Description
The AT-DIO-32F, with part numbers 180735-01 and 776246-01, falls under the category of PC-based Digital I/O devices. This product is manufactured by National Instruments and is part of their AT Series. It features a 32-bit Digital I/O interface, designed to cater to a variety of digital input and output requirements.
This model boasts 32 I/O channels, which are organized into four 8-bit ports, providing flexible connection options. It is compatible with TTL (Transistor-Transistor Logic), ensuring it can work with a wide range of digital logic levels. The AT-DIO-32F is capable of a data transfer rate of up to 450 kwords/sec, making it suitable for high-speed data acquisition and control applications.
One of the key features of the AT-DIO-32F is its interrupt handling capability, supported by onboard counters. This allows for efficient management of I/O operations without overburdening the CPU. Additionally, it offers two DMA (Direct Memory Access) channels, enabling rapid data transfer between the card and system memory, bypassing the CPU to save processing time.
The device also provides multiple handshaking options, facilitating versatile communication protocols with external devices. It includes an RTSI (Real-Time System Integration) bus interface, ensuring easy integration with other compatible devices for expanded system functionality. For physical connections, it uses a 50-pin male connector.
Compatibility is a strong suit of the AT-DIO-32F, as it can be used with a variety of systems including IBM PC/XT, PC AT, Apple Macintosh II, Q-BUS system, DEC LSI-11, and other parallel interface computers equipped with NI DIO modules. Software support is provided for DOS (LabWindows) and Windows (LabVIEW), allowing for flexible programming and integration into existing systems.
Although it has been announced as obsolete by National Instruments, the AT-DIO-32F is still available from Apex Waves, offering a reliable solution for those in need of high-quality PC-based Digital I/O solutions.
