Jose,

Should the cockpit's MFD be verified to communicate with the radar transducer when when swapped with the navigation station's MFD, then there would appear to be a fault with either 1) the port of the SeaTalkhs Network being used to interface the cockpit MFD to the system's Ethernet network or 2) a fault within the SeaTalkhs Cable and/or adapter used to interface the SeaTalkhs Cable the cockpit MFD to the SeaTalkhs Network Switch. To fault isolate the problem, it would be recommended that the recommended that the SeaTalkhs cable connecting the navigation station's MFD to the SeaTalkhs Network Switch be unplugged from the switch and that it instead be connected to the port of the SeaTalkhs Network Switch which the cockpit MFD's cable is presently interfaced to. If after doing so, the navigation station's MFD continues to be able to communicate with the radar transducer, then the tested port of the SeaTalkhs Network Switch would be deemed to be operational and the fault would appear to to be within the cockpit MFD's SeaTalkhs Cable or adapter. Similary, if the navigation station's MFD is then unable to communicate with the radar transducer, then the tested port of the SeaTalkhs Network Switch would be deemed to have suffered a failure and it would be recommended that another port of the SeaTalkhs Network Switch be used.
