Reading the manual, if I have two Sport EX displays, both have an adaptive AHRS inside. If I’m using one as PFD and the other as MFD, and the PFD AHRS should fail, it should be the case that the MFD AHRS takes over. Does this require a dedicated serial port on each display or does interdisplay serial connection serve this function? I’m trying to determine how many serial ports are needed.
Currently the Sport EX displays do not share AHRS data. The plan is to use the display link in a future software update. Running the link as fast as possible will be recommended. You can use 115200 for direct connections between EX ports.
