STM32 UART to RS485 Communication bit Shift Problem

Hi All

I have a problem with RS485 Communication. I am using STM32f103rbt6. Only send a struct data (13 bytes). Microcontroller send this data to ADM4855ARZ (RS485 IC). Data sends correctly ( ı checked with logic analyzer). Than this data goes RS485 to RS232 converter correctly. I can see this data on RS232 connector. A digitus rs232 to USB converter is connected to the RS232 connector and ı want to see this data on real term but data two bit left shifting. I changed digitus converter try another terminal try another code but result is same. How can ı solve this problem? Has anyone encountered this problem?

Thanks

I solved my problem. My RS485 to RS232 converter was broken. I fixed it.
