Re: Stus-List NMEA 0183 vs. 2000 Wiring Compatibility
Old cable generally makes a decent pull string :) ...assuming they're not fastened in some inaccessible location. I'm surprised at the current ratings for that 15ga wire, given how long the run could be, although I suspect most N2K busses carry much less than the maximum; otherwise the voltage drop would be significant. -- Shawn Wright shawngwri...@gmail.com S/V Callisto, 1974 C&C 35 https://www.facebook.com/SVCallisto On Mon, Apr 27, 2020 at 1:47 PM Bill Coleman via CnC-List < cnc-list@cnc-list.com> wrote: > To Josh’s comment, I didn’t think of the backbone being more robust, that > makes perfect sense.

Re: Stus-List NMEA 0183 vs. 2000 Wiring Compatibility
To Joshs comment, I didnt think of the backbone being more robust, that makes perfect sense. And it turns out it is, according to Maretrons data. I got this off Maretron site for cable, 2x15 (1.45mm) AWG 3.44 Ohms/1000 ft max 16 Amps NB1 14 Amps NG1 Red/Black 2x18 (1.02mm) AWG 120 Ohms ± 10% 12 pF/1000 ft Max White/Blue So it looks like the power cable is 15 Gauge and the data is lighter at 18 Gauge. So I guess I better make sure I have at least 15 Gauge wire or else try and get another wire through some difficult spaces. And Jim, I may have miss-spoke, when I said the wire was twisted, I should have said they (Power, red and black) were twisted strands inside the insulation, they are actually not twisted around each other. Thanks all for all the input.

Often when you are replacing 0183 devices with newer N2K devices, the older devices already had power run to them. Using a short N2K pigtail cable, you can splice the signal cable to your existing 0183 network cabling and the power cables to your existing power. Or use a power injector close to the new device. The idea of NMEA 2000 (N2K) was that a single cable would run through the boat and there would be short connections (drops) to the main cable to connect the various devices. Think of it as a set of icicle Christmas lights. The main cable carries the power and the short drops connect that power to the lights themselves. NMEA 0183 was typically wired in one of two methods, home runs or daisy chains. Depends on the installer. Home runs are where all the devices were wired back to one central location and would require that you to use something like Maretron's multiport box to interconnect your devices. This makes for some long wire runs to various devices and could possibly cause intercommunication issues between devices that are separated by the most amount of wire. Shouldn't, but could. If your boat was wired in a daisy chain, you would just need to replace the connectors where the cabling went into and out of the old device and add a T-connector to provide your drop to your device. This wiring method would more closely represent the main backbone system used by N2K, except your backbone runs everywhere in the boat instead of just down the middle. While trying to reuse the existing wiring may save you some expense in the wire costs, typically there is an easy wiring route for a new main run through the bilges or behind the settees. Then you just have to run the short drops through somewhat more difficult areas. About the most difficult one I can think of would be getting up the walls and through the ceiling to the place that the wires enter the mast. All the remaining runs should be fairly easy. My personal opinion is that while doing things to make the existing wire work can be done, it isn't worth the headache and expense that you would encounter down the road when a connection that wasn't done perfectly causes problems for the whole system. Also, manufactures don't tend to warranty things that are not done to spec. So if you are purchasing new equipment, best to go with the correct wiring also.

Re: Stus-List NMEA 0183 vs. 2000 Wiring Compatibility
I’m going to presume the power wires are twisted in order to minimize any electromagnetic fields developing that would cause a noise signal that the instrument wires would be vulnerable to and would interfere with signals therefore giving erroneous readings. The signal wires probably don’t carry enough current to cause any interference.

Re: Stus-List NMEA 0183 vs. 2000 Wiring Compatibility
I think the spec on the power is similar to USB. It should be limited to about 500 milli amps. I guess I could check the power tee portion for a rating. The other question I would ask you Bill is, did you check a section of cable that is supposed to be used for backbone?

Re: Stus-List NMEA 0183 vs. 2000 Wiring Compatibility
Since the NMEA2K conductors usually run from the top of the mast to the back of the boat and supply power to all the devices in between, the voltage drop is a significant problem even if you use the recommended cables. Using the NMEA 0183 cable which doesn't usually supply power to all the devices along the way will probably not be acceptable, especially since they're probably won't be enough conductors anyway. I recommend you go with the recommended cables and also make very sure that the wires supplying the network backbone are sufficient to prevent significant voltage drop.

Yes there is a spec for N2K wiring and it differs from 0184, however for relatively short runs (or for that matter even the longer ones) you'll probably be OK. The biggest thing you'll want to verify is that the gauge of the conductors is matched for the power wires. In N2K you'll find a red and black wire that are typically larger than the signal wires. Those red and black wires supply power to all of the downstream devices. One device is probably not a big concern... Multiple devices - might make a difference. So if it is a branch you'll likely not have a problem, if it is a section of the backbone it might cause trouble. Other than that, it is certainly worth a try.

Re: Stus-List NMEA 0183 vs. 2000 Wiring Compatibility
Generally need 5 wires of adequate gauge to handle powering the downstream devices - if required. You can buy connectors to attach yourself to the cable ends. You might have some electrical interference issues but the bus can handle some transmission errors.

Stus-List NMEA 0183 vs. 2000 Wiring Compatibility
I am replacing some 0183 wiring for NMEA 2000, and I bought some 2000 end connectors (Maretron FA-NF-ST Mini Field Attachable Connector (Female) FA-NM-ST) that you can screw the terminals into. Some of this 0183 wiring was probably installed before the boat was completed, and It looks very difficult to re-wire. Does anyone know if I can just use the 0183 wiring to now become 2000 compatible? In other words, is there anything lacking in the older wiring, like shielding, twisting, etc, that would make this not work?
