The IMU-P-S is configured at the factory according to the part number ordered. However, the need does arise for custom user-defined configurations depending on the application at hand. This User Manual will go through how to manually configure configuration parameters despite the inability to access Service Mode in SENSONAR STIM300 EVK PC Software.

Currently, the IMU-P-S has the ability to manually configure the following parameters: Sample Rate, Filter Cut-Off Frequency, Gyroscope Output, Accelerometer Output, Inclinometer Output, Termination, Baud Rate, and Datagram Structure.
Step 1. Begin by building a Parameter String in the following format using Table 1:
Where the highlighted values corresponding to the following:
S: Sample Rate
F: Filter Cut-off Frequency
G: Gyroscope Output
A: Accelerometer Output
I: Inclinometer Output
D: Datagram Structure
B: RS-422 Baud Rate
Table 1. Parameters and corresponding character for configuration string.
*When choosing the filter settings, it is recommended that the Filter Cut-off Frequency (F) is less than 1/4 of the desired Sample Rate (S).
**These options are configurable but the corresponding fields of the datagram will be popuated with zeros.
Loading Configuration onto Device
Step 2. Begin by connecting your device to the included data cable.

Step 4. Modify the following line indicated above like so:
Step 5. Save the file IMU_P_FLASHER.bat. After saving the file , double click on it to run. The following screen will be displayed prompting the user to enter in the serial port (COM port) and the device's Serial Number (as displayed on the unit, following the "I").
