each other’s MAC address to maintain point-to-point communication over the Internet. • IP Address This is a 4-byte (32-bit) number assigned to a network device for communicating over an Ethernet. Depending on how a device connects to the network (over a LAN, via modem to an ISP’s server, etc.) the IP address may not be fixed. • Port Number A TCP connection or UDP datagram is defined by a destination IP address and port number.
2 Getting Started Now that you have been introduced to NPort Express's features and specifications, it’s time to install the hardware and get your system up and running. We begin this chapter with a brief explanation of the three general types of operation mode available when using NPort Express. The setup procedure is somewhat different for each operation mode; so first take the time to determine which application best suits your needs.
rial devices from a distance, either over a LAN, or even over the Internet. In this section, we discuss three types of application—Host-Based Mode, Pair-Connection Mode, and Raw-Connection Mode. Read carefully to determine which application best suits your needs. Host-Based Mode Traditional serial port communication uses a COM port board that slides into one of the slots on the back of your PC. In this case, only the computer containing the board has direct access to the board’s s erial port.
Hardware Installation In the previous section, we introduced the three general operation modes of NPort Express. This section describes briefly how to connect NPort Express to your serial device, how to hook up the power cable, and how to connect to the Ethernet. Serial Connection NPort Express has one DB9 serial port on the back panel. Depending on your s erial device and serial interfaces, there are two options: 1. You may use a DB9 to DB9 cable to connect your serial device to NPort Express.
to use a cross-over Ethernet cable, such as the one supplied with your server. The amber Link light will flicker when NPort Express is properly connected to a live Ethernet. DIP Switch Settings The top panel of NPort Express contains a table (shown below) describing DIP switch settings for the serial port. Serial Connection RS-232 ON Console Data OFF Comm.
Some setup procedures can be carried out through a Telnet connection, during which data is transmitted through NPort Express’s Ethernet port. However, you must set SW1 to OFF to establish a Telnet connection. IP Address Configuration You may choose from two different methods to configure the IP address assigned to your NPort Express. Note that NPort Express is shipped with the IP address set to the following by default: Default IP address: 192.168.127.
3. When the Telnet window opens up, type 1 to select ansi/vt100 for Console terminal type , and then press Enter. 4. A connection between your computer and NPort Express should now be established, and the MOXA NPort Express utility program will automatically start running. 5. To ensure proper operation, click on the Terminal menu, choose Preferences…, and then make sure VT100 Arrows is checked. .Note: Not choosing VT100 Arrows could result in inadvertently changing the server’s name and IP address. 6.
“display only” are not enclosed. 8. Since our goal in this section is to set the IP address of the server, use the keyboard arrow keys to position the cursor over the first digit of the IP address. Type in the correct IP address and then press Enter to accept this value. 9. Press ESC to return to the main menu, and then select Restart to activate the change. Direct Console You may also use NPort Express’s RS-232 Console function to set up the IP address.
4. When the PComm Terminal Emulator window opens up, first click on the Port Manager menu item and select Open, or simply click on the Open icon . 5. From the Property window’s Communication Parameter page, select the appropriate COM port for the connection, COM1 in this example, and 115200 for Baud Rate. 6. From the Property window’s Terminal page, select VT100 for Terminal Type.
7. Use the keyboard arrow keys to highlight [serverConfig] as shown below, and then press Enter to select this option. 8. A window showing the various parameters required to configure NPort Express opens up. Those parameters that are “configurable” are enclosed in square brackets, and those parameters that are “display only” are not enclosed. 9. Since our goal in this section is to set the IP address of the server, use the keyboard arrow keys to position the cursor over the first digit of the IP address.
Press ESC to return to the main menu, and then select Restart to activate the change. Depending on the way your computer and network are set up, you may find it convenient or even necessary to set up NPort Express over a network. This can be done using the Telnet program. In the following discussion, we assume you are using a Windows NT host. DHCP Configuration This section is applicable if you are using your Windows NT 4.0 host as a DHCP server, where DHCP stands for Dynamic Host Configuration Protocol.
2. The left side of the DHCP Manager window will show a list of DHCP hosts currently hooked up to the network. Note that before you can make changes to the host’s parameters, there must be a minus sign (-) located to the left of the server name (Local Machine in the example shown below.) If, as shown below, there is a plus sign (+) to the left of the server name, use the left mouse button to click on the name until you see the minus sign appear. 3. You must now define the DHCP server “scope”.
5. Once the Create Scope (Local) window opens (see below), you will be required to input a range of IP addresses in the IP Address Pool . There is also an Exclusion Range used to prevent the DHCP server from issuing addresses to existing devices that have already been assigned IP addresses from this range. By using the Add and Remove buttons, several different ranges can be excluded, and later included. 6. Another item that must be attended to is the Subnet Mask.
9. A window opens with the question: Activate the new scope now? Click on Yes to activate. At this point we explain how to input a unique IP address reserved exclusively for use by your NPort Express. 10. From the DHCP Manager – (Local) menu bar, click on Scope , and then select Add Reservations. 11.
Comment. First, enter the selected IP address, and then locate and enter your NPort Express’s MAC address in the Unique Identifier field. (The MAC address is located on NPort Express’s back panel, or see Appendix B for an explanation of using NPort Express’s LCD buttons to locate the MAC address.) Be sure to enter the same Client Name that was entered in the Name field of the Create Scope - (Local) window (see step 8 above). The Client Comment is optional.
3 Installation and Configur a tion In the previous chapter we explained how to set up NPort Express for use on a network. In this chapter we explain how to configure the server for the particular application you have chosen.
