AO-1604CI2-PCI
Memory
Output data can be stored in driver's memory in advance so that DA conversion can be executed
repeatedly. You can select the memory type between FIFO and RING depending on the application of
analog output. The memory type is selected with software.
AO-1604CI2-PCI : Uses the memory for storing converted data on the driver.
- FIFO(First In First Out)format
Use FIFO format if you wish to output a continuous arbitrary analog output like that shown below.
When using FIFO format, writing of conversion data to memory is always performed from after the
most recent data and DA conversion is performed on the oldest data in memory.
You can write to memory during analog output operation.
An error occurs if the volume of data exceeds the memory size. However, this error does not stop
analog output if it is in progress.
- Ring format
Use ring format if you wish to output a repeated pattern like that shown below.
