router hookup

[Xplicitlnck]

Im Installing the router (linksys) to my fusion. Ip700 this weekend. I made sure the router I purchased was 12v it actually says its 5. Well anyway how would I hook this up so it powered by the 12v system. Simply cut the 110 plug off and wire it to a power source with a fuse? (What amp fuse should I use) should I cut before or after the 110 to 12v converter or is the converter Internal? Kinda lost on this one?? The router is strickly only for the radio to my ipad nothing else

if the sticker on the router says 5 volt - it is a 5 volt unit. Connecting it to 12-14 volt would fry it right away. While it might work for a little while - the 5 v power regulator is not designed to dissipate the heat from regulating from 12v to 5v. It will get very very hot - and burn out. If it is a 5 volt router - you need a 12->5v converter. I would find a regulated converter but that might cost as much as the router did.

Fuses - well look at the power supply. That has a max Amp out. Chose a fuse size close to that if you can find it. The power sticker on the router might also have a max amp draw figure on it. Again chose a fuse that is slightly larger.

If you don't want any issues - get a MikroTik router. For $40-$60 you can get a router with much better performance - and input volt range usually from 8-30 volt. If you get one with USB you are free to plug in a 3G USB modem for "internet" access.

Thank you very much

I stand corrected. I did a little more research on the linksys router. It will Handle a voltage input from 3-40volts and then an internal voltage regulator regulates down to a constand 3.3volts. Therefor I feel I am safe cutting th 110plug off. Installing an inline fuse on the positive. And wiring to a 12v source. Am i correct?

Thanks everybody rea lly appreciate the help

I have never heard of a Linksys with a wide voltage range. But please educate me - which model is it?

im no expert either, but ide imagine you will cut out the transformer on the cord (no need to convert ac to dc anymore) then wire it directly to a battery (with a fuse) Im thinkin about doing this same thing so I can use Simrad Gofree App

Heres a youtube vid i found that is pretty much the same concept...

Alright, so I got home and gave it a whirl tonight. Since I work for the local ISP I have like 100 old gateway/routers in my work van... I cut off the transformer plug so I was left with just the skinny cord. I stripped it back and tied it down to my marine battery... Poof! fried it immediately!! no biggie, grabbed another one and reversed positive and neg and plugged it in. It turned right on and worked perfectly! So, in conclusion it will work just make sure you got the correct polarity... ps these were Actiontec routers that said 12-15VDC

Ha thats great. Thanks for doing the test work. So the next question would be how do I figure out witch wire is ground witch is pos?

On mine, the wire with a white stripe (barely noticeable) was the positive, otherwise to be safe, you could use a multimeter, the inside of the jack will be pos the outside ring is neg

Your talking to somebody that used a multimeter once and had very specific directions on how to use it. When it comes to wires and electrical you need to speak to me like im 5 lol.

HEHE.....im not sure what the jack on the end of your cord looks like but ide imagine its round with a hole in the middle (I don't know how else to describe it lol) If it is.... set the MM to the OHMS setting, stick one probe from the MM into the center hole of the jack, then probe each wire on the other side... the wire that reads 0 is your pos.....ORRRR you could probe the outside of the jack and that would be your neg
