Default Garmin Network PIN Outs ?

Anyone have a diagram of the Garming Network PIN outs for their RJ45 network connectors ? They do not appear to be standard 100BASE T pin outs...

Sure they are, they are standard straight thru.... so for example if yellow is on the right side of the connector on one end, it will be on the left side of the connector on the other end.

Which pin any color goes to makes no differeence, as long as the other side is an exact mirror of it (which means the wires go straight thru).

It would look like this (I picked random colors):

One end: Other end:

P1=yellow----P8=yellow
P2=Blue-------P7=Blue
P3=Green----P6=Green
P4=Black------P5=Black
P5=Grey-------P4=Grey
P6=orange---P3=orange
P7=pink--------P2=pink
P8=white-----P1=white

sorry to say, but thats not a standard straight thru cable pinout.

pin 1 would connect to pin 1, 2 to 2, 3 to 3, and so on.

a crossover cable would have pins 1 and 3 flipped, and pins 2 and 6 flipped. the rest of the colors would remain the same.

Duct,
On RJ45 or RJ11 type flat cables, that is a "straight thru cable. There really are no "pin #'s" on flat cables. It is ussually looked at a right to left. And since one end of the cable is flipped over since it's on the other end of a cable layed out flat on a table, it is referred to as a "straight thru".

When 1 and 2 goes to 2, and 3, Or 2 and 3 are swapped or similar, those are not straight thru as a cross over cable is.

Birdman,

Are you saying that Garmin uses flat cables for their networking? I havent done a garmin networked system, but i have never seen an ethernet based network that used flat wire. i have seen 8 conductor flat cable, but havent seen it used in a networked system of any kind.

Correct. And there are "Pin #s" for network cables. EIA/TIA 568A and 586B are the applicable standards, which specify wiring insulation color and terminal assignments to each respective circuit. I highly recommend following the standards in case a professional is called in for troubleshooting, and to make it easier for those that may purchase the boat at some later point in time.

Well, I don't recall at the moment if the actual cable itself is physcally "flat", it might be rounded cable. But RJ45 connectors are flat cable connectors, but you can easily install round cables into them, you just have to flat the wires out when you insert them to crimp. the Garmn network cable is a twisted pair cable, so it is probably rounded. Garmin provides a nice water tight sealing connector to attach to the end of the RJ45 connector. You slide it on before you crimp it, and it slides back down over the connection and screws to whatever you plug it into (display, radar....) which has the male threading on it ready to accept it.

But what I mean by "flat cable" is, think of it as a phone wire, or the old style grey flat cat5 wire. If you lay it flat, the wires goes straight from one side to the other side. No swaps, no flips, no.... just like in my above high tech color diagram!!

your pinouts would only make sense if using flat wire. otherwise you would want to wire them as shown in the link i provided. i've built hundreds of ethernet cables using crimp on RJ45s, and i have never used flat cable for networking. I dont think you are supposed to use flat, since its not twisted pair and wont reject noise.

Std Ethernet pin outs do not work. I've already established that :-) Just trying to find out what works for Garmin. I'll break down and reverse engineer one of the short Garmin cables if I have to, but I think Birdman has the right pin outs...

Thanks

if you already had a cable, why not just copy the pinouts when making a longer cable? is it a crossover cable?

The colors are not evident. I'll have to rip one apart to copy it. I may have to do that anyway just to make sure...

Garmin uses standard Cat5 8 conductor twisted pair cable, wired as a crossover cable as shown in the link provided by Duct Tape above.

Crossover, You can use a crossover cable from Staples for a while. I have done this in the cabin till I got the Garmin wire.
