Setting Up the Exciter’s Test-Tag
5-12 Configuration and Operation
In installations where random interference is observed please contact Lyngsoe Systems A/S for
assistance.
IMPORTANT * For a normal setup, the sum of (HNL+RSS) must be less than - 85 dBm.
* If the noise level is higher than -95 dBm, disconnect the UHF antennas from the Reader, and
check whether the
HNL value drops below -107 dBm. If this occurs, it means that there is
unwanted transmission on the UHF channel. To correct this situation, refer to Chapter 4, Setup
Guidelines in the RFID System S21 Technical Guide.
7. Place your Test Transponder PT21 1-2 m away from an Exciter that is controlled by the Reader
you are configuring. For more information about identification zones and the Test
Transponders, refer to Chapter 4, Setup Guidelines in the RFID System S21 Technical Guide.
8. Start the excitation field, by typing:
B<Enter>
9. Verify that the DATA LED is flickering, and check whether the Test Transponder’s messages
are displayed on the PC’s screen.
If data is not displayed, check the Reader’s parameter configuration, and follow the
troubleshooting instructions in Chapter 7, Troubleshooting.
If the number of displayed messages is below n=IP+RC-2, check the carrier threshold and try
to adjust it again (go to Step 1).
10. Remove the Test Transponder from the field and make sure that it is no longer transmitting by
ensuring that the DATA LED is not flickering.
11. Set the DAR and DHX parameters to their original values. To store the settings, type
:CONFIG:STORE<Enter>
