Value range:
Example:
WP1UQW.00.01.04 sets the Q value to 4. The read/write head therefore works with 2
time slots.
RP1UQW.00.00 outputs the set Q value.

st
1 Byte = 80
■
You can not change the country identifier
The country identifier can be write-protected by the manufacturer. This is the first byte set to 80.

Note!
Once you have set the country identifier, the read/write head automatically resets all other
parameters to their respective default values. When programming or configuring parameters
manually, always set the correct country identifier before changing any other parameters.
Note!
The country identifier remains unchanged when the default status is restored.
Note!
The IUH-F190-V1-FR2-02 is supplied ex-works with the country identifier "02" for the USA,
Canada, and Mexico. Due to legal regulations, you cannot change this country identifier in the
IUH-F190-V1-FR2-02.
Example:
WP1URC.00.02.00.03 sets the country identifier to China.
RP1URC.00.00 reads out the country identifier set.
The serial response .30.31.00.01 indicates the country identifier for Europe, which you can
