Orange PI + Max485

Dzo

Good day, mates.I have a trouble connection MAX485 board to Orange Pi Pc Plus (H3). UART works as exprected with below config set in the script.bin

[UART1]
uart_used = 1
uart_port = 1
uart_type = 2
uart_tx = port:PG06<2><1><default><default>
uart_rx = port:PG07<2><1><default><default>
uart_rts = port:PG08<2><1><default><default>
uart_cts = port:PG09<2><1><default><default>

However if I connect Rs485 board
RX - RO
TX - DI
CTS - DE
RTS - RE
it doesn't work.

I have tried to change uart_type and replace CTS-RTS pins but it desn't help.
What I do wrong? Thanks in advance.
