How to disable ThreadMode for devices 7024M-5A, 7203, 7017, 7027, 7037, 7017d, 7028M

ThreadMode is used in document readers that operate with the OV5640 image sensor from OmniVision. This mode allows all frames received from the image sensor to be sent to the upper level for analysis. While frames are being received and synchronized, the USB bus is loaded, and this load may cause the software and/or the device to freeze on computers with low technical specifications.

Sometimes the following situations may occur:

• after a certain period of inactivity, the reader stops responding to a document placed in it;
• when the scanning process is forcibly started in the Document Reader application, nothing happens, or the application may freeze;
• In the DebugView application, the log shows multiple messages about corrupted frames, or bad frames.

In these cases, one possible solution is to disable ThreadMode.

• ThreadMode - 0 means the mode is disabled. All frames are sent to the upper level, but only at the moment of capture.

To disable ThreadMode:

1. Place RegulaReader.json file from the archive into the following folder:
   C:\ProgramData\Regula\Document Reader SDK
   or
   C:\ProgramData\Regula\Document Reader SDK (x64) –  depending on the version used.
2. Reconnect the device.
