RS422 is a four wire interface and supports full duplex (both transmit and receive active at the same time)

RS485 is a two wire interface and therefore supports

the Transmit +ve and Receive +ve signals together and the Transmit

required to connect to

one device on the network to be the master and

Remember that by connecting the Transmit and Receive differential pairs together (as above) then when you

transmit you will effectively place the transmit data into your receive buffer! So you need to ensure that you

you look for data in your receive buffer.
