6.1.7 Error Handling
When a situation results in an error and does not permit proper communication with the
CAM Module, an error message will be displayed. There are different conditions that can
lead to errors. Table 1 lists the possible error messages and their descriptions.
Error Message Description
Error: No session.

communication
The user is trying to answer a menu or enquiry and the session has
been closed.
Error: Session ID.
Refresh to recover
communication.
The user is trying to access a session that is no longer available.
Error: Status. Refresh
to recover
communication.
The status count value received from GUI is not the same as the one
in the CAM Interface. This means that the GUI could be in another
level of the menu which can lead to a non desired operation.

The message parsing process is not successful.
Error: CAM No
response. Refresh to
recover
communication.
Within a specified timeout, the CAM Interface failed to respond.

Table 2 - Error Messages and their Descriptions
When an error message is displayed, the Back/Exit button is replaced by Refresh. The
operator can either close the CAM Interface, or try to Refresh the session. If a
synchronization error occurs, Refresh is the ideal solution. Otherwise, the operator can
wait for the CAM Interface to request a Refresh automatically.
