Description
The DAQCard-DIO-24 is a legacy data acquisition (DAQ) device with the part number 776912-01. This device falls under the category of Legacy DAQ Devices and is designed to be compatible with both Macintosh and PCs that come with a Type II PCMCIA slot. The core of this device is based on the 82C55A PPI (Programmable Peripheral Interface) chip, which facilitates digital I/O (Input/Output) operations on a PC Card.
The DAQCard-DIO-24 boasts 24 programmable I/O pins, which are distributed across three 8-bit ports, allowing for versatile configurations according to the needs of various applications. It supports multiple operation modes including Strobed I/O, Bidirectional Bus I/O, and Simple I/O, providing flexibility in data transfer and manipulation tasks.
For interface circuitry, the device is equipped with a card information structure, timing interface, data buffers, PC Card control registers, and an address decoder, ensuring efficient communication and data handling capabilities. The I/O channel features include a data bus, an address bus, support and control signals, and interrupt lines, all contributing to robust and reliable performance.
The DAQCard-DIO-24 utilizes a 25-pin I/O connector, and there is an optional cable, PSH27-50F-D1, available for connection to a 50-pin standard male connector. This expands the device’s compatibility and ease of integration with external digital circuitry. Speaking of which, it can supply +5 V through Pin 25 to external digital circuitry, drawing approximately 60 mA from the host PC.
Regarding accessories, the DAQCard-DIO-24 is compatible with the SC-2051 and CB-50, further enhancing its utility in a wide range of applications. Despite its Obsolete Status announced by National Instruments, it remains available for purchase and repairs through Apex Waves, ensuring continued support for users of this versatile legacy DAQ device.
