Control panel specification< LTS-2DPA24200-2S >
Step 1: Connect the light to the controller (refer to picture 2.1).
Step 2:If external trigger control is required, connect the external trigger to the controller trigger port.
Step 3: Connect power (AC 100-240V 50/60Hz), press the red switch”-”, indicator light up, “O” uplifted, power on.
Step 4: If need to control the luminance by PC, please connect the PC with controller by RS232 data cable or network cable 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 or LAN port mode. That’s to say, the upper computer and controller all can set-up the parameter, no need mode swapping.

Trigger port set-up
This series controller is high level trigger. LTS-2DPA24200-2S has a total of 4 trigger signal input ports, representing 2 channels. Each channel has + and -identifiers, and high level 5-24V is input at + and -ports to achieve triggering function.
Trigger inspection: when the controller is in the normal on mode (MANU mode), input high level 5-24V at the trigger port, and the light source is off. When the controller is in normal off mode (REMO mode), input high level 5-24V at the trigger port, and the light source is on.
Common wiring methods of external trigger signals
Normal on mode (MANU mode):
Input high level 5-24V at the trigger port, and the light source is off.
Normal off mode (REMO mode):
Input high level 5-24V at the trigger port, and the light source is on.
Specification: T1 is trigger delay, T1≤30us，T3≤30us.
