Description

After reading about our new Diamond-MM-32 board, we think you'll be convinced: There's simply no other board in the world that can compare with these features at any price. And that doesn't mean that this board is expensive. On the contrary, we've priced Diamond-MM-32 to compete with the standard 16-bit A/D boards that you'll find from our competitors around the world. Take a look at the performance and features described below and see for yourself.

	Automatic Calibration

Diamond-MM-32 is the first PC/104 analog I/O board to feature automatic calibration of both analog inputs and outputs for enhanced accuracy and reliability. The potentiometers, which are subject to tampering and vibration, have been eliminated. Instead, all A/D calibration adjustments are performed using an octal 8-bit DAC. The DAC values are stored in an EEPROM and are recalled automatically on power up. The board includes three precision voltage references for negative full scale, zero, and positive full-scale. A calibration utility program provided with the board allows you to recalibrate the board anytime, in both unipolar and bipolar modes, and store the new settings in EEPROM.

Autocalibration applies to the 4 D/A channels as well. The full-scale D/A range is selected with a jumper block. The analog outputs are fed back to the A/D converter so they can be calibrated without user intervention. Again, calibration settings are stored in EEPROM and automatically recalled on power-up

	Analog Inputs

Enhanced Analog Input Configuration

Virtually all other A/D boards require you to set all input channels in one mode, either single-ended or differential. Diamond-MM-32 provides split configuration capability, with more total input channels than any other PC/104 analog I/O board. The board can be user-configured in any of three ways:

	Programmable Input Ranges

A programmable gain amplifier, programmable unipolar/bipolar range, and programmable 5V/10V full-scale range combine to give Diamond-MM-32 a total of 10 different possible analog input ranges. All range settings are controlled in software for maximum flexibility.

Mode	Full-Scale	Gain	Input Range	Resolution
Unipolar	10V	1	0-10V	0.153mV
Unipolar	5V	1	0-5V	0.076mV
Unipolar	5V	2	0-2.5V	0.038mV
Unipolar	5V	4	0-1.25V	0.019mV
Unipolar	5V	8	0-0.625V	0.0096mV
Bipolar	10V	1	±10V	0.305mV
Bipolar	5V	1	±5V	0.153mV
Bipolar	5V	2	±2.5V	0.076mV
Bipolar	5V	4	±1.25V	0.038mV
Bipolar	5V	8	±0.625V	0.019mV

	Enhanced Trigger and Sampling Control Signals

We've added extra A/D trigger and sample control signals to the design. Seven auxiliary digital I/O lines on the analog I/O connector provide a sample/hold output signal, A/D trigger in and out lines (to enable synchronization of multiple boards), external A/D clocking,

	Analog Outputs

Diamond-MM-32 contains 4 12-bit analog outputs with autocalibration capability. Up to 5mA of output current per channel can be drawn from all channels simultaneously. Both unipolar and bipolar output ranges are supported with jumper configuration. And on power up, all outputs are reset to 0V automatically.

	FIFO and 16-Bit Bus Interface

An on-board 1024-byte FIFO enables Diamond-MM-32 to work with Windows 95 and NT by dramatically reducing the interrupt overhead. Each interrupt transfers 256 2-byte samples, or half the buffer, so the interrupt rate is 1/256 the sample rate. FIFO operation can be disabled at slow sample rates, so there is no lag time between sampling and data availability. The 16-bit interface further reduces software overhead by enabling all 16 A/D bits to be read in a single instruction, instead of requiring 2 8-bit read operations. The net result of this streamlined design is that Diamond-MM-32 supports gap-free A/D sampling at rates up to 200,000 samples per second, twice as fast as our previous boards.

	Designed for the Real World

Diamond-MM-32 continues the Diamond Systems tradition of design for real-life applications. The board requires only +5V from the system power supply and generates its own +/-15V analog supplies on board. The board operates over the Extended Temperatures range of -40 to +85º. As with all our I/O boards, Diamond-MM ships with free driver software for DOS, Windows 95, and Windows NT. And if one board isn't enough, you can stack two or more in the same system, and our Universal Driver software will support it.
