The iCAT LED analyser supports the USB, I2C, and RS232 interfaces.

USB interface:

When using the USB port, you need to install the USB driver, and the driver can download from our

company's website. After you install the driver, USB will be virtual into serial port, and its port number

can be changed as required. When communicating with the USB port, the analyser will not require an

external power supply, and will preferentially use the power supply on the USB as the power supply. USB

supports multiple operating systems such as Windows, Linux, Android, MAC, OS, and so on.

After connecting to the PC, the system will prompt the driver installation (the download link of driver:

http://www.icatprog.com/col.jsp?id=125), after you install the driver, you can see the USB Serial Port

project on the computer management, and this is the iCAT device.

RS232 interface:

The default supported arguments parameter is 19200 baud, 8 data bits, and 1 stop bit, there is no parity,

when using RS232 as a communication interface, please use the 9PIN serial port to connect line

equivalence (there is no need to exchange RX and TX signals), at the same time to provide the external

power supply to the iCAT LED analyser.

To connect through the RS232 interface, you only need to use RXD and TXD signals. Because the iCAT

has already made the signal connection in the interior, so the connection line just needs to use the direct

connection serial port signal line, does not need to make the intersection.

Note that the serial baud rate is 19200

The commands of serial port transmission need to take carriage return (16 hexadecimal number 0D) as

end mark, iCAT returns information take \n (16 decimal number 0A) as the end mark.

For PLC devices that cannot send ASCII characters, you can directly send 16 hexadecimal number, and

translate the characters of the commands directly into the corresponding 16 hexadecimal number. For

example, the Get sn command: Send 67 65 74 20 73 6E 0D, iCAT return 25457272 6F 72 0A

I2C interface:

iCAT LED analyser can be connected to any I2C master controller from a device as a I2C, and the iCAT

LED analyser can be easily integrated with controllers such as the MCU class using this interface. Before

communication need to use the SetAddr command to set the I2C address of the device in the use of I2C

interface and iCAT LED analyser.

Chapter2 LED color and brightness analysis

1.LED color test

The iCAT LED analyser supports a variety of formats to represent colors, including RGB, Hue, Saturation,

CIE1931 xy and wavelength,etc. Each representation can be expressed in color.

1.1 Hue and Saturation

Hue uses 360 degrees to represent colors. Hue uses a degree value to represent the color value of RGB,

which is the most convenient in LED color testing. For example, the red Hue value is near 0 degrees, the

green Hue value is near 120 degrees, and the blue Hue value is near 240 degrees. As shown in the

following figure:

Saturation indicates the purity of color, the boundary of the Hue circle indicates saturation of 1, and the

center of the circle represents the saturation value of 0. the Saturation value is higher that indicates the

color is more pure. Pure color saturation value of 1. Pure white saturation is 0.

Usually, using two parameters of Hue and Saturation can determine the color of a LED, which is

recommended by the LED test parameters.

1.2 CIE1931 xy chromaticity

CIE is short for the Conseil International de Illumination. CIE formulated a range of colorimetric

standards. Using color coordinate of xy to determine the color in the 2D coordinates, the chromaticity

diagram is CIE1931 chromaticity diagram. For example the coordinates of a point in a chromaticity

diagram is x=0.4832, y=0.3045, then its color matches the color of red apple. The white xy value

coordinate is (0.33,0.33); the color surrounding the edge of the color space is spectral color, the maximum

saturation boundary represents the spectral color, and the number on the boundary indicates the

wavelength of the spectral color, and the outline contains all the perceived tones. As its shown in the



16

following figure:

1.3 White LED Test

For ordinary LED testing, we usually use the color and brightness ways to test, but the white LED

test is different from the ordinary LED test. White is not a kind color, white is the color of a mix of all

colors. When the three colors of R, G, and B are mixed in a similar proportion, they appear white color.

When testing white LED, saturation must be used. The value of saturation is between 0% and 100%.

When the saturation is 0%, it is expressed as pure white, and 100% is expressed as pure other colors.

In the actual test, white saturation values are usually changes in the range of 30%. The white saturation

value is the purity of white, saturation values closer to 0 represent more pure white. However, the specific

value should be determined according to the actual white LED test value.

