IMPORTANT NOTE:  As the diagnostic and reprogramming software applications have evolved, the requirements for additional computer storage capacity and memory has increased. Please review these computer specifications carefully and take any necessary steps to update your hardware as needed.  

Component Recommended • Windows XP, Windows Vista or Windows 7 (32 & 64 bit) • 1.8 Ghz processor • 2.0 GB RAM • 40 Gigabyte Hard drive with 20 Gigabyte free • 32x CD ROM Drive • Monitor and graphics card supporting 1024 x 768 resolution and 16-bit color • 1 free USB port • Internet or Mainframe Connection to DDC Server (for updates) Hardware Adapter Device (One of the following) › Nexiq MagiKey device with parallel cable| › Nexiq USB-Link with USB cable (Required for Cascadia diagnostics)

 * Laptops purchased from Detroit Diesel beginning in August 2006 through May 2011 meet the minimum specifications. Any purchase prior to this time may need additional memory (see recommended specs). As a general rule, computers with higher levels of RAM perform more efficiently. Computers with only the minimum specifications should work, but they may run slow. Closing unused applications while running DDDL/DDRS may also help.  

The Nexiq USB Link is the approved translator interface for Detroit Diesel.  Bluetooth functionality is not approved for reprogramming.
