1. Introduction
The TWN4 Slim is Elatec’s smallest compact & flat RFID reader – it’s
smaller than an ID-1 card. TWN4 Slim supports a huge range of LF and HF
technologies (125 kHz and 13.56 MHz). With the support of NFC and
Bluetooth Low Energy the reader supports mobile use cases for data
communication and authentication. It can be operated as a stand-alone unit
and connected using a standard cable with a micro USB plug to PCs and
other devices with USB interface. TWN4 Slim is perfectly suited to embed
it into machines and devices, and especially MFP printers. By using clip-on
covers, TWN4 Slim is mountable into printer chassis cavities and allow a
flat and even surface – invisible integration.

2. Getting Started
2.1 Operating mode
In order to start operating a TWN4 Slim, it simply has to be connected
directly to a host device.
2.2 Power Supply
Requirement for the external power supply unit:
- Limited Power Source according to IEC60950-1 or Limited Power
Source according to IEC60950-1 or
- PS2 classified IEC62368-1
- Short-circuit current < 8A
2.3 Enumeration
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.
2.4 Initialization
After powering up and enumeration 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.

2.5 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.
2.6 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.
2.7 Suspend Mode
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.

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 reason-able 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 deter-mined 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.
The product is FCC Rule Part 15B SDoC conform.
