USB-RS485-PCBA

The USB-RS485-PCBA from FTDI is a USB to RS485 level serial UART converter PCB. It incorporate 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 RS485 interface to USB. USB-RS485-PCBA contains a small internal electronic circuit board, utilizing the FT232R plus a USB type A connector. The integrated electronics also include an RS485 transceiver plus Tx and Rx LEDs which give a visual indication of UART traffic. Each PCB supports a data transfer rate up to 3Mbaud 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. The USB-RS485-PCBA requires USB drivers which are used to make the FT232R on the PCB appear as a virtual COM port (VCP) and allows user to communicate with the USB interface via a standard PC serial emulation port.
