Driver Installation

Stratus Engineering’s EZ-Tap™ hardware module offers a low-cost hardware bus analyzer and protocol analyzer solution that uses a traditional dual COM port approach to RS232 interface monitoring. It is fully compatible with our free EZ-View monitoring software as well as most third-party dual COM port/serial port monitoring programs and eliminates bulky cables that are typically associated with these solutions.

EZ-Tap’s features include:

  • Supports standard and non-standard baud rates as high as 921600 bits/sec.
  • Includes PC-compatible device drivers, 6ft “Mini-B” USB cable and EZ-View RS232 monitor program that interfaces directly to EZ-Tap hardware for low-latency USB access.
  • DLL-based Windows API with low-level time-tagging available for custom application development.
  • 30-day money-back guarantee.
  • Serial port monitor that is compatible with Windows 2000/XP/Vista/7/10 (both x32 and x 64).

RS232 Tutorial

Our RS232 tutorial offers comprehensive information about how to make the most of your EZ-Tap experience. It details how to use RS232 and features RS232 protocol basics, ensuring you can leverage EZ-Tap quickly and efficiently at all times.

Driver Installation

Unzip the driver files into a directory on your drive and use the Windows hardware installation wizard to complete the install. After the EZ-Tap driver has been correctly installed, EZ-Tap will be shown as two sequentially numbered COM ports under Windows Device Manager.

RS232 Monitor Application

EZ-Tap uses the receive channel from each of two USB COM ports to capture RS232 ad bidirectional RS232 data. There are several software options you can use to acquire and display, including:

Option 1 – Windows RS232 Terminal Program

Use a simple terminal program such as Hyperterminal to capture RS232 data traffic. Open two instances of the terminal program and assign one of the two EZ-Tap COM ports to each. Be sure to set up the correct COM parameters (baud rate, etc.). The RS232 traffic will then be displayed in the terminal windows as it is transmitted.

Option 2 – Third-Party RS232 Monitor Programs

Use one of the many commercially available third-party RS232 monitor programs. Most of these programs are designed to work with a custom passive tap cable and two COM ports. EZ-Tap is fully compatible with this mode of operation – simply assign the EZ-Tap COM ports in the program’s COM port settings.

Option 3 – Use the EZ-View RS232 Monitor Program

Our EZ-View RS232 Monitor program delivers the best software solution for applications that demand higher performance. EZ-View bypasses the Windows virtual COM port layer and interfaces directly to EZ-Tap hardware for low-latency access.

Option 4 – Develop Custom Software Using the EZ-Tap Windows API

For users requiring more sophisticated data extraction and analysis, we provide the EZ-Tap API, a Windows-DLL that allows you to develop custom software that interfaces directly with EZ-Tap. The EZ-Tap API interfaces directly to EZ-Tap hardware for low-latency access and provides sub-millisecond data time-tagging.
