RS-422 is a common transport mechanism for RS-232 extenders. These consist of RS-232 ports on either end of an RS-422 connection. Before hard-disk-based playout and editing systems were used, broadcast automation systems and post-production linear editing facilities used RS-422A [ check spelling ] to remotely control the players/recorders ...
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 ...
Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications between a master (e.g. controller) and a slave (e.g. sensor). SSI is based on RS-422 [1] standards and has a high protocol efficiency in addition to its implementation over various hardware platforms, making it very popular among sensor manufacturers.
At the application layer, the standard also defines the contents of each sentence (message) type, so that all listeners can parse messages accurately. While NMEA 0183 only defines an RS-422 transport, there also exists a de facto standard in which the sentences from NMEA 0183 are placed in UDP datagrams (one sentence per packet) and sent over ...
There is only one Bus Controller at a time on any MIL-STD-1553 bus. It initiates all message communication over the bus. Figure 1 shows 1553 data bus details: operates according to a command list stored in its local memory; commands the various Remote Terminals to send or receive messages; services any requests that it receives from the Remote ...
ARINC 429 is a data transfer standard for aircraft avionics. It uses a self-clocking, self-synchronizing data bus protocol (Tx and Rx are on separate ports). The physical connection wires are twisted pairs carrying balanced differential signaling.
If the delivery failure message says the account doesn't exist double check the spelling of the address you entered. A single misplaced letter could cause a delivery failure. If the message keeps getting bounced back, make sure the account is closed or hasn't been moved.
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.
