When more than one display is installed, the AFI4700s will
communicate with each other via an RS-422 serial interface crosslink
bus. In order to provide assurance of data accuracy, the EFIs
constantly compares attitude, heading, localizer, glideslope, and radar
altimeter information between the two displays. The crosslink bus also
allows the display of offside attitude and heading.
