When a bar code is scanned, additional information is sent to
the host computer along with the bar code data. This group of
bar code data and additional, user-defined data is called a
“message string.” The selections in this chapter are used to
build the user-defined data into the message string.
This chapter is broken down into 3 sections. On pages 5 - 2
through 5 - 9 , you’ll find the message string selections for a
keyboard wedge interface. On pages 5 - 10 through 5 - 13,
you’ll find the selections for an RS-232 interface. On pages
5 - 14 through 5 - 16 , are the Prefix Code I.D. and Suffix Code
I.D. selections, which are used with both the keyboard wedge
and RS-232 interfaces.
It is not necessary to build a message string. When you
programmed your Terminal Selection, a set of defaults for the
message string was also programmed. The selections in this
chapter are only used if you wish to alter the default settings.
These defaults are noted at the beginning of each Interface
section, as well as on the Programming pages by an asterisk
(✱) beside each default value.
