Reader Set Up

1. Use reader commands to query status and set up the reader.

2. Make sure that each reader is set up to the appropriate settings.

3. Adjust reader angle and power to optimize read zone for each reader.

4. Check for interference from each reader or the environment, using a portable ﬁeld spectrum analyzer

if one is available.

Note: If using Wiegand tags, conﬁgure the reader for Wiegand operation and connect the

Wiegand interface. Refer to “Conﬁgure for Wiegand Operation” on page 11.

5. Disconnect the computer and connect the reader to back end devices. Recheck read zone and for

interference between readers.

6. System-test the reader to verify that the gate opens when a valid tag is read.

7. 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 gate controller back end system for validation.
