Notation Converter

An easy to use 32-bit notation converter is provided for rapid conversion between binary, decimal and hexadecimal.


An ASCII Table is provided for reference. ASCII characters 00-7F hexadecimal are displayed in various notations.

User Notes

A feature rich single page notepad is provided for storing handy notes or data (during a debugging session for example).

Macro List

To aid in efficient and productive testing/debugging, a Macro List Pane is included. “Macros” are a convenient way to store commonly used data or actions.

Visual Scripting

There is also a "Visual Scripting" feature to run/execute macros in sequence or repeatedly in a loop. This can be of great help for debugging or testing the robustness of RS232 based embedded systems without resorting to any programming. It is equally powerful for testing a variety of equipment by executing a sequence of macros/tasks written to exercise that equipment.
