### 4. Functionality

The IES‑1142P functions as an unmanaged Layer 2 Ethernet switch, automatically learning and forwarding Ethernet frames between connected devices. It supports auto‑negotiation for speed and duplex mode and auto MDI/MDI‑X for cable type detection, eliminating the need for crossover cables.

Typical Use Cases:
- Industrial automation networks connecting PLCs, HMIs, and Ethernet I/O modules.
- IP surveillance systems linking IP cameras and NVRs.
- Transportation and traffic control systems requiring reliable field communication.
- Energy and utility monitoring networks.
- Remote monitoring and control in harsh outdoor or factory environments.

Compatibility:
- Compatible with standard Ethernet devices such as PCs, servers, routers, and other switches.
- Supports both copper (UTP) and fiber‑optic connections via SFP transceivers.
- Works with Cat 3, 4, 5, or 5e UTP cables for 10/100 Mbps links (maximum 100 m per segment).

Operation Principle:
Data packets are received on one port, stored briefly in memory (store‑and‑forward), checked for errors, and then forwarded to the appropriate destination port based on MAC address learning. The unmanaged design ensures zero configuration and immediate network integration.
