Embedded CPU takes analogue I/O and PSU onboard
The Hercules-EBX is the first embedded CPU to integrate a Pentium-III class processor, professional-quality analogue I/O with autocalibration, and a wide-input DC/DC PSU on a single EBX-format board.
PC/104 CPU takes data acquisition onboard
A new PC/104 board integrates a Pentium-II class CPU running at 200MHz, 128Mbyte memory, Ethernet and a professional-quality analogue and digital I/O circuit with autocalibration.
The auto-autocal feature of DMM-32X-AT represents a major step forward in embedded analogue I/O technology.
Although other analogue I/O boards contain autocalibration circuitry onboard, they require application software to manage the calibration process.
This creates support problems for customers using operating systems or programming languages not directly supported by the board manufacturer.
The DMM-32X-AT, however, contains all the intelligence and control needed for the calibration process directly onboard.
This means it can calibrate itself whenever needed, in response to a user-programmable delta in ambient temperature.
No software or user intervention is required.
The board is completely self-sustaining, resulting in carefree accurate analogue measurements over the lifetime of the product.
Another unique feature of DMM-32X-AT is its built-in RS232/485 serial port and onboard microcontroller for remote communications.
This enables the DMM-32X-AT to be used stand-alone as a remote measuring device with no CPU required.
All board features can be accessed over the serial port just as they would via I/O commands in a standard CPU plus I/O configuration.
The board has 32 analogue inputs with 16bit A/D and 250kHz sample rate, four analogue outputs with 12bit D/A and 100kHz waveform output capability, 24 digital I/O lines, two counter/timers, and an operating temperature range from -40 to +85C.
Diamond Systems' free Universal Driver programming software is included, which supports Linux, Windows 98/2000/XP/Xpe/CE.NET, DOS, QNX and VxWorks.
The DMM-32X-AT is 100% backward compatible with Diamond Systems' industry-leading DMM-32-AT board, which is already used around the world in industrial, military, aerospace, medical and scientific applications.
The DMM-32X-AT module can act as a drop-in replacement, providing an instant upgrade for improved performance due to its faster sample rate, lower noise, larger A/D sample FIFO, D/A waveform capability and auto-autocal feature.
