Detroit Diesel Software, Which is Best for You? [Standard or Pro]

Detroit Diesel laptop-based software was made available in the early 2000s. It replaced the software that was most commonly found in the Prolink 9000 or Nexiq Grafiq hand-held scanner. While these tools were great in their time, they became outdated due to small screen size and when Detroit Diesel started writing their software for laptop computers.

Detroit Diesel software has generally always impressed the mechanics with its simplicity & ease-of-use. Versions prior to 8.0 open very quickly. The version 8.0 & newer do take longer to open but this is because the software package is so large in comparison to the older version. (note: a newer, faster computer will open & operate the Detroit software faster)

Detroit Diesel Diagnostic Link [2007+] software is designed for these systems:
  • Detroit Diesel powertrains
  • Freightliner Cascadia *

Detroit Diesel Software Computer Requirements [Minimum]

  • Windows 7, Windows 8.1, or Windows 10 (32/64bit) [Note: Win 10–64 Pro recommended for maximum performance]
  • 2.0 GHz Dual Core Processor or faster [2.4 GHz or higher recommended]
  • 2.0 GB RAM or more [with the newer software it’s recommended to purchase a minimum of 8 GB RAM for any truck diagnostic computer. The only exception is Cummins Insite which requires 12 GB RAM]
  • 40 GB Hard drive or larger (with 20 GB free)
  • Monitor and graphics card supporting 1024 x 768 resolution and 16-bit color
  • 1 available USB port
  • High Speed or Broadband Internet Connection
  • RP1210 Compliant Interface [USBLink2 interface is recommended]
  • Administrative Rights (for installation)
  • IT security firewall access for TCP port 48481 for outgoing and incoming traffic

Computer Recommendations

  • Business or field grade computer (Recommended Examples:)
  • Panasonic CF-31
  • Panasonic CF-54 or CF-53
  • Dell Latitude & Latitude Rugged

These recommendations are for ruggedness; the computer still must meet Detroit Diesel specs (see above).

Not Recommended:

  • CF-30 (Last built in 2010, too old, insufficient processor speed, etc.)
  • Any home use computer (Acer, Asus, HP) as they have an increased failure rate in shop use.
  • Computers without Windows Pro operating system

It’s always recommended to spend a little extra when purchasing your diagnostic computer. Do your homework. It’s better to have a computer that provides some room for the ever-growing demands of the software. With any computer, make sure it has the capability & capacity to run the software you plan to install. If either of these are insufficient it can affect the operation of the computer.

Areas of greatest importance are:

Operating System:

  • Windows 7: It is a great system, but Microsoft is scheduled to stop supporting it in January, 2020. Yes, Win 7 systems will continue to work after that time but Microsoft will no longer provide support if you call them after this date.
  • Windows 8, We recommend not to use it, too many problems.
  • Windows 10 Pro 64 bit: Why use 64-bit? The 32-bit system only “sees” 4 GB RAM. The RAM demands of the newer software are generally at 4 GB, 8 GB or 12 GB…..and they are increasing. Insufficient RAM slows down the opening & operation of the software. Problems such as these are hard to pinpoint & can waste your time.


  • We recommend a minimum of 8 GB RAM to our customers or 16 GB RAM if running Cummins Insite. Insufficient RAM slows down the opening & operation of the software.


  • Intel i5 2.0 GHz speed is generally considered a minimum in today’s environment.

Hard Drive:

  • Solid State hard drives process data faster & are less prone to damage if a computer is dropped. Since semi-rugged & fully-rugged (MIL-STD-810) computers already protect their hard drives to a certain degree, a solid-state hard drive is not required, but it does provide just that much more protection.
