Key features, functionality and benefits


The ST900 Engineering Systems are configurable data logging systems offering the best combination of professional Data Logging hardware and software, packaged for optimum ease-of-use. Designed to be connected to any Stack dash display module, or in combination with the Stack video solutions, systems can be built up from a range of standard hardware modules.


Modular System Concept Explained

Stack systems are specifically designed to be of a modular design, which is an approach with a number of inherent advantages over other types of PC based or rack mounted systems:


CAN Based Concept Explained

The systems modules are all connected together by a CAN (Controller area Network) bus. This is similar to networking PC's together in an office, but CAN is a much more robust protocol, specifically designed for use in automotive and other harsh environments. Some of the benefits of a CAN based modular system include:



Frequently Asked Questions
Q. How do I calculate worst case message delay times and data bandwidth?

The Embedded Systems Academy offers a free online calculator:

After entering the desired baud rate, the length of the shortest CAN message (enter number of data bytes in your shortest PDO) and the length of the longest CAN message (enter 8 - SDO message is always 8 bytes long) hit the "Calculate" button.

The form gets updated and shows you an approximation of the expected timing behavior. It is an approximation only, as CAN uses stuff bits - so the exact message length varies slightly with data contents.

Further information can be found in our Troubleshooting Knowledgebase and FAQ sections.
