Free Data Monitoring Software for EZ-Tap™, EZ-Pro™, and Versa-Tap™ Passive Tap Modules

Free EZ-View™ Data Monitoring Software

Stratus Engineering's EZ-View™ data monitoring program controls communication and data collection parameters and displays time-tagged communication data and handshaking events in an easy-to-use scrolling display window.

EZ-View™ is fully compatible with Stratus Engineering's EZ-TapEZ-Tap Pro and Versa-Tap hardware modules.

EZ-View™ automatically detects the hardware configuration and provides a consistent, hardware independent user interface. When used with EZ-Tap Pro and Versa-TapEZ-View provides perfect data ordering with exact microsecond time-tagging of all data and handshaking events.

EZ-View application program V1.6.20 (Recommended)

Docklight and Docklight Scripting

Docklight and Docklight Scripting are sophisticated testing, analysis and simulation tools for serial communication protocols. They significantly increases productivity in a broad range of industries, including automation and control, communications, automotive, equipment manufacturers, embedded and consumer products. The free evaluation versions can be used for unlimited time and allow basic data monitoring using EZ-TapEZ-Tap Pro and Versa-Tap hardware modules.

Please refer to for more information on these powerful tools.

Custom Application Development with the Windows API

For users requiring more sophisticated data extraction and analysis capabilities, Stratus Engineering provides a windows API that allows the user to develop custom software that interfaces directly with EZ-TapEZ-Tap Pro and Versa-Tap hardware modules. Please contact us at for more information on this API and example interface software.

Other RS232 Monitor Application Options for the standard EZ-Tap Module

The standard EZ-Tap module uses the receive channel from each of two USB COM ports to capture RS232 and bidirectional RS232 data. There are several other software options you can use to acquire and display with standard EZ-Tap.

Windows RS232 Terminal Program

Use a simple terminal program such as Hyperterminal to capture the RS232 data traffic. Open two instances of the terminal program and assign one of the 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.

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.

EZ-View RS232 Monitor Program

EZ-View RS232 Monitor program serves 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.
