Safety Considerations

Product and Documentation Labels

A WARNING denotes a hazard that can cause injury or death. A CAUTION denotes a hazard that can damage equipment or cause data loss. Do not proceed beyond a WARNING or CAUTION notice until you understand the hazardous conditions and have taken appropriate steps.

Grounding

The power module (Agilent 0950-2546 AC/DC Adapter) is a safety class I product and has a protective earthing terminal. There must be an uninterruptible safety earth ground from the main power source to the product’s input wiring terminals, power cord, or power cord set. Whenever it is likely that the protection has been impaired, disconnect the power cord until the ground has been restored.

Servicing

There are no user-serviceable parts inside the E2050 LAN/GPIB Gateway or its power module (AC/DC Adapter). Any servicing, adjustment, maintenance, or repair must be performed by service-trained personnel only. The power module does not have a power switch. The power cord is intended to serve as the disconnect device. Make sure the power module is installed near a wall outlet and is easily accessible.

Radio and Television Interference

This device has been verified to comply with FCC Rules Part 15. Operation is subject to these two conditions: (1) this device may not cause radio interference, and (2) this device must accept any interference received (including interference that may cause undesired operation).

This equipment generates and uses radio frequency energy. If not installed and used in accordance with this manual, it can cause interference to radio and television communications. The rules with which it must comply afford reasonable protection against such interference when it is used in most locations.

However, there can be no guarantee that such interference will not occur in a particular installation. If you think your device is causing interference, turn off the system. If the radio or television reception does not improve, your device is probably not causing the interference.

7

If your device does cause interference to radio and television reception, you are encouraged to try to correct the interference by one or more of the following measures:

nRelocate the radio or TV antenna.

nMove the device away from the radio or television.

nPlug the device into a different electrical outlet, so that the device and the radio or television are on separate electrical circuits.

nMake sure you use only shielded cables to connect peripherals to your device.

nConsult your dealer, Agilent Technologies, or an experienced radio/ television technician for other suggestions.

nOrder the FCC booklet How to Identify and Resolve Radio-TV Interference Problems from the U.S. Government Printing Office, Washington, D.C. 20402. The stock number of this booklet is 004-000-00345-4.

Typical LAN Connections

The E2050 LAN/GPIB Gateway combines hardware and firmware in a single box that provides a network gateway between network-equipped computer systems and GPIB based instruments. The Gateway enables users of I/O applications to obtain measurement data either locally or remotely from GPIB instrumentation. The following figure shows typical LAN connections for an E2050 Gateway.

Introduction

E2050 Software/Firmware Architecture

The Gateway connects the local area network (LAN) from the computer system to the GPIB bus. Network-equipped computer systems that are supported for use with the Gateway include Series 700 workstations and 32-bit PCs. Following the client/server model of computing, the computer system is the client, and the E2050 LAN/GPIB Gateway acts as the server.

Client - Server Configuration

Thus, I/O applications running on the computer system can transparently interface to GPIB-based instruments over the LAN. Since several computer systems can access the LAN/GPIB Gateway, groups of users can share access to the same GPIB instruments via the Gateway. In addition, existing I/O applications that are supported with the LAN/GPIB Gateway and are designed for GPIB can use the Gateway without modification beyond an address change.

The Gateway and its attached GPIB instruments can be placed anywhere on the network (rather than with a particular controller or server computer system). This includes networks which span different geographic locations, such as when networked computer systems are located at several different sites. Hence, GPIB instruments can be located where they are most convenient for I/O application users.

In addition, you can have more than one LAN/GPIB Gateway on a network, providing “clusters” of GPIB instrumentation at different locations. This further aids users in accessing the instrumentation they need for their specific I/O applications.

Introduction

E2050 Software/Firmware Architecture

Software/Firmware Architecture Overview

Agilent SICL contains the LAN client software needed to access the LAN/GPIB Gateway. Thus, SICL is also provided with the VISA, VEE, and HP BASIC/UX 700 I/O application software products. To use any of these software products with the LAN/GPIB Gateway, you must also install and configure SICL on the client computer system.

Several of these software products support two different LAN networking protocols: the SICL LAN Protocol and the TCP/IP Instrument Protocol. Version A.01.00 or later of the LAN/GPIB Gateway supports the SICL LAN Protocol and VXI-11 (TCP/IP Instrument Protocol). To check your version of the Gateway (and the protocol(s) you can use with the Gateway depending on the software product you have), see Chapter 4.

