ITC-5 i70s Wind Depth Sensors

Welcome to the Raymarine Forum olesenrl,

Please click here to view a FAQ addressing how to troubleshoot intermittent or failing SeaTalkng communications. Please click here to view a FAQ providing the pinouts for SeaTalkng Backbone and Spur Cables. Faulty SeaTalkng networking components, although very rare in systems featuring unmodified SeaTalkng networking components, may similarly be fault isolated by substituting components with operational components. The most common cause for SeaTalkng network communications failure is a SeaTalkng cable which has not been fully seated in the device or networking component's socket and/or failure to rotate the socket's locking ring into the locked position.

From your problem description, the marine electronics system appears to be limited following components:

- MFD's: No MFDs have been identified within this system

- iTC-5: Verify that the iTC-5 has been installed as a backbone component, not as a spur to the backbone. As with all devices having a SeaTalkng communications interface, it is recommended that you verify that it is been updated with the latest available Raymarine product software update. The software versions of products which have been interfaced to the SeaTalkng backbone may be determined via the command sequence MENU->SET-UP->DIAGNOSTICS->ABOUT SYSTEM from an i70 MFID. This same command sequence may be used to verify communications between devices on the SeaTalkng backbone.

- i70 MFIDs (2): Please see the command sequence above to verify communications between the i70 MFIDs and the other devices on the SeaTalkng backbone as well. Should one of the i70 MFIDs not be communicating with the other devices within the SeaTalkng backbone, then its software version may be determined via the command sequence MENU->SET-UP->DIAGNOSTICS->ABOUT DISPLAY). If each i70 MFID has been updated with the latest software and one of them is not communicating with the other devices within the system, it is first recommended that the MFD be reset (MENU->SET-UP->FACTORY RESET) and that it then be tested again. Should the problem persist, then the fault may be rooted within the i70 MFID's SeaTalkng communications circuitry or within one of the SeaTalkng networking components. By disconnecting the SeaTalkng spur cable from the problematic i70 MFID and then connecting then substituting the operational i70 MFID in its place, the problem may be fault isolated. Should this fault isolation indicate a problem with the i70 MFID, then it should be sent to Raymarine’s Product Repair Center to be bench checked / serviced.

ST6001: ST6001 is the product name for an autopilot control head. Autopilots using a ST6001 autopilot control head minimally consist of the autopilot control head, autopilot course computer, fluxgate compass transducer, rudder reference transducer, and drive unit. Of these, only the autopilot control head and course computer factor in troubleshooting the reported issue. It is unclear which model of autopilot course computer has been installed onboard. Please state the model of autopilot course computer which is installed.

AIS650: see prior comment regarding software updates. The AIS650 is designed to be updated via a SD memory card through it's SD memory card reader slot

Wind Transducer: After addressing the SeaTalkng networking, software, and troubleshooting points raised above, should the neither MFD detect wind, then the indicative of a faulty cable splice, cable failure, failure with of the wind transducer, or failure within the iTC-5, please note that we have had a limited number of customers report that moving the wind transducer's bare lead from the silver Wind Transducer terminal of the to the silver terminal of the iTC-5's speed or depth transducer positions corrected such intermittent wind issues.

The wind transducer cable may be tested by disconnecting the masthead and then performing a continuity test to check for both continuity and to ensure that no shorts (continuity sensed on more than one pin of the masthead mount) are detected. Should the cable test not identify any faults, then please click here to view a FAQ addressing how to test the masthead. Should the masthead testing not indicate a fault with the masthead, then the fault may be rooted in the iTC-5. Should the cable have failed, then it should be replaced. Should the masthead have failed and it has been purchased within the last 30 days, then it should be returned to the dealer or sent to Raymarine’s Product Repair Center to be bench checked / serviced.then it would be recommended that a Factory Reset be commanded to both i70 MFIDs and to the ST70 MFID (assumed). Should the problem persist thereafter.

Depth transducer: Unlike fishfinding products, the iTC-5 will not detect a Depth transducer source unless the transducer is able to receive bottom echoes. Such detection would require the boat be located in the water and that there be at least 3' of water beneath the transducer. Instrument depth transducers and most fishfinding depth transducers will not sense bottom echoes should the vessel be located out of the water.
