USB to PCB FTDI RS422 UART Converter
TThe USB-RS422-PCBA is an USB to RS485 level serial UART converter PCB incorporating FT232RQ USB to serial UART interface IC device. The FT232RQ handles all the USB signalling and protocols.

Specifications Top

The PCB provides a fast, simple way to connect devices with a RS422 interface to USB. Each USB-RS422-PCBA 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. This feature can be used to create a security or password protected file transfer access using the PCB. The USB-RS422-PCBA requires USB drivers which are used to make the FT232R on the PCB appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port.
