5 Mode of Operation

The mode of operation described in this 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 if 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

To start operating TWN4 MultiTech Nano M, it simply needs to be connected directly to a host device.

5.2 Power Up

If an external power supply unit is used, the following requirements must be satisfied:

• Limited power source according to the safety standards listed in the respective declaration(s) of conformity.
• Short-circuit current < 8A.

Once TWN4 MultiTech Nano M is connected to the host device, it detects the type of communications cable (e.g., USB) with which it is connected 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 turns on the 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.

5.5 Normal Operation

As soon as the reader module has completed the initialization, it enters 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.
• Sound a beep.
• Turn off the green LED.
• Blink the red LED for two seconds.
• Turn on the green LED.

Within the two-second timeout, where the red LED is blinking, the transponder that was just 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-second timeout of the red LED a different transponder is detected, the complete sequence restarts immediately.

5.7 Suspend Mode

The USB version of the RFID reader module supports the USB suspend mode. If the USB host is signaling suspend via the USB bus, the reader module turns 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 resumes to normal operation mode, this is also signaled via the USB bus. Therefore, the reader module will resume to normal operation too.

6 Compliance Statements
