IT2235 Dynamic Performance Drive-Through Tag
Test
1. Mount an IT2235 Tag on the inside of the vehicle’s windshield. The tag must be
at least 5 cm (2 in) from the windshield frame or rear view mirror post, and it
must be below the tint line at the top of the windshield. Drive the vehicle through
the center of the lane at 48 km/h (30 mph).
2. Toggle Run/Pause on the host computer to clear the counter.
3. If a message appears signifying a buffer overflow, the total number of
handshakes is too high for the host to process. To continue this test, drive
faster through the lane to reduce the handshake count.
4. Drive the vehicle through the lane three times. The handshake count should be
between 65 and 100 for each run.
IT2221 Dynamic Performance Drive-Through Tag
Test
1. Replace the IT2235 Tag with an IT2221 Tag and repeat Step 3 of “Starting the
Dynamic Performance Test” on page 5-15.
Note: Remove the IT2235 Tag from the vehicle or place it in a sealed protective
electrostatic device bag.
2. Drive the vehicle through the lane three times at 48 km/h (30 mph). The
handshake count should be between 65 and 100 for each run.
3. Close the host software.
4. Connect the data cable to the reader logic card in the host computer. Tighten the
connector and ensure that the cable’s ground wire is securely grounded to the
host computer enclosure.
5. Switch on the host computer. It should initiate automatically. In 30 to 45 seconds,
the three LEDs (Transmit Active, Uplink Source On, and Downlink Source On)
farthest from the bracket on the reader logic card should light (see Figure 5-7). If
the Self-test Fail LED lights, go to Chapter Chapter 6, “Troubleshooting the
Installation.”
