3.6.1 What is the preset function?
The BL-700 can store one bar code as preset data. It compares the preset data to
the bar code data actually read and outputs an OK/NG signal to whether there is a
match.
Using the BL-700 preset function, you can prevent the wrong products from enter-
ing the line without using a PC.
If no preset data is registered, the unit outputs OK when it successfully reads a bar
code and NG when it fails to read a bar code.
➮ See P.30 to 37 for output timing.
Use the setup software and serial command to register the preset data (
➮ See
P.68 and P.101).
Note: The bar code actually read can be compared to the preset data only in the
single label read mode.
