PART 1 INTRODUCTION 1.1 Safety and EMC Considerations This device is marked with the international caution symbol. It is important to read this manual before installing or commissioning this device as it contains important information relating to Safety and EMC (Electromagnetic Compatibility). This instrument is a panel mount device protected in accordance with EN 610101:2001, electrical safety requirements for electrical equipment for measurement, control and laboratory.
1.2 Description This iServer board can be purchased as a stand alone unit, or as an option for an iLD monitor/controller (Embedded Ethernet iServer) with a RS485 communication port interface. Some iLD Big Display monitors/controllers do not utilize RS485 communications. In such models, the RS485 instructions do not apply. The Embedded Ethernet Server is designed to connect industrial devices with serial interfaces to the Ethernet network using the TCP/IP protocol.

2.4 Serial Communication Interfaces (For Models with RS485 Port) The iLD Big Display controller/monitor with the Embedded Ethernet Server option board support only RS485/422 interfaces. These standards define the electrical characteristics of a communication network. The RS485 port of the Ethernet Server is fully compatible for use with RS422 instruments.
2.4.1 Wiring RS485 Interface RS485 interface uses a two-wire communication system (one for transmitting and one for receiving) plus a common wire to connect to the shield of the cable. It is recommended to use a shielded cable with one twisted pair. Use of twisted pair and shield will significantly improve noise immunity. Figure 2.3 shows multi-point, half-duplex RS485 interface connections for the iServer. GND ......................... -Tx/-Rx +Tx/+Rx -Tx/-Rx +Tx/+Rx 1 2 3 GND DEVICE #1 ............
2.5 Network Communication Interfaces 2.5.1 10Base-T RJ-45 Pinout The 10BASE-T Ethernet network (RJ-45) system is used in the iServer for network connectivity. The 10 Mbps twisted-pair Ethernet system operates over two pairs of wires. One pair is used for receiving data signals and the other pair is used for transmitting data signals. This means that four pins of the eight-pin connector are used.
PART 3 NETWORK CONFIGURATION 3.1 Network Protocols The iServer can be connected to the network using standard TCP/IP protocols. It also supports ARP, HTTP (WEB server), DHCP, DNS and Telnet protocols. 3.2 Ethernet (MAC) Address MAC (Media Access Control) address is your computer's unique hardware number. When you're connected to the LAN from your computer, a correspondence table relates your IP address to your computer's physical (MAC) address.
3.3 DHCP DHCP, Dynamic Host Configuration Protocol enables individual computers or devices to extract their IP configurations from a server (DHCP server). If the DHCP is enabled on your iServer, as soon as the iServer is connected to the network, there is an exchange of information between DHCP server and the iServer. During this process the IP address, the Gateway address, and the Subnet Mask will be assigned to the iServer by the DHCP server.
3.5 IP Address Every active device connected to the TCP/IP network must have a unique IP address. This IP address is used to build a connection to the iServer’s serial port. Every computer using TCP/IP should have a unique 32-bit address. It is divided into two portions, the network ID and the host ID. For instance, every computer on the same network uses the same network ID. At the same time, all of them have a different host ID. For more details about the IP address see Appendix B. 3.5.
PART 4 OPERATIONS An industrial device with serial interfaces (PLC, CNC controllers, PC, Data Display Devices, etc.) can be connected to the serial port of the Web Server. 4.1 SERIAL INTERFACE CONFIGURATION - Communication Protocol A data communication protocol defines the rules and structure of messages used by all devices on a network for data exchange. A typical transaction will consist of a request to send from the MASTER followed by the response from one or more SLAVE devices.
Where: "*" is the selected Recognition Character. You may select any ASCII table symbol from "!" (HEX address "21") to the right-hand brace (HEX "7D") except for the caret "^", "A", "E", which are reserved for bus format request. "ccc" stands for the hex-ASCII Command Class letter (one of eleven given in Table 4.1), followed by the two hex-ASCII Command Suffix characters identifying the meter data, features, or menu items to which the command is directed.
4.4 OPERATIONS This iServer can be used and configured in several ways, depending on user’s preference and network setup. It can be used in Telnet simulation mode where it emmulates serial communication operation over a network cable or directly from a Web browser, like Netscape or Internet Explorer.

