Filling DFS and location library, establishing connections and checking status
How to "create" DFS and location in the library and establish connections in DFS-CAS software to communicate with your Driver Feedback Sign DFS 700 unit and check its status.
More details :
For each DFS unit, a DFS item has to be created in the "DFS list" of DFS-CAS software. As many locations as required can be created in "Location list" in order to manage speed data for each of those locations. A communication via Bluetooth is demonstrated. The COM port used here as an example in this video will depend on the COM port indicated by your Bluetooth driver. Then you will be shown how to check the status of the DFS 700 unit. The error code on the GSM communication indicates that there is no GSM modem connected to the unit
Setting DFS 700 parameters in the software 3M DFS-CAS
How to set the parameters of your Driver Feedback Sign with the DFS-CAS software: speed display, log levels and scheduling.
More details :
Once the communication is established with the DFS unit, the parameters can be read from the DFS unit. The speed registration and the speed display are set separately in the configuration menu. The upper speed limit display - above which no more speed is displayed in order to avoid speed challenges - is set as "Red display ... to ...".
Extracting data from the DFS unit to the DFS-CAS software
How to download speed data from your Driver Feedback Sign unit and assign the data to a location in DFS-CAS software.
More details :
Once the communication is established with the DFS unit, data can be downloaded onto your hard drive. The fastest method is with the USB cable (the download has been shorten in the video). Then data have to be assigned to a location chosen in the "Location list". The user has to determine manually the time period which corresponds to the location. Speed measurements can be viewed day by day. Statistics are presented in the tutorial below.
Creating and saving graphs
How to exploit downloaded data in DFS-CAS software.
More details :
With data assigned to a location, it is easy to create statistical reports and graphs with the "Create report" command. Data timeframe has to be selected and filters can be set to fine tune the reports. Statistical information is displayed at the bottom of the table. 8 reports are available and integrated into the DFS-CAS software. They can be customised and saved to your computer in several formats.
