5. Data Transmission between Ha-VIS RFID RF-R400 and Host
5.1 Configuration Commands and Control Commands

5.2 Host Commands

12
Six different ways of data transmission between RF-R400 and host (terminal, PC) are possible.
The Host Commands, Buffered Read Mode, Scan Mode and Notification Mode are used
for the data exchange between transponder and host, whereas the Configuration Commands
and the Reader Control Commands serves for adapting the reader parameters to the
individual range of applications. The following chart shows which method of data transmission
is supported by which interface:

just for testing not recommended for real applications
This method of data transmission is used for Reader configuration and the diagnosis via the
different Hardware Interfaces of the reader.
The reader-configuration parameters will be stored in the Reader memory. To store the current
configuration during a power down of the reader the reader-Configuration has to be stored in
the EEPROM. After power up the reader reads the configuration out of the EEPROM.
The reader control is immediately processed and the response from the Reader contains status
or data information of the control command.
Host (Terminal / PC / ....)
parameter- / control command
The host commands provide the exchange of data between a host and transponders via the
reader as long as the transponder remains in the detection range of the reader.
Note
During the writing of data to a transponder, it must be ensured that the transponder is located
within the detection range of the reader for the duration of the entire process. If the transponder
is removed from detection range of the reader during a writing process, this will cause a loss of
data.
