    3. Initial IP Configuration Overview This chapter presents several ways to assign the NPort’s IP address for the first time. Please refer to Chapter 2 for instructions on connecting to the network. The web console is the recommended method for configuring the NPort. Please refer to Chapter 5 and 6 for details on using the web console for configuration.

  • Page 15: Using The Serial Console To An Assign Ip Address

    Using the Serial Console to an Assign IP Address Before using the NPort’s serial console, turn off the power and use a serial cable to connect the NPort console port to your computer’s serial port. Port 1 on the NPort serves as the console port. Use Port 1 connecting to the console port with a serial-based terminal or terminal emulator program, such as Windows HyperTerminal.
  • Page 16 In your terminal emulator program, set the terminal type to ANSI or VT100. If you select Dumb Terminal as the terminal type, some of the console functions—especially the “Monitor” function—may not work properly. Hold the grave accent key (`) down and power up the NPort. The continuous string of grave accent characters triggers the NPort to switch from data mode to console mode.

  • Page 17: Introduction To Operation Modes

    4. Introduction to Operation Modes Overview This chapter introduces the different serial port operation modes that are available on the NPort W2150A- W4/W2250A-W4 Series. Each serial port on the NPort is configured independently of the other ports, with its own serial communication parameters and operation mode. The serial port’s operation mode determines how it interacts with the network, and different modes are available to encompass a wide variety of applications and devices.

  • Page 18: Rfc2217 Mode

    Real COM mode allows you to continue using your serial communications software to access devices that are now attached to your NPort device server. On the host, the NPort Real COM driver automatically intercepts data sent to the COM port, packs it into a TCP/IP packet, and redirects it to the network. At the other end of the connection, the NPort device server accepts the Ethernet frame, unpacks the TCP/IP packet, and sends the serial data to the appropriate device.

  • Page 19: Udp Mode

    UDP Mode UDP is similar to TCP but is faster and more efficient. Data can be broadcast to or received from multiple network hosts. However, UDP does not support verification of data and would not be suitable for applications where data integrity is critical.

  • Page 20: Reverse Terminal Mode

    Reverse Terminal Mode Reverse terminal applications are similar to terminal applications, as they use the NPort W2x50A-W4 to manage the connection between a terminal and a server. The difference is that with reverse terminal applications; the terminal is connected through the network and the server is connected through the serial port, rather than the other way around.

    Verify the installation parameters and click Install to proceed. The wizard will begin installing the files. After the files have been installed, click Finish to complete the installation. Finding NPort Device Servers on a Network You can use the Device Search Utility (DSU) to look up or change the IP address of any NPort device server on the network.

  • Page 24: Modifying Nport Ip Addresses

    The utility will search for NPort device servers. When the search is complete, the NPort units that were found will be listed in the main window. Unlock Device Servers Select the device and click Un-Lock. Enter password and click OK. Modifying NPort IP Addresses Once the Device Search Utility (DSU) has found NPort device servers on the LAN, you can change any unit’s IP address.

  • Page 25: Upgrading Nport Firmware

    Enter the new IP address and netmask. If multiple units were selected, you may assign addresses sequentially by clicking Assign IP Sequentially. Click OK to proceed. The selected NPort will be restarted by the Device Search Utility (DSU) with the new IP address. Upgrading NPort Firmware Once the Device Search Utility (DSU) has found NPort device servers on the LAN, you can upgrade any unit’s firmware.
  • Page 26 Select the new firmware file and click OK to proceed. To get the latest firmware for the NPort W2150A- W4/W2250A-W4 Series, visit www.moxa.com.

  • Page 30: Adding Mapped Serial Ports

    The wizard will begin installing the files. When the files have been installed, click Finish to complete the installation. Adding Mapped Serial Ports NPort Windows Driver Manager adds a COM port to your PC that is mapped to an NPort serial port. The destination NPort serial port must be set to Real COM mode.
  • Page 31 Alternatively, you can select Input Manually and manually enter the NPort IP Address, 1st Data Port, 1st Command Port, and Total Ports for the desired NPort unit. Click OK to proceed. NPort Windows Driver Manager will list each available serial port and will automatically assign a new COM port to each one.

  • Page 32: Configuring Mapped Serial Ports

    Activated COM ports will be listed in black; COM ports that have not been activated will be listed in blue. Once a COM port has been activated, the host computer will communicate with the new COM port as if it were physically attached. Since the COM mappings are stored in the host system registry, they will still be in effect if the PC is restarted or if Windows Driver Manager is closed.
  • Page 33 On the Basic Setting tab, select the COM Number that will be assigned to the serial port. If you have selected multiple ports, you can assign COM numbers automatically in sequential order by selecting the Auto Enumerating COM Number for Selected Ports function. On the Advanced Setting tab, configure Tx Mode, FIFO, and Fast Flush.
  • Page 34 Auto Network Re-Connection: With this option enabled, the driver will repeatedly attempt to re- establish the TCP connection if the NPort does not respond to background “check-alive” packets Always Accept Open Requests: When enabled, the NPort driver will always accept requests to open a virtual COM port, even if communications with the device can not be established.
  • Page 35 On the Security tab, select the Enable Data Encryption option to enable data to be encrypted when transmitted over the COM ports. After selecting the encryption option, select the Keep connection option to encrypt COM port communications immediately without restarting the COM ports. This may speed up opening and closing of the COM port for your host, but it also causes your host to tie up the NPort serial port so other hosts cannot use it.
  • Page 36 To save all COM mapping settings to a text file, right-click a COM port and select Export in the context menu. After the settings have been exported to a file, they can be imported on another host. NPort W2150A-W4/W2250A-W4 Series User Manual...
