Pin 2: RXD — The data is received by the computer in serial order by the receive pin. It is also permanently set by the hardware. Hardware flow control is very useful when there is mismatching between the transmitter and receiver in terms of rate of speed.
Pin 6: DSR: Data Set Ready pin is generally utilized in devices like modem to tell computer that it is ready to take data. It tells the device to disconnect from computer. It is used to by computer to detect whether the device has been disconnected from it.
Apart from the disconnection between computer and the device, it also detects whether the connected device has lost its other connections. For example, in a modem, computer can detect whether it has lost it connection from the phone line. It is a one way type of communication taking place from modem to computer.
It also acts as reference point from where signals can be measured. Step by Step Working of RS After having a brief reference of the pins and signaling let us see the working of RS by an example. Let us we have a modem that utilizes RS to communicate with computer.
The processes taking place are briefly described below:. As the modem is connected to the computer, It modem sends a software based Ring Indicator RI signal to computer. The computer gives response to the modem by sending DTR signal i. Data Terminal Ready. It tells modem that computer is ready to undergo communication with modem and ready to receive data.
In full duplex communication, both CTS and RTS pins are raised high while in half duplex mode they are utilized for handshaking necessary to control the direction. Hence the communication ends up. RS in Real World:. However there are certain devices that uses RS port for the communication with computer like dot matrix printers , modem etc. Most of the devices build today are not able to communicate with the RS world due to voltage differences between them.
Thus to have serial communication it is necessary to have level conversion. This level conversion is done by using specifically designed integrated circuits IC. It consists of amplifiers called as line drivers which improve signal strength and set the voltage levels according to receiver unit so that it does not get damaged.
Therefore whenever they receive signal, it is inverted from its initial state. It also acts as an intermediate between serial and parallel communication i. It converts byte of data into a single stream when transmitting and converts the bit of data i.
Thus now we can understand the implementation of RS in real world applications. RS vs. This replacement took place because first of all rs has many pins, and then it is again divided into male and female type connectors. Apart from its physical smartness there are other disadvantages too such as:.
The USB ports due to their compact size are usually present in the modern computers. A computer may possess two to eight USB ports. On the other hand RS ports are too bulky and cover more space then the USB which makes it one of the reasons behind its extinction from modern world. The RS comes in two configurations i. D-style 9 pin and 25 pin connector. One for the printer or modem etc and another one for mouse etc. This increases connectivity of computer. There is a vast difference between the speeds of both the ports.
The RS transmits by sending single bit of data over every clock cycle. The rate of clock pulses ranges from to Roughly estimating, the speed provided by RS is approximately 10Mbps for internet usage. However, the speed provided by the USB is generally limited by the factors such as number of devices connected to the same bus and also on the speed of the host computer. The USB port has an inbuilt power supply of 5 volts along with the signaling pins.
The devices nowadays utilize 5 volt or less to operate. Thus, one does not need an external cord to power them, they can effectively use the power provided by the USB port. If you are looking for an RS serial standard, knowing what types are available, how they work, and how you can maintain them may help you find the one that works for you. If you have a preferred electronics brand, you may be able to purchase RS standard cables from it.
Some brands that might stock these products include:. All male-to-male cables share common characteristics that may include an unshielded prong or attachment and the ability to fit into a female serial port. However, these connectors may be available in a variety of formats, depending on your specific need. Some common types you may find during your search include:.
RS serial units may use different versions of the D-subminiature specification depending on the specific model you choose. Some of the most common types you might find during your search include:. How two or more devices interface with one another depends on the types of devices you are using.
There are two primary categories from which you can choose:. USB 2. What brands produce RS cables? Some brands that might stock these products include: APC : This American manufacturer has been producing peripherals and connectors for electronics for decades. Belkin : Belkin has specialized in connectivity products for personal and professional computing for 35 years.
