Bar Code Length
The Bar Code Length parameter selects the method for determining if an Interleaved 2 of 5 bar code is a valid length. The Range Check method identifies a length range by specifying the minimum and maximum number of characters. The Specific Check method identifies two specific bar code lengths by specifying the number of characters in each. With this option, the number of characters in all
Interleaved 2 of 5 bar codes must be one of the two numbers. Scan the Hex 0 tag to use the Range Check method, scan the Hex 1 tag to use the Specific Check method. The default is the Range Check method.
Value 1 and 2
The Value 1 and Value 2 parameter specifies the valid
Interleaved 2 of 5 bar code lengths. Use this option with the Bar Code Length parameter option described in Bar Code Length. If you select the Range Check method, Value 1 specifies the minimum number of characters in a valid Interleaved 2 of 5 bar code and Value 2 specifies the maximum number of characters. If you select the Specific Check method, Value 1 contains one specific number of characters and Value 2 contains another.
Accepted values for Value 1 and Value 2 are 4 to 38 readable characters. The number of readable characters must be an even number; if you specify an odd number, it is rounded down one. Each value is input using two Hex tags. The first can be Hex 0 through Hex 3 and the second can be Hex 0 through Hex 9. The default for Value 1 is 08 and for Value 2 is 16
Check Digit Present
The Check Digit Present parameter permits you to determine if the bar code must contain a correct check digit to be identified as valid. If this function is enabled, the bar code is ignored if a check digit is not present. Scan the Hex 0 tag to disable this option, or the Hex 1 tag to enable it. Disable is the default.
