The
Reader USB CRX14 Demokit V4.0
tools are designed to demonstrate the STMicroelectronics short range product portfolio that includes the SR176/SRIX512/SRIX4K/CTS products.
Each SR176/SRIX512/SRIX4K/CTS device is a contactless memory, powered by a transmitted carrier radio wave at 13.56MHz. It contains a 176-bit (SR176), 512-bit (SRIX512), 4096-bit (SRIX4K) or 256-bit
(CTS) EEPROM, with memory mapping organized as blocks of 16 or 32 bits. It conforms to the ISO 14443-
B recommendation for the transfer of power and signals via radio transmission. The
Reader USB CRX14
Demokit V4.0
reader circuitry amplitude modulates (10% modulation) the data on the carrier using amplitude shift keying (ASK). The SR176/SRIX512/SRIX4K/CTS replies by load modulating the data on the carrier using the BPSK (Bit Phase Shift Keying) coding using the 847kHz sub-carrier. The data transfer rate in each direction is 106 Kbit/second.
The purpose of the
Reader USB CRX14 Demokit V4.0
program is to give an example of how the interfacing can be achieved. It does not allow the user to evaluate all of the different ISO14443 modes.
The
Reader USB CRX14 Demokit V4.0
gives access to the full memory mapping. It is possible to read and write into the selected SR176/SRIX512/SRIX4K/CTS device. This release of the demonstration software, differentiated for each SR176/SRIX512/SRIX4K/CTS, allows all of the product features to be exercised. The kit consists of:
– One CD-ROM
– One CRX14 board with I
2
C connector
– One USB Transceiver with USB cable
– Some SR176 and SRIX4K Samples
– Documentation.

Launching the Reader USB CRX14 Demokit V4.0 DemoKit Software
Connect the reader(s) to your PC. Run the
Reader USB CRX14 Version4.0.exe
to launch the program.
The program will detect all the readers automatically, and the main window appears at once (
Figure 4.
).
The various areas of this screen are described in detail in the remaining sections of this document.

UM0080 - USER MANUAL
USER INTERFACE
The User Interface is based on the Main Menus (
Figure 5.
). For the user, the most important entries are
Standard Mode
and
SuperUser Mode
.
Figure 5. Main Menus
Exit Menu
The Exit menu is used for stopping the demonstration software, and returning to the operating system.
SuperUser Mode Menu
The SuperUser gives you access to all of the commands of the SR176/SRIX512/SRIX4K/CTS.
Standard Mode Menu
In the Standard Mode you can
– access all the SR176/SRIX512/SRIX4K/CTS tags, in the field of the connected readers, along with the memory content of each tag.
– assign an image to each SR176/SRIX512/SRIX4K/CTS tag.
File Menu
In the File menu (
Figure 5.
) you can change the tag image folder, or change the background of the main
window. The background image should be a JPEG image file, and the recommended resolution for this is approximately 788 x 495 pixels.
For clarity, and convenience, it is recommended that the files in the image directory, or folder, should be named systematically, for example numbered continuously from
00.BMP
upwards. The content of each file must be in
.BMP
format, with a recommended resolution of about 120 x 120 pixels.
The tag assignments are written in the
TagData.ini
file, which is held in the
Tag
directory. Tags that are not listed in
TagData.ini
are considered as unassigned. Tags that have an image number assigned to them, but this number is greater than the number of files in the directory, are also treated as being unassigned. The tags with an image index equal to zero are also treated as unassigned.
If you wish to edit this file by hand, each line must contain the hexadecimal serial number of one tag, and the decimal number of the image that is assigned to it, separated by a equal sign “=”. For example:
[ImgIdx]
D0020CB3E3C74D04=4
D00208C5E804B690=2
D002102758774494=5
D0020CB3E3C755DE=4
D00208C5E8037F1F=1
D0020CB3E3C755DF=6
Erasing the contents of the
TagData.ini
file effectively removes all assignments.

