Readers
Data transfer rate / volume
The transponder and reader communicate through inductive alternating fields, also referred to
as antenna fields.
The transmittable data volume between reader and transponder depends on
• the speed at which the transponder moves through the transmission window of the reader.
• the length of the transmission window,
• the transponder type used (RF300- / ISO 15693- (MDS D)/ ISO 14443 transponder (MDS E)),
• the memory type (FRAM, EEPROM; with RF300 transponders).
Note
Output power of the readers
The output power of the readers at the antenna (antenna input) does not correspond to the
transmit power or radiated power of the device.
Physically, in an HF RFID system in the 13.56 MHz spectrum, the transmit power is hardly
measurable because the physical process is induction (magnetic field) between the reader's
antenna and the transponder's antenna. The measurable physical quantity is the field strength
in amperes per meter (A/m).
ISO 15693 functionality
With all readers of the RF300 family, you can use ISO 15693 transponders. Note that the readers
for RF300, ISO 15963 or ISO 14443 operation must have parameters assigned. The parameter
assignment done with the aid of the RESET frame (INIT-Run).
For more detailed information on software parameter assignment refer to the manuals.
