How the T600 Tag Tester works
The T600 tests OBUs by determining the RF signal strength required to successfully and consistently communicate
with a given OBU.
The T600 begins the test by sending out an RF signal at the maximum attenuation level (15 dB). The T600 then waits
for a response from the OBU. If the T600 does not receive a response from the OBU, the T600 decreased the
attenuation by 1 dB (thereby increasing the signal strength) and repeats the process. The T600 continues this process
until a successful read occurs or a response is not received from the OBU at the maximum signal level (0dB).
If the RF signal level required to communicate with an OBU is not within the acceptable limits, the OBU fails the test.
Contact Kapsch TrafficCom Canada Inc. to arrange an RMA so the OBU can be returned.
The
T600 scans the bar code on the OBU to confirm the OBU’s identity.
If the bar code data does not match the data
in the OBU, the OBU fails the test.
The test results
For a tag to pass the test, the following conditions must be met.
•
The Read margin is within tolerance.
•
The Write margin is within tolerance.
•
The Read results are within tolerance.
•
The Write results are within tolerance.
•
The barcode ID must match the transponder serial number.
Margin results
The Margin Read value is the dB level that results in consecutive reads of the OBU, whereas the Margin Write is the dB
level that results in consecutive writes to the OBU. Any Read or Write value outside of the acceptable dB range results
in a tag failure.
Correct tag data
The T600 also checks to confirm that the OBU contains the correct data (correct tag type, correct Agency ID, etc.). If
this information is incorrect, the OBU fails.
