USB-RS422-PCBA

The USB-RS422-PCBA is a USB to RS422 level serial UART converter PCB. It incorporates 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-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.
