RS485 Sniffer
RS485 Analyzer Software

RS485 Sniffer is a system utility to collect data that goes through COM ports of your PC. Essentially, this RS485 communication software performs the following functions – monitors and records data exchanged with a serial port so you can use it for further analysis and, if required, trouble-shooting. This is of critical importance for development and testing of applications, drivers and serial devices.

This RS485 monitor software has a number of additional features, including advanced filtering and search, terminal mode and options to export data in various formats. Clean interface and intuitive navigation make RS485 Sniffer extremely easy-to-use.

RS485 Sniffer enables you to:

  • Monitor data

    You can connect to a serial port anytime – even if there is a device connected to it -and start collecting and displaying IOCTLs (input/ output control codes) instantaneously. Capability of this RS485 data logger to capture full information in the real time mode makes it possible to identify and correct problems on time.
  • Monitor several ports within one session

    This RS485 analyzer makes it possible to watch multiple ports at a time, i.e. you can intercept data on interaction of application with multiple ports and devices. All of this is done within one session, the output – a single log where data is arranged on a first-in-first-out basis – is easy to analyze.
  • Record data

    Information can be redirected and recorded in a specified folder. You can also copy it to a clipboard to paste it wherever you need to. RS485 protocol analyzer enables saving monitoring sessions so you can get back to them when required.
  • View data

    There are 4 modes – table, line, dump and terminal – you can choose from when browsing data. Each suits a particular purpose. RS485 Sniffer offers convenient filtering options so you can view only relevant parameters without being distracted by excess information.
  • Simulate sending data

    To check a reaction of a monitored device to a particular command or data, it might be required to simulate sending data to a serial port. RS422 Monitor allows you to do that, formats supported include string, binary, octal, decimal, hexadecimal, mixed.
  • Analyze Modbus RTU and ASCII data

    RS485 Protocol Analyzer allows to view and analyze communication data sent via Modbus ASCII and RTU protocols. With this RS485 communication software you will be able to monitor and analyze the activity of serial devices.
  • Reproduce and compare monitoring sessions

    RS485 Port Sniffer offers a special session playback possibility - you can send information got from the application to the RS485 port once more. It means that you can resend data received from the app to the serial port. This allows reviewing port's behavior on receipt of the same data for as many times as needed. Sessions can be compared with the possibility to automatically display the differences between them.

    Without the RS485 Port Monitor from Electronic Team, I would not have been able to easily and quickly see the operation of the several serial ports carrying data to the navigation program...
