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 4.2.3.
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 54 and see
"Output Additional Information, "Information" IF" on page 51.
ParamTyp:
Example:
RP1UMD.00.01.01 returns the response .30.01.13.04.00.32
Explanation of the response:
<Status> = 0
<ChanNo> = 1
<RSSI> =. 13 = 19
<TXChannel> =. 04
<TXPower> = .00.32 = 50
Measurement of Reflected Transmitting Power "Measure Reflection" MF
This parameter measures the reflected transmitting power of the antenna and the environment.
The results are output as one byte per transmission channel. The transmission channels
depend on the country identifier set (parameter RC), see chapter 4.3.
To obtain the reflected power in dBm, subtract the value 100 from the return value in decimal
notation.
ParamTyp:
Value range:
1.0 or 255 is returned for values outside the value range
