Configuring the RFID Output
In the Reader Configuration screen, you can change the settings for output of the reader, Q value, the
operating frequency and the reader RF test. Select
Cfg on the main RFID demo screen.
Cfg Cfg sets output of a terminal or frequency of Q value. (See Configuring the RFID Output
on page 5-2.)
Ver Displays the firmware version of the UHF RFID reader module.
Clear Selecting Clear, deletes all of the tags displayed
RF Attenuation Adjusts the attenuation of the reader output. 0 equals no attenuation at output. The range
is -30 to +30. The slider moves in 1 unit increments, which are equal to approximately
1dBm. Increasing the attenuation value reduces the output, which decreases the tag
reading performance.
Q Value The Q Value sets the field of detection when multiple tags are read. Setting a Q value of 0
limits the field of detection to tags very close to the reader. Setting a Q value of 9 allows
the terminal to detect tags anywhere within the general vicinity of the terminal.
Custom Frequency
Configuration FHSS : Frequency hopping occurs in intervals defined by the user in the "Step" box. You
can define the range of frequencies in the "Start" and "End" boxes. The frequency
hopping method is pseudo-random hopping.
FIX : The tag is read by continuously using only the frequency designated by the user in
the "Start" box. To set the frequency, highlight the number in the "Start" box by dragging
the stylus over it. Then use the keypad to select a new frequency and click the [Set Freq.]
button.
Listen Before Talk (LBT): LBT motion is executed in intervals designated by the user in the
"Step" box from the frequency designated in the "Start" box to the frequency designated
by the user in the "End" box.
