IUH-F190-V1-*, IUT-F190-R4-V1*
Operation
Output Additional Information, "Information" IF
Parameter IF allows you to output additional information providing that the reading was suc-
cessful and the multiframe protocol is activated. See "Protocol Mode QV" on page 55. The
additional information is the RSSI value of the reading, the transmission channel used, and
transmitting power of this reading.
ParamTyp:
Default:
Value range:
Example:
WP1UIF.00.01.01 prompts the read/write head to output additional information after each suc-
cessful reading.
RP1UIF.00.00 outputs the value of parameter IF.
The additional information is output in the following format:
B<ChanNo> <InfoTyp> <RSSI> <TxChannel> <TxPower>
To distinguish the additional information from the standard outputs, the output begins with the
status B as the first ASCII character, followed by the IDENTControl channel. This is followed by
the <InfoTyp>, which indicates that this is a type .01 information frame. The output ends with
the RSSI value (1 byte), the transmission channel used (1 byte), and the power used (2 bytes).
The RSSI value is between 0 (= low) and 100 (= high).

Memory Module for Tag Accesses to the "Memory Bank" MB
This parameter specifies the bank accessed by the read/write commands SR, ER, SW, and
EW. See chapter 3.2.3.
ParamTyp:
Default:
Value range:
Example:
WP1UMB.00.01.03 sets the bank to User Memory
Retrieve Additional Information MD
This parameter allows you to retrieve information about the last successful tag access. This
returns the RSSI value with a length of 1 byte, the transmission channel used with a length of 1
byte, and the transmitting power with a length of 2 bytes. The RSSI value may be between 0 (=
low) and 100 (= high).
Parameter MD allows the same data to be accessed in the single-frame protocol as is available
in the multiframe protocol with parameter IF. See "Protocol Mode QV" on page 55 and see
"Output Additional Information, "Information" IF" on page 52.
