USB-485/2, USB-485/2 RS422, RS485 port converter

Producer: NI

Category: NI data acquisition equipment

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

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.

Features:

Compatible with Standard PC Serial Port
1, 2, and 4-Port Versions
Handle RTS/CTS Hardware Handshake Lines
128 B Transmit and Receive FIFOs
5,6,7, or 8 Data Bits

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.
