VALUE
Range of values: 0.5 ... 33
Increment: 0.25
Radiated power of the antenna in
[dBm].
Bytes 1 and 2 are not used, byte 3
represents the integer and byte 4
the decimal place.
Example: A radiated power of
10.25 dBm represents a "VALUE"
of "0x0A19".
Range of values: 0 ... 255
Threshold value for RSSI.
Transponders with lower values
are discarded. Value without unit
without a direct relationship with
the radiated power.
Range of values: 0 ... 255
Difference for RSSI values.
Transponders with lower values
relative to the transponder with
the highest RSSI value are dis-
carded. Value without unit without
a direct relationship with the radi-
ated power.
Range of values: 0, 1, 2, 4
Polarization of the antenna (for
intelligent antennas e.g. internal
antenna RF685R)
• 0: default, undefined
• 1: circular
• 2: vertical linear
• 4: horizontal linear
Input is bit coded. Combinations
are possible (adding values).
