Autel MaxiScan MS509 OBD2 Code Scanner MS509 DTC code reader

Here is the question:

When I try to connect it to my pc (I use windows xp sp3) the pc doesn’t recognise it. It recognise an “unknow device”. I have install the software of the cd but the problem remain. Also, the light of the display is on while the scanner is conected to the pc, but I can’t turn on the scanner while it is connected.

There is an answer for you:

Step 1: When installing the software from CD en pluggin the MS509 to your USB port, screen is lighting up en is OFF, I went to hardware manager in configuration screen (windows 7 64bit, and also in my XP sp 3)

Step 2: When the maxiscan ms509 is plugged in there is an USB RS232 something with RS232 with a message dat de drivers are not installed. Drivers are not included with the CD

Step 3: Just download for your OS and unpack to a new dir then in your hardware manager click on the RS232 and install drivers manualy, pointing to the drivers you just unpacked in a new directory.

Step 4: Now it shoud install maxiscan ms509 scanner drivers for de RS232 hardware (Serial to USB converter). After this your diagnostic MS509 will turn ON.

I’ve tried it in three different cars any every time it gets halfway through Diagnostics stage and it losses connection, I retry & does the same
