The EST4 Configuration Utility (CU) replaces the manual look-up tables and compilation requirements of the EST3 with a graphical tree view that matches the system's physical layout (Page 4) [1].
While EST3 required creating and compiling rules files, the EST4 features a context-sensitive Intellisense rule editor that checks for syntax and semantic errors in real time (Page 4) [1].
| Feature | EST3 Workflow | EST4 Workflow |
|---|---|---|
| Interface | Manual look-up lists/tables (Page 14) [1] | Graphical tree view (Page 4) [1] |
| Rule Editing | Manual file creation and compilation (Page 2) [1] | Real-time Intellisense rule editor (Page 4) [1] |
| Connectivity | RS232-to-USB dongles and special cables (Page 4) [1] | Direct high-speed USB (480 Mbps) (Page 4) [1] |
| Downloads | Multiple individual downloads | Single firmware and database download (Page 4) [1] |
| System Impact | May interrupt operation | No compromise or interruption to operation (Page 4) [1] |
EST4 download times are a fraction of those required by previous systems, and configuration data can be exchanged while the system remains fully functional, logging events and executing programming throughout the process (Page 4, 7) [1].
