If your system has a test port, a portable measurement meter from Silicon Labs can now add USB connectivity and minimize system changes without changing the original system or added risk! Take a look at our customer success story to find out more.  

Situation: A handheld meter supplier needed to add USB connectivity to one of their most trusted products but did not want to alter the original design fear of tampering with the meter’s operation, accuracy or calibration quality. They needed a strategy that would minimize unnecessary risks for their customers.

Solution: The answer to the problem was to connect a CP210x USB Bridge Device to the original system test pins. A small amount of programming firmware on the CP210x USB Bridge handles communications between the original legacy system and the host system, while the original meter design was left unchanged. This solution ensured that the meter would continue behaving as expected.
