Appendix I FAQ
☺
Why 24 series device does not have an erase function
◼
The device is based on EEPROM technology, device data can be directly rewritten without pre-
erasing, so there is no erase operation available.
◼
If you want to clear the device data, please write FFH data directly to the device.
☺
What is the reason for the software prompt device initialization error?
When programming some devices (such as 24 series devices), the programmer will perform initialization
detection on the device. The error will be prompted if the detection fails. Device initialization errors usually
have the following reasons:
◼
The device is not placed on ZIF Socket, or the device pins are not in contact.
◼
Device placement direction or position error
◼
There is a problem with the device itself
◼
The device mode does not match (the model selected in the software is different from the actual
placement on the lock seat)
◼
ISP connection line problem (ISP mode only, device with [ISP] suffix)
☺
Why the programmed device cannot work properly?
The programmed device does not work properly for the following reasons:
◼
The data file was not loaded correctly before the device was programmed
◼
There is a problem with the data file itself
◼
Programming operation steps are wrong
◼
Device working circuit / voltage problem
☺
Is it possible to program devices which have already been welded on circuit board through wires
from ZIF socket?
No.
The ZIF Socket is only used to place the device to be programmed (including IC socket). It is forbidden
to operate the device soldered on the circuit board through wires from ZIF socket. The peripheral circuit
on the board will cause the operation to fail and result in permanent damage to the programmer hardware.
Manufacturer is not responsible for any consequences that may result from this incorrect operation. The
EMI method is recommended for the device that has been soldered. Please refer to "Chapter 5 ISP
Program".

Can img file be programming?
The file encoding format supported by the programmer software is binary and hexadecimal (Inter HEX),
the binary file is suffixed with *.bin, and the hex file is suffixed with *.hex.
Img is just a file suffix, does not represent the file encoding format, usually (90% or more) such files are
binary coded, can be loaded directly in the software. The software automatically recognizes whether the
file is binary encoded and loads it in the recognized format.
In order to ensure the accuracy of file loading, we recommend that users check the buffer checksum and
file checksum with the engineering technician (or file code provider/customer, etc.) after loading such files.
The information will be displayed below the main window of program software).
