Applicable Product Type:
RS-422/485 board

Relevant Information:
Generally, they are substituted as follows.
RxD- -> RDA
RxD+ -> RDB
TxD- -> SDA
TxD+ -> SDB

However, the above substitution for RDA RDB SDA SDB does not always apply.
We recommend that you check the circuit diagram of the device to which connection is made before establishing the connection.
