Unless someone on the board has got one working and willing to advise on the supplier, then the only sure option is to buy an original. In the above example you can see how its possible that some multiplexor copies will work and some wont. Very few people can do the latter, so most will have to guess what the microcontroller is doing through trial and error. A reverse engineer could either guess what and how the microcontroller is working or he can spend a lot of money to slice the microcontroller to gain direct access to the silicon substrate. A microcontroller is a single chip computer with internal program memory which is protected from being read. The engineer could have written software on the PC to toggle the RTS output of the UART controller to emulate a shift register, but due to various timing constraints of different laptops, he embedded a microcontroller into the multiplexor for this task. MB carsoft 7.4 interface software can use on Windows XP system. Carsoft 7.4 multiplexer can read and erase all fault codes. ![]() Being copies the engineer who reverse engineered the CarSoft original would have had to get it exactly right.įor example, please excuse the basic explanation if you already know microcontrol theory, but suppose CarSoft needed a serial shift device to send data between its multiplexor and an on-board car computer. Mercedes benz carsoft 7.4 is Benz Diagnostic Tool. ![]() Click to expand.Unfortunately I cant say because Ive not played with them.
