Flexray Physical Layer Module Connector (X3, X7) - Fujitsu MB88121 SERIES User Manual

4.5 FlexRay Physical Layer Module Connector (X3, X7)

To use the FlexRay physical layer driver module from TZM (FT1080) there are two special
connectors on board of SK-91F467-FLEXRAY, both for FlexRay channels A and B, to insert
the modules. If the modules FT1080 should be used, it is necessary to disable the RS-485
driver modules (see chapter 3.6).
