Aitech’s S930 Analog IO card design is based on a 12-bit resolution analogue to digital converter and a 12-bit resolution digital to analogue converter. The S930 is designed with a PCI bridge implemented by an anti-fuse FPGA allowing a processor module like S950 to access the analogue I/Os from the cPCI bus.
The S930 provides 64 analogue inputs and 2 analogue outputs. Of the 64 inputs, 51 inputs are assigned to external inputs, 2 inputs are used to monitor the output channels, 6 inputs are used to monitor the power sources, 4 inputs are used to monitor the references and BIT signals, and 1 channel is not used (grounded). The S930 operates in a single conversion mode, i.e., all analogue inputs and outputs perform their conversions once upon receiving a start command. The conversion data is stored in the buffer memory. Once the conversions are completed, an SDONE bit is set. The SDONE bit may be polled by the host processor or can be set by software to generate a software-configurable cPCI bus interrupt.
