If rs232, tcp/ip, f2f, aba, or wand output - transmit data (nished)
If wiegand output - generate the wiegand output data (bits). If successful, transmit
the wiegand data (nished). 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 dened format, extract the numbers for each dened
eld. If it does not match a dened format - ignore. If any of the eld descriptions
cause an overow to occur - ignore.
If masking is on, mask the resulting data according to the format.
