I have a ranger 1860 angler and can't get the temp to read, it is that stupid NEMA hook up so everything goes to the infloor transducer, I am no rocket scientist but for the life of me cant get it configure to read the temp any input would be greatly appreciated. thanks.....

I'm guessing you're in the "overlay data" option menu and wish to place the water temp on one of your screens?

If you are, go into the list of things you can display, speed, depth, time, etc, etc, and go all the way to the bottom. Select sensor data or something along those lines. I don't recall the exact terminology, but it should be the EP-35 data I believe. This should be the temp sensor data you're looking for.. There is another temp option higher on the list but this is for the temperature sensor that is hard-wired to the sonar and not on the network.

Not sure if this is your problem or not, but thought I'd give it a shot. I have the same sensor in my 618T and noticed there are two temp sensor options in that overlay data list but only one is the right sensor.

Another option to see if the graph is even "talking" to the EP-35 sensor is to go to the option in one of the menus that lists the items that are connected to the NMEA network such as other graphs, GPS puck, or the EP-35 temp sensor. If it is on this list, then at least you know it's connected and talking to the 520.

Limit, I had it back at the dealer last fall and the gave me a "T" peice to connect but I don't know where to connect it to, I see the cord coming out to the graph connected and I get everything excpet for a temp reading, I don't mean o the graph itself, cause it just says 32Degs, I have that much showing on my over lay datat, jus doesn't read the actual temp so where is this "T" connection suppose to hook up to ???

I'm not following exactly how this is installed. Did you install the 520 with the water temp sensor, or was all of it done by the factory/dealer?

Even if it is flashing "32", the data on the screen may set to the hardwired temp sensor that you don't have. The graph is set to that by default and it needs to be changed to the EP-35 sensor which is the one mounted in the hull. If that "32" is indeed the EP-35 sensor then we'll have to figure out the existing network.

So, if the overlay data is truly the EP-35 sensor look to see where the network cable goes to that leaves the 520. I'm just guessing that they put the network backbone under the dash? Wherever it is, you'll probably see more of these "T"s. What color connectors are on the existing T's and on the one they gave you (red or blue?). Hopefully they're all the same color to make it easy.

Just think of these "T"s as a network hub for a computer. You plug in all your devices into the "T"s or backbone and then one cable should connect to the graph. So you could potentially have a T for the graph, one for a GPS puck, one for the transducer, and one for this EP-35 temp sensor. If you have more than one graph there will be a T for that to connect to also.

The T's should line up side-by-side and connect to one another. Off the top or bottom (depending on how they were mounted) is where the cables go to all these devices scattered around the boat. I'm betting that on the last T there is a thing that looks like a cap or plug screwed onto the left or right "arm" of the T. This is a terminating resistor for the network. Unscrew that, insert the T the dealer gave you by connecting it to where that resistor once was, and then put the resistor on the opposite end/arm of that new T. Plug the EP-35 temp sensor on the top of the new T and you're done with the wiring.

This problem sounded familiar so I went back in the archives and saw that you had some issues with this last summer. In those threads you had mentioned that you had broken a T when you were trying to get the GPS working, and I'm assuming that was the T for this temp sensor. You should be able to replace that T with this new T and be good to go.

yep that is me, I will try the EP deal tomorrow when I awake, then get back to you, hopefull that will be it, if I get the ep done will it get near the air temp, so I don't have to take it to the water to see if it is working... Thanks.

Hey Limit I spent about an hour in the boat in the garage today playing with the graph and still can't figure it out I didn't see any EP-35 on any of the screens, maybe you could lead me through it step by step, from the time we turn the thing on, thanks...

Also I have the temp on the screen it just keeps flashing 32 degs, and it does that on any screen I go to, don't know if that helps explain my situation or not. thanks again.

Hit the Menu button twice and scroll down to NMEA 2000, hit enter and then select Bus Setup and then enter again. Look to see what devices are listed. Do you see EP-35? If not, then you need to replace that 'T' or figure out what is wrong with the wiring/network. If the GPS is working then the fuse should be good.

Gps works, graph works for depth and all, just can't get the [PoorWordUsage] temp reading to work, I will try what you said tomorrow and get back to you, thanks for all your help, it was all a lot easier just hooking the transducer to the back instead of all this nmea stuff. Would you think if all the other stuff works that I wouldn't even need that "T" and maybe just the EP_35 deal. I hope it works it is driving me nuts.....

Limit I searched, I can't find a cord that connects to the temp under my dash, I would have to think that they didn't run it all the way, I looked in the back of the boat and see a couple of different cords that connect to the hull of the boat, but I think only one makes it to the graph, I may have to take the side panel off and see where the other stops, or maybe just take it back and have them deal with it, but a 3 hour trip is a long way just for that. Thanks for the help.

Did you see the other T's? In your thread last year you mentioned you damaged one of the T's. Did you replace that one and did you figure out what device is connected to that damaged T? How many T's did you find? On the ends of the string of T's, what was connected? Let's say you had three T's connected end to end, what was on the far left of the 1st T and what was on the far right of the 3rd T?

Right now I only have the two t's hooked up, on the one end there is a gray cap, on the other it is open off both t's I followed the cables, on goes to the graph for power, the other is for the transducer, these are all blue in color, then there is a red one that hooks directly from the graph to the gps puck and that is a maroon color. and if you can follow this you are good. I am lost looking at all that stuff, any advice....

Hey limit, when I open the back compartment and look down on the fiberglass hull, I see two different type transducers, one is on the very bottom, I believe that is the graph, the other is on the next level, I think that may be the temp sensor, is that how yours is on you glass boat??? am I on the right trail here. I have to follow both of those and get them hooked into the graph?
