Fast Switching Antenna to Inventory Tags
Under standard operation of tag inventory(Real Time Mode & Buffer Mode), the inventory period will
takes at least 500-800ms. Only when inventory is completed, reader can respond to the other new
command. Sometimes when 500-800ms is not accepted, we need to use Fast Switch Antenna
function.
There are two methods to achieve fast switching antenna.
Method NO.1:
Set the value of Repeat Per Command to 255 (0xFF), as illustrated below:
Click
Inventory
, operating time of each round will be as short as possible; Generally speaking, if
there are only 1 or 2 tags in RF region, it will takes 50ms to finish the inventory before the reader
receive new command. The time-consuming will longer with the increasing tags.
Note: For specific format of command parameter, please defer to the reader's
UHF RFID Reader
Serial Interface Protocol V3.1
.
Method NO.2:
Use
cmd_name_fast_switch_ant_inventory
command (see
UHF RFID Reader
Serial Interface Protocol V3.1
).
Difference between method NO.1 and NO.2 is: the process of sending switch antenna command is
omitted in method 2, so it is faster and more efficient, which takes 25ms to read one tag from one
antenna.
