on start up, and a pop up window that says, "No Seatalk
HS Connection Detected."
The raydome is the RD418D that came in the kit and the connection is via a crossover coupler. The radar fires up but I'm wondering why I'm getting the error message and what it means. Anyone know?
Found this on t'web .. Hope it helps, note the 4th paragraph...:
In order to use an e7/7D/c95/c97/c125/c127/e95/e97/e125/e127 MFD's radar features, the MFD must be interfaced to a Digital or HD Digital Radome or HD/SuperHD Open Array Radar Scanner. The digital radar scanner cable should not be cut.
A Digital Radar Scanner Extension Cable (2.5m (A92141D), 5m (A55080D, or 10m (A55081D)) should be chased from the Digital Radome to the base of the mast
. This will permit
the Digital Radar Extension Cable to be quickly and cleanly disconnected from the vessel's wiring
should the mast
be removed. The Digital Radar Scanner Extension Cable will be connected to a Digital Radar Cable of the appropriate length (5m (A55076D), 10m (A55077D), 15m (A55078D), 25m (A55079D)).
A digital scanner extension cable would not typically be used on a power boat
unless mounted on an arch or tower would was intended to be removed. In most power boat
installations, the digital radar cable will be plugged directly to the radar scanner. The digital radar cable in turn be interfaced to power and the SR6 Sirius Satellite
Weather/Radio Receiver / Network Switch which will in turn be interfaced to the MFD via a RayNet to RJ45 Cable (1m (A62360), 3m (A80151), 10m (A80159)).
Should the RayNet to RJ45 Cable need to be extended, then one may do so by using a SeaTalkhs Crossover Coupler and a SeaTalkhs Patch Cable (1.5m (E06054), 5m (E06055), 10m (E06056), 15m (A62136), 20m (E06057)). The power leads of the digital radar cable would have to be interfaced to a 12VDC or 24VDC power source.
