how to upload program from RCM-3000 to PC?

I need to reprogram the RCM3000 but I don’t have the source file. I have the another RCM3000 and I want to upload the source code from one and download it to another one, so how to do that? how can i do that by Dynamic-C software?

You might be able to use this sample (extract flash) to get a .BIN file from the RCM3000 using Dynamic C. Directions on how to use it are in the comments at the start of the file.
