PROGRAMMING
SCROLL MATCHING EXCEPTION STRINGS ON/OFF
Scroll Matching is a feature to better remove those advertising scrolling messages on the customer display of cash
registers so they do not clutter up the video recording. To better understand how to use this, first we must discuss how
the Exception String is processed.
Exception Strings (with Scroll Matching OFF) are compared to any text in a line or any text after a CR LF up to 20
characters. If the line is longer than 20 characters we insert a virtual LF CR. Therefore exception string can not be longer
than 20 characters. If you use a wild card in front of or behind of a normal exception string then no matter what letter is
recieved in that position of the wild card it will be accepted as part of exception string.
Typically to erase these scrolling messages we would use the Negative Exception feature and turn “Off” the display after
we entered in the words with or without wildcards. However this left many unwanted bits and pieces of the scrolling
message visible because the transactions interrupt the scrolling message and then when the transaction is completed
the scrolling message goes back to the exact place in the message where it was interrupted. This is different than normal
transactions for they always start with a the description, quantity and price usually in one line.
In scrolling messages we may not have LF and sometimes no CR. This has the first character of every line different of the
scrolling message possibly different and even partial words starting at any place within any one of the words of the
scrolling message. Therefore conventional Exceptions even with the wild card does not remove all.
Scroll Matching “On” allows you to enter an exception string with or without wildcards and no matter when this string is
detected the entire line is erased. This feature “On” does not process the exception string any differently than normal
exceptions with Display “Off” but gives a higher priority than any normal exception set with Scroll Matching “Off” and
Display “On”.
This means that if you set an Exception for “Shipping” with or without a dollar figure associated and a normal transaction
that you wanted to generate an exception and set Display “On”. Everytime you hit the “Shipping” key your would get an
exception. However if you had a scrolling message “You can rely on us for all your Shipping needs” Then you might want
to erase this entire line and by doing so the word shipping would be included in the exception with scroll matching “On”.
In this case you would never see the normal transactions with Shipping $4.50 either as an exception or displayed for the
Scroll Matching would override.
A rule of thumb is to never use a scroll matching word the same word as any word in an item description or any partial
word that is a partial of any item description.
VSI-Pro VIDEO SERIAL INTERFACE
HISTORY BUFFER
Choices : ON ,OFF
The history buffer stores all the exceptions that are occur in VSI-Pro. Sometimes this can be very large and consume a
large portion of the memory of the VSI-Pro. This can be used to automatically search a compatible DVR, upload to a PC
to save or print out and view on screen on the VSI-Pro. This setting allows the user to enable or disable this feature as to
conserve memory allocation for other features.
To make your selection, press the “Up” or “Down” button to move the cursor to “HISTORY BUFFER” and press “Set”.
Press the “Up” or “Down” button to toggle between “ON” or “OFF”. Make your selection and press “Set”. The cursor will
stop flashing and you may continue to the next menu item.
Remember, you must turn the HISTORY BUFFER “ON” for exceptions to be saved in history.
