Refer to your product data sheet for more information.
MODE 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 ELATEC 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.
4.1 OPERATING MODE
To start operating TWN4 Palon Compact S M LEGIC (“reader module”), it simply has to be connected directly to a host device.
4.2 POWER UP
Once the reader module is connected to the host device, it detects the type of communications cable (USB), with which it is connected to the host.
4.3 ENUMERATION
Once the reader module has been powered up, it waits for completion of the enumeration by the USB host. As long as the reader module is not enumerated, it is in a minimum power consumption mode, where both LEDs are turned off.
4.4 INITIALIZATION
After powering up and enumeration, the reader module turns on the built-in transponder reader logic.
The green LED is turned on permanently. Some RFID modules need some kind of initialization, which is performed in this step. After successful initialization, the reader module sounds a short sequence, which consists of a lower tone followed by a higher tone.
4.5 NORMAL OPERATION
As soon as the reader module has completed the initialization, it enters the normal operation mode.
During normal operation, the reader module searches for a transponder continuously.
4.6 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 reader module 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 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.
4.7 SUSPEND MODE
The USB version of the reader module supports the USB suspend mode. If the USB host signals 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.
