Troubleshooting
Verify that the RFID Reader is acknowledging the tag by beeping and/or
LED fl ashing blue.
If the reader LED fl ashes blue, verify the reader is outputting serial data
from the reader to Wiegand interface module (WIM). When the reader
fl ashes blue there should be a corresponding red LED fl ash on the
Wiegand interface.
If the reader LED fl ashes blue and the WIM fl ashes red, check to make
sure the top orange LED fl ashes (the initial fl ash should be instant
however repeat fl ashes are controlled by the re-transmission control).
The orange LED indicates when a Wiegand pulse is sent to the access
controller.
If the reader LED fl ashes blue, WIM fl ashes red and top orange LED
fl ashes there may be a wiring issue between the WIM and your access
controller.
The Wiegand interface outputs 26-bit Wiegand data. Make sure that the
access controller you are using is set to receive 26-bit Wiegand inputs.
The factory default is to send a Wiegand output for every tag read made
by the RFID reader. This is adjustable and a delay can be programmed
to minimize the Wiegand outputs sent to the controller.

Resolution
If you do not receive a beep and/or a blue LED fl ash then the reader is not
acknowledging the RFID tag.
If there is not a fl ash of the red LED when a tag is read then there is a
problem with the serial data feed between the reader and WIM. Double
check the wiring between the two devices to make sure all of the
connections are correct. You may confi rm data output by connecting
a computer with serial connection and use a telnet program (such
as putty). The settings for the connection should be 9600,8,N,1. You
should see raw tag data if you connect to the reader using the following
connection (Green - RXD, White - TXD, Yellow - Com). If there is no
serial data coming from the reader then the reader has malfunctioned
and needs repair. If there is serial data coming from the reader then the
problem is in the WIM and it needs to be replaced.
If no orange LED fl ash is observed then there is a problem with the WIM
and it should be replaced.
Make sure your wiring run is less than the maximum distance of 98.5 ft
(107 m).
With a DMM, measure for DC voltage between the Data 1 and COM as
well as Data 0 and COM. You should read a normal operating voltage of
at least 4.9-5V DC. A reading of less than this voltage indicates a voltage
drop potentially due to cable distance or poor connections.
Disconnect the Wiegand connector from the WIM module (Access
Controller still connected) and measure the voltage at the connector. This
will test the wiring run from your access controller to WIM and should be
>4.9V DC. If you measure 0V DC then there is a break in your wiring run.
Disconnect the Wiegand connection from the Access Controller (WIM
still connected) and measure the voltage at the connector. This will test
the wiring run from your WIM to Access Controller and should be >4.9V
DC. If you measure 0V DC then there is a break in your wiring run.
Try swapping the Data 0 and Data 1 wires at either the Wiegand interface
or access controller and retest.
Change the Wiegand re-transmission delay setting (0-15 seconds) using
the steps in the installation manual.
