DB9-USB Family of UART Converter Modules Datasheet
■The DB9-USB Family of UART Converter Modules
▲The DB9-USB connector modules can be used to upgrade an RS232 port to an active USB port. In some cases, this can be done without the need to redesign the PCB. In some cases, they can reduce system costs by removing an RS232 level shifter from a design.
▲The DB9-USB family consist of 6 modules. Two of these operate at RS232 voltage levels – these can be used as a direct replacement in a system which uses RS232 levels, while four of them operate at digital voltage levels (a choice of 5V or 3.3V) – these can be used to interface to an application systems logic level which could result in the bill-of-materials being reduced by the removal of any RS232 level shifters which may be in the system. Each is available to replace either a male or a female DB9.
●Features
■Adds one USB serial port by connecting to the RS232 DB9 footprint of a device
■Easy placement for an standard Male and Female RS232 DB9 footprint of a device
■A selection of RS232, 3.3V or 5V UART signal levels.
■Works with USB 1.1 & 2.0 Host and Hub ports
■Industry Standard FTDI chip set & device drivers for maximum compatibility
■Microsoft Windows® WHQL-certified, Mac, Linux and Android drivers.
■Installs as a standard Windows COM port
■128 bytes transmit buffer, 256 bytes receive buffer
■UART data signals: TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI, GND
■Powered by USB port. No external power adapter required.
