4.3 Description of the individual registers
4.3.1 Cfg_Delaytime
The repeat rate of the ID message of the same transponder can be defined by using the con-
figuration register Cfg_Delaytime. It can be set to any interval between 50ms and 13 seconds. If
the transponder is read again after this time (Delay time), in master mode the ID will be output
once more at the serial interface, independent of how often it is detected within the time interval.
In slave continuous mode, renewed addition to the internal buffer will not take place until the de-
lay time has elapsed, independent of how often it is detected within the time interval. In slave
request mode the delay time is ignored.

4.3.2 Cfg_Format
ID message:
The configuration register Cfg_Format is used for setting the output format of the transponder
ID. The transponder data decoded as per ISO 11784 can be displayed in ASCII format directly
on simple output terminals. For special application two further ASCII formats are available
which are transmitted without any checksum. They are both finished by CR LF. With the raw
data format however the complete transponder data, including control and back-up data, are
provided with CRC or parity check components. In addition, intermediate steps during data con-
version can also be selected, such as the 'transponder byte structure' or the binary notation for
transponder data decoded as specified in ISO 11784. For a detailed description of ID message,
see chapter 5.9.
In slave request mode an ID is always output only at the moment of detection, not at the time
when the transponder leaves the detection area.

4.3.4 Cfg_Node
If the reader is used in a network with several readers, it is possible to give the reader an indi-
vidual network address by using the Cfg_Node register.

4.3.5 Cfg_RF
In applications where for example only one transponder type is used, the configuration register
Cfg_RF can be used to hide other types supported by the reader (FDX-B, HDX, H4002) and
thus speed up acquisition.
