Are there different types of RS232?

The RS-232 specification defines two types of serial devices, DTE and DCE. DTE normally refers to the serial port on a PC or terminal, while DCE refers to a modem or other type of communications device.

What type of cable is serial cable?

A serial cable is a cable that can be used to transfer information between two devices using serial communication, often using the RS-232 standard. Serial cables may use D-subminiature connectors, like DB9 or DB25 pins, but other connectors are used.

Is RS232 and serial the same?

RS-232 signals are similar to your microcontroller’s serial signals in that they transmit one bit at a time, at a specific baud rate, with or without parity and/or stop bits. The two differ solely at a hardware level. On most PCs these signals swing from -13 to +13V.

What is a RS232 serial cable?

RS232 is a standard protocol used for serial communication, it is used for connecting computer and its peripheral devices to allow serial data exchange between them. As EIA defines, the RS232 is used for connecting Data Transmission Equipment (DTE) and Data Communication Equipment (DCE).

What is RS232 crossover cable?

A null modem serial cable (frequently called a crossover cable) is used to connect two DTE devices together without the use of a DCE device in between. For this to happen, the Transmit (TXD) and Receive (RXD) pins on one of the serial connectors are flipped.

Is RS232 a DB9?

Below is the pinout of a typical standard male 9-pin RS232 connector, this connector type is also referred to as a DB9 connector.

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 function of a RS-232C port?

RS-232C is the interface that your computer uses to talk to and exchange data with your modem and other serial devices.

What is RS232C control?

RS-232 is a control protocol used by AV gear, primarily in the home automation market. RS-232 control is a wired protocol that is loved by custom integrators because the locking connectors rarely fall out and the connections are fast and robust.

What is serial cable?

Serial cables are typically used for RS-232 communication. A serial cable is a cable used to transfer information between two devices using a serial communication protocol. The form of connectors depends on the particular serial port used. A cable wired for connecting two DTEs directly is known as a null modem cable.
