Mobile plug & play WIFI data node for PTI

Interconnected Periodic Technical Inspection


From 01/01/2020, the brake forces determined on a brake tester must be transmitted via the standardized ASA livestream data interface as part of the main inspection of passenger cars and trucks. The test engineer must transfer the brake values in a tamper-proof manner to his PC-based production system and evaluate them live.

Back in 2014, we recognized the need for a simple, intelligent and compact solution. As part of the feasibility study and in exchange with the PTI organizations, customers and service teams, the idea became a “market standard”!


We developed various prototypes in different expansion stages. The final sample, NPC-2016, was convincing and became a series device – a big step towards digital main inspection.

The NPC-2016 offers a stable Wi-Fi network for the main inspection in test stations or in subsidiaries, as well as the connection to the brake tester and other workshop equipment. The product is compatible with all German main inspection applications widely used in the market and connects the brake tester via the ASA livestream interface, the HU21 adapter and the production system for the main inspection work processes.

The intelligent PTI algorithm adapts individually to the respective test environment and workflow. The integrated ASA network manager handles the communication of all participants and sends the measured values of the brake tester (and other test devices) live to the production system of the test engineer. The sturdy ABS plastic housing and the integrated rechargeable battery (runtime > 12h) guarantee a long service life, even in tough test environments whereas the recessed magnetic holder allows the NPC-2016 to be attached effortlessly and securely to the test equipment.

Successful market distribution:

Within three years of product launch, Cartesy has achieved over 90% market penetration. Currently, 10 out of 11 German PTI organizations (DEKRA, GTÜ, TÜV Nord, KÜS, etc…) use the mobile data node. By the end of 2021, more than 13,000 inspection engineers were already equipped and performing main inspections with the help of NPC-2016. In addition to the innovative technical solution, a key factor in the product’s success is its visual appearance and the possibility of branding the product to customer specifications.
