HMI display control

[Maq17444]

Hi, 

I'm interesting in controlling all (KC868-H32BS and KC868-E16s etc.) relay's by not only home assistant but with a robust HMI monitor for more reliability and customization; recently I bought KC868-E16s and I noticed that it has a 4 pin Serial interface Rx Tx... which mean that I can control it by UART with the proper HMI display, but also I have a KC868-H32BS & KC868-colb and wondered that could I control it by the HMI by RS485/ RS232 as Master 'if applicable' or there are other ways.


Moreover, I've found the datasheet of the kc868' RS485 protocol but not for RS232!


Note: I'm not an expert in serial communication field.


Thanks

1. KC868-H32BS and KC868-COLB serial port not use for HMI display. KC868-E and KC868-A series board mainly use for DIY, so all hardware resource is open. if you want KC868-H32BS and KC868-COLB work with HMI display. there is a way. let KC868-H32BS and KC868-COLB's RS232 or RS485 connect to KC868-A series board, HMI connect with kc868-A series board. then write arduino IDE code for HMI device and control H32BS and COLB. just use a third board work as a bridge.

2. RS232 protocol at here link: https://www.kincony.com/smart-controller...tocol.html
RS232 protocol as same as network's protocol, just use 115200bps baud rate.
