MSB-RS232: MSB-RS232 Analyzer - essential tool for RS232 connection analysis and optimization

EOL product replaced by IF-MSB-RS232-PLUSThe MSB-RS232 analyzer is an essential tool for analyzing and optimizing RS232 connections. 
It autonomously collects precise information on every line change with microsecond accuracy, independent of the PC and its operating system.

Equipped with a multitude of visualization tools, it provides a detailed view of every RS232 communication and detects conditions that can only be recorded by a *hardware solution*.
Simply insert the analyzer into any RS232 cable and connect it via USB to the computer.

**Why use an analyzer?**

A software solution cannot provide the same data offered by this device.
With the MBR-RS232 analyzer, you can examine the temporal relationships and exact sequences of all data and level changes, with the help of:

- Temporal event details independent of the operating system (1us resolution)
- Graphical view of the logical signal of all lines (including RXD, TXD), internal sampling frequency up to 16 MHz
- Measurement and setting of baud rate from 1 Baud to 1 MBaud
- Automatic scanner protocol for baud rate, data bits, and parity

**Features and Benefits**

The MSB-RS232 analyzer offers all the necessary features for effective examination of RS232 connections. 
Particularly for debugging, recording, testing, and *reverse engineering*.

The software for connecting to the analyzer is sold with the product and is compatible with all Windows operating systems and Linux. No other software or libraries are required on the PC.
