Section 6 – SR-2 Service Procedure A46B
Preparing flash load files for use by Wintrac
Flash load files must be prepared for use before the Wintrac flash load process can be started. To prepare the
files proceed as follows:
1. Using Windows Explorer locate the sub-directory containing the files. The files will be in the format
“Microcode Update 65xx for SR2 HMI Control Panel.exe” (where xx = the software revision)
or
“Microcode Update 66xx for SR2 HMI Control Panel.exe” (where xx = the software revision)
2. Double click the desired file. The file will be uncompressed and installed in the sub-directory
Wintrac\Flashload\SR2. If this directory does not exist it will be created automatically. There will be two files
in this sub-directory.
The software files are now ready for flash loading using Wintrac.
Connecting the Cables
The same cables used for downloading are required to perform a flash load. Typically two cables are used to
connect the computer to the microprocessor as shown below.
Data Cable The data cable has a 9 pin “D” connector installed on one end to attach to the computer and a 15 pin
“D” connector on the other end. The cable is available as either a 20 foot or 50 foot cable as shown below.
Adapter Cable An adapter cable is required to complete the connection to the microprocessor or data logger.
This cable has a 15 pin “D” connector on one end and a 5 pin Deutsch connector on the other end. The 15 pin
“D” connector is attached to the 15 pin “D” connector on the data cable and the 5 pin Deutsch connector is
attached to the Cargo Watch
connector above the HMI Control Panel. Do not attach the cable to the Service
Watch connector.
