Cords connecting to an RJ11 interface require a 6P2C connector. Nevertheless, cords sold as RJ11 often use 6P4C connectors (six position, four conductor) with four wires. Two of the six possible contact positions connect tip and ring, and the other two conductors are unused. RJ11 is commonly used to connect DSL modems to the customer line.
The 6P2C, 6P4C, and 6P6C modular connectors are probably best known for their use as RJ11, RJ14, and RJ25 non-powered registered jacks, respectively (and 6P4C and 6P6C for powered RJ11 and RJ14, power being delivered on the outer pairs). These interfaces use the same six-position modular connector body but have different numbers of pins installed.
A pointing stick on a mid-1990s-era Toshiba laptop. The two buttons below the keyboard act as a computer mouse: the top button is used for left-clicking while the bottom button is used for right-clicking. Optical pointing sticks are also used on some Ultrabook tablet hybrids, such as the Sony Duo 11, ThinkPad Tablet and Samsung Ativ Q.
The naming confusion section refers to RJ11 as "six-position" and then in the next sentence "The four-position RJ-11". The picture labels the four pin plug as "RJ11". What the picture labels "RJ11" is in fact a six position plug. And it has 4 pins. The two outermost slots in the plug don't have pins in them. Hence, this is a "6P4C modular plug."
In computing, a keyboard controller is a device that interfaces a keyboard to a computer. Its main function is to inform the computer when a key is pressed or released. When data from the keyboard arrives, the controller raises an interrupt (a keyboard interrupt ) to allow the CPU to handle the input.
The introduction of the Apple II was a major leap in development for Apple, as the product included a built-in keyboard (a first!), multi-color on-screen graphics, and more.
It used a telephone cord-style RJ-11 connector to the case (also used with the Amstrad PCW series of computers). The keyboard pinouts are "crossed" so it isn't possible to use a standard telephone cord as a replacement; doing so will result in damage to the keyboard or the computer. [ 15 ]
