Diamond-MM-32X 32-Channel Analog I/O PC/104 Module February 1, 2015 Diamond Systems Corp. — No Comments DMM-32X-AT is an advanced embedded A/D board. It includes a comprehensive suite of analog and digital features to fit a wide variety of embedded application needs. The 32 A/D input channels feature high-accuracy 16-bit resolution, 250KHz maximum sampling rate, programmable input ranges, and user-selectable single-ended / differential configuration. The 4 D/A output channels feature user-selectable output ranges as well as a programmable waveform generator feature. The 24 digital I/O feature bit by bit direction programmability as well as buffers for enhanced output current of -15mA (logic 1) / 64mA (logic 0). The on-board programmable counter/timer circuitry includes a 32-bit counter/timer for A/D and D/A sample timing, as well as a 16-bit counter/timer for general counting, timing, and programmable interrupt functions. Extended temperature operation of -40oC to +85oC is tested and guaranteed. Using our patented auto-autocalibration technology, DMM-32X-AT will provide accurate analog measurements across its entire rated operating temperature range, ensuring reliable performance for critical applications. Our advanced Universal Driver software is included free with DMM-32X-AT and all our CPU and I/O boards. Universal Driver provides a programming library that simplifies control of all the board’s features and enables you to develop your application software quickly DMM-32X-AT includes Diamond Systems’ patented auto-autocalibration technology. This circuitry enables automatic calibration of the board in response to changes in temperature without requiring any involvement by the user or application program. An on-board microcontroller monitors the board’s temperature and uses on-board calibration circuitry to bring the board into calibration whenever needed, totally automatically. Typical accuracy post-calibration is +/-1LSB. The calibration threshold is set for 5 degrees C, which typically limits measurement errors to only +/-2 to +/-3LSB pre-calibration. 32 analog inputs, 16-bit A/D resolution250KHz A/D sampling rateProgrammable input ranges and input configurationSingle-channel, multi-channel round robin, and multi-channel scan samplingInterrupt-based A/D data transfer with FIFO support1024-sample A/D FIFO with programmable thresholdAutomatic autocalibration for carefree, high accuracy measurements4 analog outputs, 12-bit resolutionD/A waveform buffer of 1,024 samples with 100 KHz output rate24 high-current digital I/O with programmable directionCounter/timer for A/D pacer clock and D/A waveform generator-40ºC to +85ºC operation+5V only power supplyUniversal Driver software and technical manual included About Diamond Systems Corp.
