Device Driver Installation

Please visit downloads page to download the latest copy of this file and the Versa-Tap device drivers and installation guide for your operating system.

Note that EZ-Tap™, EZTap Pro™ and Versa-Tap leverage the same device driver. A user can unzip the driver files into a directory on his/her hard drive and use the Windows hardware installation wizard to complete the installation. If this does not work for you, refer to the instructions in the appropriate driver installation guide for help.

Once the driver has been correctly installed, Versa-Tap will be shown as a USB COM port under Windows Device Manager.

EZ-View™ RS232 Monitor Application

Our EZ-View RS232 Monitor program Version or higher is required when using the Versa-Tap hardware module.

EZ-View now works with EZ-Tap, EZ-Tap Pro, and Versa-Tap and offers the same user interface for all devices. The only difference between the two devices from the EZ-View user standpoint is that EZ-View provides exact microsecond time-tagging for all data and handshaking events when used with EZ-Tap Pro or Versa-Tap. You can download the latest version of EZ-View on our downloads page.

Developing Custom Software with the EZ-Tap/EZ=Tap Pro/Versa-Tap Windows API

For users requiring more sophisticated data extraction and analysis, we provide the EZTap/EZ-Tap Pro/Versa-Tap API, a Windows-DLL that allows the user to develop custom software that interfaces directly with Versa-Tap. The API interfaces directly to Versa-Tap hardware for low-latency access and provides exact microsecond timing for all data and handshaking events.

Versa-Tap requires Driver DLL version 1.6 or higher.

Connecting Versa-Tap to the System Being Tested

Once Versa-Tap and EZ-View are operating correctly on the MS Windows PC host system, the user must create a custom connection to the system under test.

The Versa-Tap screw-terminals are labeled with their RS2332 and RS422 signal name. Note that you must select between RS232/TTL, RS422 and Inverted RS232/TTL signaling level under EZ-View.

Stratus Engineering’s Versa-Tap™ protocol analyzer offers a powerful hardware solution that features state-of-the art electronics and provides exceptional data-logging/analyzer capabilities at a fraction of the cost of the nearest competitor.
