Black Box A/C-7P RO manual 7P RO, A/C-7S RO

A/C-7P RO, A/C-7S RO

Width parameters are ignored when printing POSTNET bar codes, since POSTNET uses one standard width. However, a valid value (1-9) must be entered for the width parameter to ensure the bar code command string is complete.

<hr>: Identifies whether human- readables are printed or not. Human-readables are printed underneath the bar code. Valid values are:

0 = Do not print human readables.

1 = Print human readables.

<chkd>: Indicates whether the A/C- 7 RO automatically calculates and causes a check digit to be printed. The following bar codes require a check digit, so, the A/C-7 RO automatically generates and adds a check digit to the bar-code data: Code 128, POSTNET, UPC A, EAN 8, EAN 13

If any of the bar codes listed above has been selected, the <chkd> selection is ignored by the A/C-7 RO. However, one of the following values must be entered to ensure the bar code command string is complete and valid. The options for the <chkd> parameter are:

0 = Do not calculate and add a check digit.

1 = Calculate and add a check digit to the bar code data.

<ast>: Specifies whether start/stop characters are automatically generated or manually added. This parameter only applies to bar code type Code 3 of 9. For all other bar code types, the start/stop characters are automatically generated by the A/C-7 RO and input for the <ast> parameter is ignored. However, one of the following values must be entered to ensure the bar code command string is complete and valid. The options for the <ast> parameter are:

0 = Do not automatically add start/stop characters.

1 = Automatically add start/stop characters.

NOTE

If value 0 is selected, you must manually enter

start/stop characters (asterisks) together with the data. Failure to add the asterisks will cause an invalid bar code to be printed (i.e. a bar code without start/stop char- acters). If human readables are being printed, the asterisks will also print as human readables.

If value 1 is selected, you must not add asterisks as start/stop characters to the data. Failure to omit asterisks will cause an invalid bar code to be printed (i.e. a bar code with a start/stop character pair in the beginning and a start/stop character pair in the end.)
