RS-48 also known as TIA-485(-A), EIA-48 is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balance and multipoint systems are supported. The standard is jointly published by the Telecommunications Industry Association and. Basics-of-the-RS-485-Standard.

Example of an 8-pin connection . RS2has a separate communication line for transmitting and receiving which—with a well written protocol —allows higher effective data rates at the same bit rate than the . The MODBUS RTU ( Remote Terminal Unit) protocol is an efficient binary protocol.
It sends out a message which includes an Address. RS4Communications Interface. The addressed instrument alone replies by driving the RX line. This does mean that all the connected instruments must use the same software protocol – otherwise there will be confusion as to which instrument is being addressed. You must therefore know a minimum of MODBUS . This is a guide to the advantages and disadvantages of each communication protocol.
This protocol defines a message structure that controllers will recognize and use, regardless of the type of networks over which they communicate. It describes the process a controller uses to request access to another device, how it will respond to requests from the other devices, and how errors will be detected.

Operating Temperature Range. SECTION COMMAND INTRODUCTION. All data is sent and received in the ASCII. In some cases, they can perform serial-to-parallel and parallel-to-serial conversion or specify a basic data protocol.
Modbus is a serial protocol.
