E5810 Description E5810 Software/Firmware E5810 Software/Firmware The E5810 LAN/GPIB Gateway for Windows provides an interface (gateway) that allows networked computers to talk or listen to GPIB and/or RS-232 devices via Local Area Network (LAN) connections. The E5810 connects a network (Enterprise or Local) from PCs with Windows 98/2000/NT/Me/XP Professional to GPIB and/or RS-232 instruments.
E5810 Description E5810 Software/Firmware E5810 Operating Features Feature Description Remote access to instruments via LAN Access and control up to 14 GPIB and/or one RS-232 instrument via a 10BASE-T/100BASE-TX Ethernet. The E5810 detects the network and configures itself to the appropriate speed. The E5810 has a standard RJ-45 LAN connector. You can use adapters to connect other interface types, such as optical or wireless LAN.
E5810 Description E5810 Software/Firmware Typical Network Operation The E5810 provides a network gateway between network-equipped computer systems and GPIB and/or RS-232 based instruments. The Gateway enables users to obtain measurement data either locally or remotely from GPIB and/or RS-232 instruments. See “Typical Network Connections” in this chapter for typical connections to Enterprise or Local Networks or to a PC.
E5810 Description E5810 Software/Firmware Software/Firmware Architecture To program instruments from your PC via the E5810 using a programming language such as C or Visual Basic, you must install and configure the Agilent IO Libraries on the client PC. Client System Architecture As shown in the following figure, the client system contains the VISA LAN client software as well as the TCP/IP LAN software needed to access the E5810.
E5810 Description E5810 Software/Firmware How IO Application Software Works With the E5810 Before trying to perform an I/O application operation on the E5810 GPIB interface and the GPIB bus, the LAN client software in the client computer system establishes a network connection to the LAN server (the E5810). Once the client establishes a connection, the client can begin to send I/O requests to the E5810. The E5810 (LAN server) can have multiple clients connected and being serviced at any given time.
E5810 Description E5810 Software/Firmware Typical Network IP Addressing This section describes typical Enterprise network IP addresses and subnet addresses on the network. This figure shows a typical Enterprise network, consisting of a Router (Gateway), a corporate Dynamic Host Configuration Protocol (DHCP) Server, and a subnet consisting of six hosts (two E5810s and four host PCs.) The Router sends packets of information to each host, based on the IP address of the host.
E5810 Description E5810 Software/Firmware Subnet Addressing A Subnet Mask is used to determine to which subnet an IP address belongs. An IP address has two components: the network address and the host address. For example, assuming IP address 156.215.117.109 is part of a Class B network, the first two numbers (156.215) represent the Class B network address and the second two numbers (117.109) identify a specific host on this network. See the Glossary for a description of a Class B network.
E5810 Description E5810 Software/Firmware Communicating with the E5810 There are two ways you can communicate with the E5810 via a network: use the E5810 Web access or use a supported programming language with the Agilent IO Libraries.

Troubleshooting Information Checking the Network Checking the Network If the E5810 is correctly installed and configured and is operational, the next step is to check the network installation and configuration. To do this step, you may need the help of your System Administrator. This section gives guidelines to check your network.
Troubleshooting Information Checking the Network Checking Web Browser Settings The E5810 Web access (web server) generates web pages that depend on Javascript and Frames. You can use any web browser that supports these features to view and interact with the E5810 web server. For best results, you may need to Enable Javascript, and configure Cache and Page Refresh, and/or Proxies options on your Web browser. Internet Explorer 5.5 or later or Netscape Navigator 6.2 or later are recommended.
Troubleshooting Information Checking the Network Cache and Page Refresh For faster performance, most web browsers cache web pages. If a page is cached, an image of the web page is stored locally. When you navigate to a page that has already been viewed, the browser will load the page from it cache rather than loading it from the network. Usually, this process works well for static web pages. However, this process may cause problems for 'dynamically' changing web pages.

Using the Telnet Utility Telnet Commands for the E5810 Notes: 160 Appendix C
Glossary 161
Glossary A address A string uniquely identifying a particular interface or a device on that interface which is interpreted at the E5810 LAN/GPIB Gateway to identify the interface or device. ASRL For the E5810, ASRL is synonomous with RS-232. See RS-232. B Bridge C client In telecommunication networks, a bridge is a product that connects a local area network (LAN) to another local area network that uses the same protocol (for example, Ethernet or token ring).
Glossary D device A unit that receives commands from a controller. Typically a device is an instrument but could also be a computer acting in a non-controller role, or another peripheral such as a printer or plotter. DHCP Short for Dynamic Host Configuration Protocol, a protocol for assigning dynamic IP addresses to devices on a network. With dynamic addressing, a device can have a different IP address every time it connects to the network.
Glossary F Friendly Name G gateway The "UPnP Friendly Name" of the E5810 that will automatically be displayed on Universal Plug and Play (UPnP) enabled LAN hosts. When the E5810 is connected to the LAN, it broadcasts its presence to the network if UPnP is enabled. UPnP clients will then see the name and description of this E5810 in My Network Places. A Friendly Name can be up to 39 characters including spaces.
Glossary - Intelligent hubs include additional features that enables an administrator to monitor the traffic passing through the hub and to configure each port in the hub. Intelligent hubs are also called manageable hubs. - Switching hubs actually read the destination address of each packet and then forward the packet to the correct port. I instrument A device that accepts commands and performs a test or measurement function.
Glossary L LAN Local Area Network. A computer network that spans a relatively small area. Most LANs are confined to a single building or group of buildings. However, one LAN can be connected to other LANs over any distance via telephone lines and radio waves. A system of LANs connected in this way is called a wide-area network (WAN). Most LANs connect workstations and personal computers.
Glossary N network protocols The E5810 supports these network protocols: ARP, DHCP, DNS, FTP, HTTP, ICMP, and RPC. ARP: Short for Address Resolution Protocol, a TCP/IP protocol used to convert an IP address into a physical address (called a DLC address), such as an Ethernet address. DHCP: See DHCP DNS: See DNS FTP: Abbreviation of File Transfer Protocol, the protocol used on the Internet for sending files. HTTP: Short for HyperText Transfer Protocol, the underlying protocol used by the World Wide Web.
Glossary Instead of forwarding the request to the Web server where Page 1 resides, which can be a time-consuming operation, the proxy server returns the Page 1 it already fetched for user X. Since the proxy server is often on the same network as the user, this is a much faster operation. Real proxy servers support hundreds or thousands of users. Filter Requests: Proxy servers can also be used to filter requests.
Glossary SRQ Service Request. An asynchronous request (an interrupt) from a remote device indicating that the device requires servicing. Subnet A portion of a network that shares a common address component. On TCP/IP networks, subnets are defined as all devices whose IP addresses have the same prefix. For example, all devices with IP addresses that start with 100.100.100. would be part of the same subnet. Dividing a network into subnets is useful for both security and performance reasons.
Glossary Switch A device that filters and forwards packets between LAN segments. Switches operate at the data link layer (layer 2) and sometimes the network layer (layer 3) of the OSI Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub connects all the devices on its "ports" together.
Glossary The E5810 has two options for Universal Plug and Play (UPnP): Option ON: The E5810 is configured as a UPnP device and provides information to the network about itself via an XML description when mounted to the network. Option OFF: The E5810 is not UPnP capable and will not announce its presence as a UPnP device when mounted to the network. V VEE The Agilent Visual Engineering Environment, which is software used for I/O application programming.
