Data Tester

When you procure new buses, you need to ensure that they meet the requirements of the contract. They must have the right technical properties, but also the content of the data interfaces is important as they supply your IT systems with important information. As it stands today, these digital interfaces cannot simply be checked. This is where the Data Tester can help you with a simple plug and play solution that gives you a report with the information you need in just 3 steps.

Get what you pay for

Your buses must have certain characteristics to meet the demands of your fleet. This applies to hardware and technical features, as well as to software that controls your equipment and supplies it with data to ensure seamless integration. Our Data Tester helps you to quickly see if the software and data match what you have ordered.

Why is data quality important?

The applications powered by vehicle data can only be as good as the quality of the data. Reliability is the be-all and end-all for fleet operators. Data helps at this point to make better decisions, among other things. The basis for this is decided when purchasing the vehicle: What data is available and how? Here is an example of an evaluation of the signal temperature in the interior.
