Vehicle Configuration Settings



Vehicle Configuration Settings

The Vehicle Configuration Settings window provides the commands required for over-the-air programming of the vehicle modem for any or all vehicles in the fleet (if the configuration function selected is supported). The values entered into the configuration settings window only apply to the vehicle currently selected. The following parameters are available within the configuration window.

The ‘Set’ button will send the configuration settings to the currently selected vehicle. The ‘Get’ button will retrieve the currently selected vehicle’s configuration settings.

Note: The values displayed in the configuration settings window usually do not represent what is actually stored in the vehicle. You must press the ‘Get’ button (to request the desired settings), and receive a valid configuration response from the vehicle, to update the configuration settings window.

Speed Limit

The Speed Limit section lets you set the modem’s speed limit configuration. Set up the speed limit parameters if you want the vehicle modem to generate a position report depending on the vehicle’s current speed.

Minimum is the minimum speed limit. A position report will be sent if the vehicle’s speed drops below this value. Enter a value of zero (0) to disable.

Event (min) is the event code (if greater than 0) to be generated if the minimum speed limit is triggered. If an event code is entered, it will be transmitted with the position report (with retries), otherwise just a single position report will be sent from the vehicle. This parameter is not supported by all modems (it is supported by the R210).

Maximum is the maximum speed limit. A position report will be sent if the vehicle’s speed exceeds this value. Enter a value of zero (0) to disable.

Event (max) is the event code (if greater than 0) to be generated if the maximum speed limit is triggered. If an event code is entered, it will be transmitted with the position report (with retries), otherwise just a single position report will be sent from the vehicle. . This parameter is not supported by all modems (it is supported by the FLEETWARE R210).

Time/Distance Reporting

The Time/Distance Reporting section lets you set up the modem’s time and distance reporting configuration. The vehicle modem will send a position report depending on these settings.

No More Often Than is the maximum update rate in seconds. The vehicle will never report more often than this value unless a message is sent from the MDT (if applicable). For the FLEETWARE R210 this value can keep the modem from reporting too often and loading the radio system.

Distance is the minimum distance the vehicle must travel before sending a report. Enter a value of zero (0) to disable.

No Less Often Than is the minimum update rate in seconds. The vehicle will send a position report at least this often, whether the vehicle moves or not. This is also the value you should use for setting up a vehicle’s auto report rate (i. e. TDMA).

Time/Distance History Logging

The Time/Distance History Logging section lets you set up the modem’s history logging configuration. The vehicle modem will store a position report (history point) depending on these settings. The stored history data points can be downloaded at a later time with the ‘Get History’ button in the Communication & Control dialog box. See the Time/Distance Reporting section for more details.

Turn Detector

The Turn Detector section lets you configure the modem to send reports when the vehicle makes a turn. Whenever the vehicle turns through the defined course delta (in degrees) in less than 10 seconds, a position report will be generated.

Course Delta is the change in course (+/- degrees) from the current vehicle’s course (heading) that will cause a vehicle position report. If you enter 40, when the vehicle makes a turn greater than 40 degrees, a position report will be sent from the vehicle. Enter a value of zero (0) to disable.

Event is the event code (if greater than 0) to be generated if you want the turn to trigger an advisory in the RASTRAC viewer. If an event code is entered, it will be transmitted with the position report, otherwise just the position report will be sent from the vehicle.

Geofence (geographic zone)

The Geofence section lets you configure the modem to send reports when the vehicle enters or leaves a geofence (geographic boundary of a map). Whenever the vehicle enters or leaves a defined area (if the hardware supports this function), a position report will be generated.

Advisory Region is the desired geofence you would like to use. All advisories defined in the system will be displayed in the list. An advisory region must be defined prior to enabling this feature in a mobile device. An advisory region must have 3 or more points. The geofence stored in the mobile device will not be exactly the same as the advisory region defined since most hardware devices only store two points for each geofence (usually the upper left corner and lower right corner points (rectangle/square) or a center point and a radius (circle)). The advisory region will be converted to most closely match a region that the mobile device geofence format can recognize (e.g. advisory regions with more than 4 points will be converted to contain 2 points that will contain the region - if 20 points are defined in the region then the maximum upper left latitude and loingitude point will be calculated and the maximum lower left latitude and longitude point will be calculated). The first geofence selection is '*Delete Geofence'. Select this entry to clear (reset) a currently defined geofence in the mobile device.

Zone Number is the number of the geofence zone to be stored in the mobile device (some devices store only 1 zone and some device store up to 10 zones). You can define one zone for the base office (zone 1) and one zone for a possible job site (zone 2). You have to enter the zone number so the device knows which geofence zone to store, update, or reset.

Event Code

The event code section allows you to choose whether events are entered in Hex (hexadecimal) or Decimal. Hex (base 16) is a computer form of decimal (base 10). The decimal number 10 is hex A. The decimal 255 is hex FF.

Note: Some of the values returned from the vehicle (from a get configuration or from a response to a set command) may not be exactly the same as were previously entered. This is because each modem requires a different set of parameters for each configuration setup. For instance, the FLEETWARE R210 uses fractions of degrees instead of meters (or feet) for the distance parameter. It also uses 10s of seconds for the ‘No More Often Than’ parameter. Some AVL modems use kts (knots) for the speed and therefore rounding of mph units may occur. Therefore, some of the values displayed may be rounded or set to the nearest allowed value by the vehicle modem.

Note: Not all AVL modems support vehicle configuration settings. Contact Manning NavComp, Inc. to find out if your AVL modems support over-the-air configuration setup.
