Common Problems with NT132
Components
Cable
Problem: The NT132 System has reduced range
Most of the problems encountered with the NT132 system lie with the
cables. This includes having little or no range on the antennas.
Check these items first:
Step 1:
Ensure that RG-58/U with 100% foil shield coverage is
used.
Step 2:
Ensure that the cable lengths are within specifications: no
more than 80 feet between the Reader and the ATU and
no more than 20 feet between the ATU and the antennas.
Step 3:
Ensure that the connectors are well fastened and in good
order.
Step 4:
Ensure that TX is connected to TX and RX is connected to
RX on the Reader, ATU and antennas.
Step 5:
Check the continuity of the cables. See page 87 for details
on checking continuity.
Power
Problem: The NT132 System has no range
Step 1:
Check that all LEDs in the Reader are on. LEDs indicate
that the Reader is receiving power.
Step 2:
Check that the Reader has power. Information on
providing power can be found on page 32.
Step 3:
Use the multimeter to check voltage into the white terminal
block.
ATU
Problem: The ATU meter does not show any voltage
Step 1:
Tune the ATU. See page 73 for information.
Step 2:
Check if the LEDs in the Reader are on. If not, ensure that
the Reader has been connected to power. Information on
providing power can be found on page 32.
