Leverage Caterpillar connected data and security principles to improve efficiencies, increase productivity and make your business more profitable.
Remote Flash sends an alert from your Cat dealer, prompting you to update the software on your machine. To minimize downtime, updates can be deployed while on the jobsite without having to wait for a dealer technician to arrive. Remote flash decreases maintenance time and keeps your asset running with maximum efficiency.
Remote Troubleshoot allows your Cat dealer to run testing while the machine is operating. Once the problem is identified, a technician can fix it with the correct parts and tools the first time, saving time and money. Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency.
VisionLink™ is a cloud-based software application that takes the guesswork out of fleet management with key insights to maximize performance - regardless of fleet size or equipment manufacturer. Receive equipment data seamlessly to your desktop or mobile device, all from a convenient centralized solution to make informed decisions at every turn.
