Hardware considerations

Interleaving analog and digital output data

The cSBX-DDA04 board allows interleaving of analog and digital output data. To support interleaving, a control bit indicates the data type. The control bit is the MSB of each 16-bit word of analog or digital data. The MSB = 0 for analog data and the MSB = 1 for digital data.

The data is passed to the board and then directed to the correct output type by hardware on the board which detects and acts on the MSB control bit.

• To use this interleaving capability with the Universal Library, set HighChan and LowChan to NOTUSED, and indicate the data type and channel in the most significant four bits of the data values in the buffer.
• To use this interleaving capability with the Universal Library for .NET, set HighChan and LowChan to NotUsed, and indicate the data type and channel in the most significant four bits of the data values in the buffer.
