Explanation of abbreviations used in this user manual  
 
RF: 

Radio Frequency (in this case the long-wave band) 

RFID: 

Radio Frequency Identification. Method to transmit data without contact us-
ing transponders. 

Reader: 

A device which is able to communicate with transponders using an internal 
or external antenna. The reader generates a high frequency field in order to 
get the data of a transponder. The received data is transmitted by an inter-
face to an external controller (e.g. PC etc.). 

Transponder: 

Data carrier for RFID applications, available in various models and types. 

Raw data: 

Complete data contents of a transponder, which means ID and additional in-
formation (for example header or trailer). 

ID: 

Identification number of a transponder. 

ISO 11784/85: 

International standard regarding the use of RFID technology in the identifica-
tion of animals; it defines the transponder types to be supported and the ID 
notation. 

FDX: 

Transponder type, which transmits its data while the HF field, is on (full du-
plex). 

FDX-B: 

FDX transponder with 128 bits of raw data, ID notation in compliance with 
ISO 11784/85. 

HDX: 

Transponder type, which transmits its data directly after HF field, goes off

 

(half duplex). 104 bits of raw data, ID notation in compliance with ISO 
11784/85. 

Master mode: 

Read mode in which the reader works as master. The reader makes field on 
and off permanently and transmits received transponder data automatically. 

Slave request: 

Read mode in which the field is normally off. The reader makes field on and 
off only after a request by the controller. If a transponder was read during 
activation time the ID is transmitted to the controller. 

Slave continuous:  Read mode in which the reader makes field on and off permanently. The 

reader transmits received transponder data only after a request from an ex-
ternal controller.
