The VDO RoadLog ELD is still the only ELD that features an integrated log printer. With the integrated printer, there’s no need to worry about transferring electronic logs during an inspection stop.

The VDO RoadLog printer helps provide a faster roadside inspection and the best solution when a visual inspection is required.

The printer uses fade-resistant thermal printing paper to ensure a clear and easy to read result. 

How do I transfer the data from the VDO RoadLog ELD in my vehicle to my home office?

VDO RoadLog ELD users transfer data using their VDO RoadLog Driver Key. The Driver Key is a USB drive that can be used to upload the data to VDO RoadLog Office using any computer with internet access.

VDO RoadLog ELD Plus users get automatic data transfer via cellular connection.

How much data is saved on the VDO RoadLog hardware?

The VDO RoadLog will retain the drivers prior 24 days on the device at all times. For a roadside inspection, the VDO RoadLog will only print the required last 7/8 days.

Does the VDO RoadLog tell me how much available drive time I have left for my day?

Yes, the VDO RoadLog ELD shows you the exact amount of driving time available before you have to take your break. The VDO RoadLog ELD also shows your weekly availability.

Will the VDO RoadLog alert me when I am running out of time?

Yes, VDO RoadLog ELD will alert you when you’re approaching the end of available time. When you start your day, a green bar will appear across the screen with 8:00 inside. This green bar indicates the amount of drive time available prior to requiring a :30 minute break. With 3:00 remaining, the bar will turn yellow and with 1:00 remaining the bar will turn red. After you take your required break, you’ll see your remaining availability for the day.

How do you I install my VDO RoadLog ELD?

The VDO RoadLog was designed for a fast and easy installation. Select where you want to mount it on the dash. It should provide good visibility for you and a clear view to the sky. Peel the backing off the adhesive strip, and place one side of the adhesive onto the bottom side of the bracket and the opposite side onto your selected area on the dash. Plug your cable into the vehicle’s data port and run the cable around the dash to where the bracket is placed (you can usually tuck the cable into the space where the dash meets the windshield). Plug the cable into the bottom of the VDO RoadLog ELD and secure the ELD into the bracket. Done!

What is a VDO RoadLog Y cable?

The Y cable has two plugs at one end to provide a cleaner installation appearance and allow other tools to be plugged in without having to unplug the device. A Y cable option is available for all of our cables.

How do I know which installation kit (cable) to choose for my vehicle?

You will want to purchase a cable with the pin connection that matches the connection available on the vehicle’s data port. It is always a good practice to check each vehicle to confirm the pin connection but as a Rule:

Vehicles built before 1992 typically have Mechanical Fuel Injection and will need the Open End Wire cable and may require the installation of a speed sensor.

  • Vehicles built from 1992 to 1995 with Electronic Fuel Injection may have a 6-pin connector, a special OEM connector or no diagnostic connector port.
  • Vehicles built before 1996 may have the 6 pin configuration, a special OEM connector, or no connector.
  • Vehicles built from 1996 to 2001 generally have the 6 pin configuration.
  • Vehicles built from 2002 to 2006 may have either the 6 pin or 9 pin configurations.
  • Most 2007 and newer vehicles have the 9 pin configuration.
  • Vehicles built after 2016 may have a 9 pin GREEN configuration
  • Mack/Volvo vehicles built after 2014 have the 16 pin OBD II configuration.
  • Light-duty trucks and vans generally have the 16 pin OBD II configuration.

How does the VDO RoadLog report duty status change locations?

The VDO RoadLog will automatically associate a GPS location with the closest large population location. It may happen that this location is further away from you than another location that you know is much closer. For example. If your vehicle is in Fogelsville, Pennsylvania the system will label it as 7 miles west of Allentown, Pennsylvania, since Allentown is a local location with a large population. This is consistent with FMCSA’s requirements in ELD regulation and compliance.

The ELD rule requires that an ELD device is able to accomplish the Roadside Data Transfer to enforcement via local method Bluetooth or USB or wireless method Web services or E-mail.

However, as of this time, enforcement is not ready to receive the data via any of those means. FMCSA is currently working on building an infrastructure to receive the data and to train the enforcement.

As of right now, the most practical method of doing roadside inspections is either by showing the ELD screen or by ELD printout. Having the VDO RoadLog paper print-out may save drivers considerable time in inspection stops.
