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 JP1 on the controller and the Receiver
card
1
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.
