NI enables serial to USB connection
Austin, TX - Engineers and scientists can connect existing serial instruments to USB with two new converters from National Instruments . The products, named NI USB-232 and NI USB-485, transform a USB port into asynchronous serial ports.
The NI USB-232 converter uses the RS-232 Serial protocol and the NI USB-485 converter uses the RS-485 or RS-422 serial protocols. Both converters are available in two or four-port configurations. They feature data throughput of up to 230.4 kb/s (NI USB-232) and up to 460.8 kb/s (NI USB-485) and can communicate with up to 31 devices. They comply with USB Specification 2.0. Products include serial driver software for Microsoft Windows 2000 and XP.
