What is the use of jumper setting?

What is the use of jumper setting?

In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers. The process of setting a jumper is often called strapping.

What are SATA jumpers for?

On SATA-II drives, a jumper is sometimes used to set the drive into SATA-I mode for compatibility with older controllers.

Do IDE drives need jumpers?

For IDE hard drives, it’s important to properly set the jumpers. If not properly done, your computer may not boot or the hard drive won’t be detected.

How much slack should there be in jumper wires?

Thermal expansion and mechanical stress affect all components including jumper wires. Adding a bit of slack near the termination point is all that is needed. As an added note, you should avoid very tight bends in jumper wires. Avoid bending the jumper wire tighter than a radius of 3 times the conductor diameter.

How do Jumpers work?

When you set a jumper, you place a plug on the prongs that completes a contact. In effect, the jumper acts as a switch by closing (or opening) an electrical circuit. Jumpers can be added or removed to change the function or performance of a PC component. A group of jumpers is sometimes called a jumper block .

What is jumper used for?

In electronics and particularly computing, a jumper is a short length of conductor used to close, open or bypass part of an electronic circuit. They are typically used to set up or configure printed circuit boards, such as the motherboards of computers.

What voltage are jumper cables?

The biggest mainstream size of the jumper cable is 2 AWG. In this size, the cable can handle the maximum ampacity of 165 Amps at 35kV, which sets its approximate voltage at 35kV.

Where should you never use a jumper wire check?

Remember this one important rule – Never place a jumper wire across a load. Here’s why: If your place your jumper wire across a switch, all you are doing is closing a circuit that the switch would normally close and allowing current to flow through the circuit.
