products that carry UPC bar codes, placed there by the manufacturer. The Code 128 bar 
codes have the following format:

MMMMMPPPPPDD

Where:

M = Manufacturer ID

P = Part Number

D = Destination Code

The distribution center uses a PC with dedicated control characters for manufacturer ID 
<CTRL M>, part number <CTRL P>, and destination code <CTRL D>. At this center the 
UPC data is treated as manufacturer ID code.

The following rules need to be entered:

When scanning data of code type Code 128, send the next 5 characters, send the 
manufacturer ID key <CTRL M>, send the next 5 characters, send the part number key 
<CTRL P>, send the next 2 characters, send the destination code key <CTRL D>.

When scanning data of code type UPC/EAN, send all data, send the manufacturer ID 
key <CTRL M>.

To enter these rules, follow the steps below:
