INTENDED USE
TWN4 Palon Square M LF HF is a versatile OEM PCB for integration into third-
party products and devices. It supports enhanced
interfaces, especially RS-485. The new single PCB module inherits all
advantages and tool support of the ELATEC TWN4 family.
Although being a general-purpose PCB module, it is optimized for time
attendance and access control.
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 Palon Square M LF HF, it simply has to be
connected directly to a host device.
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 norms listed in the respective declaration(s) of conformity
- Short-circuit current < 8 A
Once TWN4 Palon Square M LF HF is connected to the host, it detects the type of communications cable (e.g. USB), with which it is connected 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 like 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
the module is searching for a transponder continuously.
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 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 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 to normal operation mode, this is also signaled via the USB
bus. Therefore, the reader module will resume normal operation too.
COMPLIANCE STATEMENTS
EU
TWN4 Palon Square M LF HF is in compliance with the EU directives and
regulations as listed in the respective declaration of conformity.
RF EXPOSURE COMPLIANCE
RF exposure statement (mobile and fixed devices)
This device complies with the RF exposure requirements for mobile and fixed
devices. However, the device shall be used in such a the manner that the
potential for human contact during normal operation is minimized.
