Parameters   

Control panel specification < LTS-3STU48200-4 >    
Connection step:
Step 1: connected the light and controller (Reference to the picture on the right).
Step 2: external trigger signal connected to external trigger signal input interface of controller, camera synchronous trigger signal connected to camera synchronous trigger signal interface of controller, when need to trigger camera.
Step 3: If need to control the luminance by PC, please connect the PC with controller by RS232 data line in the power off status, then control by our demo program or the program you write yourself. Can set-up the each channel parameter manual when operated by serial port mode. That’s to say, the upper computer and controller all can set-up the parameter.
Step 4: connect power (AC100-240V 1.5A), press the red switch “-”, indicator light up, “o” uplifted, power on.

Mode set-up


Input wire connection method of the external trigger signal

3STU series controller can set-up rising edge trigger / failling edge trigger, LTS-3STU48200-4 have 4 trigger interface, each with + - , input (5-24V) high level between + -, trigger function can be realized.

Remark: TR1 (+1-) trigger CH1, TR12(+2-) trigger CH2, TR3 (+3-) trigger CH3, TR4 (+4-) trigger CH4.

Wire connection method of camera synchronous trigger signal
3STU series controller have 4 sets 12V camera trigger signal, synchronous with the output light, used for camera trigger, can trigger the camera shooting while the light on.

Remark: CAM1 and CH1 output synchronously, CAM2 and CH2 output synchronously, CAM1 and CH1 output synchronously, CAM2 and CH2 output synchronously.

The controller get the external trigger signal, then delay time T1≤2us, the light on. The lighting time is the set-up time on the controller panel, T5 on the sequence chart, T5≤999us. To send a signal to trigger the camera or external device after T2≤2us delay time of the light on. The camera can delay T3≤30us to shoot, the photos on this moment have highest luminance. Light off after camera shoot over and the light lightening time constantly T5, then the one working period was accomplished. The twice trigger time interval is more than 1.42ms.
