It is used to monitor the serial connection between two distinct serial devices. Basic Serial Monitor functionality includes the ability to view and navigate monitored serial data. With outstanding performance at the first place, the Request View visualizer is your best tool to analyze monitored data. Root protocol, a feature of Structure View data visualizer, as well as several other components, allows the user to focus on a specific protocol frame inside another encapsulating protocol. Using custom protocol feature you can parse any SCADA industrial protocol which is transmitted over RS485, RS422 or RS232 serial connection, dial up/radio modem or TCP/IP, UDP/IP network. The characteristic feature of the Daisy Chain topology is the sequential connection of each device along a single line, not forming a loop structure. Ring topology arranges network nodes in a circular configuration where each node connects to two others, forming a closed loop. While four-wire full-duplex exists, it is less prevalent in current applications, with the two-wire half-duplex configuration being the predominant wiring method in use today.

Different topology designs suit different network needs and applications, affecting performance, reliability, and scalability. 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. RS485 is used in many computer and automation systems. Network topology refers to the arrangement of various nodes (such as computers, servers, switches) in a computer network. This topology offers efficient data transfer but can be disrupted if any single connection breaks, though redundancy protocols can mitigate this risk by providing alternative pathways for data. It allows for automatic transceiving, providing convenience. RS485 at its core with 2 wires allows half-duplex data transmission. Default, all the senders on the RS485 bus are in tri-state with high impedance. This is, because on the other interfaces the communication channel is shared by multiple receivers and-in the case of RS485-by multiple senders. The request and acknowledge data needed in most protocols does not consume bandwidth on the primary data channel of RS232.

And what is a RS232 to RS422 converter? 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. Our product has not only a complete set of tools for this, but also the means to automate this process. RS485 provides a means of interconnecting multiple devices in a series using a twisted pair of wires to facilitate data exchange. The entire daisy chain network is ultimately connected to a PLC (Programmable Logic Controller), facilitating data exchange between multiple devices and the central control system. Among various topological structures, the Daisy Chain topology is considered the optimal choice for RS-485 due to its minimal impact on signal integrity. Devices (Device 1, Device 2, Device N) are connected in series, forming a daisy chain topology. Our security solution products are based upon cutting edge technologies that are unique in the security industry. There are different families of products on the market: instruments which measure a single electrical parameter (voltage, current, frequency, and phase angle cosϕ), generally used in single-phase systems, as instrumentation on the machine, and instruments allowing all the electrical parameters to be measured and displayed, both for the single-phase system and for the three-phase system.

Our range of IIoT products is wide, with different sensors and hubs for different scenarios and requirements. It is the reason why RS485 is so popular with computers, PLCs, micro controllers and intelligent sensors in scientific and technical applications. Network topology is probably the reason why RS485 is now the favorite of the four mentioned interfaces in data acquisition and control applications. And now the most important question, how does RS485 function in practice? This is comparable with the way ethernet networks function. Serial communication is a way to send data. Ultimately, it can be thought of in a way that serial communication is more made for this usage as compared to the common USB and ethernet. And that with an interface which does not require intelligent network hardware: the implementation on the software side is not much more difficult than with RS232. Interesting is, that RS232 is the only interface capable of full duplex communication. RS485 is used as the electrical layer for many well known interface standards, including Profibus and Modbus. To illustrate, let's consider LORRIC's paddle wheel flowmeter, which utilizes Modbus as the underlying protocol for defining various signal transmissions. Devices utilizing RS485 can communicate with central control systems using communication protocols such as Modbus and ASCII.
