What is the default baud rate of serial port?
9600
Standard baud rates include 110, 300, 600, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200, 128000 and 256000 bits per second. To display the supported baud rates for the serial ports on your platform, refer to Finding Serial Port Information for Your Platform. The default value is 9600 .
Which baud rate is used normally for serial communication?
9600 baud
Baud rate is commonly used when discussing electronics that use serial communication. In the serial port context, “9600 baud” means that the serial port is capable of transferring a maximum of 9600 bits per second. At baud rates above 76,800, the cable length will need to be reduced.
What is the maximum baud rate of RS232?
I frequently run 115200baud on RS232 as do many other people. The maximum baudrate comes down to many factors, one is the RS232 interface chip, second is cable length and third is the sending/receiving systems as to whether they can cope with the data rate. With proper interface, you can easily reach 230400, and even 460800.
What is the maximum cable length for real-time RS-232 data?
What is the maximum cable length for real-time RS-232 data? Cable length is one of the most misunderstood items in the RS-232 world. The RS-232 standard was originally developed decades ago for a 19200 baud rate, and defines the maximum cable length as 50 feet, or the cable length equal to a capacitance of 2500 pF.
What is the maximum baud rate a cable can support?
General guidelines says most cables will support 115k baud, using x-on/x-off protocol (stop start is data on tx/rx lines) are limited to 30M, or about 100′ with shielded cable. UTP cables using this same protocol setup are limited to about half the speed, so maybe 56k.
What is the baud rate of a data transmission?
Data bits are sent with a predefined frequency, the baud rate. Both the transmitter and receiver must be programmed to use the same bit frequency. After the first bit is received, the receiver calculates at which moments the other data bits will be received.
