Well, Steve Thomas wins the Golden Thunder Mug.
Electric I understand, Electronic is beyond my scope of comprehension. How (see below) you can ignore a NMEA ground on the VHF end and take the NMEA IN ground, put a resistor on it, put it on the (NMEA IN) positive, (which to me = a direct short!) and Viola, the satellite icon pops up in the corner of the VHF, GPS Coordinates, time, the whole ball of wax! NMEA 1.5 is now 2.0! <<< 1. Connect NMEA+ from the plotter to NMEA in (blue cable) on the VHF. 2. Connect NMEA- from the plotter to the NMEA in on the VFH via an 8k Ohm resistor ($1 part at the closest Electronic part store / Radio shack etc). 3. Isolate the NMEA ground (green cable) from the VHF and leave it disconnected. 4. On the "NMEA out" menu option in the RL70, select RMC (you can de-select the other options if you don't have another NMEA consumer. That's it. Your GX2100 will now be able to read the <http://www.sailnet.com/forums/autolink.php?id=1&script=showthread&forumid=1 04> GPS location from your plotter!>>>> Once again, as everyone says, this list is the best. If no one has the answer, by gawry someone will go find it! Thanks again to Steve, and of course everyone else who chimed it with their suggestions.

I will be stopping off at Radio Shack this evening. I had searched through there, but I never found that particular post, good find. Whoops, no, I searched cruisers forums, not sailnet. The NMEA voltage bounces as high, I think, (bad memory) 6 or 7 V, and everyone I talked to said highs of 4 or 5, so, maybe cutting it will help. And Fred, I did try connecting with either the shield or the ground, but I will screw around with this some more before trying the resistor. You know what they say about the definition of insanity. . . Then when nothing works I will give up and buy another GPS antenna!

The 1.xx versions are single ended, signal and ground, while the 2.xx and later have differential + and - signal wires and should have a separate ground/shield. Funny thing is that the GX2150 does not have differential inputs. Anyway here is what one guy did to interface an RL series plotter to a GX2100. Might be worth a try. http://www.sailnet.com/forums/electronics/82335-how-connect-standard-horizon -gx2100-ais-vhf-raymarine-rl-70c-plotter.html Steve Thomas C&C27 MKIII Port Stanley, ON -----Original Message----- From: cnc-list-boun...@cnc-list.com [mailto:cnc-list-boun...@cnc-list.com]On Behalf Of Frederick G Street Sent: Friday, September 21, 2012 11:50 AM To: cnc-list@cnc-list.com Subject: Re: Stus-List NMEA 0183 Ver.1.5 to 3.0 Bill take a look at this PDF, starting with page 9: http://www.actisense.com/Downloads/TechTalk/NMEA%200183/The%20NMEA%200183%20 Information%20Sheet.pdf This might help. In my experience, sometimes there are issues with what gets labeled "input" vs. "output", as well as data + and - or ground; but be really careful what you try so you don't damage things. Usually it's just as easy as connecting the properly labeled leads together to get the signal to the proper place -- the problem comes in getting the settings right on the send and receive end, so that everything's happy.

The only thing I can adjust in the setup is turning sentences on and off, and the seatalk bridge. I have tried connecting them, no response. The sentences are coming in, the voltage rolls up and down. I think there must be something different in the protocol between 1.5 and 2. The Standard Horizon manual definitely says it will only work with ver. 2.0 and up. I have bridged NMEA to Seatalk as that is how the Autopilot communicates, but I don't think this would be a problem, that just introduces other info such as the compass and converts to NMEA, I think. A talk with a Standard Horizon Tech produced nothing, oddly enough he didn't seem to know much about NEMA conversions. Waiting to hear back from Brookhouse.
