Elatec TWN4 Palon Compact LEGIC Transponder Reader
Introduction
The transponder reader TWN4 Palon Compact LEGIC is a device for reading and writing RFID transponders. There are different versions of TWN4 devices available, which cover a large range of transponder types both in the frequency range of 125 kHz and 13.56 MHz.
Getting Started
Cable Connection
In order to start operating a TWN4 Palon Compact LEGIC transponder reader, it
simply has to be connected to a host.
Power Up
Once a TWN4 Palon Compact LEGIC reader is connected to the host, it detects
the type of communications cable (USB or RS232), with which it is connected to
the host.
Additionally, the RS232 is sending a version string via RS232 to the host.
Enumeration (USB Only)
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 transponder 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.
Normal Operation
As soon as the device has completed the initialization, it is entering normal
operation. During normal operation the device is searching for a transponder
continuously.
Detection of a Transponder
If a transponder is detected by the reader, following actions are performed
- Send the ID to the host. By default, the USB device sends by emulating keystrokes of a keyboard. A RS232 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 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 (USB Only)
The USB version of the transponder reader supports the USB suspend mode. If
the USB host is signaling suspend via the USB bus, the transponder reader 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 transponder reader will resume to normal
operation, too.
List of Antennas
Power Supply
In case of USB connection, the input voltage is 4.3V to 5.5V.
If the device is supplied via the terminal block, the input voltage is 9V to
30V.
Pinout
External Antenna
Please note: Connecting an antenna to the UMCC connector is not included in the approvals of the device. In this case, the device requires separate approval with that specific antenna.
Compliance statements
RF module
USA (FCC)
(RF module)
Compliance statement:
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Modification of equipment:
The instruction manual of the host shall include the following statement:
Changes or modifications made to this equipment not expressly approved by the
party responsible for compliance may void the FCC authorization to operate
this equipment.
Information to the user:
(The instruction manual of the host shall include the following statement) A
compliance statement as applicable, e.g., for devices subject to part 15 of
CFR 47 as specified in §15.19(a)(3), that the product complies with the rules;
and the identification, by name, address and telephone number or Internet
contact information, of the responsible party, as defined in §2.909. The
responsible party for Supplier’s Declaration of Conformity must be located
within the United States.
CANADA (ISED)
This device complies with Industry Canada’s license-exempt RSSs. Operation is
subject to the following two conditions:
- This device may not cause interference; and
- This device must accept any interference, including interference that may cause undesired operation of the device.
Host device
USA (FCC)
FCC notes for a host subject to SDoC:
For a host device assembled with the certified module and subject to 47 CFR
Part 15, the following statements have to be included in the user manual and
the host device has to be labelled as noted below. If the host device is
subject to other authorization procedures or parts, the appropriate
requirements of these authorization procedures or parts apply.
Important note:
OEM integrator is still responsible for the FCC compliance requirements of the
end product, which integrates this module. Appropriate measurements as
described in “KDB 996369 D04 Module Integration Guide” and, if applicable,
additional equipment authorization of the host device have to be addressed by
the integrator/ manufacturer
The end device must be labeled with:
Contains FCC ID: WP5TWN4F11
For class B devices:
FCC §15.105 (b):
Note: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the Receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
For class A devices:
FCC §15.105 (b):
NOTE: This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the
user will be required to correct the interference at his own expense.
Special accessories:
Where special accessories such as shielded cables and/or special connectors
are required to comply with the emission limits, the instruction manual shall
include appropriate instructions on the first page of the text describing the
installation of the device.
Simultaneous transmission:
When the host product supports simultaneous-transmission operations the host
manufacturer needs to check if there are additional RF exposure filing
requirements due to the simultaneous transmissions. When additional
application filing for RF exposure compliance demonstration is not required
(e. g. the RF module in combination with all simultaneously operating
transmitters complies with the RF
exposure simultaneous transmission SAR test exclusion requirements), the host
manufacturer may do his own evaluation without any filing, using reasonable
engineering judgment and testing for confirming compliance with out-of-band,
restricted band, and spurious emission requirements in the simultaneous-
transmission operating modes. If additional filing is required please contact
the person at ELATEC GmbH responsible for certification of the RF module.

Important note:
OEM integrator is still responsible for the ISED compliance requirements of
the end product, which integrates this module. Appropriate requirements as
described in RSS-GEN have to be fulfilled by the integrator/ manufacturer.
Labeling requirements for Host device:
For Host devices subjected to ICES-003, the appropriate labeling requirements
apply.
