Correspondingly, hOW FAR CAN serial cable go?

The RS-232 standard specifies this as 15 metres (50 feet). However this is a conservative figure accounting for high serial speeds over high capacitance cabling, for example using a baud rate of 9600 (a common console speed) over typical Cat 5 cabling, the maximum length increases to 100 – 150 meters (328 – 500 feet).

Secondly, what is the value of maximum data rate in RS 232 standard? X. 21
SPECIFICATIONS RS232
Total Number of Drivers and Receivers on One Line 1 DRIVER 1 RECVR
Maximum Cable Length 50 FT.
Maximum Data Rate 20kb/s
Maximum Driver Output Voltage +/-25V

Similarly, you may ask, what is the accepted distance limitation of RS 232 communications when following standard wiring practices?

RS232 (single-ended) was introduced in 1962, and despite rumors for its early demise, has remained widely used through the industry. The specification allows for data transmission from one transmitter to one receiver at relatively slow data rates (up to 20K bits/second) and short distances (up to 50Ft.

What is a RS 232c port?

)Short for recommended standard-232C, a standard interface approved by the Electronic Industries Alliance (EIA) for connecting serial devices. In addition to modems, many display screens, mice, and serial printers are designed to connect to a EIA-232 port.

How fast is a baud?

One of the more common baud rates, especially for simple stuff where speed isn't critical, is 9600 bps. Other "standard" baud are 1200, 2400, 4800, 19200, 38400, 57600, and 115200. The higher a baud rate goes, the faster data is sent/received, but there are limits to how fast data can be transferred.

What is the difference between rs232 and rs485?

1. RS232 is full-duplex, RS485 is half-duplex, and RS422 is full-duplex. RS485 and RS232 are only the physical protocol of communication (ie interface standard), RS485 is the differential transmission mode, RS232 is the single-ended transmission mode, but the communication program does not have much difference.

What is rs422 used for?

RS422 was introduced to enable higher data rates to be transferred over serial data lines than was possible with RS232. RS422 is able to provide data rates of up to 10 Mbps at distances up to 50 feet (15.24 metres).

What is rs485 cable?

EIA-485 (formerly RS-485 or RS485) is a specification for the physical layer of a network that uses the difference in voltages between two wires (Three wire) to conveys data. The resistance of the twisted pair cable will drop the voltage difference as it travels down the wire.

What type of connector is used for a telephone cable?

The most widely implemented registered jack in telecommunications is the RJ11. This is a modular connector wired for one telephone line, using the center two contacts of six available positions.

Does rs232 cable need to be shielded?

RS-232 serial interface cables should be shielded, low capacitance cables, ideally designed specifically for serial data transmission. The shield should be grounded at both ends of the cable.

How many wires does rs232 use?

The original pinout for RS232 was developed for a 25 pins sub D connector. Since the introduction of the smaller serial port on the IBM-AT, 9 pins RS232 connectors are commonly used.

What do you mean by serial port?

In computing, a serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. Throughout most of the history of personal computers, data was transferred through serial ports to devices such as modems, terminals, and various peripherals.

What voltage is rs485?

Characteristics of RS485 compared to RS232, RS422 and RS423
RS232 RS485
Driver load impedance 3..7 kΩ 54 Ω
Receiver input sensitivity ±3 V ±200 mV
Receiver input range ±15 V –7..12 V
Max driver output voltage ±25 V –7..12 V

Is rs232 full duplex?

Full duplex communication means that a device can receive and transmit data at the same time. Half duplex means that the device cannot send and receive at the same time. It can do them both, but not at the same time. The RS232 specification governs the physical and electrical characteristics of serial communications.

How are rs232 signals measured?

To measure single RS-232 signals, a measuring instrument with at least one channel is required. To measure full-duplex signals, an instrument with at least two channels is required. The maximum frequency on the RS-232 bus depends on the bit rate that is used.

What is rs232 port used for?

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 it obtains the voltage for the path used for the data exchange between the devices.

Is rs232 same as VGA?

Serial Port (RS232) was first implemented in the 1960's and is obsolete since long. It was used to connect mouse, printers, modems etc but had many VGA is a graphics interface which uses RGB analog signals as video output. It's technical name is DE15 connector.

Is rs232 bidirectional?

Bidirectional RS-232 Communication Uses Only One I/O Line. Occasionally, when designing with microcontrollers, it's necessary to include a bidirectional serial communications capability, but, only a single I/O line is available. The microcontroller tries to output a low to the RS-232 driver.

How does an rs232 work?

The RS232 is a communication cable, generally used to transfer and receive the serial data between two devices This cable supports both synchronous and asynchronous data transmissions. A serial port sends and receives data one bit at a time over one wire very slowly.
