What is Serial Communication? > 자유게시판

Download this COM port analyzer now and start spying serial ports in a few seconds! Note. We are developing an online serial port monitor now. Star and ring topologies are not recommended because of signal reflections or excessively low or high termination impedance. B- lines, with high and low voltages representing binary 1 and 0 (on and off), ensuring reliable data communication. Cable jacket: Made from high-quality PVC, the outermost jacket layer has high elasticity, helping to protect the cable from strong environmental impacts. Serial port monitoring and data processing algorithms are extremely optimized in order to provide you with slick user experience and eliminate all negative impact on operating system performance, stability, computer resources consumption, and introduction of communication delays even at high non-standard data transfer rates. The lower pane lists all other supported and installed visualizers which are used to display the individual packet information. It formats its textual output exactly like the upper part of the Structure View data visualizer, but does not display any UI, writing formatted data directly to the file. It is an approved and standard protocol by American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), American National Standards Institute (ANSI), and International Organization for Standardization (ISO).Use with Structure View data visualizer, Text Exporter or Custom View data visualizer to get full insight on underlying protocol messages exchanged by devices on your network.

So in order to transfer data from a RS232 serial interface engineers need a converter to be able to connect to a RS485 or RS422 interface. There are control requests that configure port parameters as well as data transfer requests that pass data between application and serial device. There are several factors to consider when choosing a RS232 - RS422 converter. The RS232 - RS422 converter is also often used in older serial devices such as older PLC's and terminal equipment. The reason is that the serial RS232 protocol is, even its old, a very reliable, stable and solid communication protocol, which can easily be implemented with existing industrial equipment. The RS422 converter is used for data transmission, using balanced or differential signaling, it is mainly used in industrial and commercial environments since lots of process equipment and machinery have this protocol built-in. Due to loading limitations one of the best uses of a RS232 to RS422 serial converter might be in point-to-point communications, such as extending an existing RS232 line.

With outstanding performance at the first place, the Request View visualizer is your best tool to analyze monitored data. The user can add his own protocols using the simple yet powerful protocol definition language.Each monitored data packet is parsed according to the configured protocols. However since only a true RS485 network can have addressable serial RS485 devices, the RS232 converter needs to be addressable either by software or by DIP switches when using it in this type of configuration. A wide set of built-in and custom data visualizers and exporters are provided to give the user powerful insight on the monitored data.The built-in powerful Serial Terminal module provides a versatile terminal emulation environment which can be used in collaboration with a running monitoring session.Serial Monitor provides rich support for MODBUS protocol and devices, including specialized data visualizers, MODBUS Send window (MODBUS packet builder and sender) and full MODBUS protocol definition.Virtually every component of the Serial Monitor may be programmatically controlled by a running script, written in TypeScript (superset of JavaScript).Download this software rs232/rs422/rs485 serial protocol analyzer now!

In areas with a lot of signal interference, the software may need to perform multiple inquiries to get a valid response. In contrast to EIA-485 (which is multi-point instead of multi-drop), EIA-422/V.11 does not allow multiple drivers but only multiple receivers. The advantage of the RS485 protocol is that this it can transfer data over longer distances, up to 4000 feet, and have up to 32 nodes per single network, and it can be used for multi-point networks where multiple serial devices are setup in a bus network. Usually a RS232 - RS485 converter is the preferred way to establish multi-point networks when working with RS232 devices. The RS485 converter interface uses two wires for communication, one for transmitting and one for receiving data, which is referred to as a half-duplex communication converter. The application's various editions include features for filtering, browsing, searching, recording, and data playback.Serial Monitor provides not only a wide range of visualization tools for popular serial protocols (including PPP, MODBUS, BACnet MSTP) and raw data, but also utilities for creating your own custom visualizers, allowing you to parse any data and custom protocols in a convenient way.
