Product Description

Each USB-RS422-PCB contains a small internal electronic circuit board, utilizing 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.
