Description
The National Instruments USB-232/2 Serial Interface Device, with Part Number 778473-02, is designed to provide a robust 2-Port Serial Interface via a USB (Universal Serial Bus) connection to a PC, making it highly compatible with Microsoft Windows operating systems.
This device supports both DCE and DTE transceiver modes with automatic detection, eliminating the need for manual switching. It is conveniently bus-powered, requiring no internal batteries or external power supply, which simplifies setup and operation.
The inclusion of an integrated USB type-B cable with 2 D-SUB 9-pin male connectors ensures easy connectivity to a wide range of RS232 devices. The device also features TX and RX LEDs that serve as helpful indicators for data transmission and reception.
Operating at a maximum baud rate of 230.4 kb/s and a typical operating current of 200 mA at +5 VDC, the USB-232/2 is housed in a durable hard-plastic case with a metal baseplate, enabling it to withstand harsh working environments with operating temperatures ranging from 0 to 70 °C and relative humidity levels from 10% to 90% (non-condensing).
