Problem Probable Cause Corrective Action
The reader does
not recognize a
card/tag.
1. One or more of the
reader's wiring
connections are incorrect.
• Power down the controller and verify the wiring
connections are correct.
2. The reader is not
receiving proper power
from the controller.
• Verify the voltage supplied to the reader is correct per
the Operating Voltage section on page 1.
3. The reader is mounted
too close to a device that
radiates electromagnetic
interference.
• Devices such as computer monitors radiate
electromagnetic interference that affects read range.
When possible, relocate either the reader or the device
to provide a greater distance between the two.
4. A jumper is not set
correctly on the
controller.
• For a PXL-250: Verify there is a jumper across pins 1
and 2 of JP4 (refer to the Technical Reference manual
for more information - Keri P/N 01836-001).
• For a PXL-100: If the controllers are using TAP TM
software, verify JP1 on the controller and the jumper
on the Receiver card are installed across both jumper
pins. If the controllers are using Doors TM software,
verify JP1 on the controller and the Receiver card are
not installed across both pins (typically the jumper
will be installed onto one of the pins to keep it
available).
• For an IntelliProx: Verify there is not a jumper across
pins 1 and 2 of JP1 (typically the jumper can be
installed onto one of the pins to keep it available).
5. You are using an
incorrect type of card.
• Make sure you are using an access card that is
compatible with the reader.
6. The reader is unable to
read the card.
• Verify there is nothing that can interfere between the
reader and the access card.
The reader has a
short read range.
1. The reader's controller is
not properly grounded.
• Ensure there is a quality earth ground connection
made to the controller. Refer to the controller's
documentation for specific information regarding the
earth ground connection.
2. The shield wire for the
reader's cable has opened
somewhere between the
reader and the controller.
• Verify the shield line from the controller to the reader
is one continuous, connected line. Refer to the
controller's installation documentation and verify the
shield line is correctly connected to the controller.
3. The reader is mounted
too close to a metallic
object (only MS-5000,
MS-7000, or MS-9000).
• Remove the reader from its mounting surface and
ensure there is no metal on the mounting surface
within 1 inch of the reader.
4. The reader is mounted
too close to a device that
radiates electromagnetic
interference.
• Devices such as computer monitors radiate
electromagnetic interference that affects read range.
When possible, relocate either the reader or the device
to provide a greater distance between the two.
5. The controller is mounted
too close to a device that
radiates electromagnetic
interference.
• Devices such as computer monitors radiate
electromagnetic interference that affects read range.
When possible, relocate either the controller or the
device to provide a greater distance between the two.
6. The reader is powered by
a switching power
supply.
• Switching power supplies are EMI sources. Change to
a linear, regulated power supply.
