5. Setup

5.1 Physical Installation

The NPort IA5250A-T can be mounted on a DIN-rail or wall-mounted.

• DIN-Rail Mounting: Attach the DIN-rail mounting kit to the back of the device. Securely clip the device onto a standard DIN-rail.
• Wall Mounting: Use the provided wall-mounting plates (if applicable) to secure the device to a flat surface using screws.

5.2 Power Connection

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 Network Connection

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 Serial Device Connection

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 Initial Configuration

After physical installation and power-up, the device can be configured via a web browser or MOXA's NPort Windows utility.

• Web Console: Open 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. Operating Instructions

6.1 LED Indicators

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.
• Ready: 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 Network Communication

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:

• Real COM Mode: 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.
• UDP Mode: Uses UDP for connectionless data transmission.
• Pair Connection Mode: Creates a transparent serial-to-serial connection over Ethernet between two NPort devices.

7. Maintenance

7.1 Cleaning

Periodically clean the exterior of the device with a soft, dry cloth. Do not use liquid or aerosol cleaners. Ensure the device is powered off before cleaning.

7.2 Firmware Updates

Check the MOXA website regularly for firmware updates. Firmware updates can provide new features, performance improvements, and security enhancements. Follow the instructions provided with the firmware package for safe updating.

7.3 Environmental Considerations

Ensure the device operates within its specified temperature and humidity ranges. Avoid exposing the device to excessive dust, moisture, or direct sunlight.

8. Troubleshooting

If you encounter issues with your NPort IA5250A-T, refer to the following common troubleshooting steps:

• No Power: Check the power connections and ensure the power supply is functioning. Verify PWR1/PWR2 LEDs are lit.
• No Network Connectivity: Check Ethernet cable connections. Verify LAN Link/Act LEDs. Ensure network settings (IP address, subnet mask) are correct.
• Serial Communication Errors: Verify serial cable connections and pinouts. Check serial port parameters (baud rate, data bits, parity, stop bits) match the connected device. Ensure the correct serial operating mode is configured.
• Device Unresponsive: Try power cycling the device. If the issue persists, consider performing a factory reset (refer to the detailed product manual for reset procedures).