ASSIGNING IMAGES TO TAGS
Place some SR176/SRIX512/SRIX4K/CTS memory tags in the field of the reader. The screen will appear as shown in
Figure 4.
, showing the tags that have been inventoried. Click with the left mouse button on
the tag to which you would like to assign a new image. A popup menu will appear, as shown in
Figure 6.
Figure 6. Assigning an Image to a Tag – Popup Menu

UM0080 - USER MANUAL
Here you can select the
Assign Picture Index
entry, to allow you to enter the number that corresponds to the image file in the selected folder. Alternatively, you can select the
Assign Picture Visually
entry, to allow you to assign a new image to the tag from those that are displayed graphically, in a window like that in
Figure 7.
. As another alternative, you can select the
Clear
entry, to clear the assigned image.

READING THE TAGS
Place some SR176/SRIX512/SRIX4K/CTS memory tags in the reader field. The screen will appear as shown in
Figure 4.
, showing the tags that have been inventoried, along with their corresponding images.
Double-click on a tag, to access its memory. A dialog box appears, as shown in
Figure 8.
In this dialog
box, the serial number and any previously saved text are displayed.
Figure 8. Tag Information Dialog Box
To modify the memory content, type your text in the text field, and click on the
OK
button. The tag’s memory will be updated.

UM0080 - USER MANUAL
SUPERUSER MODE
Choosing the
SuperUser
mode, in Main Menu, the screen will appear as shown in
Figure 9.
This gives you
access to all the commands that are available for the SR176/SRIX512/SRIX4K/CTS tags.
Figure 9. SuperUser Screen
First, you need to select, via the first combo-box, the physical CRX14 reader with which you want to work.
After this, you can choose whether you want to work with tags from Short Range (SR) family or with CTS tags. Then, you can start using the particular CRX14 functions and features. Depending on the precise state of the reader at any particular moment, and the responses that it has received from the tags, the user interface interactively offers the user relevant commands from the following list:
RF Off/On. By writing appropriate values in the Parameter register, of the selected CRX14 reader, the transmitted carrier radio wave is switched momentarily off and back on again.
Initiate. This button launches the anti-collision sequence of the Short Range contactless memory. This command is useful for speeding up the search for the Chip_ID, when there is only one tag in the reader field range.
Inventory. By writing into the Slot Marker Register, an automated anti-collision sequence is triggered between the selected CRX14 reader and the Short Range contactless memory that is presently accessible in the electromagnetic field. All the valid Chip_IDs that are received, as a result, are listed in the combobox, next to the
Select
button.
Reset Inventory. This command puts the Short Range contactless memory, that is presently in SELECT-
ED state, back in to the INVENTORY state.
Select. The active reader sends a SELECT() command, with the chosen Chip_ID. The Short Range contactless memory with the corresponding Chip_ID enters the SELECTED state, and each of the tags that do not match the Chip_ID are automatically put in the DESELECTED state.
11/14
UM0080 - USER MANUAL
Get UID. When receiving the GET_UID() command, the Short Range contactless memory sends back its
UID bytes in response.
Authenticate. By writing to the Authenticate Register, the complete authentication exchange is triggered between the active CRX14 reader and the STMicroelectronics secure Short Range contactless memory.
Read All. This command reads the whole memory content of the selected tag.
Reset Tag. This command brings the content of the user memory of the selected tag into the zero point state.
Read. This command reads the contents of one memory block of the selected tag. The memory block that is to be read is determined by the Address value.
Write. This command writes the new data, as supplied in the
Data Edit
box, into the selected tag’s memory, at specified address.
Erase. When receiving the ERASE() command, the CTS device fully erases the 16 bits of the addressed block, if available and not write/erase-protected.
Program. This command programs the data, as supplied in the
Data Edit
box, into the specified memory block of the selected CTS contactless memory.
Auto Find New Hardware. This button enables, or disables, the background routine. This routine monitors the plugging in and unplugging of USB devices. You should turn this feature
OFF
if you do not want to be disturbed for a while by irrelevant reader resets.
