DMM-32X-AT is Diamond Systems' most 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 -40 to +85°C is tested and guaranteed. Using our patented autoautocalibration 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.
Digital and Counter/Timer I/O Features
DMM-32X-AT features 24 digital I/O lines and 2 82C54-type counter/timers just like its predecessor DMM-32X-AT. The I/O lines can be programmed for input or output in groups of 8 bits. In output mode the lines are buffered for enhanced output current capability. All DIO lines feature jumper-selectable pull-up / pull-down resistors as well as ESD protection devices to help prevent field failures.
The counter/timers emulate an 8254. Counter 0 is standalone and can be used for general purpose counting, timing, or timer-based interrupts. Counters 1 and 2 are joined together to provide a 32-bit timer for A/D sample rate control or D/A waveform output control.
