Remote hub for temp and float switches

[cosmith71]

I'm thinking about relocating my RA from the stand to a cabinet located next to the tank. I'd like to make a little hub to place under the stand so I can plug/unplug the temp probes and the float switches there instead of having to follow cables back and forth from the stand to the cabinet.

I was thinking of having a breakout box with the following lines from the RA (thinking ethernet cable):

Ground (from one of the float switch ports or temp ports)
+5v from a temp port
ATOLow+
ATOHigh+
Signal line from a temp port

On the breakout box, I'd have a jack for ATOLow, ATOHigh (ATO lines and the ground) and 3 jacks for temp probes connected to ground, +5v, and temp signal.

Any obvious problems with this setup?

You should be fine

Oh, and a pH extension, too. I'll probably just use a BNC extension cable for that.

So I got this done. I basically glued some 3 pin and 2 pin connectors (jumper wires, really) together. It works, but it's ugly and one of the 2 pin connectors broke almost immediately. I found this on Amazon for version 2.0.

I think I'll mount it to a small PCB with sturdier 2 pin connectors. May use pieces of header strip.

Nice job

[cosmith71]

Thanks!

Very Nice! Does that eliminate any "stress" on the sensor Bus? Any chance you are going to get with Roberto/some other smart guy and make a RANet version?

Also, is the knob on your RA Broken? It looks off center in the picture. Again, nice job on that.

[cosmith71]

It's not broken, just the angle of the picture I suppose.

It's only purpose is to simplify the wires going from under my tank to the cabinet beside my tank where the RA is. It's extremely simple.
