Jumpers manually configure computer peripherals, such as the motherboard, hard drives, modems, sound cards, and other components. For example, if your motherboard supports intrusion detection, a jumper can be set to enable or disable this feature.
Before plug and play, jumpers were used to adjust device resources, such as changing what IRQ the device uses. Today, most users don't need to adjust jumpers on their motherboard or expansion cards. Usually, you are most likely to encounter jumpers when installing a new drive, such as a hard drive. As shown in the picture, ATA hard drives have jumpers with three sets of two pins. Moving a jumper between two pins changes the drive from primary drive, secondary drive, or cable select.
Some documentation may refer to setting the jumpers to on, off, closed, or open. When a jumper is on or covers at least two pins, it's a closed jumper. When a jumper is off, covering only one pin or the pins have no jumper, it's an open jumper.
While jumper wires are easy and inexpensive to purchase, it can also be a fun task to challenge students to make their own. Doing so requires insulated wire and wire strippers. However, beware that it is important not to nick the wire when stripping off the insulation.
Alligator clips, which consist of two spring metal clips connected by wire, are actually just fancy jumper wires! Their unique connection point (they can be clipped on instead of inserted into) allow alligator clips to be used in a variety of situations that would get a little awkward with a traditional jumper wire. One of the most common uses for alligator clips in education is with the Makey Makey, though they can also be used to connect the ports on a LilyPad board as well as for a number of other applications.
The layer on top of the copper foil is called the soldermask layer. This layer gives the PCB its green (or, at SparkFun, red) color. It is overlaid onto the copper layer to insulate the copper traces from accidental contact with other metal, solder, or conductive bits. This layer helps the user to solder to the correct places and prevent solder jumpers.
The breadboard is divided into a main area in which you build your circuit surrounded by a smaller power bus section with the buses organized in horizontal rows. There are also horizontal slots in the main section designed for integrated circuits. Cut pieces of twenty-two gauge solid insulated wire into at least thirty jumper wires of lengths between two and ten inches, stripping roughly half an inch of insulation from both ends of each jumper wire.
Make sure the adjustable DC power supply is off and then insert one end of a pair of banana cables in the positive (red) and ground (black) connectors of the breadboard and insert the other end of the banana cables in the appropriate banana binding post jacks. Place a three or four inch length of jumper wire in the small horizontal hole of each binding post, tighten both posts, and insert the other end of each wire in a separate power bus row.
Insert the other components into the breadboard holes while observing the row-column connection scheme. If you run out of holes in a column simply insert a jumper wire between that column and an unused column for additional connections. After that use jumper wires to connect the power bus holes and sections of the circuit requiring DC power and ground. If the circuit has outputs, insert lengthier jumper wires in the outputs and connect them to the appropriate external equipment.
Handling PCB jumper pads and traces is an essential skill. In this tutorial, you will learn how to cut a PCB trace and add a solder jumper between pads to reroute connections. You will also learn how to repair a trace with the green wire method if a trace is damaged.
However, that may not always be the case for jumpers. Standard 0.1\" pitched pins can have a wider gap or a development board may have a pin located in a different position. Additional solder, 2-pin jumper blocks, and jumper wires may be required to make a connection.
If you decide to set the FTDI back to its default of 5V, simply heat the intentional solder jumper with a soldering iron and move the solder back to the right side. Feel free to add more solder if necessary.
Before you can add a jumper, the conductive surfaces must be exposed at the point of the break. You can use the cutting tool to carefully scrape away at least 3mm length of the overcoat material. A rotary tool grinding bit, held in your hand, is a good tool to gently scrape away resist in a controlled way. Make sure to scrape lightly to avoid damaging the conductive material of the trace underneath.
The minimum sizes of the grounded conductor, EGC and GEC are determined based on NEC Table 250.102(C)(1), Table 250.122 and Table 250.66, respectively. The sizes for the main bonding jumpers, supply side bonding jumpers and system bonding jumpers can also be sized from Table 250.102(C)(1).
