REVISION HISTORY

INTENDED USE

TWN4 MultiTech 3 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, driver identification, POS integration and many more. Furthermore, TWN4 MultiTech 3 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 M BLE, it simply has to be connected directly to a host device.

POWER UP

Once TWN4 MultiTech 3 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.
