Mifare; Mifare Commands; Authentication - B&R Automation Panel 9 D Series User Manual

Procedure in Windows:
1) Enter command "Firmware_Upgrade" to put the transponder reader in upgrade mode.
2) Depending on the Windows system settings, the transponder reader will automatically be registered as a
USB mass storage device.
3) A new drive will appear in Windows Explorer (e.g. D:\).
4) Open the new drive in Windows Explorer.
5) Delete the firmware.bin file located there.
6) Copy the new firmware file (e.g. firmware_80.bin) to the drive.
7) The transponder reader should now be modified by the new firmware.
8) The transponder reader must be restarted to complete the upgrade procedure. This is done by disconnect-
ing and reconnecting the USB port or by switching the device off and back on again.
9) It is possible to check the firmware version with command "show_revision" or command "firmware_info"
after a restart.

7.4.3 MIFARE

7.4.3.1 MIFARE commands

Command Description
Read Reads a 16-byte block from PICC
Read_Blocks Reads the specified range of blocks from PICC
Write Writes a 16-byte block to PICC
Decr Takes the value of the source value block, subtracts the
specified value and writes the result to the destination
block
Incr Takes the value of the source value block, adds the
specified value and writes the result to the destination
block
Restore Copies a value block
InitZero Initializes a value block with the value 0
Store_Key_EEPROM Stores a 6-byte key in EEPROM
Store_Key_Temp Stores a 6-byte key in the transponder reader temporar-
ily until switched off
Connect Connects manually to a specific tag
Disconnect Automatically restores a connection to the best tag
Key_CMD Sends a key directly with each command (default)
Key_EEPROM Uses the key from EEPROM
Key_TEMP Uses the temporary key

7.4.3.2 Authentication

The keys needed for authentication can be stored either in EEPROM or temporarily in the transponder. Alterna-
tively, the authentication keys can be transferred with the command.
Commands Key_EEPROM, Key_TEMP and Key_CMD are used to set the storage location or to send the authen-
tication keys.
The following commands are used to store the authentication key in the transponder:
