Hello Eric,
The AWR1642 does not support direct interface with transceiver. But we do have a UART interface. So you could look at using a RS485 to UART converter. We have not used this before but you could look at this - www.amazon.com/.../B01ILVNU7E

Hi Vivek:

As I know, AWR1642 have UART interface that should be connect to RS485 transceiver, such as SN65HVD178xA-Q1.

May I know why can't support through AWR1642?

Thanks.

Regards,

Eric

Hello Eric,
I am not very familiar with the RS485 protocol , but the RS485 transceiver have an additional direction control which is inherently not part of the UART interface. Suggest you can check on the SN65HVD1780 E2E forum for the protocol handling to interface to standard UART interface (e2e.ti.com/.../addpost ?

Vivek
