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.
With a vendor-supplied INF file, Windows Vista works with USB CDC and USB WMCDC devices. [1] This class can be used for industrial equipment such as CNC machinery to allow upgrading from older RS-232 serial controllers and robotics, since they can keep software compatibility. The device attaches to an RS-232 communications line and the ...
A software-based virtual serial port presents one or more virtual serial port identifiers on a PC which other applications can see and interact with as if they were real hardware ports, but the data sent and received to these virtual devices is handled by software that manipulates the transmitted and received data to grant greater functionality.
The standard specifies a maximum open-circuit voltage of 25 volts: signal levels of ±5 V, ±10 V, ±12 V, and ±15 V are all commonly seen depending on the voltages available to the line driver circuit. Many RS-232 driver chips have inbuilt charge pump circuitry to produce the required voltages from a 3 or 5 volt supply. RS-232 drivers and ...
IdeaPad (stylized as IDEAPΛD and formerly ideapad) is a line of consumer-oriented laptop computers designed, developed and marketed by Lenovo. The IdeaPad mainly competes against computers such as Acer 's Aspire , Dell 's Inspiron and XPS , HP 's Pavilion , Envy , Stream , and Spectre , Samsung 's Sens and Toshiba 's Satellite .
The Lenovo IdeaPad Yoga 11 is a hybrid laptop/tablet Windows RT-based computer released in late 2012. The Yoga 11 gets its name from its ability to change form factors thanks to the two-way hinge used to mount its display. It was discontinued on July 17, 2013, due to the poor sales of Windows RT devices. [1]
Starting in 2014, Lenovo changed the design of the ThinkPad bay adapter and dropped the "UltraBay" terminology from use. What remained (in the ThinkPad W540 product) was an option for a removable Serial ATA (SATA) "Caddy" accessory which, with a screw driver, allowed the optical drive to be replaced with a second 2.5 inch SATA storage device ...
These connectors are used to support RS-232 devices like modems, AppleTalk networking, RS-422 printers, and other peripherals. Two such ports were part of early Apple Macintosh series designs until they were replaced, along with ADB ports, by Universal Serial Bus on the iMac in 1998. RS-422 is a common transport mechanism for RS-232 extenders.
