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.
To properly use the values returned from the SeaI/O-470 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
For ease of use, SeaMAX
functions to convert A/D and D/A values have been provided. Use of these functions is also
detailed in the SeaMAX Software Manual.
