Overview / Features
This product is PCI-compliant interface boards that convert analog input signals to digital equivalents (performing analog- to-digital conversion). This product can perform A-D conversion at a conversion speed of 20µsec per channel and a resolution of 12bit. Windows/Linux device driver is supported with this product.
-
Bus-isolation by optocoupler and digital isolator
- PC and external I/O circuit is isolated from each other by optocoupler and digital isolator, offering good noise immunity.
-
Sixteen single-ended channels and eight differential channels
- Either board allows the single-ended or differential input mode to be selected with on-board jumpers. The order of channels subject to signal conversion can be
preset in the dedicated register.
-
On-board buffer memory
- The board has buffer memory available as a FIFO or ring buffer to hold 256 kilobytes of data. This enables sampling to be executed in the background independently of the processing power of the PC.
-
Assorted sampling control functions
- The board can control the starting and stopping of sampling not only with software commands but also by detecting analog signal strength or digital signals. The
board offers a choice of sampling clocks selectable to determine the sampling speed: the internal sampling clock using the on-board clock generator and the
external sampling clock using the digital signal input from an external device.
-
Digital input/output function
- The board has optocoupler isolation open-collector output (sink type) digital output 4 channels, optocoupler isolation input (corresponding to sink output) digital input 4 channels and can monitor, control the external device.
-
Windows/Linux support device driver
- Using the device driver API-TOOL makes it possible to create applications of Windows/Linux. In addition, a diagnostic program by which the operations of hardware can be checked is provided.
