General Description
The LC-18-4CH-KP1 controller provides intensity control of LED lightings for machine vision
applications. The controller consists of 4 channels with individual settings for each channel.
There are 3 modes of operation provided to support different types of application. This
controller has built in display and keypads for manual control.

Operation Mode
Constant Mode
Constant mode offers continuous lighting intensity control. Lighting intensity is controlled
using constant current technique. Brightness can be adjusted from fully off to fully on in the
range of 0 –255.
Strobe Mode
Strobe mode provides short interval triggering for applications that require high intensity and
high precision. An input trigger signal will turn on the lighting output based on pre-set delay
and duration parameters.
There are 4 adjustable strobe parameters available:
Strobe Delay = Delay time between the external input signal and the lighting output
Strobe Width = Duration of the lighting’s turn on time
Output Delay = Delay time between the external input signal and the external output signal
Output Width = Duration of the external output signal’s turn on time
Parameter timings are in the range of 0-9999 which is equivalent to 0-99.99ms (in step of 10us)

Trigger Mode
Trigger mode provides most flexibility for variable timing light output. The light output ON
when input trigger signal received and OFF when no input signal.
Current Multiplier
Current Multiplier setting provides more precise control of lighting intensity for lightings with
different current ratings.
Current Multiplier setting range = 1-10
1 = 10% of max output current (100mA)
2 = 20% of max output current (200mA)
3 = 30% of max output current (300mA)
4 = 40% of max output current (400mA)
5 = 50% of max output current (500mA)
6 = 60% of max output current (600mA)
7 = 70% of max output current (700mA)
8 = 80% of max output current (800mA)
9 = 90% of max output current (900mA)
10 = 100% of max output current (1000mA/1A)
For example: if the lighting’s current rating is 260mA, current multiplier can be set to 3, setting
the maximum output current to 300mA. So the lighting’s intensity can be adjusted from low to
high within the range of 0-255.
If multiplier is set too high, for example 10 (100% of max output = 1A), the adjustable intensity
range for the lighting is only about 0-67. Setting the intensity value to 68 or higher will not
have any effect towards the lighting output brightness.

Control Mode
The LC-18-4CH-KP1 lighting controller can be controlled using either the display panel or
external control (RS232/USB/TCPIP), but both controls cannot be used at the same time.
The LED labeled “EXT” is an indicator of which control is in use:
1) LED turned on –External control (USB/RS232/TCPIP)
2) LED turned off –Display Panel control
Switching the mode
To switch the control mode, hold down UP and DOWN button for about 1 second and observe
the change on the LED indicator.

Input Signal
Input signal is used to turn on the lighting under Strobe/Trigger mode.
The lighting output is turned on after a delay time defined by Strobe Delay, while the turn on
duration is defined by Strobe Width.
Acceptable voltage for external input signal is from 3.3-24VDC.
The external trigger signal can be configured as rising edge or falling edge trigger.
Output Signal
The output signal is optional and is used to trigger external devices such as smart camera. The
output signal is only available in Strobe Mode.
The output pulse is triggered after a delay time defined by Output Delay, while the turn on
duration is defined by Output Width.
