The board is based upon Linear Technologies' precision converters and voltage references which require no external calibration. The digital I/O utilizes WinSystems' versatile WS16C48 implementation, also available on many of our SBCs and other I/O products. Analog Input Section - Two analog-to-digital converters (ADCs) are used on the board. Each contains an 8-channel multiplexer with ±25V protection. The multiplexer on each ADC can be programmed for single-ended inputs or pairs of differential inputs or combinations of both. The precision trimmed attenuators ensure accurate input ranges. All channels are fault protected so that a problem on one channel will not affect the conversion result of another channel. The PCM-MIO-G supports four input voltage ranges. Any input range is independently software selectable for each channel. No jumpers are required. The board will support up to 16 single-ended input channels, eight differential input channels or various combinations of both. This means that under software control, any channel can be set for either single-ended or differential along with its voltage range.

PCM-MIO-G: ADC, DAC, and DIO PC/104 Module Analog Output Section - The PCM-MIO uses two Linear Technologies SoftSpanTM quad Digital-to-Analog converters (DACs). They are software programmable for either unipolar or bipolar mode plus specific voltage range on a per channel basis. There are eight independent, 12-bit, D/A channels, each with six programmable output voltage ranges. They are asynchronously cleared to 0V for all ranges when reset. Digital Input/Output Section - The PCM-MIO-G contains WinSystems’ highly-versatile WS16C48, 48-line digital I/O controller. There are 48 bits of bidirectional...