The grounded conductor at the service should be sized in accordance with Table 250.102(C)(1), based on the size of largest ungrounded conductor or equivalent area for parallel conductors. This table can also be used to size the main bonding jumper, system bonding jumper and supply-side bonding jumper for AC systems. As stated in the notes of Table 250.102(C)(1), for ungrounded conductors larger than 1,100 kcmil copper or 1,750 kcmil aluminum, the conductor shall have an area not less than 12.5% of the area of the largest ungrounded supply conductor or equivalent area for parallel supply conductors. If the ungrounded conductors are installed in parallel in two or more sets, the grounded conductor shall also be installed in parallel.
Bonding jumper, supply side: A conductor installed on the supply side of a service or within a service equipment enclosure(s) or for a separately derived system that ensures the required electrical conductivity between metal parts required to be electrically connected.
Bonding jumper, system: The connection between the grounded circuit conductor and the supply-side bonding jumper or the equipment grounding conductor or both, at a separately derived system.
How did I go from being an A-circuit hunter/jumper trainer, showing, riding, teaching, running my own business and traveling the country, to becoming the co-founder and director of a miniature donkey rescue
We began to educate ourselves about horse rescue in general. Having spent my adult working life in the privileged world of the hunter/jumper industry, I am embarrassed to say that I had no idea the fate that awaits so many horses and donkeys in this country. Our research led us to the local auctions where horses are sold to dealers and buyers who have contracts with the slaughter plants in Canada and Mexico. Thousands of horses and donkeys are sold every week at auctions all over the country and a few thousand of those are shipped for slaughter. As a lifelong horseman, I was absolutely sickened by this.
A jumper is a tiny metal connector that is used to close or open part of an electrical circuit. It may be used as an alternative to a dual in-line package (DIP) switch. A jumper has two or more connecting points, which regulate an electrical circuit board.
A jumper is made of material that conducts electricity, and is sheathed in a nonconductive plastic block to prevent accidental circuit shorts. A jumper positioned over two or more pins creates a connection that activates certain setting instructions.
Jumpers are like on/off switches. They may be removed or added to enable component performance options. A group of jumper pins is a jumper block, which has at least one pair of contact points with a small metal pin at the end. A sleeve or shunt is draped over the pins to allow electric currents to pass over other circuit points.
Older PCs used jumpers to set voltage and central processing unit (CPU) speed. Moreover, jumpers and jumper blocks were used to reset basic input/output system (BIOS) configuration and clear complimentary metal oxide semiconductor (CMOS) information.
Older PCs contained at least one jumper and, in many cases, a bank of DIP switches. It was common to find 30 to 40 jumper pairs on a motherboard. Because of poor documentation, some systems were difficult to set correctly, and motherboards eventually had fewer labeled and numbered jumper blocks.
Grove Base Shield can play the role of breadboard while its plug-and-play design enables a more convenient using experience. Grove Base Shield provides a more simple way to connect with Arduino boards and helps you get rid of breadboard and jumper wires! You can directly connect grove sensors to the Base shield through Grove Cables.
Grove is a modular, standardized connector prototyping system. Grove takes a building block approach to assembling electronics. Compared to the jumper or solder-based system, it is easier to connect, experiment, build, and simplify the learning system.
Arduino Uno is the most popular Arduino board so far, however, it is sometimes frustrating when your project requires a lot of sensors or LEDs, and your jumper wires are in a mess. Base Shield provides a simple way to connect with Arduino boards and helps you get rid of breadboard and jumper wires. With the 16 on-board Grove Connectors, you can easily connect with over 300 Grove modules! Apart from the rich Grove connectors on the board, you can also see an RST button, a green LED to indicate power status. The pinout of Base Shield V2 is the same as Arduino Uno R3.
... but I had exactly the same error. I will note, that the alternate possibility from above for a closed version of the jumper of setting Spice_Netlist_Enabled to N did in fact work... but I don't consider it resolved, since it only works \"half way\".
You can use jumper wires to modify a circuit or diagnose problems in a circuit. Further, they are best used to bypass a part of the circuit that does not contain a resistor and is suspected to be bad. 153554b96e