As shown in the following figure, the client system contains the LAN client software provided with SICL as well as the TCP/IP LAN software needed to access the Gateway. The Gateway contains LAN server and TCP/IP LAN firmware so that it acts as the LAN server.

The LAN client software provided with SICL uses the TCP/IP LAN protocol suite to pass messages between the client system and the server (the E2050 LAN/GPIB Gateway). Therefore, the client sends I/O requests over the network to the server. The server then executes those I/O requests on the appropriate GPIB based instrument(s) connected to the server.

Introduction

E2050 Software/Firmware Architecture

Using Application Software

Establishing a

Network Connection

This section summarizes how the software on a client computer system works with the E2050 LAN/GPIB Gateway to complete I/O application operations on attached GPIB instruments. For more information on how to use your software with the Gateway, see the applicable software documentation as listed in “Related Software Documentation”.

Before trying to perform an I/O application operation on the Gateway’s GPIB interface and the GPIB bus, the LAN client software in the client computer system establishes a network connection to the LAN server (the Gateway). Once the client establishes a connection, the client can begin to send I/O requests to the Gateway.

Maximum Client

Connections

The Gateway (LAN server) can have multiple clients connected and being serviced at any given time. The maximum number of concurrent client connections depends on memory usage in the Gateway, including the number of clients and the number of current sessions running on those clients. However, at least 8, but not more than 15, client connections can be running concurrently. Thus, if the maximum number of client connections to the Gateway has not been exceeded, the connection is allowed to occur.

I/O Application

Operation

Using Locks

Although several instruments can be connected to the Gateway’s GPIB bus, only one I/O application operation can occur on the GPIB bus at any given time. Therefore, once a client’s request begins to execute on the GPIB, all other client requests for operations on the GPIB must wait until the current client request completes. Client requests are serviced in a first come, first served manner, unless they are prohibited by interface or device locks.

If a client has a sequence of I/O application operations to perform that should not be preempted, the client should obtain a lock on the Gateway’s GPIB interface or device. Once the client’s sequence has completed, it should release its lock, allowing other clients access.

Closing a Network

Connection

When a client closes a connection, the Gateway frees up the resources allocated to that client, including any locks, pending I/O requests, memory usage, etc. Abnormal termination (for example, the network and/or client goes down) is discussed in Chapter 5.

Installing the Hardware

This section shows how to install the LAN/GPIB Gateway hardware by connecting it to the LAN, GPIB bus, and power module.

Step 1: Record LAN Hardware Address

First, find the hardware address of the LAN interface in the E2050 LAN/GPIB Gateway. Turn the Gateway over and look for the label on the underside of the Gateway. The hardware address on the label will be similar to 0800XXXXXX. Write down this address, as you may need it later to configure the Gateway on the network.

CAUTION: Use only Agilent Technologies specified AC - DC adaptor.

CAUTION: No operator serviceable parts inside.

Refer servicing to qualified personnel.

POWER: Input: 5V DC, 6 watts

Step 3: Connect the Gateway to the Network

CAUTION

Do not connect to both the RJ-45 and the BNC connectors on the Gateway. Only one connection to the LAN interface in the Gateway can be made at a time. Data loss may occur if you try to use both connectors simultaneously. The Gateway will automatically select the active port.

NOTE

To connect the Gateway to a ThickLAN or fiber optic network, see the hardware documentation for with your ThickLAN or fiber optic network to connect the LAN cable to the RJ-45 connector on the Gateway.

To connect the Gateway directly to a client computer system, you will need a special twisted-pair cable. Contact Agilent Technologies for more information.

nEthertwist Connection. For Ethertwist, connect the LAN cable to the RJ-45 connector on the back panel of the Gateway.

Step 4: Connect GPIB Cable and Power Cords

NOTE

The power module and Gateway do not have power switches. Connecting the standard AC power cord to the power source (wall outlet) activates both units. The power module automatically adapts to the correct AC voltage range for your power source.

nConnect the GPIB cable from the GPIB instrument(s) to the GPIB connector on the back panel of the Gateway.

nConnect the DC power cord attached to the power module (AC/DC Adapter) to the power input on the back panel of the Gateway, as shown.

nConnect the standard AC power cord to AC IN on the power module and to a power outlet (wall outlet), as shown.
