Data recording considerations 

The  VibraCorder  is designed to be powered with a rechargeable Li-Po battery. The minimum 
continuous recording time is defined as 15 hours. The recording will be automatically broken down to 
multiple files of the user selected size. No data shall be lost between files (internal buffer shall store 
information during new file creation process).  That means if the recorder is left in free run or time 
triggered mode, it will record the data TEST#001.txt (in this example, the first four characters of the 
file name are generic – if user selects nothing in the file name field during the config.txt creation), then 
it will close TEST#001.txt, open new file TEST#002.txt and continue the recording. It will execute that 
operation every time the specified file size is reached until it reaches TEST#999.txt or the battery runs 
out. In case the battery runs out earlier than TEST#999.txt file name is reached, the VibraCorder will 
close the current acquisition file and shut itself down.  

The tables below show LED troubleshooting codes for any possible issues during the start-up:

Serial Interface 

The device has a built-in serial interface for calibration and settings. Any terminal application can be 
used to access the communication protocol. In order to access the settings mode, the following steps 
must be taken: 

1.

 

Connect the device to a PC with terminal application installed. The device must be powered off 

2.

 

After the USB interface enumerates the device, check the device manager to identify the virtual 
COM port number assigned to the device by the PC

Setup serial communication parameters as shown below
