INTENDED USE
TWN4 MultiTech 3 LEGIC M BLE integrates RFID (125 kHz and 13.56 MHz), NFC and
Bluetooth Low Energy capabilities into a compact but powerful reader. Its
reduced size combined with optimized 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 LEGIC M BLE
provides access to most common host interfaces such as USB, serial (TTL) or
I²C which are readily accessible through an on-board 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. 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 TWN4 MultiTech 3 LEGIC M BLE, 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 LEGIC M BLE 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 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 the
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.
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.
DETECTION OF A TRANSPONDER
If a transponder is detected by the reader module, 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.
SUSPEND MODE
The USB version of the reader module supports the USB suspend mode. If the USB host is signaling suspend via the USB bus, 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.
