| N/A | Personal Computer (PC) | The PC is required for the use of Cat ET. |
| "JERD2129" | Software | For all engines and machines |
| 317-7484 | Communication Adapter Gp | One-piece communication adapter between the PC and the engine ECM |
| 171-4400 (1) |
Communication Adapter Gp | This group provides the communication between the PC and the engine ECM. The parts below are also needed.. |
| 7X-1414 |
Adapter Cable As | This cable connects the communication adapter to the service tool connector. |
| 237-7547 | Adapter Cable As | This cable connects to the USB port on computers that are not equipped with a serial port. |
| ( 1 ) | The 7X-1700 Communication Adapter Gp may also be used. |
Note: For more information regarding the use of Cat ET and of the PC requirements for Cat ET, refer to the documentation that accompanies your Cat ET software.
The Caterpillar Electronic Technician (ET) is designed to run on a personal computer. Cat ET can display the following information:
- Parameters
- Diagnostic codes
- Event codes
- Engine configuration
- Status of the monitoring system
Cat ET can perform the following functions:
- Diagnostic tests
- Sensor calibration
- Flash downloading
- Set parameters
Connecting Cat ET with the Communication Adapter
Use the following procedure to connect Cat ET and the communication adapter to the engine.
- Remove the electrical power from the ECM.
- If you are using the 317-7484 Communication Adapter Gp , connect the USB plug to the PC and connect the other end of the adapter to the engine's service tool connector.
If you are using the 275-5120 Communication Adapter Gp , connect communications adapter (5) to a communications port on the PC by using one of the following methods:
- Connect cable (4) between the "COMPUTER" end of communications adapter (5) and the parallel port of PC (1) . Be sure to configure Cat ET for the parallel port.
