Check the Antennas and Cables for Continuity
Continuity is a direct connection or dead short between two points on
a cable. Continuity can expose bad cables or problems with
connections.
Step 1:
Turn off the power to the Reader.
Step 2:
Disconnect all the cables between the Reader, the ATU
and the antennas.
Step 3:
Check each cable for continuity. If continuity is present in a
cable, then the cable is shorted. Redo the cable.
Reception
The reception portion of the system should not exhibit continuity. If
continuity is found during any of the following steps, fill out the
Customer Support Questionnaire (page 107) and call Customer
Support at 1-800-577-6080.
Step 4:
Check the
RX
connector on the Reader for continuity. If
there is continuity, then there is a problem with the
Reader.
Step 5:
Connect the coax cable from the
RX
connector on the
Reader to the
RX
Reader
connector on the ATU and
check for continuity in the
RX Antenna
connector. If there
is continuity, then there is a problem with the ATU.
Step 6:
Check the
RX
connector on the antenna for continuity. If
continuity exists, then there is a problem with the antenna.
Step 7:
Connect the coax cable from the receiving antenna to the
RX Antenna
connector on the ATU. If there is continuity,
then there is a problem with the ATU.
Transmission
The transmission portion of the system should have continuity. If
continuity is not present, then follow the directions given for each
step.
Step 8:
Check the
TX
connector on the Reader for continuity. If
continuity
does
not
exist, there is a problem with the
Reader. Fill out the Customer Support Questionnaire
(page 107) and call Customer Support at 1-800-577-6080.
Step 9:
Connect the coax cable to the
TX
connector on the
Reader and check for continuity at the other end. If there is
no continuity, the cable is bad. Redo the cable.
Step 10:
Connect the other end of the coax cable to the
TX Reader
connector on the ATU and check for continuity in the
TX
Antenna
connector. If continuity does not exist, then there
is a problem with the ATU. Fill out the Customer Support
