Setting Up the Carrier Threshold

Configuration and Operation 5-11

5. Set the carrier threshold, by typing:

S <Enter>

:CONFIG:THRESHOLD<Enter>

Note If the Reader resets itself, repeat the procedure from Step 1.

6. Monitor the DATA LED for at least 10 seconds. The LED must not flicker. If it does flicker

occasionally, increment the

RSS parameter value by one. Go to Step

In installations where random interference is observed please contact Lyngso Industri 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/PT23 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 follows the

troubleshooting instructions in

Chapter 7, Troubleshooting.

If the number of displayed messages is below n=IP-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.
