A/D & D/A Diagnostics
To check basic functionality of both the A/D and D/A converters, press the
“Diagnostics Utility” button on the “D/A Outputs” tab (shown on the previous page)
and then press the “Start” button, as shown below. Any errors will be shown in the
“Results” pane. If any errors occur, please contact technical support for further help.
Converting A/D & D/A Values
To properly use the values returned from the SeaI/O-470 and SeaDAC 8227
module’s A/D channels, the application program must convert the returned values to
engineering units (voltage). Likewise, the application program must output the
correct value to the I/O module’s D/A outputs to generate the desired voltage.
The conversion formulas will vary depending on how the I/O module is configured.
The formulas and their uses are covered in detail in the interactive documentation
located on the Sealevel website at:
