Baud rate is a fundamental parameter in industrial networking transmission equipment. In Maiwe’s range of industrial switches, serial servers, industrial routers, industrial serial to cellular modem, edge gateways, and other communication devices, it is crucial to understand the "baud rate" parameter. So, what exactly is the baud rate and what is its function?
Baud Rate (Bd) measures the number of code element symbols transmitted per unit of time. It is a metric used to measure the rate of symbol transmission in a communication system. Each signaling unit that carries data information is called a code element or symbol. Thus, the baud rate is the number of these symbols transmitted per unit of time.
It's essential to distinguish between baud rate and bit rate:
Baud Rate: The number of symbols transmitted per second. Bit Rate: The number of bits transmitted per second.
The relationship between baud rate and bit rate is defined as:
Bit Rate=Baud Rate×Number of Bits per Symbol Bit Rate=Baud Rate×Number of Bits per Symbol
This means the bit rate is the product of the baud rate and the number of bits carried by each symbol.
Standard baud rates and their applications include:
Not all devices can support high baud rates. When setting the baud rate, ensure both communicating devices support the selected rate for stable and reliable communication.
When configuring industrial networking equipment, setting the correct baud rate is vital for several reasons:
The baud rate indicates how many code elements (symbols) are transmitted per second. The total number of code elements transmitted over a given time is determined by the baud rate. For instance, in binary modulation, each code element might carry 1 bit of information, while in more advanced modulation techniques, like quadrature amplitude modulation (QAM), each code element can carry multiple bits.
In summary, baud rate is a critical parameter in industrial networking equipment that affects data transmission speed and communication stability. Understanding and correctly setting the baud rate ensures efficient and error-free operation of industrial communication devices.
By highlighting these aspects, we can better understand the significance of baud rate in industrial networking and its practical implications for configuring and optimizing communication equipment.
