What is RS 232C control?

In simple terms, an RS-232 connection on a projector, for example, allows you to control the device remotely using a third party interface, such as a Macro Wall Controller, PC-based control software or a touch screen device such as an iPad or Android tablet connected to a control processor.

What is a RS 232C port?

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 a 9-pin connector called?

What is a DB9 Connector? The DB9 connector (originally named DE-9) is an analog socket, with 9 pins, from the D-Subminiatures (D-Sub) connector family. The DB9 has the smallest “footprint” of the D-Subminiature connectors. The prefix “D” represents the D-shape of the connector shell.

How many pins does RS232 have?

New RS232 has nine pins as mentioned earlier. These nine pins are arranged in the port as shown in RS232 Connector Pinout. The DCE and DTE ports are exactly similar except for the direction of data flow. These nine pins are roughly divided in to three categories and we will discuss each category below.

What are the characteristics of RS-232 interface?

It defines not only electrical signal characteristics, such as signal transmission rate, voltage levels, cable length, timing and short-circuit behavior, but many other things as well, including interface’s mechanical characteristics, connectors, and pinouts. According to RS-232 standard, all the data is transmitted in a time-series of bits.

How to establish RS232 interface with microcontroller?

MAX232 IC can be installed easily to establish RS232 interface with microcontrollers. Full duplex interface of RS232 is very convenient. Two pin simplex RS232 interface can also be established easily if required. The interface can be established up to a distance of 50 feet. Where RS232 is Used?

Why choose RS232 serial port monitoring hardware?

Thanks to RS232 serial port monitoring hardware, you should have no trouble capturing data and overcoming many of the latency and time-tagging problems commonly associated with traditional dual COM port monitoring solutions. RS232 serial port monitoring hardware stands out for a number of reasons, including its 9 pin RS232 pinout.
