STX104 Reference Manual 16-bit Analog I/O Module with 1M sample FIFO and dual 16-bit DACs
●What is the STX104? The STX104 is a 16-channel 16-bit analog input and 2-channel 16-bit analog output card. The STX104 incorporates a large one mega-sample FIFO.
●Description
■What are the Benefits of using the STX104? The STX104 has the following benefits:
▲One mega-sample FIFO data storage provides continuous data streaming from ADC to CPU with reduction in interrupt overhead and relaxation of interrupt latencies.
▲200,000 Samples per second aggregate for analog inputs
▲Analog input 16-Sample moving average filters for data noise reduction
▲Compatible with DAS16jr/16 and DAS1602 for using existing 3rd party drivers
▲16-bit data read (ADC data) operations double effective PC/104 bus bandwidth
▲16-bit data write (DAC data) operations reduce software overhead
▲Use REP INSW (286 or higher CPU) to read-in blocks of ADC data from FIFO further increasing bandwidth and reducing complexity.
▲Burst mode with only one interrupt generated per complete scan, thus reducing interrupt overhead and increasing effective throughput.
▲One interrupt per 512-samples is possible in FIFO mode
▲On-board LED to indicate that the STX104 is being addressed. By observing the LED you can quickly determine system activity.
▲Polarized locking I/O connector. This eliminates board failures due to incorrect connector orientation.
▲Extremely low DC drift
▲External trigger input (DIN0) is deglitched preventing unwanted ADC triggers. Minimum valid pulse width required is 200nS.
▲Industrial temperature range from -40℃ to +85℃
▲No tantalum capacitors or electrolytic capacitors used in the design
▲Single +5V supply operation
