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.
Agilent Virtual Instrument Software Architecture (VISA), VISA COM,
Standard Instrument Control Library (SICL), and several I/O utilities.
This standard software provides compatibility with different hardware
and software vendors. It provides the I/O software layer used when
accessing the E5810. Y ou can use a standard programming language,
such as Visual Basic, Visual C++, Agilent VEE, etc.
The E5810 supports all I/O application operations provided by VISA,
VISA COM, SICL, and Agilent VEE. The E5810 is supported on
Microsoft Windows 2000/XP/Vista.
You can also use the Agilent IntuiLink software (included with some
Agilent products) to download data and send waveforms to the source,
with no programming.
The E5810 supports Dynamic Host Configuration Protocol (DHCP) to
get its IP address. Although the E5810 defaults to using DHCP, you
can turn DHCP OFF and statically assign the E5810 IP address.
Ease of Use Built-in Web access and front panel display allow you to easily set up,
configure, and use the E5810. You can connect multiple E5810s in a
test system. Each E5810 creates a separate GPIB bus.

Typic al Net wor k Operat io n
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.
The E5810 connects a local area network (LAN) from the computer system
to the GPIB and/or RS-232 buses. Network-equipped computer systems
that are supported for use with the E5810 include PCs with Windows
2000/XP/Vista. Using the client/server model of computing, the computer
system is the
client, and the E5810 is the server.
Thus, applications running on the computer system can transparently
interface to GPIB and RS-232 based instruments over the LAN. Since
several computer systems can access the E5810, groups of users can share
access to the same GPIB and/or RS-232 instruments via the E5810. In
addition, existing I/O applications that are supported with the E5810 and are
designed for GPIB or RS-232 can use the E5810 without modification other
than an address change.
The E5810 and its attached 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.
Thus, GPIB and RS-232 instruments can be located where they are most
convenient. In addition, you can have more than one E5810 on a network,
providing “clusters” of GPIB and/or RS-232 instrumentation at different
locations.

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 Suite on the client PC.
Client System
Architecture
As shown in the following figure, the client (PC) system contains the VISA
LAN client software as well as the TCP/IP LAN software needed to access
the E5810. The E5810 contains LAN server and TCP/IP LAN firmware so it
acts as the LAN server .
The VISA LAN client software is also known as the Remote IO Client
software. It is part of the Agilent IO Libraries Suite. The LAN server software
is also called the Remote IO Server software.
The VISA LAN client software uses the TCP/IP LAN protocol suite to pass
messages between the client system and the server (the E5810). 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 and/or RS-232 based
instrument(s) connected to the server.
Chapter 1 27
E5810 Description
E5810 Software/Firmware
How IO Application
Softwar e Works
With the E5810
Before trying to perform an I/O application operation on the E5810 GPIB
interface and the GPIB bus, the Remote IO Client software in the client
computer system establishes a network connection to the remote I/O server
(the E5810). Once the client establishes a connection, the client can begin to
send I/O requests to the E5810.
The E5810 (remote I/O 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 E5810, including the number
of clients and the number of current sessions running on those clients.
However, up to 16 client connections can be running concurrently. Thus, if
the maximum number of client connections to the E5810 has not been
exceeded, the connection is allowed to occur.
Although several instruments can be connected to the E5810 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 E5810 GPIB
interface or device. Once the client’s sequence has completed, it should
release its lock, allowing access for other clients.
When a client closes a connection, the E5810 frees up the resources
allocated to that client, including any locks, pending I/O requests, memory
usage, etc.

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. The subnet is defined by the
Mask
for the IP addresses on the subnet.
E5810 Description
E5810 Software/Firmware
Subnet
Chapter 1 29
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.
For the subnet in the figure, an example IP address for E5810 #1 is
156.140.104.72, where 156.140 represents the network address and 104.72
represents the E5810 #1 host address. An example IP address for E5810 #2
is 156.140.104.75, where 156.140 represents the network address and
104.75 represents the E5810 #2 host address.
E5810 IP Address
Assignment
For the E5810 to operate on an Enterprise network, three addresses must
be identified: E5810 IP Address, Subnet Mask, and Default Gateway
Address.
If the Enterprise network supports Dynamic Host Configuration Protocol
(DHCP), the E5810 will automatically receive an IP address, Subnet Mask,
and Default Gateway from the DHCP Server. If the network does not support
DHCP, the E5810 IP address must be configured manually.
In addition, if the network supports Domain Name Service (DNS), an E5810
Hostname can be configured. This can be done in one of two ways:
The DNS Server IP Address is provided by the DHCP Server (this is
transparent to the user).
A DNS Server IP address is supplied by the System Administrator
and entered on the

What is a Local Network?
A local (peer-to-peer) network is a network consisting of a computer with an
Ethernet port and an E5810 or a set of networking devices that are
networked together but are not connected to an Enterprise network. The
figure on the next page shows example configurations for Local networks
with hub/switch or crossover ca ble co nnect ion s.
In a typical Local network (isolated LAN), a hub or switch may or may not act
as a Dynamic Host Configuration Protocol (DHCP) Server. For Local
Network connections, the E5810 is not visible on the Enterprise network. For
this configuration, multiple PCs can communicate with the E5810 via the hub
or switch.
For direct PC connection to the E5810, a crossover cable is connected from
the E5810 LAN port to a LAN card on the PC. There are no connections to
an Enterprise network. This setup is typically used for local configuration.
For this configuration, only a single PC can communicate with the E5810 via
the crossover cable.

