RJ-45 junctions, 3 female connectors

[Qmavam]

Hi guys,
I got an email from MPJA and they have a cat 5 rack with 48 in/96 out RJ-45 connectors.
The connectors are removable from the rack.
I hope this is useful to make a multi drop 1 Wire system.
I hope to use the connectors as a feed thru with a tap. About $0.65 per splitter.
Thought someone else might be interested.

Sorry Guys,
I've done some continuity checks and the part is not as I had thought.
Here is the pinout.
There is no connection from input A to input B.
The connections from C to A and C to B are below.
Input---Input------Input---Input
----C --- A-------------C --- B
Pin 3 to 3 ------------ 1 to 3
Pin 6 to 6 ------------ 2 to 6
Pin 7 to 7 ------------ 4 to 7
Pin 8 to 8 -------------5 to 8
I'm looking at adding jumpers inside the splitters.

Ok, I have added jumpers inside the splitters, not a bad job. Connector comes apart easy (at least the second one does I put two jumpers
on one side of the pcb, turned it over and add two more on the other side. I used wire wrap wire.
So I have two pairs wired in the connectors.
I was a little disappointed when I found the DS9097 had a 6 pin connector. I had make another trip
to Lowes and spend $6 for a box of connectors, when I only needed one.
I have a circuit with 4 splitters and 5 sensors set up and working (about 50 ft using onewireviewer).
I still haven't got the Lampomittari software to work for me, but I hope to visit my computer guru this week and get help.

Mike, do you have pictures of the inside, after your jumpers? What is the pinout now?

Thanks,
Rob

I didn't take any pictures, maybe next time I modify a group I'll get pictures.
I used pins 7 and 8 for one pair and 6 and 3 for the other pair.

I used two knives to open splitter case, Be Careful!!



Here's the case opened.



I'm out of attachment space, see next post.

This is with pcb separated from case, I pulled the pcb out with a pair of needlenose pliers.
For some reason this one was particularly difficult, thus the scratches on the pcb.



This shows the jumpers on one side. If your attempting this, note the orientation of pcb.



Then I turned the pcb over and put two more jumpers on the otherside.



Then put the case back together and your good.
I always check continuity before I reassemble.
Pin 7 and pin 8 is one pair, pin 6 and pin 3 is the other.

I know this is an old post and all.. but I was curious if this device would work:

It sounds like it would from reading this post, but i wanted to ask..
