String
(32 chars max)

message sent to the host. The default is Blank, which means a header
message is not defined. An example header message is BAR CODE
DATA.

Field Type Options
Edit Numeric
ASCII Numeric
(1 – 255)
255 = None
Defines the three digit decimal ASCII character that will indicate the
beginning and end of bar code label data. If multiple symbols are
being read, the delimiter also separates each field in the message. A
double delimiter (two consecutive occurrences of a delimiter
character) indicates the end of a package.
The default is None or 255, which means no delimiter is defined.
When choosing a delimiter, be careful to select a character that will
not appear in the bar code data.

Edit Numeric
1 through 16
0 = All
Determines the number of bar code symbols to include in each
message. The default All sets the value to equal the number of
symbols per package. The values 1 through 16 will set this value to a
specific number of fields. (See Symbols Per Package, Chapter 7, and
Host Replacement Rules: Host Message Field Number, Chapter 10,
for more information.)
