Introduction
This guide supports the installation of a DB3, which is an all-in-one door lock and override interface module in Remote Start Ready (RSR)
mode. RSR is a function that enables the DB3 to remote start the vehicle completely on its own. Consequently, there is no need for an
aftermarket or an OEM remote starter in order to start the vehicle from a distance.
This solution may offer up to four (4) configuration options to control your system (all sold separately):
• 3x OEM Lock Remote Start Activation: if applicable, refer to the “Vehicle function compatibilities” section.
• SmartStart Pro Compatible: SmartStart Pro is equipped with D2D, which means it can be connected to an interface module and used
in RSR mode without the use of a remote starter. See “Module programming” for more information.
• Digital RF Kit Compatible: This firmware supports D2D 2.0, which means Digital RF kits can be connected to the interface module and
used when in RSR mode (compatible with firmware version ending with .101 or higher only).
• XL202 & Analog RF Kit
Notes
• This module can only be flashed and configured using DirectLink at www.directechs.com.
• RSR mode is not compatible with vehicles equipped with a manual transmission.
