7 Troubleshooting
This unit, if not installed in strict compliance with AWID’s installation instructions, may
not function to specifications. Use the checklist below to identify the problem:
•
Is the card valid and working?
- Try some different cards!
•
Is the reader wired correctly?
- RED-BLK :5-12V, reader should work
•
Is the unit grounded properly?
- DRAIN-EARTH: less than 50 Ohms
•
Is the card presented correctly? - Card face parallel to reader face
•
Is a power supply correct?
- No switching power supply please!
•
Is reader voltage/current correct? - 5-12V @ 150mA typical
•
Is the environment free from electromagnetic interference? - Run cable away
from other data carrying cables, reader away from electromagnetic interference
sources!
When troubleshooting, try to identify the source of the problem to a unit level. “Is the
problem originating from the panel?” Or “is the problem originating from the Reader? “
Maybe the problem “is the power supply?”
All AWID’s readers will need only a power supply and a valid card to work properly. If
the reader is only connected with RED (+5-12V) and BLACK (Ground), and presented
with a valid card, the reader will BEEP and momentarily turned AMBER. If the Card
stays within the reader zone of surveillance, the LED on the reader will become flashing
RED and GREEN. When the card is removed, the LED will return to RED, signifying it
has returned to stand-by mode. When the reader works according to the tests above,
the reader is working properly.
Do not cycle the power supply ON and OFF in rapid succession. Each power has its
unique “decay” characteristics, turning the power supply ON and OFF in rapid
succession can cause the Microcontroller to lock-up, due to improper initialization.
Always turn the power supply OFF and count 10 seconds before turning ON again.
To check the validity of the output data in the absence of a panel, you will need to build
a patch cable between the reader and a PC. Call AWID’s Technical Support for details.
If problem persists, consult the system manufacturer. If problem is the reader, consult
AWID’s Technical Assistance Department.
