Troubleshooting
The following is a list of error messages or unexpected functionality that may be
encountered, and how these issues can be addressed.
No response from reader.
Make sure the correct tag type is chosen in the main Demo screen (see step
2 under “Program Details” for more information).
Demonstration type grayed out.
The current tag type selected does not support the functionality that is
grayed out. For example, if the tag type doesn’t have decrement capability,
the ticketing mode will be grayed out for that tag.
Reader beeping.
One beep from the reader means an operation was completed successfully. If
there are two beeps then the operation was unsuccessful. An unsuccessful
reader operation may occur if:
 -The tag was presented in rapid succession
 -The incorrect tag is selected under “tag type”
Wrong demonstration type selected, need to return to main setup page.
In order to return to the main demo page, close the window that is currently
running. To do this, click on the upper right hand corner, or press the ESC
key.
Reader and/or program not responding.
Reset the reader by disconnecting from the computer and waiting a short
period before reconnecting. Close the program and restart by clicking on the
shortcut icon, or selecting it under the program menu.
Error message: There does not seem to be a USB Virtual Com Port Installed. You
will need to install the USB COM port driver to communicate with Kovera readers.
This message may also appear if the drivers are installed but no Kovera reader is
connected.
The program has detected that there is no reader connected to the
computer. A Kovera reader must be connected in order to run the Demo
program.
Error message: There does not seem to be a functioning reader on COM(X) at
address N.
The program has not detected a reader on the port(X) selected; make sure
the reader is connected to the selected port. Also make sure that the reader
address has been set correctly to 0, the correct port has been selected, and
the cable is properly functioning. The power on reset default address is 0.
