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.
In its first version Modbus used a two wire cable with EIA 485 UART signals. The protocol itself is very simple with a master/slave protocol and the number of data types are limited to those understood by PLCs at the time. Nevertheless, Modbus is (with its Modbus-TCP version) still one of the most used industrial networks, mainly in the ...
A male DE-9 connector on an IBM PC compatible computer (with serial port symbol) used for an RS-232 serial port A female DE-9 connector on an RS-232 cable.. A serial port is a serial communication interface through which information transfers in or out sequentially one bit at a time. [1]
The standard defines a 2-wire 18 gauge wire cable that can run up to 130 feet (40 m) and operates at 9600 bit/s. A message is composed of up to 21 characters, unless the engine is stopped and the vehicle is not moving in which case transmitters are allowed to exceed the 21 byte max message length.
MIL-STD-1553B does not specify the length of the cable. However, the maximum length of cable is directly related to the gauge of the cable conductor and time delay of the transmitted signal. A smaller conductor attenuates the signal more than a larger conductor. Typical propagation delay for a 1553B cable is 1.6 nanoseconds per foot.
