What is the S-video and PS/2 port?

S-video (short for Super-video) is an older type of video signal that’s transmitted in varying electrical signals over wires to represent the original video. Newer video cables like HDMI transmit digital video signals in the form of numbers representing the original video signal. The benefit of digital video is that the signal doesn’t degrade from source to destination. It’s also capable of transmitting much higher resolution video.

S-video is an improvement over composite video, which carries all the video data (including both brightness and color information) in one signal over one wire. S-video carries brightness and color information as two separate signals, over two wires. Because of this separation, video transferred by S-video is higher quality than that of composite video.

The S-video cable transmits video through two synchronized signal and ground pairs, named Y and C. S-Video (4-pin)

PS/2 port

The PS/2 (Personal System/2) port, also referred to as the mouse port or keyboard port, was developed by IBM. It is used to connect a computer mouse or keyboard to an IBM compatible computer. The PS/2 port is a mini DIN plug that contains six pins and is still sometimes found on all IBM compatible computers.

About XLR Pinout (3-Pin, 5-Pin & 7-Pin)

图片
  About XLR Pinout (3-Pin, 5-Pin & 7-Pin) XLR connectors are used in audio (mic level & line level) and DMX lighting control (DMX) applications.                              3-Pin XLR and 7-Pin XLR Audio Pinout The following is the AES industry standard for balanced audio XLR wiring, commonly known as “pin-2 hot”. 3-Pin XLR connectors are standard amongst line level and mic level audio applications . The above diagram shows you the pin numbering for both Male and Female XLR connectors. 3-pin XLR Pinout: Pin1 = Shielding (Ground) Pin2 = Hot (Positive), + Pin3 = Cold (Negative), – 7-pin XLR Pinout: Pin1 = B+ Pin2 = Pattern Pin3 = 6 Volts Pin4 = Gnd Pin5 = Out Pin6 = Out Pin7 = Gnd                     3-Pin XLR and 5-Pin XLR DMX Lighting Pinout The ESTA standard known as Entertainment Technology USITT DMX512-A – Asynchronous Serial Digital...

What is 5 pin DIN connector?

  What is 5 pin DIN connector? A DIN connector is an electrical connector that was originally standardized in the early 1970s by the Deutsches Institut für Normung (DIN), the German national standards organization. A DIN connector encompasses several types of cables that plug into an interface to connect devices. It has an architecture that is composed of multiple pins that are within a protective circular sheath. Typically, a full-sized DIN connector has three to 14 pins with a diameter of 13.2 millimeters. In computer electronics, the DIN connector is referred to as a circular connector that is DIN standardized and used for digital interfaces like the musical instrument digital interface (MIDI), the IBM AT computer keyboard or mouse, and in analog video architectures. Original DIN standards for older connectors are no longer in print and have been supplanted with the corresponding international standard IEC 60130-9. There are seven familiar patterns with three to e...

How to choose the right speaker wire/cable?

  How to choose the right speaker wire/cable? The purpose of Speaker cable is the wire used for the electrical connections between amplifier sources and loundspeakers system.The transfer is accomplished through the low-voltage electrical current conducted through the wires.It has three key electrical properties: resistance, capacitance and inductance. Resistance is by far the most important property to look at. Today most loudspeaker systems have an impedance between 4 ohm and 8 ohm. As the resistance rises it starts to affect the system performance. Obviously there can be a reduction in the drive current to the loudspeaker as the voltage across the cable increases. The other issue is that the back EMF created by the loudspeaker needs to have a low impedance source against which to work. As the source impedance rises, so the back EMF is absorbed less. This affects the performance of the loudspeaker, particularly in the bass region where the bass may not be as pronoun...
