Data Flow

The following explains the data flow in the reader for a better understanding of how
data is processed.
Barcode:
Read Barcode
If symbology (barcode type) not allowed - ignore
If pdf417, check for driver's license parsing and parse if required.
If masking is on, mask the barcode according to the mask specifications.
If rs232, tcp/ip, f2f, aba, or wand output - transmit data (finished)
If wiegand output - generate the wiegand output data (bits). If successful, transmit
the wiegand data (finished). If not sucessessful, ignore data.
Prox/iClass:
Read Card
If a wiegand output reader, and passthru is turned on - pass the prox/iClass data to
the wiegand output undisturbed.
If card bit length matches a defined format, extract the numbers for each defined
field. If it does not match a defined format - ignore. If any of the field descriptions
cause an overflow to occur - ignore.
If masking is on, mask the resulting data according to the format.
If rs232, tcp/ip, f2f, aba, or wand output - transmit data (finished)
If wiegand output - generate the wiegand output data (bits). If successful, transmit
the wiegand data (finished). If not sucessessful, ignore data.
