Correct Reader Grounding
Ground the reader following the recommended grounding shown here.
Do not ground the input power supply.
5. Apply power and verify reader sign-on message appears on
laptop/computer display as described in Pre-Installation
Testing Step 3 on page 6.
6. Use reader commands to query status and set up the
system to ensure the following:
•
If multiple readers are used, ensure that the frequency separation
between readers is sufficient and make sure that each reader is set up to
the proper settings
•
Adjust reader angle/power to optimize read zone for each reader.
•
Check for interference by each reader (or by the environment).
7. If using Wiegand tags configure the reader for Wiegand
operation and connect the Wiegand interface. See Step 5 on
page 7.
8. Disconnect the laptop and connect reader to back end
devices and recheck read zone and for interference between
readers.
9. System-test the reader.
Once all in lane testing is complete, perform a system test using tagged
vehicles passing through numerous lanes. The tag reads are sent to the back
end system and evaluated for validity.
