What is the difference between RS-232 and RS-232C?

Because this adoption date was so long ago, most manufacturers, including National Instruments, have dropped the “C” from the name and simply refer to the protocol as RS-232. In common, modern usage, there is no difference between RS-232 and RS-232C, protocol.

Can RS-232 be used for video?

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 is a RS-232C port used for?

An RS-232 serial port is most often used by repair technicians to perform diagnostics and service updates. It may also be used to control a device when connected to a computer running a home automation system or Custom Integrated Audio/Video (A/V) system, such as the CAV-M1000ES Multi-room A/V Distribution System.

What is remote RS-232C?
