If controller software support it. I have seen two *.bin files for NIU, they look like encrypted, so can be flashed over CAN (NIU use RS485) bus only.

I am not really familiar with ultra edit and foc files. How did you open or convert the foc file to something readable? I only see strange symbols. £¥$¿•¡*£{}$??????

We have different settings or different versions of UltraEdit. My old UltraEdit-32 (v12.00) open *.foc file always in binary mode. Try open *.foc file, then "Edit"->HEX Functions->HEX Edit. You have to see something like:

00000000h: 31 32 33 34 35 36 37 38 39 70 72 66 0D 0A 06 07 ; 123456789prf...
...
...

Probably you will need switch to "Edit"->HEX Function->HEX Edit\EBCDIC and back to "Edit"->HEX Functions->HEX Edit. Or try use binary compare, you can do binary edit at result windows.

To binary compare two files use: "File"->Compare Files, select two files to compare, select "Compare Options" -> Binary, "Editor Tiling" -> Tile Vertical.

Thanks for your support. I will give my best!

I have opened the foc file and see all the lines. My problem is the part on the right side next to the semicolon. There I cannot see the parameters you have found. There are just strange letters. How did you convert them into the usable information you have posted? Especially the 0000h -0100h lines.

You don't need the third column, it a pure binary file without any comments and structure. At first assume it consist from 16 bit values (two bytes, left MSB and right LSB), then try to convert the value to decimal. Use Windows Calculator at programmer view. Select hexadecimal, select 2 bytes, enter value, then switch to decimal and write the value. Any value started from F (bit 16 = 1), for example FF 9C, most likely is negative, FF 9C = -100 If you did not get reasonable value, most likely it is 1 byte value, for example:
0106h: 6E : High-Speed Percent (110)
0107h: 43 : Middle-Speed Percent (67)
0108h: 3C : Low-Speed Percent (60)
0109h: 32 : Fourth-Speed Percent (50)
010Ah: 32 : Speed Limit Percent (50)
010Bh: 00 : ???

Respect! Thanks for your lesson in informatics.
