I purchased two connectors. Two positive inputs on one are marked "+", but the combined single output is marked "-". The same is true of the negative...two negative inputs but the combined single output is marked "+". Is there something I don't know...

Depending on how many panels your connecting there are options 12 or 24 volt this is a link to the Renogy downloads with several schematics for different configurations. This link goes to the 2 panel setup using connectors http://renogy.com/wp-content/uploads/2013/12/200W-1x2.pdf. The next link takes you to the downloads page where you will find the configurations. http://renogy.com/renogy-solar/products/downloads/ Hope it helps.

beau. this one here has two ports. one @ 2.1a and another @ 1a. i dont think this combines both porta for a total of 3.1a.

That never seem to present as a problem. The 4 wires represent 2 pair (+,-) for left and right channels, and I just wired it to the same external speakers in parallel I have with my sound system. I have found the same result if I had wired an amplified subwoofer to my outputs either through the dedicated subwoofer channels, or tap into the speakers themselves.

I used the one labeled "pwr in" AND has the Positive (+) and Negative (-) symbols

There are two "jump cables". One negative (black) and one positive (red). They are neatly wrapped around the back of the unit. This is a very good product!!

Sorry to hear that, I only purchase 1 and it works fine. I am not sure if this help.

The Positive lead is clearly marked if you have the one with the rubber MC3 connectors, The Female MC3 (the one with the hole inside if looking at the face of the connector) is the Positive Wire. If you look at the rubber boot it has a + molded into it

Not at the same time time (it's a single output supply). But it is a "floating" supply. By connecting the red output to another supply's ground or common , the green output will be "negative" relative to the common connection.

I don't have the unit with me, so can't test to find out for you - I've not tried two inputs at same time. Both come with the unit.

If you mean where two wires are switched between corresponding pins, from one end to the other, I believe it will show an error on those wires. It appears it only shows good if you are 1 to 1, 2 to 2, etc. I made up network cables through my house and one would not work. Borrowed one of these testers from a friend and discovered that I had two wires swapped. Fixed it and ordered myself a unit that day. The coax ends are BNC so I bought two BNC to F, and BNC to RCA, adapters. Great unit for the price.

Usually you use the two outside terminals or whichever ones are marked + and -. Polarity does not seem to matter to the charger.

I know it says "input" on 2 and "output" on 1 connector. But, you can really use it either way. 1 input to 2 outputs or 2 inputs to 1 output. It's possible that there is some signal degradation, but I've used it successfully to switch between two outputs. Most of the time you wouldn't need to do that, as a splitter provides 2 outputs for 1 input. In the past, I had to use this switch instead of the splitter, because I wanted to have a bit of isolation. It worked fine.

Yeah. There's one wire for a positive signal and one wire for a negative signal attached to each other.

When facing the front of the meter, the port on the left is negative (-) while the port on the right is positive (+). In other words, if you apply a positive pressure to the left port the reading is negative and if you apply a positive pressure to the right port the reading is positive.

Good question Rick...although I am not tech savvy I will say that there is a port in the side that has a three prong symbol if that means anything to you...sorry I could not be any more help to you.

That depends on the input voltage/amperage and polarity of your speakers. On the back there should be a label with what looks like a little circle with a line coming out of it in another circle. Where're the + and - signs? There should also be a thing that says INPUT: ___ V or mV, ___A. What numbers are by the V and A? However, my kneejerk reaction would be to say no because as soon as I plugged in the adapter I bought it started sparking and immediately stopped working.

the common is for your input voltage you want to use for the output(no/nc). Your neutral or negative would go to the device you are controlling. The output(no/nc) would then go to the hot or positive of the device you are controlling.
