Advanced users • Talking RS485 over UART on the raspberry pi 5

I've been unable to get a RS-485 transceiver to work from the Raspberry Pi 5 UARTs. The comm works using a USB to RS485 cable. The UART pins are functioning properly. They were tested with a working serial device. I can get the RX and TX to blink once then nothing. Anyone know the magic goo to get this working. So far i have tried a DSD TECH SH-U12 RS485 to TTL 5V Board with MAX13487 and a KNACRO TTL to RS485 Module 485 to Serial UART.

Any help or point me in a direction would be greatly appreciated.
Thanks.