If you want to change the time interval of the page refresh, enter the amount of seconds in the box. 000 092.4 Deg.C Auto Update Click on Device No.
4.5.3 Device Setup • Device Setup helps you to see eight different variables or devices by “Check” box. • Up to four different devices or parameters can be modified. • Device Address or ID is in Hex format. See Appendix D for conversion. DEVICE SETUP Address http://192.168.1.200 DEVICE SETUP No.
4.5.4 Configuration • This section explains the Configuration page of the iServers’s Web interface. • When connecting your device to the iServer, the Serial Communications parameters must match, between the iServer and your serial device. CONFIGURATION Address http://192.168.1.
4.5.4.A Serial Communication (continued) Transceiver: Can either be set to RS-232 or two-wire RS-485 (default is RS-485.) Modbus/TCP: A widely used protocol mainly in industrial automation applications with default TCP port number of 502 (see Local Port field). The options are Enable and Disable. If enabled, the Modbus/TCP is the only protocol driven by the iServer on its LAN port. If disabled, the TCP/IP is the only protocol driven by the iServer on its LAN port (default is disable).
4.5.4.B Terminal Server (continued) Connection Control: Some serial devices accept connections or disconnect connections based on certain signal conditions. For example, a serial device may accept a connection only if the incoming DTR signal (connected to device’s DSR or DCD) is high or low. In this case, when the iServer receives the TCP connection, before it forwards it to its serial port, it must raise its DTR (DTR+) or to lower its DTR (DTR-).
4.5.5 Access Control This section describes the "Access Control" page of the iServers’s Web interface. This page allows the users to set up the network and security parameters of the iServer. To get into the Access Control page, the user will be prompted with an Administrator Password. The default Admin password is 00000000 and is changeable, if desired. At the initial entrance to the “Access Control” page you will be prompted for the Login Password (see Figure 4.4) prior to an Administrator Password.
4.5.5 Access Control (continued) Host Name: Refer to Section 3.4, DNS. MAC Address: This is also called Hardware address or Ethernet address, which is assigned to the iServer at production. The MAC (Media Access Control) address is the iServer’s unique hardware number and is not changeable. IP Address: The IP (Internet Protocol) address is a 32-bit number that identifies each sender or receiver of information that is sent in packets across the Ethernet or the Internet.
4.6 Setting a New IP Address over the Network The iServer is shipped with a default IP address of 192.168.1.200 and Subnet Mask of 255.255.255.0. You can configure your PC’s Network connection with an IP address that is in the same range as the iServer’s IP address (192.168.1.x) and connect to the iServer using a crossover network cable between your PC and the iServer. With this completed, you can go to the DOS-Prompt and ping 192.168.1.200. If you receive responses back (similiar to Figure 4.
4.7 Terminal Server Function It is used to provide dedicated connectivity between computers and serial devices through the iServer over the Ethernet, without dedicated wiring. The typical Internet protocol consists of a request and a replay to that request. In this situation the server is the Host that generates the request and receives the replay from the device, that gets forwarded to the appropriate party on the network.
4.8 Terminal Emulation On this page you can send and receive data to and from the instrument. Simply, type the command in the open window and as you type the characters, the characters will be transmitted out from the serial port of the iServer. If the command is more than one character, you must type the command in a different window and then use “copy” and “paste” options to drop the command in the Terminal Emulation window (the right mouse button will give you “copy” and “paste” options).
4.9 Telnet Setup Telnet stands for Telecommunications Network, is a protocol that provides a way for users (or clients) to connect to computers (or servers) on a network, whether in the next building or across the other side of the world. You can open a Telnet session using other terminal emulation programs like Tera Term Pro (downloadable from the internet), which is a free software for MS-Windows. It supports VT100 emulation, Telnet connection and serial port connection.
4.9 Telnet Setup (continued) In the Configuration mode you can make any changes just like you would do using the Web Browser. After connected to the iServer, the user can use the following commands to read, modify, and get help from the iServer console. ? Following with a return character, the console will show all the commands and options (Figure 4.17). p Following with a return character, the console will show the iServer configurations (Figure 4.16).
