### 4. Functionality

The iLOG101 functions as an IP-to-serial converter and data logger, enabling transparent communication between Ethernet networks and serial devices. It converts RS232 signals to RS422/RS485 and vice versa, while simultaneously allowing remote monitoring and data capture through virtual COM ports.

Operational Flow:
- Data from the RS232 port is converted to RS422/RS485 and transmitted to the connected device.
- The same data is mirrored to a virtual COM port on a remote PC for monitoring.
- Data from the RS422/RS485 port is converted back to RS232 and sent to the RS232 device, while also being logged to a second virtual COM port.
- Remote PCs can send data through virtual COM ports to trigger communication on either serial interface.

Use Cases:
- Industrial automation and control systems
- PLC communication monitoring (e.g., Siemens S7-200 via RS485)
- SCADA and HMI systems requiring remote serial data access
- Serial communication troubleshooting and diagnostics
- Data logging for process analysis and maintenance
- Remote simulation of serial devices for testing and validation

Compatibility:
- Windows NT/2000/XP/Vista/7 (virtual COM driver)
- Linux (raw TTY driver)
- SCO UNIX (real TTY driver)
- Compatible with RAYON’s RAYREAL monitoring software for dual-port data visualization and analysis
