Dearborn Protocol Adapter 5(DPA5)
Dearborn Protocol Adapter 4 Plus
-Dual CAN, BlueTooth Wireless, RP1210 A/B Compliant

The DPA 5 continues the Dearborn Group DPA family tradition of being the fastest, most rugged, most reliable, and most versatile RP1210 Vehicle Datalink Adapters (VDAs).

The DPA 5 is a One-Tool-Solution, supporting all of your favorite OEM and component diagnostic applications. So why purchase multiple adapters, when the DPA 5 is all you need?

From inception to deployment, the DPA 5 was built for speed-critical applications such as End-Of-Line (EOL) programming stations and the re-flashing of Electronic Control Units/Modules (ECUs/ECMs). In fact, the DPA 5 was significantly faster than the other leading adapters in an 〝apples-to-apples〞 benchmarking comparison. This means significantly reduced reprogramming and diagnostic sessions, leading to a fast return on investment (ROI)...
The DPA 5 has Dual CAN communication channels. This allows the DPA 5 to communicate with vehicles having two separate CAN data buses, such as the Freightliner Cascadia.

Not only is the DPA 5 a great product, but our warranty, support, and service are second-to-none.
  • The DPA 5 comes with a no-hassle two-year warranty.
  • Our technical support team has years of industry experience to help you get the most from your investment.
  • Should something go wrong, the RMA repair process is simple, and turnaround is generally same-day.
You Asked for 〝Out-of-the-Box〞 Functionality and we Delivered - DG Diagnostics!

Our customers have been asking for a simple diagnostics application that will work with their DPA 〝right-out-of-the-box〞 to display faults, component information and basic vehicle parameters from the J1708/J1587 and CAN/J1939 data buses. DG Technologies has answered the call and is providing these features in an application called "DG Diagnostics". 

DG Diagnostics is a great screening/triage tool and is provided free-of-charge with the purchase of any DPA product. DG Diagnostics works with all DPA adapters past and present, and may reduce your need to purchase full-featured OEM software.

Take your DPA straight from the box and start generating ROI with some of these features: 

  • Read and display J1587 and J1939 faults in 〝text〞 form. Request clear of inactive J1587 and J1939 faults.
  • Display 〝total-vehicle〞 and 〝trip data〞 such as odometer, engine hours, and fuel economy from the J1587 and J1939 data buses.
  • Create a viewable/printable/saveable vehicle report in HTML format showing all information that has been captured.
  • Display common 〝dashboard〞 parameters such as RPM, temperatures and pressures from the J1587 and J1939 data buses.
  • Request reset of J1939 trip information (trip odometer, trip miles, trip fuel, etc).
  • Display J1587 and J1939 ECM component information such as VIN, Make, Model, Serial, and Unit Numbers.
  • Record data bus data for engineering analysis as well as play that data back internally through the program or externally to the data bus.
  • Configure and launch OEM applications directly without having to navigate through the Windows Start Menu.

Below are images showing some of the functionality within the DG Diagnostics application.
