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.
Each USB-RS422-PCB contains a small internal electronic
circuit board, utilising the
FT232R plus a USB type-A connector. The
integrated electronics also include an RS422 transceiver plus Tx and Rx
LEDs which give a visual indication of UART traffic.
The PCB is USB powered and USB
2.0 full speed compatible. Each PCB supports a
data transfer rate up to 3 Mbaud and supports
the
FTDIChip-ID™,
with a unique USB serial number programmed into
the
FT232R. This feature can be used to create a
security or password protected file transfer
access using the PCB.
