Question : What does the EFS feature on the USBC-H-422/485-M PRO / USBC-H-422/485-M-ISO PRO series do?
Answer : The EFS (Extra Fail Safe) feature is similar to the biasing feature found on our other converters. It helps to bias the data lines to the idle state when no node is driving the bus, preventing spurious data which may be received if the lines are floating.
Like the other features in our PRO series, the EFS biasing is built into the converter avoiding the need for external components, and is enabled/disabled easily via our configuration tool. The EFS LED illuminates in a steady green colour to provide a clear indication when this feature is enabled.
