Product Description

IF TOOLS RS422/485 Analyzer



RS422 / 485 im Detail

The MSB-RS485 Analyzer is an essential tool for analysis and optimizing of RS422/ 485 connections. As an autonomous device it gathers exact information about every line change with micro second precision – indispensable for each analysis of time depending protocols like Modbus RTU, Profibus or similiar.

Equipped with a multitude of visualization tools it allows a detailed view in every RS422/485 communication and detects errors coming from bus enabling, timeouts or wrong/double addressing.



Versatile usage

Multiple connection modes allow the complete logging of all bus activities as well as the purposeful recording of data sent from selected bus participants.

Two additional auxiliary in/outputs serves for the correlation to further application signals.



Features & Benefits

The analyzer offers all necessary features for debugging, tests and 'Reverse Engineering'.

Why use an analyzer?


What a pure software solution cannot provide:


  • OS independent time stamps for all events (resolution 1µs)

  • Simultaneous display of the Tri-State signals as well as the transferred data


  • Detection of inactive bus states and invalid line levels


  • Measure and Set ANY baudrate from 1 Baud to 1 MBaud


  • Automatic detection of baudrate, databits and parity


  • Support of protocols with 9 bit data length




    Various bus connections

    makes it easy to analyze different bus systems like RS422 point-to-point including handshake, RS485 2-wire half-duplex and 4-wire full-duplex connections.


    Segment analysis

    Transparent bus separation for purposeful examination of single participants and separate recording of master and/or single slaves.
