After the power-on
test is finished, the
sign-on message is
displayed on the
PC, and the DATA
LED is flashing
only
when a
Transponder is
activated.
After the power-on
test is finished, the
sign-on message is
displayed on the
PC, but the DATA
LED is not flashing
when a
Transponder is
activated.
The configurations of the
Transponder and the
Reader do not match.
The carrier threshold
value is too high.
1. Using a Test Transponder TST95
that has been programmed for your
application, test the Reader’s
receiving capability.
2. If you can receive transmitted
messages from the TST95, the
Transponders are either not
correctly configured for your
application, or they are out of
specifications. Reprogram the
Transponders and check whether
the Reader can receive messages.
3. If you cannot receive transmitted
messages from the TST95, the
Reader has an incorrect
configuration. Go to Steps 4 and 5.
4. Check whether the DAR parameter
and the Group R parameters are set
according to the application’s
specifications.
5. With this new set of parameters,
check whether the Reader can
receive transmitted messages from
the TST95. If the Reader can receive
the messages, save its configuration,
by typing the following commands
and pressing <Enter> after each
command: :CONFIG:STORE,
:RESET.
1. Run the procedure, 95 Series RFID
System - Final Test on page 5-14.
Step 2 - Set up the Carrier Threshold
for the Reader.
2. If the Reader reports a channel noise
level below -95dBm, but you are still
not receiving the Transponders’
messages, check the noise level
reported by the Reader with and
without connected UHF antennas. If
the noise level is identical or varies
slightly (±1 dBm), replace the
Reader.
3. Check the HNL and RSS parameter
values.
