This article is a Step-by-Step guide to configuring the Elatec TWN4 with the AppBlaster Tool from Elatec.
The AppBlaster Software discussed in this article will only run on Windows. MAC is not supported.
you will see a green light on the TWN4 and no further action is required in this section
This part assumes you’re connecting the reader for the first time and the driver has
not installed correctly when you attach the card reader to your PC
If you see a red light or no lights at all you may have an issue with the driver, check the driver
in the Device Manager
Open Device Manager and check for warnings in the Other Devices or Keyboards sections
Right click on the mouse then select Update Driver Software
Select Browse my computer for driver software
Navigate to the driver directory in the TWN4DevPack3xx folder on your PC.
Highlight the folder then click OK to install the driver
Once installed you should hear a beep and a green light should also be visible from the card
Check Device Manager to see if the warning icon has disappeared, if there are no warnings
you should be good to go…
To restrict the cards accepted on the TWN4, click on AppBlaster.exe in the TWNDevPack3
You will be shown the following screen:
the example below:
If you’re unsure of the type of card/s you have, please see the section: Tracer Mode later in
Make sure you save each transponder type by clicking Add, then confirm it’s listed in the “Ac
tive Transponder Types” window.
If you need to delete any transponders from the “Active Transponder Types” window, you
can do this by highlighting the transponder and clicking Remove.
Once you have added the transponders needed, click the plus icon next to “Transponder
Types” in the Action Items window.
You’ll be shown each transponder type selected earlier….click the plus icon next to each
transponder in the Action Items window and configure the following settings on each:
Click the transponder and confirm the card UID length of the card in Accept UID with
number of bits:
Click Bit Manipulation and select the appropriate Bit and Byte order, if applicable.
Click Output Format , choose the output settings (Bits, Format and Length) for your selected
card and click Add Field
Click Type of USB (“Template”) and select the Firmware Core Module Keyboard V3.xx
App Standard V2.xx, then click Select Template
You can change settings in the last 4 menus of the Action Items window, however for this
basic setup they can be left unchanged.
Click Create Image and when finished click Program Image to send the completed
configuration to the card reader.
Test the cards on the reader to confirm the output is correct for your needs, then click Save t
o save the configuration to your PC.
Tracer Mode shows the Card Type, Bit Length and Hex number all in the one scan, as shown in
the image below:
As the image shows, 11 separate card have been read and the corresponding information is
To put the card reader into Tracer Mode:
- Connect the card reader to the Laptop/PC
- Run AppBlaster v3.xx
- Click on Program Firmware Image
Select TWN4_CKx310_TRC217_Tracer.bix or similar
Click Program Image and wait for the programming to finish (seen in the Messages window)
Open Notepad and test the cards to get the information as seen above.
Once the card type is known, you can now go ahead and customize the card with the procedure
listed earlier in the manual. See: Configuring the reader - (basic setup)
from the card.
- Connect the TWN4 to your PC.
- Start the AppBlaster application and click Program Firmware Image.
- Click Open then wait for the firmware to finish installing.
Open Notepad or a similar program and place the cards one at a time on the TWN4.
Leave the card on the TWN4 until the scan is finished, the last line of the output will be "End" as
When you have retrieved all of the information from the cards, email it to Copy Monitoring along
with what you need to be output from the TWN4 reader.
- Create an empty directory on your hard disk
- Unzip the entire contents of the zip file into this empty directory
- The program "AppBlaster" can be found in the top directory of the TWN4 developer pack
value, either 0 or 1.
Although computers usually provide instructions that can test and manipulate bits, they generally
are designed to store data and execute instructions in bit multiples called bytes.
In most computer systems, there are eight bits in a byte.
The value of a bit is usually stored as either above or below a designated level of electrical
charge in a single capacitor within a memory device.
A byte is a unit of data that is eight binary digits long.
A byte is the unit most computers use to represent a character such as a letter, number or
Each byte can hold a string of bits that need to be used in a larger unit for application purposes.
For example, the stream of bits that constitute a visual image for a program that displays images
or the string of bits that constitutes the machine code of a computer program.
FAQs and Tips
output found Papercut is 39343837373035
Try using the ascii-enc converter to remove the 3's
In Papercut, select Options > Config editor (advanced) and search for ext-d
Enter ascii-enc into the associated field and click Apply, test again and check
the resulting output it will now be 9487705.
Need a hex to decimal converter or decimal to hex converter ?
As an example: hex to decimal will convert: 946ebd28 to 2490285352 and decimal
to hex will convert 2490285352 to 946ebd28
In Papercut, select Options > Config editor (advanced) and search for ext-d
Enter hex2dec or dec2hex into the associated field and click Apply, test

Elatec’s TWN4 MultiTech is a contactless RFID reader/writer and a direct enhancement of the TWN3 with the same mechanical dimensions (OEM PCB and Desktop Housing). The TWN4 MultiTech family of transponder readers and writers allows users to read and write to almost any 125 kHz / 134.2 kHz and 13.56 MHz tags and/or labels. TWN4 MultiTech also supports all major transponders from various suppliers like ATMEL, EM, ST, NXP, TI, HID, LEGIC, and ISO standards like ISO14443A/B (T=CL), ISO15692 and ISO18092/ECMA-340 (NFC)
Key features of the TWN4 MultiTech include a powerful SDK for writing Apps which are executed directly on the reader, infield upgradeable firmware, direct chip-commands support, and additional interfaces for the OEM PCB version. TWN4 MultiTech simultaneously reads more than sixty RFID technologies from both the low frequency (LF) and high frequency (HF) bands, including NFC. This provides the option to select as many of the technologies required instead of being forced to select just a few like most other readers.
In addition, TWN4 MultiTech can also be used as a diagnostic tool by installing the card analyzer application called TechTracer. It now becomes capable of identifying the card type, data length, and unique identification number. This eliminates the requirement to physically send cards off-site for identification while potentially saving weeks of waiting for the diagnosis. Analyzing the card in front of the end customer demonstrates that the card can be read, which is normally a requirement of a proof-of-concept.
