2INTENDED USE
The contactless RFID readers and modules of the ELATEC TWN4 MultiTech 2 LEGIC family are a direct enhancement of the TWN4
MultiTech LEGIC readers with the same form factors (PCB modules and desktop readers with housing). During the development of
the TWN4 MultiTech 2 LEGIC family, special emphasis has been placed on optimizing the HF performance (13.56 MHz). Compared
to the predecessor TWN4 MultiTech LEGIC, the read range could be increased by more than 50% for LEGIC transponders and even
doubled for some HF transponders.
TWN4 MultiTech 2 LEGIC M key features include a powerful SDK for writing apps that are executed directly on the module, the
possibility to upgrade the firmware in the field, a direct chip-commands support, and a powerful BLE module. Additionally, the module
can simultaneously read more than 60 RFID technologies from low (LF) and high frequency (HF) bands, including NFC. This gives the
option to select as many of the technologies required instead of being forced to select just a few ones.
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 comply with the safety information
given in this document, is considered improper use. ELATEC excludes any liability in case of improper use or faulty product
installation.

5MODE OF OPERATION
The mode of operation described in the following chapter is based on a standard ELATEC RFID reader module equipped with two
LEDs. Depending on your product (number of LEDs, installed firmware, etc.) and in case the product settings have been modified with
the AppBlaster tool, the information below might differ from your product configuration when in operation. In particular, the color and
sequence of the LEDs on your product might be different.
5.1 OPERATING MODE
In order to start operating TWN4 MultiTech 2 LEGIC M, it simply has to be connected directly to a host device.
5.2 POWER UP
Once TWN4 MultiTech 2 LEGIC M is connected to the host device, 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:
•A version string is sent via RS-232 to the host device.
•A 5 V external power supply is required and must meet the following conditions:
oPS2 classified power source according to IEC 62368-1
oShort-circuit current < 8 A
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 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 module is
searching for a transponder continuously.
5.6 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.

© 2023 ELATEC GmbH – TWN4 MultiTech 2 LEGIC M user manual – DocRev01 – EN – 07/2023 Page 10 of 14
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 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.
