All Symbologies
If you want to decode all the symbologies allowable for your scanner, scan the
All Symbologies On code. If on the other hand, you want to decode only a
particular symbology, scan All Symbologies Off followed by the On symbol for
that particular symbology.
All Symbologies On
All Symbologies Off
Note: When All Symbologies On is scanned, 2D Postal Codes are not enabled.
2D Postal Codes must be enabled separately.
Message Length Description
You are able to set the valid reading length of some of the bar code symbolo-
gies. If the data length of the scanned bar code
doesn’t match the valid read-
ing length, the scanner will issue an error tone. You may wish to set the same
value for minimum and maximum length to force the scanner to read fixed
length bar code data. This helps reduce the chances of a misread.
EXAMPLE: Decode only those bar codes with a count of 9-20 characters.
Min. length = 09Max. length = 20
EXAMPLE: Decode only those bar codes with a count of 15 characters.
Min. length = 15Max. length = 15
For a value other than the minimum and maximum message length defaults,
scan the bar codes included in the explanation of the symbology, then scan the
digit value of the message length and Save bar codes on the Programming
Chart inside the back cover of this manual. The minimum and maximum
lengths and the defaults are included with the respective symbologies.
