Why
mus
t
I poll the
USB card
reader?
The nature
of
USB
is not
event driven per se,
it
operates on a
host
/
client
protocol
that during
enumeration asks
the
host
to poll at
a specific rate.
As
a keyboard
we
are polled
by the
OS
every
10msec,
the
same speed your keyboard and mouse is.
We
use feature
report
packets
to configure
the
readers.
We
also communicate
to the
DLL API through Feature Reports
for HID
devices. The
AK0
units
that
are RS-232
or
CDC can speak English
with
using
the
ASCII
COMMAND
PROTOCOL
such
as
“rfid:help”
in
Hyper Terminal
or putt
y
.
We
recommend you
poll the
units every 250msec
for the
card id, except
for AK0 unit
and
this with
a QueuedID, as
the
reader
will report the
age
of the
card
id
up
to 52
minutes.
Without the
SDK
the
units can send unsolicited card
id
when
the
card
is in the
rf
field. These appear as USB keystrokes
or
Serial data
for
RS-232 and CDC models. Take a look
at the
pcProx manuals
it
may help you get a better idea
of the AK0
protocol. The
HID is
a proprietary
binary
protocol, where as
the AK0
units are open
protocol.
