### 4. Functionality

The PAC‑4010T functions as a compact embedded automation controller capable of running Linux‑based applications for industrial monitoring, data acquisition, and control. It boots from onboard NAND Flash, loads the Linux 2.6 kernel, and mounts the root file system automatically.

Typical Use Cases:
- Industrial process control and monitoring.
- Remote data logging and SCADA integration.
- Machine automation and equipment interfacing.
- Networked I/O gateway or protocol converter.
- Embedded web server for remote configuration.

Operation:
- Upon power‑up, the controller initializes the bootloader (uBoot), loads the kernel, and executes system initialization scripts from `/etc/inittab`.
- Users can access the system via Ethernet (SSH, Telnet, FTP, or HTTP) or through the serial console.
- The device supports both static and dynamic IP configurations and can be managed using Artila’s Java Manager utility.
- The built‑in web server (Lighttpd v1.7) hosts configuration pages located in `/usr/www`.

Compatibility:
- Supports USB WLAN adapters (Ralink RT2571) via `rt73usb` driver.
- Compatible with standard Linux utilities and third‑party software packages installed via `ipkg`.
- Works with GNU toolchains for cross‑compilation on Linux or Windows hosts.
