[CA] [CA11] STLK Fail Lightning Issue

[Chuck - Raymarine - Moderator]

svbloom,

General Comment: Regarding inquiries to specify the part number for every cable to be purchased, it would not be possible to do so as the cable routing lengths differ per every vessel's unique cable routing. However, we can provide information concerning the types of cable(s) required and provide links to the web pages were customer may view the available cable lengths.

Q1a) I read online that there is a iTC-5 transducer converter kit that may be needed for speed/depth/wind. Is this the case?
A1a) As you will be replacing ST60 Tridata and ST60 Wind instrument with i50 and i60 instruments respectively, an iTC-5 would not be required unless you are seeking to use the i70S to calibrate depth, wind, speed, and temperature sensors or should you not desire to run the cables for the associated transducers through the binnacle tubes into the instrument pods. The latter would also require that the i70S be installed to support SeaTalkng / NMEA 2000 communications rather than SeaTalk communications as you had suggested, but would significantly reduce the amount of cable chased through the binnacle tubing.

Q1b) Do I need just one kit, or one for each transducer?
A1b) If installing an iTC-5, then only one iTC-5 should be installed.

Q1c) It is still a possibility that the transducers were affected also by the lightning. if this is the case, we would need to replace them.
A1c) Lightning strikes may result in damage to transducers as well. The only way to determine whether the transducers have also been damaged would be to test them. While FAQs (see the Instruments category of this Forum) are available for testing wind STW, and water temperature sensors, specialized equipment is required to test depth transducers. It may be necessary to connect the currently installed transducer to a working depth instrument which in turn as been suspended in water which is at least 3' deep to determine the transducers operational state.

Q2d) I assume we'd also need to run all new wiring then? (The wiring through the mast for the wind transducer is my biggest concern).
A2d) Wiring may or may not be damaged by a lightning strike.

Q2a. Is there a diagram available at all for how the wiring would run for this setup? (ie. what is connected to what, etc.).
A2a. Networking information is provided within the Product Documentation for each Raymarine product. Unfortunately, we do not have the bandwidth to produce custom diagrams. However, we can provide comments on diagrams submitted by customers. Some larger Certified Raymarine Installers may be able to produce such diagrams for fee for customers who purchase equipment from them.

Q2b. I assume upgrading everything to STng will mean no ST to STng converters or junction blocks needed, but possibly the iTC-5 converter mentioned above.
A2c. Interfacing the new products via SeaTalkng / NMEA 2000 would indeed eliminate the need for a SeaTalk to SeaTalkng Converter, a D244 SeaTalk Junction Block, and a SeaTalk to SeaTalkng Adapter Cable. These items would be typically be replaced with a SeaTalkng 5-Way Connector and a length of backbone cable which would connect the binnacle mounted instrument pod to the binnacle mounted pod for the MFD. As indicated within the FAQ found here, a SeaTalkng T-Piece or SeaTalkng 5-Way Connector would typically be installed within the binnacle mounted pod for the MFD to connect the MFD and backbone cable from the instrument pod. Should the p70S autopilot control head be located in the binnacle mounted pod for the MFD or in its own pod which is attached to the binnacle, then an appropriate length of Spur Cable would typically be used to connect it to the SeaTalkng 5-Way Connector installed within the binnacle mounted pod for the MFD.
