### 2. Key Features

- Four RS232 Serial Ports:
Each port uses a DB9 male connector and supports data rates up to 230,400 bps.
Each port provides 5V power output on pin 9, suitable for powering external devices such as barcode readers.

- Embedded Linux System:
The internal system runs on a 32-bit 100 MHz MIPS CPU with 16 MB Flash ROM and 16 MB SDRAM, ensuring stable multitasking and network performance.

- Ethernet Connectivity:
Auto-detecting 10/100 Mbps Ethernet interface (RJ45) supporting both 10Base-T and 100Base-TX standards.

- Flexible Network Protocols:
Supports TCP/IP and UDP/IP communication modes, including TCP Server, TCP Client, and UDP Send/Receive modes.

- Cross-Platform Driver Support:
- Windows NT/2000/XP/Vista/7/8/10: Virtual COM port driver (TPORT or RPORT).
- Linux: Raw TTY driver (GVMODEM).
- SCO UNIX: Real TTY driver (RTTY).

- Web, Telnet, and Console Configuration:
Multiple setup interfaces for network and serial configuration, including firmware upgrade and diagnostic tools.

- Integrated Power Output Control:
Each RS232 port provides a 5V output on pin 9, controlled via the DTR signal.
A special variant (IPORT104P1) provides continuous 5V output regardless of DTR state.

- Current Limitation Protection:
Built-in current limiting circuit prevents overload or short-circuit damage on the 5V output pins.

- Compact Industrial Design:
Durable enclosure with dimensions 205 × 135 × 29 mm, optimized for panel or desktop installation.

### 4. Functionality

The IPort104P functions as an IP-to-Serial converter, bridging Ethernet-based communication with up to four RS232 serial devices. It enables remote access, monitoring, and control of serial equipment over LAN or WAN networks.

Operating Modes:
1. TCP Server Mode:
The device listens for incoming TCP connections on assigned ports. Ideal for applications where remote clients initiate communication.
2. TCP Client Mode:
The IPort104P initiates a connection to a predefined server IP and port, suitable for centralized data collection.
3. UDP Mode:
Supports both send and receive operations, allowing broadcast or multicast communication to multiple hosts.
4. Real TTY Mode (UNIX/Linux):
Provides fixed pseudo-terminal mapping for direct serial access.
5. Virtual COM Mode (Windows):
Emulates standard COM ports via TPORT or RPORT drivers, enabling legacy software to communicate transparently over IP.

Configuration Interfaces:
- Web Interface: Browser-based configuration (default IP: 192.168.1.254, password: 11111).
- Telnet Interface: Command-line configuration and diagnostics.
- Console Port: Accessible via serial port 1 when DIP switch is set to console mode.

Applications:
- Barcode readers and scanners
- Industrial automation controllers
- POS systems and kiosks
- Remote sensor monitoring
- Serial-based instrumentation
- Legacy serial device networking

Compatibility:
- Windows (NT through Windows 10)
- Linux and UNIX systems
- SCO OpenServer
- Compatible with standard TCP/UDP socket applications and COM port emulation software.
