National Instruments USB-232 / USB-485 Series Serial Instrument Control Interfaces for USB
Features
The National Instruments USB-232 / USB-485 Series Serial Instrument Control Interfaces for USB transform the user's Universal Serial Bus (USB) port into asynchronous serial ports for communication with serial devices. The NI USB-232 and USB-485 are available in either 1, 2, or 4-port versions and use standard RS-232, RS-422, or RS-485 communications. All products include driver software for Windows 2000/XP. One can install and use the USB-232 and USB-485 as standard serial ports from your existing applications or with applications written with NI-VISA.
Additionally, the USB-232 2 and 4-port versions feature software-selectable DTE or DCE transceiver modes, as well as an automatic transceiver detection mode, or Auto232. The USB-485 features software selectable biasing; therefore, you can turn biasing on and off for each port through software.
Development environments, such as Visual Basic, Visual C++, and Excel, as well as National Instruments LabVIEW, LabWindows/CVI and Measurement Studio, can access the serial ports using standard serial I/O functions.
