Symbol Quality
Overview of Symbol Quality
Information about symbol quality and timing can be appended to symbol data output by
enabling specific parameters in ESP or by serial command. The order that these values
will be appended corresponds directly to the order in which they appear in this section and
in the ESP Symbol Quality menu.
Symbol Quality parameters are separated into ISO/IEC 15415, Grading, and Inkjet/Direct
parameters. In addition, there are two parameters, Total Read Time and Symbol Quality
Separator, that are common to all.
Reports
You can receive comprehensive reports by sending a <VAL> command to obtain an ISO/
IEC 15415/Grading Symbol Quality Report or a <VAL2> for Inkjet/Direct Marking report.
Discrete Outputs
Symbol Quality parameters can also be programmed to toggle discrete outputs in
response to symbol quality changes (see "Symbol Quality to Output 1 (ISO/IEC
15415)" on page 5-46).
