When the route has been sent to the Route Management software, The Portable
Interrogator 400 will ask you if the route was successfully transferred. The Portable
Interrogator 400 does this to insure that problems in other systems do not cause the
readings to be lost.
If the readings were successfully transferred and the Route Management software now
has them, press the Successful button. If a problem occurred, press the Not Successful
button. (Note that when the route is successfully transferred to the PC, The Portable
Interrogator 400 automatically clears the route and reading information. This allows you
to load the next route without manually clearing out the old readings.)
Canceling Communications
Sometimes communications between two computers has problems. One computer might
crash, stopping the communications process in its tracks, or the cable between the two
computers becomes dislodged from one of the two ports. When these types of conditions
occur, the communications process must be cancelled and both computers returned to
their original states.
The Portable Interrogator 400 has two important communications safeguards. First, if
The Portable Interrogator 400 sees no communications on the serial line for more than
three minutes, it will automatically stop the communications process and return to the
Transfer Routes menu as if nothing happened. Second, a button will appear on the screen
showing that the communications are in progress that allows you to cancel the
communications process. If you push the button, the communications process will be
halted and The Portable Interrogator 400 will return to the Transfer Routes menu.
These safeguards insure that, whether you are monitoring the communications or you
have just stepped out, if a problem occurs in the communications with the Route
Management software, The Portable Interrogator 400 will detect the problem and take the
appropriate action.
