Cat Et Connection Cable

CAT ET connection cable is the original connection cable that provides communication between the electronic control units (ECU) of Caterpillar construction machines and the computer. When used with Caterpillar's Electronic Technician (CAT ET) software, it enables machine fault diagnosis, parameter calibration, software updates and live data monitoring.

It provides reliable performance under severe job site conditions thanks to its high quality conductor structure and durable insulation. It has a long service life against challenging environmental effects such as vibration, temperature changes and humidity.

This cable is an indispensable part for Caterpillar service teams and technicians in diagnostic operations.
