MOBY U Distance limitation
Normal transmit power
0x05 = 0.5 m
0x0A = 1.0 m
0x0F = 1.5 m
0x14 = 2.0 m
0x19 = 2.5 m
0x1E = 3.0 m
0x23 = 3.5 m
Intermediate values in steps of 0.1 m are possible (0x02, 0x03, ..., 0x23)

MOBY D Transmit power from 0.5 W to 10 W in increments of 0.25 W
Only effective with SLG D10S; a power of 1 W (04 hex) is set for SLG D11S /
D12S and cannot be changed.

RF300 The reader is basically intended for multitag operation, which is, however, not
currently released.
Maximum number of transponders that can be processed at the same time in the
antenna field. Currently permitted values "1".
RF600 Number of transponders expected in the antenna field.
Permitted values:
0x01 ... 0x28 for RF620R
•
0x01 ... 0x50 for RF630R with 2 antennas (SET-ANT = 0x03)
•
0x01 ... 0x28 for RF630R with 1 antenna (SET-ANT = 0x01 or SET-ANT =
•
0x02).
The value specified here defines the maximum expected number of transponders
to be read (EPC-ID) in the inventory.
The value does not restrict the number of transponders to be processed in the
antenna field. To allow an efficient inventory of transponders in the antenna field,
the values given here should not deviate from the maximum number of transpond-
ers expected in the antenna field by more than approx. 10%.

3.5 Programming the Ident profile
Reduced output power
1)
0x85 Set reduced transmit power when several
readers are positioned close together or
0x8A
when transponders which are located in
0x8F
the vicinity of a reader are detected later
0x91
or no longer.
0x99
Disadvantage: The field lobe becomes
smaller and there is less time for commu-
0x9E
nication or positioning must be more
0xA3
precise.
