IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
If the country identifier RC = 01 (= 4 channels), RP1UMF.00.00 returns the response
01.63.64.67.65
Explanation of the response:
<Status> = 0
<ChanNo> = 1
<PCh04> = .63 = 99
<PCh07> = .64 = 100
<PCh10> = .67 = 103
<PCh13> = .65 = 101
Number of Channels NC
Frequency Access Method Frequency hopping spread spectrum:
Parameter NC indicates the number of channels on which a write or read attempt is performed.
If the value 4 is set, the read/write head attempts to read the tag on 4 different frequencies
when a read command is given. The parameter can be read and written.
Frequency Access Method Programmable frequency list:
The parameter can be read only. The parameter specifies the number of transmission channels
on which parameter CD is set.
ParamTyp:
Default setting:
Value range:
Example:
WP1UNC.00.01.02 allows two channels for a read attempt.
RP1UNC.00.00 reads out the permitted 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.
