Manufacturer: Diamond Systems Corporation
The Ruby-MM series provides 4, 8 or 16 channels of 12-bit resolution analog voltage outputs plus 24 digital I/O lines on a single PC/104 module. An on-board precision voltage reference circuit offers analog output ranges of 0-2.5V, 0-5V, and 0-10V in unipolar mode or ±2.5V, ±5V, and ±10V in bipolar mode. All analog outputs can source or sink up to 5mA simultaneously.
The analog outputs are based on the DAC8412 quad 12-bit D/A converter chip. This chip resets all outputs to mid-scale on power-up, meaning 0V for bipolar ranges and 1/2 the full-scale voltage for unipolar ranges. To obtain power-on reset to 0V for unipolar ranges, a special-order version is available using the DAC8413 which powers up to zero scale instead.
On the 16-channel model, each group of 8 channels can be set for a different output range. On the 4- and 8-channel models, all outputs have the same output range. All outputs are updated simultaneously, either with a software command or in response to an external trigger.
The board includes 24 digital I/O lines using an 82C55 chip. All I/O lines have 10K Ohm pull-up resistors for guaranteed logic levels on power-up.
Ruby-MM-1612 is designed and tested for extended temperature operation (-40ºC to +85ºC). It requires only +5VDC from the system power supply via the PC/104 bus. Analog ±15V supplies are derived from miniature DC/DC converters on the board. All I/O is contained on a single 50-pin connector compatible with standard .1” connector ribbon cables, such as Diamond Systems’ C-50-18.
The analog output ranges are selected with a jumper block on the board.: 0-5V, 0-10V unipolar, ±5V, ±10V bipolar.
Universal Driver software provides a high-level programming library for all of Diamond Systems’ I/O boards, as well as the data acquisition circuitry on our SBC boards. All the features described above are supported with easy-to-use function calls, resulting in a reduced learning curve and shortened application development time. The Universal Driver works with Linux, Windows 2000/XP, Windows CE and DOS. Application examples and projects are included for each function, each board, and each operating system to provide a quick starting point for learning and development.
