Connect CMT6002 Writer to PC The accessories of the CMT6002 Writer include a CMT6002 Writer motherboard, an optional TypeAB USB cable and 9 V / 1 A (or 7.5 V / 1 A) DC power supply (the DC plug polarity is center positive and outer negative) as shown in the below figure. -
Page 5: Online Programming Operation
Figure 4. Writer Tool Set (the USB cable and DC power supply are optional) Connect the CMT6002 Writer motherboard and the host computer via a USB cable. When connecting the Writer for the first time, the computer installs the CMT6002 Writer USB driver automatically. An installation window will pop up during the installation. - Page 6 If the packaging options cannot be selected, it means the steps are not in the correct order. Please check and connect the USB cable to the computer first and then open the CMT6002 Writer software. Figure 6. Select Chip Models After the device selection is confirmed, the Load Flash window pops up to load the program file to be burnt as shown in the below figure.
- Page 7 The software UI screen as shown in the below figure displays after the Flash file and the EEPROM file are loaded. At this point, the files to be programmed has been loaded into the permanent memory of the CMT6002 Writer board. It will not be lost due to power loss unless a new file to be programmed is loaded.
- Page 8 CMT2189C, please do not check the Test frequency option, as these models do not support the frequency test function.
