REVISION HISTORY

 INTENDED USE

The TWN3 MIFARE RFID reader is designed for easy integration into various applications. This device supports either USB or RS232 communication just in dependence on the connection cable and is available as a ready-to-connect desktop reader in a slim line black or white housing. The reader can be programmed with a scripting language for autonomous execution of even complex commands like login procedures, increment/decrement functions and many more. 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 observe the safety information listed in this document, will be considered misuse and will void the warranty. ELATEC is not responsible for any damage or injuries resulting from any misuse of the product.

 MODE OF OPERATION

OPERATING MODE

In order to start operating TWN3 MIFARE, it simply has to be connected directly to a host device.
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 MIFARE 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. The result of this detection is signaled via the two LEDs:

•   USB cable: red LED flashes once.
• RS-232 cable: green LED flashes once. This flash is hidden by the directly following permanent one of the green LED.

In case of RS-232: Additionally, the RS-232 is sending a version string via RS-232 to the host.
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.
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 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, which is similar to a “plug & play” sound.
NORMAL OPERATION
As soon as the device has completed the initialization, it is entering normal operation. During normal operation, the device is searching for a transponder continuously.
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. 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 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.
SUSPEND MODE
The USB version of the reader supports the USB suspend mode. If the USB host is signaling suspend via the USB bus, then 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.
