5.0 Troubleshooting the Reader Installation
Problem Probable Cause Corrective Action
The reader does
not recognize a
card/tag (no
beep, no LED
flash). 1. One or more of the
reader's wiring
connections are
incorrect.
• Power down the controller and verify the
wiring connections are correct for the
reader/controller combination per the
instructions provided in the Connections
section on pages 2 and 3.
2. The reader is not
receiving proper power
from the controller.
• Verify the voltage supplied to the reader is
between 5 and 14 VDC.
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
1
are installed across both jumper pins.
If the controllers are using Doors TM
software, verify JP
1
on the controller and
the Receiver card1 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).
1. The receiver board's jumper is on the underside of the board. Gently pull the receiver board away from
the controller, verify the jumper setting is correct per your application, carefully align the connectors on
the receiver board with the pins on the controller, and gently push the receiver board back into place.
