5. Setup
5.1 Installazzjoni Fiżika
The NPort IA5250A-T can be mounted on a DIN-rail or wall-mounted.
- Immuntar tal-Ferrovija DIN: Attach the DIN-rail mounting kit to the back of the device. Securely clip the device onto a standard DIN-rail.
- Immuntar tal-ħajt: Use the provided wall-mounting plates (if applicable) to secure the device to a flat surface using screws.
5.2 Konnessjoni tal-Enerġija
Connect a compatible DC power source (typically 12-48 VDC) to the terminal block located at the top of the device. Ensure correct polarity. The device features power input redundancy for enhanced reliability.
5.3 Konnessjoni tan-Netwerk
Connect one or both 10/100BaseT(X) Ethernet ports to your network switch or router using standard Ethernet cables. The device supports auto MDI/MDI-X, so straight-through or crossover cables can be used.
5.4 Konnessjoni ta' Apparat Serjali
Connect your serial devices (e.g., PLCs, sensors, meters) to the DB9 serial ports on the NPort IA5250A-T. Ensure the correct pin assignments for RS-232, RS-422, or RS-485 are used. Refer to the device's pinout diagram in the detailed product documentation for specific wiring instructions.
5.5 Konfigurazzjoni Inizjali
After physical installation and power-up, the device can be configured via a web browser or MOXA's NPort Windows utility.
- Web Konsola: Iftaħ a web browser and enter the device's default IP address (refer to the Quick Installation Guide or product documentation for the default IP). Log in with the default username and password.
- NPort Windows Utility: Install the NPort Windows utility on a PC connected to the same network. The utility can discover the device and allow for configuration.
Configure network settings (IP address, subnet mask, gateway), serial port parameters (baud rate, data bits, parity, stop bits), and operation modes (e.g., Real COM, TCP Server, TCP Client, UDP).
6. Istruzzjonijiet Operattivi
6.1 Indikaturi LED
The NPort IA5250A-T features several LED indicators to display its status:
- PWR1/PWR2: Indicates power status for redundant power inputs. Lit when power is supplied.
- Lest: Lit when the device is powered on and operating normally.
- LAN Link/Act: Indicates Ethernet link status and activity.
- Serial Tx/Rx: Flashes to indicate data transmission (Tx) or reception (Rx) on the respective serial port.
6.2 Komunikazzjoni tan-Netwerk
Once configured, the NPort IA5250A-T facilitates communication between your serial devices and network applications. Depending on the configured operation mode, serial data can be transmitted over TCP/IP or UDP/IP.
6.3 Serial Port Modes
The device supports various serial port operating modes, including:
- Modalità COM reali: Allows Windows/Linux hosts to access serial devices over Ethernet as if they were directly connected to a local COM port.
- TCP Server/Client Mode: Establishes TCP connections for data exchange.
- Modalità UDP: Uses UDP for connectionless data transmission.
- Pair Connection Mode: Creates a transparent serial-to-serial connection over Ethernet between two NPort devices.
7. Manutenzjoni
