4. PROGRAMMING THE MICRODAC IV
4.1 Selecting the correct COM Port
The COM Port menu option within the File menu allows you to select the COM Port on which the
software will first attempt to communicate with MicroDAC IV when programming it. If you are unsure
which COM Port your MicroDAC IV is connected to, then leave it set at the default option of COM 1, and
the software will automatically search all COM Ports until the MicroDAC IV is found. An example of a
computer’s COM Port connections is shown in Figure 4-1.

4.2 Transferring the Filter Configurations
The Program MicroDAC IV button on the toolbar starts the process of searching for a MicroDAC IV and
transferring the filter settings to the MicroDAC IV via the serial port. This function can also be selected
through the File option in the Menu Bar. After the Program MicroDAC IV button is pressed, you will see
a window appear that asks you if you are prepared to program all seven filters. This is to remind you that
you only need to program the MicroDAC IV one time once you have all the filters set up the way you want
them.
Figure 4-2: MicroDAC IV Transfer Window
Several messages will appear in the transfer window ito inform you when the software is using the Auto
COM Port detection feature to find the MicroDAC IV, calculating the coefficients, and finally programming
the MicroDAC IV. The COM port that is being used to transfer the settings will appear in the lower right
corner of the Transferring Filters window. As the filters are transferred, the progress bar will display how
much of the total transfer has been completed. Once the transfer is complete, the window will disappear
and the Main Control Window will become active again.
