Command MF - Mode 2
In total, there are 15 tags in the measurement range of the read/write head, with three groups of
five marked as either A, B, or C. The filter is set to "B" by command FI.
If you execute command MF12 (Activate Filter - Mode 2), this command affects all subsequent
commands.
If a write command is executed next, all tags in the measurement range that are not "B" tags are
selected. These tags are assigned a 'Selected' flag. The write command is executed only for
tags with no Selected flag.
When the filter is set to "B," command MF12 (Filter Activated - Mode 2) selects all "A" and "C"
tags, and the following commands address the unselected "B" tags.

Difference Between Command MF - Mode 1 and Command MF - Mode 2
In both cases, the subsequent commands are applied only to the "B" tags in the measurement
range.
With MF11, "B" tags are assigned a Selected flag. With MF12, "B" tags are not assigned a
Selected flag.
If a "D" tag with a Selected flag from the operation of a different read/write head enters the mea-
surement range, this "D" tag will execute the subsequent commands if MF11 is activated. If
MF12 is activated, this "D" tag will not execute the subsequent commands.
