Device Overview





4-digit display

The first number indicates the channel and the other 3 numbers show the intensity level


Trigger mode switch

Change the trigger mode, refer to the manual for details


Serial port, female

RS232 communication interface with the PC


100 Mb Ethernet port

Ethernet communication interface with the PC


AC power input

100 - 240 V AC, 50/60 Hz


Intensity adjustment

Adjusts the intensity and width of the trigger pulse


Light connector

In total, four lights can be controlled individually


Trigger connector

For connection with an external trigger source such as a PLC, sensor or camera



Turns the controller on/off

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 - 240VAC 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.

Trigger Port and Setup

The trigger mode of this type of controllers is level trigger.

So the trigger mode can be achieved by high voltage trigger, low voltage trigger, rising edge trigger and falling edge trigger.

And the connection COM port is the same in the controller. 

The high power trigger (input voltage range is 5V to 24V) and low power trigger (input voltage range is 0V-2V) is separated by the dual opto-couple inside. 

For the rising edge trigger and falling edge trigger, normally the delivered item is rising edge trigger.

But it can be adjusted to falling edge trigger by the trigger switch key on the panel.

Normal trigger mode

Set parameter 1 in DEMO software or turn connector 1 OFF and turn connector 2 ON, 

the controller turns to normal trigger mode and intensity can be adjusted from level 0 to 255, 

the wide of trigger pulse can be adjusted from 1 to 999ms and it can be set through DEMO software or intensity switch key.

High intensity trigger mode

Set parameter 2 in DEMO software or turn connector 1 and 2 OFF at the same time,

the controller turns to high intensity trigger mode and one channel deliveries 1A. 

Trigger delay time can be adjusted from 0.01 to 5.00ms and it can be set through DEMO software or intensity switch key.

Sequence Diagram


T1 is the trigger delay time while T2 is the width of the trigger pulse.

Normal trigger mode: T1 80 μs; T2 can be set from 1 to 999 ms. 

High intensity trigger mode: T1 80 μs; T2 can be set from 0.01 to 5.00 ms.
