Caterpillar ET 2011A Windows XP78 Install Tutorial

I wrote a guide to install it and I uploaded the patch and the drivers here, including how to solve the connection trouble on the Windows XP SP3 computer (Error #434: The requested baud is invalid) This is because you need to patch ET 2011A.

I know that anything isn’t going to work like the original, but at this time is the tool I have in my hands.

For those like me, I upload the files and I put the links on the attach bellow:
Cat ET 2011A PATCH!jQpgQbJY!hlywN6fLOA_1iojqdj0kToQRWrFsnHPDWiBHCJNEag0


CP210X USB to UART Driver!iJxhwAbZ!Ph3OtDQAr1l-uKckoBe1Rg51_l3rKpUKcaI3hNpv4bY

FTDI USB to UART Driver!TY5ijLqD!o_ZVBqU5jVeQjPrF3_VjyApMbYf0TLLPf_mjvbC3IzM

Here a leave the instructions:

*   Clean install
*   Install ET 2011A
*   Install FTDI USB to UART Driver
*   Install CP210X USB to UART Driver
*   Open the ET 2011A. Click “Utilities” > “License Cat ET” > Generate code and paste it.
*   If your OS is Windows XP goto step 7 or Windows 7/8 goto step 8.
*   Copy “CommunicationAdapterServer.exe” to “\Program Files\Common Files\Offboard Information Products”
*   ONLY IF WINDOWS 7/8. Open Cat ET 2011A Patch. Select unit and os guest (32 or 64 bits). And click Patch, it would show you Patched it message OK.
*   Reboot computer.
*   Connect USB and bluetooth and wait to install and disconnect them.
*   Go to properties on “My computer”, open hardware management and check USB and bluetooth com port number.
*   Open the ET 2011A and goto Utilities->Preferences->Communications

Select “Heavy Duty Truck diagnostic Scanner Caterpillar Comm Adapter II (Dual Data Link/Serial lP)

Select the same COM port as you noticed in step 11 (USB or bluetooth the one you already connected. 1 only)

It works now. I tested it on a Cat 950G and it show me the 3 ECM, however I’m having trouble to connect with a Cat 416E, I get the message check cable connection, no cable detected.

But it works perfect on a Cat 950G.
