INTENDED USE

The TWN3 LEGIC NFC M RFID reader module is designed for easy integration into various applications. This device supports either USB or RS-232 communication just independent of the connection cable and is available as an OEM board (PCB) without housing for direct integration into embedded applications. The reader module can be programmed with a scripting language for autonomous execution of even complex commands like login procedures, increment/decrement functions and many more.
TWN3 LEGIC NFC M is intended to be used as an RFID solution for secure access and data communication in different applications like printing, human-machine interfaces, and other industrial applications.
The product is intended to be integrated into a host device.
Any use other than the intended use described in this section, as well as any failure to observe the safety information listed in this document, will be considered misuse and will void the warranty. ELASTIC is not responsible for any damage or injuries resulting from any misuse of the product.

For more information, refer to the related product data sheet or other technical documents.

MODE OF OPERATION

5.1 OPERATING MODE
In order to start operating TWN3 LEGIC NFC M, it simply has to be connected directly to a host device.
5.2 POWER-UP
In case of an external power supply unit is used, the following requirements must be satisfied:

•  Limited power source according to the safety norms listed in the respective declaration(s) of conformity
• Short-circuit current < 8 A Once TWN3 LEGIC NFC M is connected to the host, it detects the type of communications cable (e.g. USB or RS-232), with which it is connected to the host. In the case of RS-232: Additionally, the RS-232 is sending a version string via RS-232 to the host.

5.3 ENUMERATION
This is only applicable for the USB version: 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, where both LEDs are turned off.
5.4 INITIALIZATION
After powering up and enumeration (in USB mode), the device is turning on its built-in transponder-reader logic. The green LED is turned on permanently. Some RFID reader modules 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 module has completed the initialization, it is entering normal operation. During normal operation, the reader module is searching for a transponder continuously.
5.6 DETECTION OF A TRANSPONDER
If a transponder is detected by the reader module, the following actions are performed:

• Send the ID to the host. By default, the USB device sends by emulating keystrokes of a keyboard. An RS-232 device sends the ASCII code of an ID.
•  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 module 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 USB version of the reader module supports the USB suspend mode. If the USB host is signaling to suspend via the USB bus, then the reader module 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 module will resume to normal operation too.

COMPLIANCE STATEMENTS

6.1 EU
TWN3 LEGIC NFC M is in compliance with the EU directives and regulations as listed in the respective declaration of conformity.
6.2 RF EXPOSURE COMPLIANCE
RF exposure statement (mobile and fixed devices)
This device complies with the RF exposure requirements for mobile and fixed devices. However, the device shall be used in such a manner that the potential for human contact during normal operation is minimized.
