-Serial2 protocol selection is best configured using the WebUI but can also be configured using the LUA script. - -Open the WebUI as described in section "How to get to the Web UI". Scroll down to line Serial2 protocol and choose the desired. - -

It transports up to 16 full res channels at a rate of 100Hz and is mainly used to provide digital channel data to Flybarless Control Systems for helicopters and older Flight Controllers.
