Every Thermo King Vehicle powered system requires a unit specific configuration file to be loaded onto the DSR
controller either at the factory or at the installing dealer depending on which options are being added. The
configuration file must be loaded using WinTrac 5.7 or newer, a 204-1126 DSR interconnect cable, and a 42-575 USB to
serial adapter.
IImmppoorrttaanntt:: Any unit getting the coolant heat / electric heat option will need a new configuration file loaded by the
installing dealer.
The configuration files can be found on TSA Info Central using the following path: Home > Software Downloads > Truck
and Trailer > Microprocessors > Truck Microprocessor Updates > Vehicle Powered.
