/reader/gen2/BLF
Type: Integer
Default value: 250
Writable: yes
Products: M6e, M6
Sets the Gen2 backscatter link frequency, in KHz. See the M6e Hardware Guide for full
configuration options and supported BLF values.
See
for details.
Note
It is important that the
, in
equivalent frequency units. If its not then the reader could be reading data
faster than the transport can handle and send and the reader’s buffer might
fill up.
/reader/gen2/q
Type: Gen2.Q
Default value: Gen2.DynamicQ
Writable: yes
Products: all
Controls whether the reader uses a dynamic, reader controlled, Q algorithm or uses a
static, user defined value, and that static value. The value of Q only makes a difference if
it is considerably too high or considerably too low. If it is considerably too low, all slots will
contain collisions and no tags will be read. If it is considerably too high, then many slots
will pass with no tag attempting to communicate in that slot. The number of slots is 2^Q,
so for 7 tags, a Q of 4 should be ideal. Each slot takes approximately 1 microsecond, so
the overall affect of empty slots is not significant to the overall performance unless the Q
is extremely high.
The Q value will not affect the write success rate.
