2.2 Rolling Code Settings
The CMT6002 Writer provides the ability to program Rolling Code which is stored in the EEPROM area. If a user's application
requires Rolling Code, click Rolling Code button, a window pops up as shown in the below figure. An example is shown in the
below figure with the following configurations: the starting Rolling Code address in the EEPROM area is 0xfe; Rolling Code takes
up one byte; the start value of Rolling Code is 0x01; the Rolling Code increases by 1; the end value is 0xff. When the Rolling
Code is increased to the end value, it cannot perform offline programming of the Rolling code any more. It needs the host
computer to have setup again. When Disable End Value is checked, the scrolling code programming will start again from the
initial value when it is programmed reaching the maximum value.

Once set ready, click OK to confirm, then the message of the Auto Program Mode changes to Flash + EE + R_Code, indicating
that the Rolling Code is set successfully as shown in the red rectangle in the below figure.
Figure 19. Rolling Code Setup Successful Message
If users program the Rolling Code further when the Rolling Code reaches the maximum value, the writer will report an error and
prompt the message shown in the below figure. At this point, the Rolling Code needs to be reset by the host computer before any
further Rolling Code programming.

2.3 Programming Limit Function
The CMT6002 Writer provides the programming limit function. Click Setting button in Pass Count area to set the initial value and
maximum value of the Pass Count as shown in the below figure. When Max Value is set to 0, the number of programming is not
limited, and Max is displayed as Disable. Each time an IC is successfully programmed, it adds 1 to Pass (displayed in Pass Count
area). When Pass reaching the Max Value, the writer will no longer respond further programming commands. At this time, it
needs the host computer to update Pass Count to continue programming.
Figure 21. Pass Count Settings
2.4 Frequency Calibration and Test Function
The CMT6002 Writer provides frequency calibration function for the internal high-frequency RC oscillator of the MCU. The RC
oscillation frequency has been calibrated within 1% error range in factory. If users need to perform the frequency calibration
function, the check box for Calibration frequency should be checked as shown in the below figure. When the frequency
calibration function is selected, the message of the Auto Program Mode area changes to Flash + EE + R_Code + CAL_Freq,
indicating that the frequency calibration function is set successfully, as shown in the following figure.
Note: CMT2189B and CMT2189C do not support the frequency test function. Do not check the Test frequency option in
programming settings.

3 Offline Programming Operation
3.1 Download Program to Be Burnt
1. Connect the writer to the computer via USB.
2. Open the programming software to download the program file and EEPROM file to the writer and record the
CheckSum value. Please refer to Chapter 2.1 for more details. Disconnect the writer and the computer. When
power-on the writer again, it will reset and enter the offline mode automatically. Check whether the CheckSum value
in the LCD scrolling information (Figure 23) and the one in the downloaded program (Figure 24) are the same.

3.2 Chip Offline Programming
After downloading the program or EEPROM file to the writer, place the chip correctly, then users can perform offline programming
and other operations.
After the CMT6002 Writer is powered on, the following information is displayed cyclically.
1. Chip model (see Figure 25).
2. The UID, which displays the rolling code for the next rolling code programming operation. If the rolling code function is not
enabled, no such information is displayed.
3. Program name and programming mode (see Figure 26).
4. FLAID and EEID, which is the CheckSum information (See Figure 27).
5. PASS NUM, which is the number of successful programming (See Figure 28).

Make sure the programming mode of the writer is the same as that selected when downloading the files from the host computer.
Press the programming button to perform the programming operation. When the programming succeeds, the green light turns on,
and the screen displays the programming success message. If the programming fails, the screen displays an error message and
the red light turns on along with buzzer alarming.
The CMT6002 Writer supports Rolling Code programming. Just start the Rolling Code function and set the related parameters
such as Rolling Code Value when downloading the files to be programmed to the writer. Please see Chapter 2.2 for more details.
Each time a chip is programmed, the Rolling Code for the next programming operation is displayed. If the programming fails, the
value of Rolling Code will remain unchanged. Once the programming succeeds, the value of Rolling Code will change in the next
programming operation.
The CMT6002 Writer supports the maximum programming number settings, which requires to set on the programming limit
function when downloading the program files to the writer. Please see Chapter 2.3 for more details. Each time chip programming
completes, it will display the current Pass Count value. If the programming fails, the value of Pass Count will remain unchanged.
Once the programming succeeds, the value of Pass Count will be increased by 1 automatically. When the Pass Count reaches
the maximum setting number, the writer will no longer respond to any offline programming command with the screen information
displayed as shown in the below figure. At this time, users need to connect the host computer to update the Pass Count to
continue offline programming.

3.3 CheckSum Reading Function
For checking the correctness of the program burning, the Writer provides the function of reading the chip CheckSum. Make
sure the chip is placed and connected correctly, press the KEY_MODE button shortly, the LCD will display the CheckSum of the
chip (See the below figure).
