MODE OF OPERATION

The mode of operation described in the following chapter is based on a standard ELASTIC 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 M LF HF, 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 standards listed in the respective declaration(s) of conformity
• Short-circuit current < 8 A

Once TWN4 MultiTech 2 M LF HF 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 device.
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 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 the 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 RFID reader module supports the USB suspend mode. If the USB host is signaling to 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 normal operation mode, this is also signaled via the USB bus. Therefore, the reader module will resume normal operation too.
