Tuning the Lane
This chapter provides instructions for tuning the lane for optimum
performance and for verifying that the installed IT2200 Reader System is
functioning correctly.
Why You Need to Tune a Lane
You tune a lane to:
• Test the installed reader system
• Adjust the read/write zone footprint to guarantee reliable tag performance and
proper transaction framing
• Minimize the RF power output to decrease interference with adjacent lanes
The read/write zone is adjusted by changing the antenna position, antenna mounting
angle, and uplink and downlink RF power. The nominal antenna angle is 15° up from
horizontal in a dedicated lane and 10° up in a mixed-use lane.
Note: TransCore recommends that two people accomplish this procedure.
Warning
Switch off RF power before working on antennas.
The following procedure assumes that the equipment to be tested and commissioned
has been properly installed and that host computer power is available.
This lane tuning procedure tests the following equipment:
• IT2611 RF Module
• AA3152 or AA3153 antennas
• IT2502 Check Tag Antenna
• IT2020 Reader Logic Card
• Reader-to-RF module tag data/control cable (data cable)
• RF module power supply
• RF module power supply cable
