2INTENDED USE
The devices of the TWN4 USB Front Reader family are an excellent solution for any RFID-based applications that require a direct and
simple connection per USB. All readers are available with an NXP or LEGIC frontend and support RFID, NFC and Bluetooth Low
Energy (BLE) technologies. In addition, the patented USB connector on the rear side can be turned to 90°, which enables a quick and
easy installation into any host system equipped with a USB port. Thanks to their compact form and enhanced read/write performance,
the readers are particularly appropriate as a secure printing solution, but also for Single-Sign on and healthcare applications.
Key features of the TWN4 USB Front Reader include a USB hub on the front side that can be deactivated via device driver, a powerful
SDK for writing apps that are executed directly on the reader and an integrated BLE module. Additionally, the reader can read more
than 60 RFID technologies from low (LF) and high frequency (HF) bands, including NFC. This gives the option to select as many of
the technologies required instead of being forced to select just a few ones.
The product is for indoor use and may not be used outdoor.
Any use other than the intended use described in this section, as well as any failure to comply with the safety information
given in this document, is considered improper use. ELATEC excludes any liability in case of improper use or faulty product
installation.

5MODE OF OPERATION
The mode of operation described in the following chapter is based on a standard ELATEC RFID reader equipped with two LEDs.
Depending on your product (number of LEDs, installed firmware, etc.) and in case the product settings have been modified with the
AppBlaster tool, the information below might differ from your product configuration when in operation. In particular, the color and
sequence of the LEDs on your product might be different.
5.1 OPERATING MODE
In order to start operating TWN4 USB Front Reader, it simply has to be connected directly to a host device. TWN4 USB Front Reader
is not designed to be operated with any extension lead.
5.2 POWER UP
In case of an external power supply unit is used, the following requirements must be satisfied:
•PS2 classified power source according to IEC 62368-1
•Short-circuit current < 8 A
5.3 ENUMERATION
Once the device has been powered up, it is waiting for completion of the enumeration by the USB host. As long as the device is not
enumerated, it is entering a minimum power consumption mode.
5.4 INITIALIZATION
After powering up and enumeration, the device is turning on the built-in transponder reader logic. The green LED is turned on
permanently. Some RFID readers need some kind of initialization, which is performed in this step. After successful initialization, the
device sounds a short sequence, which consists of a lower tone followed by a higher tone.
5.5 NORMAL OPERATION
As soon as the reader has completed the initialization, it is entering normal operation. During normal operation, the reader is searching
for a transponder continuously.
5.6 DETECTION OF A TRANSPONDER
If a transponder is detected by the reader, following actions are performed:
•Send the ID to the host. By default, the USB device sends by emulating keystrokes of a keyboard.
•Sound a beep.
•Turn off the green LED.
•Blink the red LED for two seconds.
•Turn on the green LED.
Within the two seconds timeout, where the red LED is blinking, the transponder, which just has been recognized will not be accepted
again. This prevents the reader from sending identical IDs more than one time to the host. If during the two seconds timeout of the red
LED a different transponder is detected, the complete sequence restarts immediately.

5.7 SUSPEND MODE
The reader supports the USB suspend mode. If the USB host is signaling suspend via the USB bus, the reader is turning off most of
its power consuming peripherals. During this operation mode, no detection of transponders is possible and all LEDs are turned off.
Once the host is resuming to normal operation mode, this is also signaled via the USB bus. Therefore, the reader will resume to normal
operation too.
