In theatre and performance venues, RS-485 networks are used to control lighting and other systems using the DMX512 protocol. RS-485 serves as a physical layer for the AES3 digital audio interconnect. RS-485 is also used in building automation as the simple bus wiring and long cable length is ideal for joining remote devices. It may be used to ...
Modbus or MODBUS is a client/server data communications protocol in the application layer. [1] It was originally designed for use with programmable logic controllers (PLCs), [2] but has become a de facto standard communication protocol for communication between industrial electronic devices in a wide range of buses and networks.
Optomux [1] is a serial (RS-422/RS485) network protocol originally developed by Opto 22 in 1982 which is used for industrial automation applications. Optomux is an ASCII protocol consisting of command messages and response messages containing data from an Optomux unit & contain a message checksum to ensure secure communications. The serial data ...
Block diagram for a UART. A universal asynchronous receiver-transmitter (UART / ˈ juː ɑːr t /) is a peripheral device for asynchronous serial communication in which the data format and transmission speeds are configurable.
Protocol information; Type of network: Open fieldbus and industrial Ethernet: Physical media: RS485, optical fiber, Ethernet (gigabit & 100Mbit) Network topology: bus, star, ring, line (depending on type)
The capability to set a bit rate does not imply that a working connection will result. Not all bit rates are possible with all serial ports. Some special-purpose protocols such as MIDI for musical instrument control, use serial data rates other than the teleprinter standards. Some serial port implementations can automatically choose a bit rate ...
A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232, RS-485, RS-422, or TTL-level UART serial data.
But it is often converted to RS485 or RS232. According to Emerson, [2] due to the huge installation base of 4–20 mA systems throughout the world, the HART Protocol is one of the most popular industrial protocols today. HART protocol has made a good transition protocol for users who wished to use the legacy 4–20 mA signals, but wanted to ...
