Serial interface analyser and universal serial interface converter.


THE VINCI EXPERT Industrial design inspired by Leonardo da Vinci’s illustration “Vitruvian Man”, which represents the golden ratio of the human body. The elements are positioned so that they would prolong the lines of the drawn figure and create a perfectly ergonomic shape of the device, convenient to handle every day. The positioning of each component, button and LED is calculated according to the golden section ratio and Fibonacci sequence to make not only the appearing of the tool visually aesthetic, but also to create the whole product extremely comfortable to use. For sure you will love it.

THE VINCI EXPERT helps you to MONITOR what is being transmitted over RS232, RS485, RS422 and even over fiber optical cable in order to make communication between devices. THE VINCI EXPERT is especially helpful in product development, testing and commissioning stages. It supports Modbus, DNP, IEC 60870-5-xxx and other serial protocols.

THE VINCI EXPERT helps you to CONVERT serial interfaces. It is a powerful tool, which allows you to change serial interface from RS232 to RS485/RS422 or to the Fiber optic. Any other combinations are supported as well. Whether you are developing a new solution or considering obtaining a converter, THE VINCI EXPERT is a wise choice.


The package includes The Vinci Expert hardware + The Vinci Software (with Premium licence) + all necessary gender adapters, fiber optic and UTP cables + traveling case.


Unique design of hardware with precise agility in details deliberated design and features makes The Vinci Expert perfectly fit for commissioning engineers to be used at work with serial communication lines.

Device is designed by having in mind ENGINEER as most important person and all details was polished to fit into they needs.

RS232 interface designed to setup any pinout in software and save that configuration for future needs. It allow fast and unlimited cabling capabilities for RTU’s, PLC’s, Modems, IED’s and any other equipment.

RS422/RS485 interface designed to easy switch from 422 to 485, add terminating resistors and even switch pin parity in software.

Fiber optical lines designed for multimode serial communication lines to perfectly fit into site communication needs based on serial communication lines. That allows to interconnect between IED and RTU, Telco equipment be used as interface converter from Fiber to serial as well as fiber optics to PC. Additionally to that The Vinci Expert with The Vinci Software is capable to measure fiber optical line budget.

Buttons located on The Vinci Expert enables to use simple functions like Light On mode for fiber optical line, Null modem cabling for RS232 line, and RS422 to RS485 switching. And unique isolate button allows to isolate communication between sides A and B that traffic would be send only to USB serial ports.

The Vinci expert has embedded magnets on bottom side to perfectly stick on metal cabinet wall or metal equipment.
