IW3702 cable pinout

[Vyacheslav_Maliev]

Need help to make cable RJ45-M12 for IW3702 access points the same as included but more than 10ft long. I found pinouts for PoE-IN port in documentation guide but don`t understand from this table how to use it. Would like to have pair numbers and colors for standart B before order this cables.

Please help me understand this table from thr doc above:

1	0_P signal	5	3_P
2	0_N signal	6	3_N
3	1_P signal	7	2_N
4	1_N signal	8	2_P

what colors and pair numbers should i use for standart B RJ-45?

Not 100% sure, as I never used such a cable, but I guess it's the following.

Pin 1+2 are twisted pair 0 positive and negative

Pin 3+4 are twisted pair 1 positive and negative

and so on.

Also check this nice picture I've found (which sadly shows another PIN layout as the table):

But honestly, I'd trust this image.

Still don`t understand how to provide the correct pinout scheme, here we have pinout from standard T568B

what pin/pair numbers from the table are match to the picture?

[patoberli]

The numbers on my image are the pin numbers on the plug.

So in the case of the blue pair, the half blue goes to RJ45 pin 5 and on the M12 to pin 7. The full blue goes on RJ45 pin 4 and on the M12 pin 8.

Check the Cisco image for the pin numbering on the M12 which I posted way earlier.

[Vyacheslav_Maliev]

yes, you`re right for example from image, but then it doesn`t match for the table from official docs because pin 78 on the m12 belongs to pair #2.

[patoberli]

It probably won't matter, as long as the pin configuration is correct. I suggest to make a cable and test it. If one pin is wrong, it probably won't work at all.
