8.7 Same tag read rate
The read rate of the same tag must be manipulated through the following commands:
● Gen2session
● gen2target
● rfon
● rfoff
The commands mentioned above change the parameters of the UHF EPC Gen2 protocol and have an
effect on communication between the tag and reader.
Combinations of values for the Session and Target of the tag reflect how often a tag that has already
responded to an inventory will respond again, in other words, how fast a tag is reassing.
Examples:
A. I would only read only once the EPC id of a tag and that same EPC id does not repeat itself
while the tag is in the reading field of the reader. Configure as follows: gen2session
s2<CR>
gen2target a<CR>
B. I would like to read the same tag again and again while it is in the reader reading field. Set up
as follows:
gen2session
s0<CR> gen2target
ab<CR>
In this case, what will determine the read repetition rate are the rfon and rfoff commands, i.e.
the sum of the times will dictate the repetition rate. The highest possible read repetition rate is
every 50ms:
rfon 50<CR>
rfoff 0<CR>
ALERT
:
The tag read rate can be much faster than the rate of sending the
results by keyboard emulation (hid), that is, if the chosen read rate is
high and the chosen interface is keyboard emulation, the reader will
store the reading result and will be sending it even after the tag is
removed from the reading field.
