Our datalink adapters are designed for use with GuidanzTM and allow communication with the on-board Electronic Control Module (ECM) for vehicle subsystems (e.g. Engine, Transmission, Brake Systems).

For more information, or to purchase Cummins datalink adapters, contact your local Cummins Distributor or call Cummins Customer Support (your regional phone number can be found at the bottom of this page).


Software Downloads


Your company’s firewall may inhibit the installation of this file. Please contact your system administrator for assistance if you receive such a message.

NOTE: If you have an INLINE 6 adapter, you must install the INLINE 6 PC Driver that is included in this software. The INLINE 6 Software installation is a typical Windows-based, self-executing installation. The executable setup file (listed below) installs the latest INLINE 6 PC Driver, which allows RP1210-compatible software applications to communicate with the INLINE 6 adapter. The latest version of the reflash utility and latest version’s firmware are also included in this download and will be installed automatically in their proper folders in your PC when you run the install program, as described below.



Technical support is no longer available for INLINE 6 and it will be obsoleted at the end of 2022.

INLINE 7 is currently certified for use in several regions where it can be used as a replacement for INLINE 6.

Regions without INLINE 7 certification can use an aftermarket RP1210 compliant adapter.
