Configuration is only necessary if there are multiple VPRS within 100 m of each other in order to prevent interference between them. The VPRS Configuration Software can be used to configure both the Beacon and Rover units. Ensure that power is supplied to the units and connect them to the PC as per the Hardware Installation.
To connect to a Beacon or Rover, a COM port will first need to be selected from the drop down list of available COM Ports. If the required COM port is not displayed, pressing the Refresh button will refresh the COM port list.
Once you have configured the Beacon/Rover, press the Upload button to upload the configuration to the Beacon/Rover.
Pressing the Save button will save a .JSON configuration file locally to your computer, enabling you reuse the configuration at a later date.
Once connected to the Beacon/Rover, the 'Files' menu allows you to create a new configuration, save a .JSON configuration file locally to your computer or open a previously saved .JSON configuration file.
The Beacon ID and Channel Frequency are configurable in the beacon unit. By default, the Beacon ID will be 1 and the Channel Frequency will be 3993.6 MHz. The Beacon ID will need to be unique if there is more than 1 system within a 100 m range of each other.
There are more settings that can be configured in the Rover unit as this connects to the VB3i or 3rd Party Data logger. The Beacon ID and Channel Frequency are configurable and must match the beacon unit. By default the Beacon ID to range to will be 1 and the Channel Frequency will be 3993.6 MHz.
When connected to a VPRS Rover unit, there is an option to set the Total number of systems. The maximum number of systems available are 5. The default will be 1. This means it is possible to use 5 VPRS systems in the same vicinity at the same time. So if there is more than 1 system being used, then this parameter will need to be modified as well as the System number, which is the system that the VPRS Rover unit is connected to. This is 1 by default.
The Beacon ID to range to parameter will need to match the Beacon Unit ID that you will be pairing with. The Output rate will change depending on the Total number of systems. For 1 – 2 systems, the output rate can be 100 Hz, 50 Hz or 25 Hz. For 3 – 4 systems, the output rate can be 50 Hz or 25 Hz. With 5 systems, the output rate will be 25 Hz.
It is possible to change the radio frequency between 3993.6 MHz or 6489.6 MHz. Advanced radio settings are also available, including Tx power level, Leading edge time threshold and Preamble number, however these should only be changed under the guidance of Racelogic Support.
There are different modes available for the CAN output and the details can be seen in the drop-down menu. Other parameters that are configurable include the CAN ID, CAN Baud Rate and enabling CAN termination in the VPRS.
There are different modes available for the Serial output and the details can be seen in the drop-down menu.
Viewing Live Output
When connected to the Rover Unit, if the Cable icon is selected, a live numerical range value (to 2 decimal places) to the Beacon is displayed along with a live graph. This has a refresh rate of 10 Hz and is useful for a quick functional test of the VPRS, or a demo without a VB3i.
Note: The Beacon must be powered to see a live range output.
