Read MSR Data in Buffered Mode [51 01 xx]
commands for more details.
In buffered mode, the LED is set to slowly flash green until the reader is armed to read, at which point
it turns solid green. It remains green when the card track data is captured. When the host requests
the buffered data, the LED will briefly go dark during track decode then return to slow flashing green
if the read was successful; if the read was unsuccessful the LED turns red for .5 second and remain at
slow flashing green until it is rearmed. In normal operation the host will arm to read before the patron
tries to use the reader and will request the card track data immediately after the card is read so the
LED will be green for a successful read or red for an unsuccessful read. It will then revert to solid
green because the host immediately arms the reader to read the next card.
5.3.1.
Suggested steps for buffered mode application
1.
Run
53 1A 01 32
to set the reader to buffered mode (it only needs to be set one time; use
Configurator software, not in regular application; the result will be stored in EEPROM).
a.
The LED will slowly fash green.
2.
Run
50 01 30
to arm the reader to read.
a.
The LED turns solid green, indicating that it’s ready to read a card.
3.
Prompt the user to insert and remove a card.
a.
The LED stays a solid green and the card track data was captured.
b.
By default, the reader sends out the statuses for card inserted, card removed, and mag
data present.
c.
The host can discover the state of the reader by one of two methods:
i.
The host can wait for the reader to report that it has mag data buffered (from the
mag data present status) then request that data
ii.
The host can poll the reader for the track data.
4.
Poll for Read Buffered Data.
a.
Run
51 01 30
to read any track data (Or
51 01 3X
if for a specific track).
b.
The LED turns off while the card track data is processed.
c.
The LED turns RED for .5 seconds if any of the required tracks are bad or there is data on
an optional track that did not decode properly.
d.
The LED slowly flashes green otherwise and holds this setting until the reader is rearmed
or put into auto mode.
5.
Process the data.
6.
Display proper notification to user.
7.
Go back to step 2 for next the read.
