How do I know what installation to use?
If your vehicle was manufactured in 1996 or after it will have an OBDII port. If this is the case then you can most likely use the OBD DriveRight installation. In this installation the OBD harness cable will just plug into this OBDII port. There are a few cases where this port will be present but will not be compatible with the OBD install kit. Please contact Davis Technical support to make sure your vehicle is compatible. If your vehicle is not compatible with the OBD installation then the VSS installation will be the next choice. In this installation you use the VSS wire as the input signal. You can find where the VSS wire is on your vehicle at the www.rostra.com website. If your vehicle does not have the VSS wire then you will need to go with the General Duty or Heavy Duty installation. These installations use a magnet that is attached to your drive shaft that passes by a speed sensor that is mounted to vehicle. The heavy Duty is used in larger vehicles or in vehicles that will be used in rugged terrain.

What is the calibration number when using the OBDII installation?
If you are using the DriveRight software set the VSS Pulse to VSS Other and 75000. This sets the Pulse per reading to 32 and then automatically sets the calibration number to 21475 for DR 500’s and 37748 for DR 600’s. If you are setting it manually the procedure is the same per the DriveRight User Guide starting on page 6.

I downloaded my DriveRight last week and again this week yet my download score in the Driver Safety Score Report is 0 and the max download days shows 100 although the Days since last download report shows 7 days. What's happening?
The Download Score in the Driver Safety Score can sometimes be a bit confusing. The days since last download report is just that, the number of days since you last downloaded which in this case is 7 days. However in the Driver Safety Score report the column that is labeled Max Download Days is 100 because that is the largest number of days between downloads for the time span of the report. Therefore your download score will be 0.

When using the OBD Installation the vehicle speed is off and when I look at the calibration number the number changed by itself. What happened?
The vehicle speed being off is probably caused by the change in calibration number. The calibration number changing by itself is a bug in VMS version 2.6.1. This bug was fixed in version 2.6.2

After installing the FMS software it does not see my desktop reader. How do I fix this?
The ACS setup installs 2 sets of drivers for Windows, namely PC/SC and proprietary USB drivers. By default the operating system allows the reader to run on PC/SC driver if it’s present in the system. However, in order to with the ACS reader, we have to manually change the driver from PC/SC mode to proprietary mode. To do this use the instructions that came with the Desktop reader or contact Davis Technical support for the instructions.

Can you assign multiple vehicles to one driver with the SmartCard?
Yes, you can authorize up to five vehicles for a driver with the SmartCard. From the FMS software go to SmartCard/Setup Card. Select the driver. In the Vehicle (in the database) window all the vehicles in the database are listed. Highlight the vehicle you want to authorize for that driver and select the right arrow so that vehicle moves over to the Authorized Vehicle window. If you want to authorize another vehicle repeat this procedure. Select the Set button and this will authorize those vehicles for that particular driver.

I connected the Starter Interrupter as per the instructions in the manual but when I insert an unauthorized SmartCard in the On-Board reader the vehicle still starts. Why is this?
The diagram in the manual for the DriveRight SmartCard system on page 12 does not work on every vehicle. Use the Addendum to the 8116 Starter Interrupter kit. That addendum has a wiring diagram that will work on more vehicles and is actually easier. If you need this addendum contact Davis Technical support.

Why is my speed reading very high or erratic?
Your DriveRight may not be calibrated properly. Refer to your user's guide for the proper calibration procedure. Calibrating at 25 miles per hour will bring the acceleration, velocity and distance readings to a reasonable value. Calibrating the DriveRight to a distance over 20 miles (32 kilometers) will yield very accurate acceleration, velocity and distance readings.

Why do I lose the time and date when I re-power?
If your DriveRight is locked up and you remove power to restart it you will lose the time and date. If you are a driver and in a remote location and you do not have a settings code you will not be able to reset the time and date. The better way to restart/reset the DriveRight is to reboot using "+" and "mode" keys. This reboot does not affect the date or date.

I cannot download my DriveRight 600e via remote modem but the DriveRight 500 worked fine. Why is this?
The DriveRight 600e and 500 communicate at different baud rates. In the field/remote modem you will need to program in the following commands AT&N0 or AT &N10 through HyperTerminal or similar communication programs. If a DriveRight 500 is used then the field/remote modem needs to be programmed with AT&N3.
