Message Intersect & Pack
Introducation
This chapter introduces Message Intersect & Pack.
Message intersection only affects plain barcode message.
Plain barcode message usually consists of several information sections. Sections may
consist of several bytes and have specific indications such as merchandise ID, manufacturer
and so on.
Intersection can select section(s) required to transmit, and thus to skip other unnecessary
sections in the result shown.
Normally the processing sequence is:
“
read to obtain plain barcode message
”—
>
“
intersect
”—
>
“
append prefix/suffix
”—
>
“
append stop suffix
”—
>
“
transmit
”
A special programming, pack, can insert barcode messages into a certain message format.
Then the processing sequence is:
“
read to obtain barcode message
”—
>
“
intersect
”—
>
“
append prefix/suffix
”—
>
“
pack
”—
>
“
append stop
suffix
”
-
“
transmit
”
