COMMAND LIST
The following commands are available for use with the readers.
Reset Device Command
Command number: 0x02
Description: This command is used to reset the reader. This command can be used to
make previously changed properties take affect without having to unplug
and then plug in the reader. When the reader resets, it automatically does
a USB detach followed by an attach. After the host sends this command
to the reader it should close the USB port, wait a few seconds for the
operating system to handle the reader detach followed by the attach and
then re-open the USB port before trying to communicate further with the
reader.
When an Authentication sequence has failed, only a correctly MACed
(See Section 1, Security) Reset command can be used to Reset the reader.
This prevents a dictionary attack on the on the keys and minimizes a
denial of service attack.
Note
When the reader begins an Authentication Sequence, the Reset command will not
be honored until after the Authentication Sequence has successfully completed,
the user swipes a card, or the unit is power cycled.
