Message Interception & Pack

Introduction

Barcode message could divide information into different sections, such as product ID, manufacture
ID, and so on. They are important overall. However, at certain situations, some of them are not
of interest. This is where message interception comes in. Message interception feature allows
transmission of selected section(s). Message intercept only applies to "raw" barcode messages.
The sequence of a read to transmit without message intercept is: Read a "raw" barcode —> Add
prefix —> Append suffix —> Append terminal —> Transmit to Host.
The sequence of a read to transmit with message intercept is: Read a "raw" barcode —>
Intercept Message —> Add prefix—> Append suffix —> Append terminal —> transmit to Host.
A special programming, pack, can insert barcode messages into a certain message format.
Then the processing sequence is: Read to obtain barcode message—> Intercept—> Add prefix—>
Append suffix—> Pack—> Append terminal—>Transmit.
