Symbologies
MicroPDF417

A variant of PDF417, a very efficient and compact stacked symbology that can encode up
to 250 alphanumeric characters or 366 numeric characters per symbol.
Fixed Symbol Length Status
When Enabled, the imager will reject any MicroPDF417 symbol that does not match the
Fixed Symbol Length.
Fixed Symbol Length
Used to increase data integrity by ensuring that only one symbol length will be accepted.
When enabled, the MicroPDF417 symbol must contain the same number of characters as
the symbol length setting before it can be considered a good read. The imager will ignore
any symbol not having the specified length.
Note: Fixed Symbol Length Status must be enabled for Fixed Symbol Length to take effect.
