What is ISO 11992‑1 - Physical and data-link layers for CAN-based network interfaces about?
ISO 11992‑1 is the first part of the multi-series standard that describes the data link layer (DLL) and physical layer (PHY) for the two CAN-based network interfaces specified in the 11992-series.
ISO 11992‑1 provides you with guidance for communication between towing and towed vehicles which helps you reduce accidents while towing.
Who is ISO 11992‑1 - Physical and data-link layers for CAN-based network interfaces for?
ISO 11992‑1 on the interchange of digital information on electrical connections between towing and towed vehicles- Physical and data-link layers is applicable to:
- Vehicle manufacturers
- Towing equipment manufacturers
- Towing companies
- Towing and towed vehicle network developers
- Transceiver developers
- Device developers
Why should you use ISO 11992‑1- Physical and data-link layers for CAN-based network interfaces?
While towing a vehicle communication is very important. ISO 11992‑1 provides digital information interchange for towed vehicles, including communication between towed vehicles in terms of parameters and requirements of the lower OSI layers (physical and data link layer) of the electrical connection, used to connect the electrical and electronic systems.
ISO 11992‑1 gives a data link layer that provides the functional and procedural means to transfer data between network devices and provides the means to detect and possibly correct errors that can occur in the physical layer. Thus, this gives you a safety net in case the physical layer fails.
The data-link protocol in ISO 11992‑1 specifies how devices detect and recover from such collisions and may provide mechanisms to reduce or prevent them helping reduce accidents while towing.
What’s changed since the last update?
BS ISO 11992‑1:2019 is the third edition that cancels and replaces the second edition (ISO 11992‑1:2003) which has been technically revised.
- The main changes compared to the previous edition are as follows: wording improvements and clarifications
- introduction of requirement statements
- addition of informative Annex A, Implementation examples of the bus failure management
