Because I had to get back to my office in Munich, we finally had to abandon our course and sail to Newport, RI. We headed north for six days mostly in 20-25 knot easterly winds. Uncommon weather patterns made the 800 nm trip exciting and fast, taking six days at an average speed of 5.7 knots.įrom Bermuda, we planned to head for the Mediterranean with a stopover in the Azores but the irregular winds allowed no easterly course. After a short stay on Green Turtle Cay, we headed for Bermuda in May 1992. The boat was launched in December 1991 in Palmetto, Florida, and sailed down to Key West and around to the Bahamas. Am I creating the potential for a monster if the autopilot, connected to wind and speed by ST1 and to the plotter by NMEA 183, is now connected to NMEA 2000 via the ST1 network? Do I also need to link the autopilot to the plotter via the ST1 converter through NMEAA 2000 or can I leave the existing connections alone?The extended first voyage of Caliber 38, included every condition from sunny skies and light winds in the waters off Florida, to howling gales in the North Atlantic, before arriving home, some 6,000 nautical miles across the Atlantic Ocean. At this time the NMEA 183 network and the NMEA 2000 network are separated as the only thing on the latter is the sat weather receiver and plotter. Do I need terminators on the converter? This is my main question.Įverything works well now. Connect converter to NMEA backbone with drop cable.Ĥ. ST1 and NMEA 2000 networks are already powered so no power needed to converterģ. I connect the converter to the Seatalk 1 system through an existing ST1 junction block.Ģ. I just purchased the Raymarine E22158 converter but am unsure of the connections/terminators.ġ. The plotter is connected to my S1 autopilot by NMEA 0183, and to satellite weather by NMEA 2000, so I already have NMEA 2000 going to the plotter. I want to connect my Raymarine ST60+ wind instrument to my Garmin 541S chartplotter so that I get a readout of VMG on the plotter. I currently have no wind information going to my chartplotter and this prevents me from getting some useful data. ![]() I just found this older post which addresses my project. Having two sources of power can create a potential for ground loops. #4 If the ST1 network is already powered, and you are connecting to an already powered N2K network, you need to disconnected the red power feed wire for the ST1 network. I've seen DIY installations using in excess of 12 terminators and no, the systems were not working. #3 CAUTION: Only two terminators per N2K network. Terminators are only used at either end of a back bone otherwise you would use Raymarine "blanking plugs" in drop ports or NMEA 2000 "blanking caps" to protect any unused future expansion ports. #2 If the E22158 converter is the end of a back bone, as shown here, a blue terminator would be used. #1 If the E22158 converter is used only as a drop device to port ST1 over to N2K, and is not at the end of a back bone, or in a backbone, you would not use any terminators in the blue ports. #AUTOHELM 2000 REVIEW UPGRADE#This upgrade will run you slightly over $100.00 to get your SeaTalk 1 data converted over to NMEA 2000 based electronics. YOU CAN NOT DO THIS! It requires proper language conversion.Ĭonnection to a standard NMEA 2000 network will look similar to this: WARNING: I have seen a number of individuals physically damage equipment or disable a complete N2K system by trying to hard-wire an older ST1 network to STng or NMEA 2000 networks. #AUTOHELM 2000 REVIEW SOFTWARE#The ST1 to STng converter is actually a small electronic signal converter that has operational software doing the conversion & its not just a bus or "fancy terminal strip" as some assume it is. You just need a Raymarine E22158 ST 1 to STng conversion kit and either a male or female STng to NMEA 2000 drop cable:Ī lot of folks don't realize that STng is essentially NMEA 2000 and once your ST1 data is converted into STng/NMEA 2000 the conversion & connection to the rest of the vessels N2K bus is simple. The conversion from ST1 to STng/NMEA 2000 is simple: Most often the question is related to the older ST-60 instruments that operate on the SeaTalk 1 network. I get asked this electronics question more than just about any other from customers who have a perfectly operating Sea Talk 1 network. ![]()
