Operation
Set the polarization according to the read/write tag used (see chapter 4.3.3). You can achieve a
better detection range if the polarization of the read/write head corresponds to the polarization
of the read/write tag.
Set the polarization to combined mode if the orientation of the tag is not known. In combined
mode, first horizontal polarization and then vertical polarization is used for each read/write
attempt. This achieves the same results as when circular polarization is used. The duration of
the read/write operation is extended in combined mode.
CD Transmission Channels
Frequency Access Method Programmable frequency list:
This parameter sets the number and sequence of transmission channels or reads out the
number and sequence of transmission channels.
Frequency Access Method Frequency hopping spread spectrum:
This parameter reads out the number and sequence of transmission channels for the
frequency hopping spread spectrum.
ParamTyp:
Default:
Value range:
Example:
WP1UCD.00.04.07.0A.04.0D defines the sequence 7, 10, 4, and 13 as the permitted
transmission channels
WP1UCD.00.01.0A allows the read/write head to use only transmission channel 10
RP1UCD.00.00 reads out the sequence of permitted transmission channels
Tip
If you have parameterized several transmission channels with the parameter CD, the read/write
head executes each write or read command on all defined transmission channels sequentially
according to the defined sequence. If several additional transmission power values are
parameterized (see "Transmission Power "Power Transmit" PT" on page 54), all set
transmission powers are executed on each transmission channel for each read or write
command. See chapter 6.2.
Number of Unsuccessful Attempts until Status 5 "Enhanced Status 5" E5
This parameter sets the number of unsuccessful read/write attempts until a status 5 is output for
an enhanced command, or outputs the number.
Status 0 and status A depend on this parameter, and are output immediately.
ParamTyp:
Default:
Value range:
Example:
WP1UE5.00.01.05 sets the number to 5 unsuccessful read/write attempts until a status 5 is
output
RP1UE5.00.00 outputs the number
If the number of read/write attempts is reduced:
