IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
Example:
WP1UNC.00.01.02 allows two channels for a read attempt.
RP1UNC.00.00 reads out the number of channels set.
Search Algorithm Cancellation Criteria "number of tags to find" NT
Parameter NT specifies the number of tags in the measurement range that the read/write head
searches for. Each command is repeated in accordance with the parameters Transmission
Power (PT), Transmission Channel (CD) or Number of Channels (NC), and Number of
Attempts (TA) (see chapter 6.2). If the number of tags found during the repeat operations
reaches or exceeds the NT value, all further runs are canceled. The command is canceled, and
the data is output.
If the number of tags is set to 255 (= .FF), the function is deactivated. This parameter does not
affect "enhanced" commands, but only "single" commands.
ParamTyp:
Default:
Value range:
Example:
The value WP1UNT.00.01.05 sets the number of tags in the measurement range for which the
read/write head searches to 5.
RP1UNT.00.00 outputs the set value.
Transmission Power "Power Transmit" PT
This parameter sets the transmission power in mW or reads out the transmission power set.
ParamTyp:
Default:
Value range:
Example:
WP1UPT.00.02.00.32 sets the transmission power to 50 mW
RP1UPT.00.00 reads out the transmission power currently set
Higher detection range if you increase the transmission power.
Possible excessive detection ranges if you increase the transmission power.
Adjacent read/write heads might be affected if the range increases.
Tip
The highest transmission power does not necessarily lead to the largest read range. Vary the
transmission power to achieve the optimum read result.
Note
You can operate the read/write head only with internally specified transmission power. You can
use the command WP1UPT.00.02.xx.xx in the software to enter any transmission power within
the specified range of values. The read/write head automatically sets the transmission power to
the next lowest value available. Any entries outside the specified value range are returned as
errors. Command RP1UPT.00.00 allows you to read out the power value that is currently set.
