RS422 Interface

I divided up the RS422 and RS485 interfaces into their own pages. So the orignal page address lists only RS422 informantion; RS422.

The new page address for RS485 information is here; RS485

RS422 [EIA422] defines a differential interface using a single, unidirectional driver with up tp 32 receivers. The RS-422 interface will support Point-to-Point, and Multi-Drop circuits.

RS485 [EIA-485] specifies a bidirectional, half-duplex data transmission. Up to 32 transmitters and 32 receivers may be interconnected in any combination, including one driver and multiple receivers (multi-drop), or one receiver and multiple drivers.
