Connection Setup

Step 1: Refer to drawing above on how to connect the light with the controller.

Step 2: For external triggering, connect the external trigger source with the trigger port.

Step 3: Connect the controller with 100 - 240V AC power source and switch the controller on. The digital display is lit. 

            If the intensity of the light shall be controlled via PC, 

            you need to connect the PC with an RS232 cable or Ethernet cable before the controller is switched on. 

            Use the provided software or your own application to communicate with the controller. 

            You can adjust the settings via the PC or manually.