4.10 HTTPGET Program You can setup and read the information from the iServer by using the HTTPGET program. The following program can be used to read data from the embedded server firmware by using TCP port 1000. The command string sends to this TCP port, then it reads back the response from the same port. Whatever you write to the port goes to the serial port unmodified. Any response from the serial port can be read back from the same socket. The Httpget.
4.11 ARP Protocol ARP is the Internet layer protocol responsible for determining the MAC (hardware) address that corresponds to a particular IP address. The ARP command allows the user to view the current contents of the ARP cache of the local computer (residing on the same network) or remote computer (residing on the different network) through a router. Microsoft includes the ARP.EXE utility for viewing and modifying the ARP cache with its Windows products.
4.12 Remote Access (Tunneling) To "tunnel", in this context, is to transmit data between two points through a private conduit on a shared or public network. The network could be an Ethernet LAN, a WAN, or the Internet. The iServer allows for a connection between a serial device and a PC, or between two serial devices, using an existing network rather than dedicated wiring.
4.12.1 Remote iServer It’s recommended to configure the Remote iServer and have it up and running before the Local iServer is configured. 1. A static IP address must be assigned to the Remote iServer. This means that the DHCP must remain disabled. Refer to the DHCP section of the user’s manual for details. 2. Use a browser to access the Remote iServer’s WEB page. Simply type the iServer’s IP address at the browser’s URL location (i.e. 192.168.1.50) followed by an Enter key.
4.12.2 Local iServer 1. An IP address should be assigned to the iServer dynamically or statically (recommended). 2. Use a browser to access the Local iServer’s WEB page. Simply type the iServer’s IP address at the browser’s URL location (i.e. 192.168.1.49) followed by an Enter key. You should then see the iServer’s main WEB page. 3. Click on the Update button. 4. Click on Configuration, you will be prompted with a Password (default is 12345678). 5.
4.13 Mail Notifier Software The Mail Notifier Software can be used only with NEWPORT Electronics instruments. For complete information of how to use the Mail Notifier software, click on the Help menu of the main window. The Mail Notifier software generates email notifications for alarm conditions. Users can be notified automatically of alarm conditions monitored via internet connections throughout the world.
4.13.2 Program Options Setup and Configuration Complete program setup requires: • Entering a recipient for the email • Specifying connection details to MAPI services. • Defining alarms for devices, and selecting how and when the email will be active. Figure 4.24 iServer Mail Notifier Profile Setup The “Send To” tab contains a field to specify an email address to which alarm notifications will be sent (i.e. the recipient). Only one entry is permitted, in the address field.
4.12.3 Device Setting and Configuration Device setup requires: • Entering the IP address for iServer device (for example 192.168.1.200). • Specifying Socket number (1000 or 2000 depending on iServer settings). • Defining RS485 Unit # interface address (1 to 199). Enter "0" for RS232 interface or for iServer. • Entering Reading command. Normally set to X01 to obtain reading from the devices. If you want to change this setting, refer to HTTPget Section 4.10.

APPENDIX A GLOSSARY User of this manual should be familiar with following definitions: ARP (Address Resolution Protocol) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address that is recognized in the local network. For example, the IP address in use today is an address that is 32-bits long. In an Ethernet local area network, however, addresses for attached devices are 48-bits long.
Appendix B IP Address An IP address is a unique 32-bit address assigned to a computer and includes: • A network ID number identifying a network. • A host ID number identifying a computer on the network. All IP addresses have been divided into three smaller groups (classes) A, B and C • Class A addresses have 8-bits of network ID and 24-bits of host ID. They can support a large number of hosts, approximately 2 = 16,777,216 computers per network. The IP addresses range in binary from 00000001.xxxxxxxx.
Appendix C IP Netmask IP Netmask or Subnet Mask is a 32-bit pattern of ones and zeros used to determine network portion of an IP address from the host portion of the IP address. Subnet mask is a network ID that is created by borrowing bits from host portion of IP address and using them as part of a network ID. The table below shows a default subnet mask for address Classes A, B, and C.
