Jan 24, 2021 · RS232 is a serial communication standard primarily used for device communication, featuring two-way communication and primarily using 9-pin connectors. VGA is a display standard for transmitting analog video signals between computers and monitors, identifiable by its 15-pin connector.

Jun 30, 2024 · VGA and RS-232 are two distinct technologies with different purposes and functionalities. Understanding the basics of both can help clarify their differences and avoid confusion. VGA, which stands for Video Graphics Array, is primarily used for video output in computers and other devices.

Jan 22, 2024 · RS232 vs VGA - decoding the disparities. Explore the nuanced disparities between RS232 and VGA in our in-depth comparison. Uncover the essential dissimilarities and make an informed decision in your tech endeavors.

Jul 4, 2024 · RS-232 and VGA connections are two distinct communication interfaces commonly used in electronic devices. RS-232, also known as serial communication, is primarily used for connecting devices such as modems, printers, and GPS receivers to …

Nov 11, 2023 · RS232 and VGA have a similar connector design but serve very different purposes – RS232 for serial data transfer and VGA for video output. Both were game-changing when introduced decades ago but eventually got replaced by …

Dec 9, 2024 · While RS232 and VGA may seem disparate, they share some fundamental differences: Data Type: RS232 transmits digital data, while VGA transmits analog video …

Jan 29, 2025 · In a nutshell, RS232 enables communication between devices while VGA visualizes output on screens. Apart from the deceptive port shape, they serve distinct purposes.

May 23, 2007 · Like others have said RS232 is a serial control connection and not video. 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.

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.

Jan 29, 2019 · In the original RS-232, the signal would flip between positive and negative 25 volts. Since that point there have been three revisions, RS-232A, RS-232B, and RS-232C; these revisions lowered the acceptable voltage from 25 to 12 to 5 volts respectively.
