Transponder Reader TWN4 MultiTech 2
Elatec GmbH Page 2 of 12 Quick Start Guide Rev. 4 1. Introduction The transponder reader TWN4 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 125kHz and 13.56MHz. 2. Getting Started 2.1 Cable Connection In order to start operating a TWN4 transponder reader, it simply has to be connected to a host. 2.2 Power Up Once a TWN4 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.

As long as the device is not enumerated, it is entering a minimum power consumption mode, where both LEDs are turned off. 2.4 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 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.

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 (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.

Final Compliance of end product The integrator is responsible for the final compliance of the end product including this certified transmitter module. CFR 47 §15.101 give guidance in terms of applicable equipment authorization procedures of different end-products. Typically compliance to subpart 15 B (§15.107 and 15.109) Class A or B including verification of the subpart 15 C compliance (field strength of fundamental and out-of-band emissions) of the transmitter parameters apply. 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. if the TWN4 MultiTech2 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.
