Introduction
The Accutron Pro is a true IIOT (Industrial Internet of Things) device. This unit offers system builders
unprecedented flexibility for instrument cluster interfacing, both to Industrial DCS as well the World
Wide Web. The Accutron Pro is designed to be easy to use and intuitive in its application. It provides a
host of “most wanted features” in a single stand alone product.
Unlike previous gateway and webserver combos, the Accutron Pro is all in one, combining a universal
multi protocol gateway (Modbus RTU & TCP, Ethernet IP™, etc), and integrated web server that can
display user settings for PC browsers or Smartphones. It has a fully compliant HTML5 interface.
The Accutron Pro also has advanced traffic logging that can log Ethernet TCPIP, as well as traffic on its
ports. In time of trouble the technician can access the traffic logs, and spot instrument timeouts, and
failures leading to rapid diagnosis of technical malfunctions. All this can be done without interrupting
the flow of DCS commands, thanks to the multi threading capability of the Accutron Pro. In fact, many
users can access the Accutron Pro simultaneously.
As new protocols and features are added, Accutron Pro firmware may easily be upgraded. This can be
done remotely over the network, or locally by a technician. Simply go to our website:
www.accutroninstruments.com and download the latest version available. Within seconds you can flash
our device underground from your office and you will be up to date with the latest and greatest version
of the Accutron Pro.
If you have any suggestions on improvements of this product, please share it with us. We value your
input. This product was designed to be user friendly and we are actively looking on how we can improve
our products to satisfy our customers.
