The ASD2811-R is an expansion board, or daughter card, that serves as a remote analog input device. The board has eight 12-bit analog inputs through a 100-pin expansion connector and offers two unipolar and six bipolar input range settings, handled via onboard 16-band DIP switch. Each input can be configured as either 10V, 5V, 10mV, or 5mV ranges. This makes it ideal for applications such as temperature measurement, in which it can measure a wide range of values.The CARD-2811-R also includes several internal signal conditioning features, such as switchable input protection, selectable source terminations, and selectable low-pass filters. Each channel can be individually programmed to support one of the four input ranges and the adjustable filter parameters. Additionally, offset and gain values can be stored for each input channel to automatically calibrate the system. The board also offers the option of using the on-board converters and analog outputs, or connecting external analog outputs or multiplexers.To make use of the ASD2811-R in an application, it must be connected to a controller or host computer using ISA, PCMCIA, or other either serial or parallel data communication protocols. The controller then performs analog-to-digital conversion on the incoming data and is responsible for providing the necessary signal conditioning for the on-board analog inputs. In addition, the controller is responsible for programming the on-board DIP switches to select the desired input ranges and signal filtering parameters. This process typically is done with an application-specific software package that is provided with the board.Once connected to a host system, the ASD2811-R works by converting an analog input signal into a digital signal that can be read and processed by the host system. The onboard converters are responsible for performing the initial conversion, and the on-board 16-band DIP switch is used to select the desired input range. The signal is then filtered in order to reduce noise and other unwanted signals, and is then output as a 12-bit digital word. The board also has an on-board clock that is used to time the conversion process.The board has been designed for rugged, industrial use, and is capable of withstanding extreme temperatures and other hostile environments. It is also configured to work with both Windows and Linux operating systems, allowing a wide range of applications. All connections use either a PCMCIA interface or ISA bus protocols, and the board is compatible with popular commercial development tools such as Visual Studio and Borland C++.Overall, the ASD2811-R is an ideal solution for many remote analog input applications. It offers a wide range of analog input range settings, and is designed to work with a variety of operating systems. The board also includes onboard signal conditioning features and on-board clock to ensure accurate and reliable performance. With its rugged design and compatibility with popular development tools, the ASD2811-R is capable of meeting the needs of a variety of industrial and commercial applications.