Most LED manufacturers use the chromaticity of x,y coordinate values to identify the white LED, the x,y

coordinate values between 0 and 1. The x, y coordinates of white LED at about 0.33,0.33. But the value is

not entirely certain. Because there are some white LED is cool tone, and there are some white LED is

warm tone.

When using iCAT LED analyser to test white LED, it is recommended to use saturation and x, y

chromaticity coordinate value to test as the criterion.

2.LED luminous intensity analysis

Intensity is used to test the test index of luminous intensity of LED. The iCAT LED analyser supports

multiple instruction outputs test LED value of Intensity, which consists of two commands, Get,

CHXX.HSI2, and Get CHXX.INT, and the command output is output in 0-99999 form. While retaining

the Get CHXX.HIS command, this command provides the output format of luminous intensity



17

percentage.

The LED Intensity test of the iCAT LED analyser is a relative value test. First, we need to study the

standard product and read the Intensity value of the standard products, then, according to this standard,

the upper and lower limits are set as test criteria.

The test value of Intensity can be affected by many factors. The following factors affect the final test

value.

◆The internal diameter of the used fiber. The internal diameter is greater that the light-guide quantity is

higher, and the test value of Intensity is greater.

◆The distance and angle of the fiber from the LED. The distance and angle of the fiber from the LED

will affect the import of light, which will affect the test value.

◆The influence of ambient light. The intensity of ambient light also affects the value of Intensity

◆A light emitting LED to around the test LED affects the accuracy of test LED test

◆Blinking LED

◆The selected work mode, the iCAT LED analyser supports different working modes and corresponding

parameters

◆The choice of different patterns, and the test results will be different

◆whether using an optical fiber connector

In order to ensure the stability of test, recommend the use of iCAT optical fiber connector. The test as

shown in the following figure:



18

3.The work mode and setting of the iCAT LED analyser

For different luminous intensity LED test, iCAT LED analyser provides 3 initial settings of standard light

source, bright light, weak light,etc. Setting command format is: SetDefault XX. XX is 01,02,03. The

corresponding initial values of each parameter are as follows:

XX

value

Light source Gain Intetime x y wavelength Intensity

01 Standard light source 16X 100ms 0.000 0.000 000 00000

02 Bright light 1X 25ms 0.000 0.000 000 00000

03 Weak light 60X 200ms 0.000 0.000 000 00000

Among them, Gain is gain times, Intetime is the sensor integration time. The iCAT LED analyser

provides 4 gain multiples that can be set to the gain multiples of the specified channel by a separate set

command. The corresponding relation and setting commands are as follows:

Gain times Set command Corresponds to the value of X

1X Set CH##.Gain=X 1




iCAT LED analyser provides 5 kinds of sensor Intetime. Similarly, you can set the intetime of the

specified channel by a separate set command. The corresponding relation and setting commands are as

follows:

Intetime Set command Corresponds to the value of X

25ms Set CH##.Intetime=X 1







19

Chapter3 iCAT LED analyser command format

1. Command format

The command of iCAT LED analyser is no need to case sensitive, and% represents output in the

command format. At the same time also need to pay attention to the blank in the command.

If the command format is wrong, the iCAT LED analyser will return to %Error. If the format is correct,

the corresponding value is returned. It is recommended to use the iCAT XP tools in the input command.

the Terminal page of ICAT XP supports command debug mode. As shown in the following figure:

You can also use the serial port tool for debugging commands, due to the iCAT LED analyser needs to use

the carriage return as end of command, so the serial tools need to support this setting, we recommend the

use of UartAsssist as a debugging tool, the tool can be downloaded in http://www.icatprog.com/col.jsp?

Id=125 page. When using the UartAsssist for command debugging, need to the following settings

For users who use PLC or microcontroller, the string command may need to be converted into sixteen

hexadecimal. The following table for converting all of the above commands, users can follow each

command detailed and ASCII code character comparison table. Note that each command ends with

carriage return (16 hexadecimal number 0D), iCAT returns the message with the newline character (16

hexadecimal number 0A) as the end mark. Because the string command is not case sensitive, so pay

attention to the corresponding ASCII code in convert to 16 hexadecimal. The red characters in the

following table represent variable parameters.

