You can specify different settings for both ports including baud rate, parity, byte size, stop bits and flow control. The built-in scripting support offers the possibility to control several in-application objects with user-written scripts written in TypeScript (JavaScript superset).Being used with custom protocols parsing feature (Custom visualizers) and Serial Terminal / MODBUS Send it provides you with serial protocol automatic event control handler functionality. The built-in Serial Terminal module is used to create serial port terminal sessions. This exporter parses captured serial port data according to the loaded set of protocols, applies optional protocol-based filtering and Root Protocol and writes the resulting binary data into the output file. RS232 uses a single wire to transmit data, and the voltage levels on this wire represent the binary information being transmitted. These characteristics include: definition of a unit load, voltage ranges, open-circuit voltages, thresholds, and transient tolerance. The built-in protocol definition for parsing BACnet, a data communications protocol for Building Automation and Control Networks. What are the commonly used communication standards in industrial control systems? 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.

RS485 is used as the physical layer for many standards and proprietary automation protocols to implement control systems, most commonly Modbus. The Serial PPP View visualizer can be used to decode Point-to-Point Protocol packets, as well as a number of packets that can be encapsulated in PPP packets.PPP View supports the following protocols: Novell IPX, OSI Network Layer Control Protocol, DECnet Phase IV Control Protocol, Appletalk Control Protocol, Link Control Protocol, Password Authentication Protocol, Link Quality Report, Challenge Handshake Authentication Protocol, Multilink Protocol, Compression Control Protocol, Extensible Authentication Protocol, NETBIOS Protocol. MODBUS is an application layer messaging protocol, positioned at level 7 of the OSI model, that provides client/server communication between devices connected on different types of buses or networks.Serial MODBUS View visualizer parses MODBUS protocol requests and responses according to MODBUS APPLICATION PROTOCOL SPECIFICATION V1.1a. The serial bridge Data View visualizer has two panes. In the process of development of serial devices there is a necessity of their communication with PC via RS232 ports. The fastest RS-485 transceivers out there right now are running about 50 megabits. There is a whole plethora of SenseCAP industrial-grade sensors, and this is just one of the many!

Ready-to-deploy Industrial-grade Outdoor Enclosure: IP66 waterproof rate outdoor enclosure with window and waterproof ventilation hole reserved for light and gas sensors, also comes with a customized mounting panel. Structure View data visualizer is a two-part window. The serial Data View visualizer has two panes. It displays data that comes from one end of the virtual link in the top pane and data that comes from another end in the bottom pane.The contents of each pane can be copied into the Clipboard or exported into the file in various formats.Its unique data filtering capabilities make this visualizer a very handy serial bridge protocol analysis tool. In Complete mode the entire packet is decoded and all accompanying data is provided in Hex/ASCII view.The contents of the visualizer can be copied into the Clipboard or exported into the file in various formats. It displays incoming data in one pane and outgoing data in another one.The contents of each pane can be copied into the Clipboard or exported into the file in various formats.Its unique data filtering capabilities make this visualizer a very handy serial protocol analysis tool. With outstanding performance at the first place, the Request View visualizer is your best tool to analyze monitored data.

RS485 can have a cable length of up to 1200 meters(data rate is limited to 100kbps), useful for connecting distant devices. RS-485 can send data 1200 meters on cable. The visualizer has two windows, one of which displays data sent to the Serial device, and another one displays data received from the Serial device.All subsequent packets are concatenated into a single data stream, which is displayed as sequence of hexadecimal, decimal, octal, binary data and text. The Request View visualizer displays each monitored packet. For example, you may select a MODBUS protocol packet to see it decoded in Request View and MODBUS View visualizers. The serial bridge Request View visualizer displays each monitored packet. You can either select one of the predefined filters or create your own.Capture Filter can be used to discard entire packets according to specified criteria, while Display Filter can be used to hide packets from the specific Data Visualizer. Our product is the only one among all serial ports sniffers, which offers you the opportunity not only to monitor the data in real time, but also to record the received data in the log file with the possibility to replay and analyze it later.Using our product, you will not only be able to reproduce arbitrary fragments of previously recorded data on the screen, what is rs485 cable but also redirect them to a selected serial port (See "Data Repeater" feature).
