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 an 100 - 240 V AC power source and of switch the controller on. 

            The digital display is lit. If the intensity 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 controller is level trigger, so the trigger mode can be achieved by rising edge trigger and falling edge trigger. There are 4 

trigger channels: 4 connectors for Trigger +, and "COM" is the common interface of Trigger -.

The high voltage level (input voltage range is 5V to 24V) and low voltage level (input voltage range is 0V-2V) is seperated by the dual optocoupler inside. 

Default trigger mode is rising edge trigger, but it can be adjusted to falling edge trigger by the trigger switch key on the panel.

Normal trigger mode

Turn Ts1 into OFF and turn Ts2 into ON, the controller turns to normal trigger mode and intensity can be adjusted from 0 to 255 level.

The width of trigger pulse can be adjusted from 1 to 99.9ms and it can be set through DEMO software or intensity adjustment key.

High intensity trigger mode

Turn Ts1 and Ts2 into OFF at the same time, the controller turns to high intensity trigger mode and one channel outputs 1A.

The width of trigger pulse can be adjusted from 0.01 to 5.00ms and it can be set through DEMO software or intensity switch key.

Sequence diagram

Description

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