fixed bug can't remember energy data when power off.
you can download by bootloader.exe tool by RS485.
ARM BIN file download:

.zip   N10203060_KU_V20_260324SP.zip (Size: 14.42 KB / Downloads: 5)

bootloader.exe tool: 
[Image: zip.png]   KC868 Controller Bootloader.zip 
[Image: attachment.php?aid=8891]   
1. set baud rate=38400bps.
2. open com port.
3. power on Nx board, during LED fast blink when the "bootloader Detect" button right now. Then board will go to bootloader mode.
4. open BIN file
5. press "Download" button, begin download firmware, after finished, press "Run" button, ARM CPU begin work.

  replace resistance for COLB switch analog input from 0-5v signal to 4-20mA
Posted by: admin - 03-24-2026, 02:07 AM - Forum: KC868-HxB series Smart Controller - No Replies

For KC868-COLB customization, to change the 16 channels from 0–5V input to 4–20mA input, the following two types of resistors need to be modified:

Replace (R63, R64, R65, R66, R67, R68, R69, R70, R79, R80, R81, R82, R83, R84, R85, R86) 10K resistors with 150R resistors in 1206 package.

Replace (R57, R58, R59, R60, R61, R62, R55, R56, R71, R72, R73, R74, R75, R76, R77, R78) 5.1K resistors with 0 ohm resistors in 0603 package.
