General question about jumpers

[Guest]

Archived from groups: alt.comp.periphs.mainboard.asus (More info?)

I have a very general question about jumpers. In the handbook of my A7N8X-X
every PIN is described exactly. For example, for the speaker connector it
exactly says which PIN is +5V, which ones are Ground and which one is
Speaker. However, on the 4-PIN connector cable one this information is not
given. Does is _not_ make any difference which way I connect the cable;
after all, there are two possibilities? If the way I connect the cable _is_
important, how do I know how to do it (except for trial and error)?

Thanks,
Matthias

Can I point out to you that when you connect a cable to the motherboard, you
are connecting a cable to a motherboard header. Jumpers are used to short
two (or more) pins together. Yes, the connectors are similar, but the whole
idea is different.

Technically directional, but practically either way will be fine.

Directional, since it's a Diode.

Both momentary switches... either direction is fine it's the (short)
connection you're looking for.

Again, and LED (diode) and thus directional. If you plug a diode in the
wrong way around, it won't work. You won't break it by doing this, it's
completely safe to try a hit and miss approach. (connecting the wrong pins
together is a completely different thing altogether and could break things).

Maybe. But cables connected the wrong way around is unlikely to cause you
stability problems.

I would suggest checking your temperatures, if they are ok, replace your PSU
with a better one.

Thats ridiculous. Thats like saying my speakers sound better when I use the
wires the other way round. It might be true, but it will not be a direct
result of turning the jumper around, it will be an indirect result of
correcting a bad connection either on the jumper or something else.

Or... my stereo speakers sound better when I listen to the right speaker
with my left ear and the left speaker with my right ear

I can confirm that this jumper is very uncomfortable, and looks silly,
when I turn it round.
