FTDI US232R : USB to RS-232 cable. A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232, RS-485, RS-422, or TTL-level UART serial data.
The USB 3.0 Micro-B plug effectively consists of a standard USB 2.0 Micro-B cable plug, with an additional 5 pins plug "stacked" to the side of it. In this way, cables with smaller 5 pin USB 2.0 Micro-B plugs can be plugged into devices with 10 contact USB 3.0 Micro-B receptacles and achieve backward compatibility.
12 V and 24 V powered USB sockets, on an NCR cash register. PoweredUSB, also known as Retail USB, USB PlusPower, USB +Power, and USB Power Plus, [1] is an addition to the Universal Serial Bus standard that allows for higher-power devices to obtain power through their USB host instead of requiring an independent power supply or external AC adapter.
A 12-volt outlet is any electrical outlet that outputs 12 volts and may refer to: Cigar lighter receptacle, the most famous example; Molex connector, used for connecting hard drives and optical drives, and sometimes for powering flash memory surrogate hard drive modules; Trailer lighting connector, has multiple prongs with 12 volts
The connectors are designed for 12V systems. Exceptions for the 7-pin connector may exist where they may be used for 6V and 24V. Vehicles and trailers with 6V systems can use the 7-pin or a 5-pin connector, but these are rare today. Heavy trucks that may have 12V systems are usually older (vintage vehicles) or on non-European markets. [1]
Comparison of (L to R) two Powerlet plugs, one combination plug, and one Cigar Lighter Plug. ISO 4165 is a standard adopted by the International Organization for Standardization (ISO) that describes a double-pole DC connector to supply between 12 and 24 V DC at up to 12 amps to appliances in vehicles.
For the 12 volt systems, the center contact is the positive terminal and the shell is the negative terminal. Most automobiles connect the negative terminal to the frame of the vehicle (negative ground). 12 volt auto connectors are made to comply with a standard by Underwriters Laboratories for safety. UL2089 was developed to cover the ...
An AC adapter or AC/DC adapter (also called a wall charger, power adapter, power brick, or wall wart) [1] is a type of external power supply, often enclosed in a case similar to an AC plug. [2] AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves.
