RS485 Full-Duplex Interface
The RS485 full-duplex interface is used for non-polled communication protocols in
point-to-point connections over longer distances than those acceptable for RS232
communications or in electrically noisy environments.
The following pins of the 9-pin connector are used for RS485 full-duplex interface
connection:
Pin Name Function
2 TX485 + RS485 output (+)
3 RX485 + RS485 input (+)
