8.0 Troubleshooting Read Range Issues
This section will help you troubleshoot read range issues with the V-track system. You will need an LRT-5 Transponder to
perform these steps. In order to resolve these issues it helps to understand the basic operation of the V-Track system. It
consists of three parts:
• Antenna/Exciter
• Receiver
• Vehicle Tag
The antenna/exciter operates as a remote “switch” that activates the tag. Whenever the tag is in the field, it will transmit
data. This is easily proven with the use of the provided test tag. For this portion of testing, no receiver is required.
When the tag is activated it will transmit the encoded ID number via an RF signal to the receiver.
The receiver can be located up to 100 ft from the vehicle being detected. When a signal with correct data is received, the
receiver processes this and ships it to the host controller through the connecting data cable.
