• Precaution when writing the data
- Consider two download jigs (PWA-DWNLD-350-JIG2) as “Download jig 0” and “Down load jig 2”
and do not mix them up when writing.
- Set the writing voltage (VID) to 3.3 V.
- When writing the data, set the address from 0 to 3FFFFF. The data may not be written correctly if
it is not set.
- The Flash ROM in which the data will be written, on the download jig is selected by switching the
rotary switch on the adapter. Be sure to switch the rotary switch on the adapter depending on the
data (file) to be written.
Note: Note:
Be sure not to confuse different ROM Versions since the file name is identical although the ROM
version is different.
