What is a USB RS422 PCB?

1 Description The USB-RS422-PCB is a USB to RS422 level serial UART converter PCB incorporating FTDI’s FT232RQ USB to Serial UART interface IC device which handles all the USB signalling and protocols. The PCB provides a fast, simple way to connect devices with a RS422 interface to USB.

Can Rs 422 be used in 485 circuits?

RS-422 will support Point-to-Point, and Multi-Drop circuits, but not Multi-Point [EIA485]. EIA-485 devices may be used in 422 circuits, but EIA-422 may not be used in 485 circuits (because of the lack of an Enable line).

What is eia422 interface circuit?

EIA/TIA-422 Interface Circuit. EIA/TIA-422 defines a Balanced (differential) interface; specifying a single, unidirectional driver with multiple receivers (up to 32). RS-422 will support Point-to-Point, and Multi-Drop circuits, but not Multi-Point [EIA485].

Does RS-422 support point-to-point and multi-point circuits?

RS-422 will support Point-to-Point, and Multi-Drop circuits, but not Multi-Point [ EIA485 ]. EIA-485 devices may be used in 422 circuits, but EIA-422 may not be used in 485 circuits (because of the lack of an Enable line).
