INTENDED USE
TWN4 MultiTech 3 M LF integrates RFID (125 kHz) capabilities into a compact
but powerful reader. Its reduced size combined with excellent read/write
performance makes it the perfect reader for all applications where small size
and full performance matters, e.g. print solutions, healthcare applications,
driver identification, POS integration, and much more. Furthermore, TWN4
MultiTech 3 M LF provides access to most common host interfaces such as USB,
serial (TTL), or I²C which are readily accessible through an onboard
connector.
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.

TECHNICAL DATA
The reader module is equipped with the following antenna:
TWN4 MultiTech 3 M LF – bottom view
LF antenna (125 kHz)
Dimensions: 49 x 34 mm / 1.93 x 1.34 inch
Number of turns: 3
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 TWN4 MultiTech 3 M LF, 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 TWN4 MultiTech 3 M LF 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 the built-in transponder-reader logic. The green LED is turned on permanently. Some reader modules need some kind of initialization, which is performed in this step. After successful initialization, the device sounds like 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 supports the USB suspend mode. If the USB host is signaling to 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 normal operation, too.
