Description
The National Instruments USB-232/4 Serial Interface Device, with Part Number 778473-04, is a versatile connectivity solution with four serial ports to accommodate multiple devices. Each port connects via a DB-9 male connector, and the device interfaces with computers through a USB 2.0 B-type plug. It’s a bus-powered device, drawing power directly from the USB serial bus, thereby eliminating the need for an external power source.
Designed primarily for Microsoft Windows operating systems, this device can operate in either DCE or DTE mode, which is selectable through software, providing flexibility for various communication requirements. It has a modest current draw of approximately 300 mA, which can reach up to 500 mA at +5 VDC when needed.
The USB-232/4 is lightweight, at just 0.83 pounds, and its compact dimensions of 8.3 x 4.9 x 1.4 inches make it suitable for various working environments. It is designed to operate within a temperature range of 0 to 70 °C and can be stored in temperatures ranging from –40 to 85 °C. The device’s operating and storage humidity ranges are 10% to 90% RH and 5% to 95% RH respectively, both non-condensing, ensuring reliability across various environments.
