USB-232 / USB-485 Series Serial Instrument Control Interfaces

MODEL:

USB‑485/2 (2-Port)

USB‑485/4 (4-Port)

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.

4-Port, USB, RS485/RS422 Serial Interface Device The USB‑485/4 interface transforms your USB port into a single asynchronous serial port for communication with RS485 and RS422 devices. You can use a USB‑485/4 port as a standard serial port from your application, including RTS/CTS hardware handshake lines. NI serial interfaces also appear as standard COM ports for compatibility with programs that use serial communications.
