Can RS232 be used for video?

Significantly in the AV industry, RS-232 does not transmit audio and video signals, but is used specifically for control of devices in an AV system; so source devices such as some BluRay players and digital media players, display devices such as televisions and projectors, as well as signal control products such as …

Are DB9 and VGA the same?

VGA Monitor (DB15 & DB9) The VGA connector can use a classic DB9 connector or (more commonly today) a DB15 style connector. The VGA connector (15 pin) is still widely used and while it was originally used to carry a 640 x 480 pixel format it is used to carry a variety of geometries including HDTV formats.

What is an RS 232 cable used for?

While USB has become the standard, RS232 is still widely used for older printers in the workplace. The RS232 protocol and cable allow the computer to give commands to the printer via a voltage signal. The printer then deciphers those commands and completes the print.

Can you convert serial port to VGA?

If your computer’s USB port is a Type A connector, you will have to get a USB Video Adapter of some kind. The varieties on sale include USB-to-VGA, USB-to-DVI, USB-to-DisplayPort, and USB-to-HDMI. Get one that matches your display monitor’s input type.

Is RS-232 a VGA cable?

But I’m curious because you say that the connectors look “exactly like VGA ports.” Usually RS232 utilizes a DB9 (DE9 for the educated and/or purist) with is the same size as a VGA (HD15) but has only 9 pins in two rows instead of 15 pins in three rows.

What does the RS in RS-232 stand for?

recommended standard
This standard, which was developed by the Electronic Industry Association and the Telecommunications Industry Association (EIA/TIA), is more popularly called simply RS-232, where RS stands for \”recommended standard. …

Is VGA a DB15?

Technically, no, it is different. DB15 is wider and has 15 pins in two rows of 7 and 8, while VGA, HD15 or DE15 (names are interchangeable) is a smaller connector that has 3 rows of 5.

What is a DB15 connector?

The DB15 connector is an analog socket, with 15 pins, from the D-Subminiatures (D-Sub) connector family. The prefix “D” represents the D-shape of the connector shell. The DB15 connector is mainly used in serial and parallel ports, allowing asynchronous data transmission according to the RS-232 standard (RS-232C).

What devices use RS232?

A serial port complying with the RS-232 standard was once a standard feature of many types of computers. Personal computers used them for connections not only to modems, but also to printers, computer mice, data storage, uninterruptible power supplies, and other peripheral devices.

Is VGA and serial the same thing?

No it will not work with a VGA monitor. If it is specifically marked as RS-232 (or with a string of one’s and zero’s), then it is a serial port for things like serial mice. If it on the other hand, it is marked with Mon. or a rectangle, then it is a DE-9 connector for CGA or EGA monitors.

What’s the difference between DB9 and RS-232?

RS-232 is a signalling standard, and DB9 is a connector standard. Most cables that are intended to carry RS-232 signals, have DB9 connectors — but some RS-232 cables have different connectors, and some cables for other signals have DB9 connectors. The Empeg cable is suitable for RS-232 (and has DB9 connectors).

What is the difference between RS-232, RS-422, and RS-485?

RS232 is full-duplex, RS485 is half-duplex, and RS422 is full-duplex. 2. RS485 and RS232 are only the physical protocol of communication (ie interface standard), RS485 is the differential transmission mode, RS232 is the single-ended transmission mode, but the communication program does not have much difference.

What is RS232 protocol and how it works?

RS232 is a serial information transfer protocol standard that defines both the protocol (method of transmission of data) and the physical hardware to do it. This document describes how it works at the physical level so you will know what signals you can expect to see at the microcontroller pins.
