### 4. Functionality

Operational Concept:
The NPort-5610-16 acts as a bridge between Ethernet and serial interfaces, encapsulating serial data into TCP/IP packets for transmission over Ethernet networks. It allows remote hosts to access serial devices as if they were directly connected to local COM ports.

Primary Use Cases:
- Industrial automation and SCADA systems
- POS and kiosk systems
- Building management and access control
- Remote monitoring of sensors, PLCs, and meters
- Serial console management for routers and switches
- Legacy equipment integration into IP networks

Compatibility:
- Operating Systems: Windows 95/98/ME/NT/2000/XP, Linux (Real TTY driver)
- Software Integration: Compatible with Moxa PComm Lite Serial Control Library for custom applications.
- Network Integration: Works with LAN, WAN, and Internet connections.

Operation Modes:
1. Host-Based / Driver Mode: Creates virtual COM ports on the host PC for transparent serial communication.
2. Pair Connection Mode: Links two NPorts to extend serial communication over Ethernet.
3. TCP Server Mode: Waits for incoming TCP connections from clients.
4. TCP Client Mode: Initiates TCP connections to remote servers.
5. UDP Server/Client Mode: Enables fast, connectionless data transmission and multicast support.
6. Ethernet Modem Mode (for Express models): Emulates modem behavior for legacy systems.
