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

 

 

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.

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

FHSS : Frequency hopping occurs in intervals defined by the user in the "Step" box. You

Configuration

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.
