RS-485, also known as TIA-485(-A) or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced , and multipoint systems are supported.
When a new communication technology or product is being developed, hardware and software engineers rely heavily on protocol analyzers, also known as sniffers or bus analyzers to identify problems and speed the development process. Frontline provides PC-based protocol analyzers for developers and industrial applications.
The hardware utilized are RS-485 transceivers wired for open collector ... SAE J1708, although still widely used, is replaced by SAE J1939 which is a CAN protocol.
When developing or troubleshooting for MIL-STD-1553, examination of the electronic signals is useful. A logic analyzer with protocol-decoding capability, also a bus analyzer or protocol analyzer, are useful tools to collect, analyze, decode and store the waveforms of the high-speed electronic signals.
AISG protocol is based on half duplex communication and HDLC protocol. The AISG bus is a single master multi slave bus. Communication media can be either RS-485 based using a dedicated cable specified in the AISG standard or OOK carrier injected into the RF antenna feeder cable of a base station site. The master controlling the communication is ...
The transmitter constantly transmits either 32-bit data words or the NULL state (0 Volts). A single wire pair is limited to one transmitter and no more than 20 receivers. The protocol allows for self-clocking at the receiver end, thus eliminating the need to transmit clocking data. ARINC 429 is an alternative to MIL-STD-1553.
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 ...
A protocol analyzer is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel.Such a channel varies from a local computer bus to a satellite link, that provides a means of communication using a standard communication protocol (networked or point-to-point).
