CAT ET Adapter 3 Communication:

Allows communication between service tools and engine controls using various data links such as J1939/11, DeviceNet (future release), CAT DataLink, and J1708 (ATA) vehicle networks;
Flash program allows adapter firmware upgrades as additional features become available;
Uses J1939/11, high-speed data link (part of ADEM III controls), substantially reducing flash times;
Automatically selects J1939/11 when flashing the engine (reduces the flash time approximately 80%, from 14 minutes to 3 minutes). 

Designed to run with Microsoft Windows 95, 98, 2000, NT and XP
Ready to use, just install software program onto PC using provided CD
The PC-based service tools from Caterpillar provide the capability to access Electronic Control Modules (ECMs) from a personal computer. Many job-critical tasks can be performed with an electronic service tool. The user can display the status of a group of parameters (temperatures, pressures, etc.) simultaneously, view active and clear logged diagnostics, display the current configuration of an ECM and much more. The service tool works with a communication adapter to allow connection to an ECM. A graphical interface makes this software quick to learn and easy to use. The version and identification of the ECM is automatically retrieved and is displayed on a summary screen when the program is started. Diagnostic tests and calibrations can also be performed.
Caterpillar PC-based tools enable service technicians to reprogram ECMs, reconfigure control system parameters, fine tune performance or diagnose the root cause of a failure the first time. These powerful tools allow service personnel to display and analyze vital performance and health information from any system quickly and accurately. The service tool communicates with any system using ATA (J1708), J1939 or the Caterpillar proprietary data link networks. The service tools provide information and features needed to help a technician diagnose problems and perform repairs and to customize and personalize the operation of a product. By allowing customers to design flexibility and configurability into a product, Caterpillar service tools stretch beyond the capabilities of preprogrammed ECMs or onboard display systems.

Display graph and log status parameters.Retrieve prognostic data including histograms, engine totals for fuel used and miles traveled.View active diagnostics and clear logged diagnostics. View events where irregularities have occurred and have been logged by the ECM.Perform calibrations to enhance performance of the ECM.Customize the ECM with application-specific settings.Over 100 custom Diagnostic, Information and Service features including:2D and 3D Histogram plotting capability (engine software support required).Custom Status screen groupsSnapshots (Download and display snapshot data recorded by the ECM)Configuration Aid that allows upload/download of same configuration to multiple control modulesCustomized Service Tool OptionsCustomized service tool nameCustomized graphics for the splash screen and iconsCustomized installationAftermarket differentiation, the tool for one customer does not work on the product of another customer.Licensing options for customer managementFlash programming of the ECM(s)Training demonstration allows familiarity with the toola s primary functions without connecting to ECM(s)Major operating systems support (Microsoft Windows 95, 98, NT 4.0, 2000, ME, & XP)Perform customized diagnostic tests to identify harness problems, cylinder or component failures (Automatic Cylinder Cutout with cylinder to cylinder fueling comparison)

Q1:  Is the Cat Comm III compatable with the software CAT caterpillar ET 2011B Is this an actual caterpillar part or a knock off? Thanks
A1: Yes, this is actually the genuine CAT adapter,  It is also the ONLY recommended adapter for CAT ET, but obviously other ones will work. It will work fine for the version you have, and 2011C is actually the newest version.
Q2:  What is the difference between a cat comm II & Cat Comm III. Is one just a usb connection and one serial? Also, will this unit work with my Cat 3126B marine units? Seriel no. 3GS01797 Thanks
A2:  CAT Comm II was a serial port model, but since computers are no longer made with serial ports, they changed the design to a USB and called it a CAT Comm III. So you are correct. This unit works with all CAT engines -- Marine, on-highway, and off-highway. On Marine units, I'm not sure where they put the plug, but it should be somewhere near the ECM (Typically). It should be either a 6 pin or 9 pin connector.
Q3: Does this work with CAT 3500 natural gas engines and 3600 natural gas engines? Thanks.
A3: If those programs use CAT Electronic Technician (CAT ET) for the software, it will work.
Q4: Can the cat communicate 3 also be used to read detroit and cummins engines if I have the correct software?
A4:  Yes, it reads both J1708 and J1939 so it can read both of those. Keep in mind that this adapter only comes with the J1939 adapter end, so I would recommend purchasing the J1708 adapter end from me as well if you plan on connecting to some older stuff.
Q5:  will this unit allow me all access to the ecm to alter all areas eg set speed limiter to a lower speed and is there a yearly lic fee.
A5: This device is what you should use if you will be hooking up to both off-highway & on-highway CAT engines. If you are strictly wanting to work on on-highway CAT engines, I would rather see you purchase a Nexiq USB Link .The Nexiq USB Link is universal (Works with CAT, Cummins, Detroit, Allison, etc...), it is cheaper, plus it has bluetooth so you can go wireless.
Q6: want to compare the communicator and some caterpillar ECMS could tell me if it works with them.
A6: This item works with all CAT ECMS -- Off Road and On Highway, trucks and equipment

I have a Comms 3 that work with 2008 need to upgrade to 2013B do you sell only the software or must i buy the complete set

Dear Riaan,
Our CAT ET software is 2011A , not 2013B.It\'s better to buy the complete set,becase different manufacturers drives are not the same, hardware and software together is the most perfect.
Wish you a nice day.

Compre esta interfase a una empresa en Argentina, la verdad lo probe con una maquina caterpillar y no lo reconoce, esta interfase vino de china y no es original de caterpillar, la verdad son unos chantas, dicen que son originales pero la verdad son chinos, hasta los tornillos son comunes, encima vino tapado con unos sticker tapando el calco CAT.
