How can you link RS232 serial data on COM1 to output on COM2?
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.
What is the Rs232 Cable?
Also known as a serial cable; typically with 9 or 25 pin D-sub connectors.
Difference between Ethernet and RS 485?
RS232 is for point to point communication where as RS 485 is for multidpoint communication, Voltage level and speed differ Hi frnds,, There are few points which v can discuss on these are 1) Ya first main important point is RS232 is point to point communication n RS485 is multidrope communication which means ... on RS232 u can not connect more than two device... RS485 u can connect upto I think max 128 device theorically..(its depends on noise level as well as on distance and burd rate also) Practicall as max 32... 2)Voltage level of RS232 is -3 to -25 for 1 +3 to +25V for 0 while RS485 is based on differential voltage (0-5v) diff is 240mV for 1 and -240mV for 0. 3)distance limitation is 100meter for RS232 and 1Km for RS485, 4)noise immunity is high for RS485 as it is balance protocol and differencial protocol.. 5)Software point of view u need to set transmit enable line in RS485 rest of the software is same... 6)pin for 232 is (Rx Tx and GND) while in case of RS485 it is (A(+) and B(-)) no need to transmit GND..signal
What is a serial connector?
Serial connector term is used for an interface connector on which the protocol of data transfer is serial type. Serial data transfer means one electrical connection or signal for data transfer (one bit at a time from transmitter to receiver) at specific speed (bits per second). Note that on the connector actually there may be more than one electrical connections for signals other than serial data, which include clock and power in some cases, or control signals. Serial data itself may be electrically sent in differential form in which case serial data itself needs two wires (positive and negative). Common examples of serial connectors include serial port (RS232) and USB.
What is 232 in RS232 and MAX232?
The difference between max232 and rs232 is the voltage levels of the rs232 are high. In order to reduce those voltage means to convert those voltage levels to TTL logic levels we use max232 integrated chip which is a dual driver/ receiver.
Full form of RS in RS232?
RS232 means "Recommended standard no. 232", EIA standard for serial communication Thirumalesha.....
What does the RS-232 standard apply to?
RS232 is a communications protocol for electronic devices to exchange information
What are the other serial communication standards other than RS232?
RS422 and RS485 and the now popular USB
What is the difference between i2c and rs232?
I2C (Inter-Integrated Circuit) is a serial communication protocol that uses two wire lines for communication, allowing multiple devices to be connected in a network. RS232 (Recommended Standard 232) is a serial communication standard that uses a single wire for data transfer and is commonly used for connecting devices like modems, printers, and GPS receivers. Additionally, RS232 uses voltage levels for signaling while I2C uses open-drain signals.
Make USB to RS232 converter?
Yes, you can get a USB to RS232 converter (aka USB to Serial).
What are the differences between UART and USB?
Different data rate speed (for rs232 is lower), usb is more flexible and takes less energy. Different instructions and commands. If you are a programmer then it's easier for to work with usb then with rs232.
Why is it necessary to have both serial parallel ports in computers?
Most newer hardware is using USB ports, however much of the legacy hardware uses older RS232 or parallel communication. They are all just different communication protocols and different hardware manufacturers selected whatever protocol THEY felt would be best for their application. Just about everything is USB now. It's far more flexible.
If there are RS232-to-USB adapters why are there no USB-to-RS232 serial adapters?
RS-232 serial ports are far slower than USB ports. With very few exceptions, devices that use USB ports would be impractical to use on a serial port.
Which part of the computer is associated with rs232 standard?
Data Terminal Equipment (Serial)
What are the types of serial communication?
There are four main types. 1:RS232 2:EIA232 3:EIA 422 4:RS485 The major difference lies in Range and Noise immunity.Hope this could answer what you need Wajahat
What is the difference between rs232 and rs485 port?
Difference between Rs232 and RS485 is Only Distance RS232 is not for long or far distance .. but RS485 can be use for LONGEST distance ..RS232 is single ended communication where as RS485 is Differential communication.Max.no of receivers in RS232 is only ONE, whereas in RS485 is 32.Max.no of transmitters in RS232 is only ONE whereas in RS485 is 32.IN RS232 there is no pin to change from transmitter mode receiver mode. But, In RS485 have DE pin to set transmitter mode and RI to set receiver mode.
How can you link RS232 serial data on COM1 to output on COM2?
Yes on a modern computer you will need a USB to 9 pin RS232 converter or previously use the LPT parallel port.
