: IP Address not Found

The web interface opens with the Controller Info page:

4C Controller Web Interface: Controller Info

Configuring IP Address and LAN Settings#

On the Controller Info page, you can see all defined settings regarding LAN status and versions. To configure the LAN settings, open the LAN Settings page:

4C Controller Web Interface: LAN Settings

You can configure the following settings:

  • DHCP On: Choose this option if you're using a DHCP server in your network. The DHCP server automatically assigns IP addresses. To find out whether your computer is connected to a DHCP server:

    1. Open the Windows control panel.
    2. Select Network and Sharing Center.
    3. Click Ethernet.
      The Ethernet Status dialog opens.
    4. Select Details.
      The Network Connection Details dialog opens. If DHCP Enabled is set to Yes, then DHCP is enabled.

      DHCP Enabled

  • DHCP Off: Choose this option if you want to configure the IP address manually. Make sure that you use an IP address which isn't used by any other device in the same network. It's common to keep the first three numbers for all devices in the same network and change only the last number. For example, if a device in your network has the IP address 192.168.1.1, you can assign 192.168.1.2 as the controller's IP address.

Configuring Current Limit and Overdrive Settings#

In the web interface, open the Current Limits page.

4C Controller Web Interface: Current Limits

The current limit defines the maximum current the controller may supply and therefore equals 100 % brightness. Check the documentation of your light to find out about its maximum allowed current. Then, configure the maximum current limit in the Max field of the desired channel and click Set.

The overdrive limit defines the maximum current the controller may supply in overdrive mode, which allows brightness levels above 100 %.

To use overdrive in strobe mode, you must also define the duty cycle for the strobe mode, either in your trigger device or via the ON Time parameter on the Controller Settings page. Check the documentation of your light to find out about its maximum allowed overdrive and duty cycle. Then, configure the overdrive limit in the Overdrive field of the desired channel and click Set.

NOTICE – Currents outside of the specified output current range may damage the LEDs of the light.

You must supply the light with the correct output current, overdrive, and duty cycle as provided in the documentation of your light. If you don't adhere to these values in the configuration of your controller, the LEDs of your light may be damaged.

Configuring Your Lights#

In the web interface, open the Controller Settings page.

4C Controller Web Interface: Controller Settings

You can configure the following modes for each channel:

4C Controller Web Interface: Modes

  1. OFF mode: Immediately turns off the light and disables the output of the selected channel.
  2. ON mode: Turns the light on permanently. In this mode you can only configure the brightness. The brightness can range from 0 mA (i.e. 0 %) to the current limit (i.e. 100 %).
  3. Trigger follow mode: In this mode, the light is controlled by a trigger signal, so you can use it as a strobe light. The brightness can range from 0 mA (i.e. 0 %) to the overdrive limit (i.e. 100 %).
  4. Trigger start mode: In this mode, the light is turned on by a trigger signal and stays on for a certain amount of time, so you can use it as a strobe light. The brightness can range from 0 mA (i.e. 0 %) to the overdrive limit (i.e. 100 %).

If you select Trigger Follow or Trigger Start, you can use the Trigger drop-down to define whether a high or low signal transition starts the trigger.

If you select Trigger Start, you can use the ON Time field to configure the duration of the strobe light (i.e., the active part of the duty cycle).

Click Execute to apply your changes. For safety reasons, the light is turned off, and it takes a few seconds before the Execute button is available again.

You can save your configuration to a .txt file via the Save File button.

You can load a configuration file and restore saved settings in the Load File pane:

4C Controller Web Interface: Saving the Configuration

After clicking Choose file, select the right file from your file system. The settings to be loaded for all channels will be shown on the Controller Settings page.