Chapter4 Multiple devices parallel use

When need to test a larger number of LED at the same time, it need to use parallel use for iCAT, iCAT

supports up to 256 devices in parallel, if all 16 channel models are used, at most to support 4096 LEDs

for testing at the same time, It is suggested that the iCAT be paralleled in two ways, one way is to connect

through multiple USB ports, and if the master side such as PC is not enough, USB Hub can be used to

extend the USB port. The second is use the I2C port to connect, connect multiple iCAT devices via the

I2C bus.

1.USB connection schematic diagram

2.Multiple devices in parallel through I2C bus

If you use PC, you can use USB transfer I2C control card to expand the I2C master controller. To connect

in parallel through I2C, you need to set the I2C address of the LED analyser.

Chapter6 Installation of iCAT LED analyser

iCAT LED analyser consists of analyser, fiber optic cables, fiber optic connectors, and USB data lines.

Installation and notice of the LED analyser are as follows:

1. First, insert the fiber line into the analyser, and the fiber line is inserted into the depth of the analyser to

be suitable for the 1 mm from the bottom, you can insert the fiber line at the bottom, and then pull it out

about 1 mm.

2. Tighten the fiber line after the fiber line is inserted.

3. The other end is inserted into the optical fiber joint line, note that plug the fiber line into the bottom of

the fiber connector and screw it down.

4. The optical fiber connector is fixed on the fixture, the fiber optic connector shall be 3-4 mm away from

the test LED, and the optical fiber connector is required to test LED.

Notes:

1. Using the optical fiber joint will be attenuated to light, so, for weak light LED, try not to use the fiber

optic connector.

2. When insert the fiber line into the LED analyser, don't plug the fiber in the end. It's better to leave the

fiber line about 1 millimeter from the bottom of the analyser.

3. The accuracy of testing is closely related to the installation, and consistency should be maintained

during installation.

Chapter7 LED analysis using the iCAT LED analyser

Automatic test LED color and intensity completed by the iCAT LED analyser mainly in two ways, one is

to read the values directly in the command mode, and then the upper computer judges the test result

according to the reading value. The other one is to create a test project using iCAT TestProgram on the

Windows platform, and then execute the project using the iCATComm command line tool, and

iCATComm will directly output the test results.

1.THE WAY TO READ TEST RESULTS DIRECTLY WITH COMMANDS

(1) Read the test value of the testing LED using the read command. It is recommended that Hue and

saturation be used as the criteria for color determination, Intensity is used as the criterion for the Intensity

of LED. Read the value of HSI, using the Get CHXX.HSI command, you can also read the test values of

all channels of the analyser at once with the Get HSI.All command.

(2) The upper computer judges the value of the read HSI to determine whether the LED color and

Intensity in the preset range.

2.USE THE SOFTWARE TOOLS PROVIDED BY ICAT TO COMPLETE THE TEST

iCAT LED analyser provides a complete set of supporting software that allows users to complete settings

and integration of the test software with the most simple way. Here's one of the easiest things to do.

For example：There are 3 LED on a PCBA need to test, there are two green LED (LED0, LED1) and one

is two colors LED (LED2), which is red and yellow. To complete the test automation test, the operating

system is Windows 10. The test step is to test whether LED0 and LED1 are green and its Intensity first,

then light the third LED to the red state, and test whether it is red and Intensity, then re-activate LED2 to

yellow, and test its color and Intensity.

Solution: Select the iCAT LED analyser of 4 channel. Software settings method are as follows:

Step 1: To generate the LED0, LED1 test file, named LED01.cat

Opening iCAT TestProgram. and select Project. (For more details on iCAT TestProgam, please refer to

<iCAT TestProgram User Guide>).

Then, as shown in the following figure:



46

Enter a project name of LED01.CAT, and then select the model of LED analyser, to select the

communication interface. Then select the test items. As shown in the following figure:

Test items generally recommend HUE, Saturation and Intensity. When you have chosen, click the Add

command button to enter the parameter setting interface. As shown in the following figure: If the iCAT

LED analyser has been connected, you can use the method of learning, otherwise manual setting will be

used.
