Troubleshooting the Installation
This chapter provides information on cross-lane interference and
troubleshooting instructions for use when installing and testing the
IT2200 Reader System with Multimode Capability.
Required Equipment
You need the following equipment to complete the tuning procedure:
•
Hydraulic lift
•
Test computer (PC or lunch box type) with the IT2200 Engineering Host #11254-
00 software, Version 1.03 installed and an available ISA slot for installing a
reader logic card
•
Data cable to use as an extension cable to the installed data cable. Use a 2m (6-ft)
DB-25, fully wired, plug and socket end cable.
•
One pair of walkie talkie radios, preferably UHF band
•
Multimeter, Fluke 87 or equivalent
•
Vehicle. Use a car or truck for interior tags or a truck for exterior tags.
•
Commercial grade heat gun
Cross-Lane Interference in RFID Systems
As discussed in “Noise and Interference Immunity” on page 2-10, RFID systems are
subject to various types of interference that can affect the level of communications
between a tag and reader system. Another type of interference that can result from the
operation of the reader system is called cross-lane interference.
What Is Cross-Lane Interference?
Cross-lane interference occurs when the RF generated in one toll lane interrupts the
RFID operation in another lane thereby causing the affected lane to perform poorly.
Before diagnosing cross-lane interference, it is necessary to understand what consti-
tutes a satisfactorily performing lane.