The E5810 detects duplicate IP addresses and will not start operation if
its IP address is already in use. If you try to simultaneously attach multiple
E5810s without changing each unit’s default static IP address, some
E5810s may not start operation.
To prevent this from happening, add a single E5810 at a time to the
network and configure each E5810 to a unique IP address before adding
additional E5810s.
48 Chapter 2
Installing the E5810
Configuring the E5810 on a Local Network
Configuring the E5810 for Local Network Operation
This section gives guidelines to configure the E5810 on a Local network.
This section applies if you plan to configure the E5810 for eventual
installation on a non-DHCP Enterprise network or plan to configure the
E5810 for eventual use on the Local network.
NOTE
When configuring the E5810, we recommend you change the default IP
address to a unique IP address for each E5810 being added to the
system. Otherwise, since the E5810 detects duplicate IP addresses,
some E5810s added to the system may not operate. See Chapter 3 Using E5810 Web Access for details on setting E5810 parameters.
Establishing
Communication
With Your PC
Whether your Local network includes a hub/switch or a crossover cable, the
first step in configuring the E5810 is to establish communication between
your PC and the E5810. To do this, the PC and the E5810 must be on the
same subnet.
One way to put the PC and the E5810 on the same subnet is to use
route add <
MS-DOS prompt. For example, if IP address of your PC is 155.139.103.152
and the E5810 IP address is 169.254.58.10 (the default), use one of the
following:
! route is lost when the PC is rebooted
route add 169.254.58.10 155.139.103.152
! route persists when the PC is rebooted
route -p add 169.254.58.10 155.139.103.152
After communication has been established, you can set any required
configuration parameters for the E5810 by using the E5810 Web access.

including:
Using Interactive IO for Communication
Using Supported Programming Languages
NOTE
You can also communicate with (but not program) installed GPIB and/or
RS-232 instruments using the E5810 Web access, whether or not you

for Communication
Example: Usi ng
Interactive IO
After the E5810 has been configured and you have connected your GPIB
and/or RS-232 instruments to the E5810, you can verify communication
between your PC and the instruments by using the Interactive IO utility or by
using VISA or SICL commands with supported programming languages.
This section shows one way to use Interactive IO to verify instrument
communication.
NOTE
Once your remote interface(s) and instrument(s) have been configured in
Connection Expert, if you can see them in the Connection Expert explorer
and see their IDN string information in the detail pane then
communication has been verified. Interactive IO allows you to manually
verify communication and send specific commands to your instrument.
To use Interactive IO to send a *IDN? (identification) query to an instrument:
1 Select the instrument by clicking its icon in the Connection Expert
explorer view.

IO Libraries Suite Online Help for further information and guidelines on
programming with the Agilent IO Libraries.
Addressing
Instruments using
VISA and Remote
IO Client
Addressing
Instruments using
VISA and TCPIP
Interface
Once you have created a remote GPIB or remote serial interface in
Connection Expert, you can use ordinary GPIB or serial addressing in your
VISA or VISA COM programs to address instruments on these interfaces.
The Remote IO Client software maps TCPIP address requests into
appropriate interface type (GPIB or ASRL) addresses; thus the IP address
and hostname of the E5810 do not appear in the instrument address. This
makes it possible to use existing programs written for GPIB or ASRL without
having to modify code.
See “Configuring a Remote GPIB Interface” on page 66 or “Configuring a
Remote Serial Interface” on page 68 to configure a remote GPIB or remote
serial interface. VISA programs can then use addresses such as
GPIB0::22::INSTR (for GPIB) or ASRL1::INSTR (for RS-232). Use
these addresses in your viOpen() call as follows:
viOpen (...”GPIB0::22::INSTR”...)
viOpen (...”ASRL1::INSTR”...)
Although remote GPIB and remote serial interfaces are the most convenient
way to configure and program instruments on your E5810, you may choose
not to use them. For example, if you are using another vendor’s I/O software
rather than the Agilent IO Libraries Suite, your I/O software probably does
not support remote interface addressing. (At the time of this writing, only
Agilent software supports remote interface types.)
If you are not using remote interfaces, you will address your instruments as
TCPIP resources in VISA. These addresses include the IP address or
hostname of the E5810 as well as the SICL address of the device on the
E5810.
Use these addresses in your viOpen() call as follows. These examples
assume that the VISA interface ID of your TCPIP interface is “TCPIP0”. (You
can specify this interface ID with the Connection Expert utility ; “TC P I P0” is
the default VISA ID for the default TCPIP interface.)

SICL addresses include the IP address or hostname of your E5810 as well
as the SICL address of the device on the E5810, and optionally the protocol
to be used. Some example addresses for SICL programs follow. These
examples assume that the SICL interface ID of your TCPIP interface is “lan”.
(You can specify this interface ID with the Connection Expert utility; “lan” is
the default SICL ID for the default TCPIP0 interface.)

NOTE
At the time of this writing, National Instruments I/O software does not
support the SICL-LAN protocol, but only the VXI-11 protocol. Because
RS-232 instruments are only supported by SICL-LAN and not VXI-11, you
cannot use National Instruments I/O software to program an RS-232
instrument on your E5810.

Description
[Factory-Set]
An alphabetical listing of E5810 configuration parameter descriptions and
applicable default (factory-set) values follows. The E5810 uses the default
configuration values until you change any value and save/reboot. The
E5810 also uses the default values when you press and hold down the
Preset button for >10 seconds.
Description
This value is the IP address of the default subnet gateway that allows the
E5810 to communicate with systems that are not on the local subnet.
This is the default subnet gateway where packets are sent which are
destined for a device not on the local subnet, as determined by the
subnet mask setting. Only one default subnet gateway can be configured.
A value of
0.0.0.0 indicates that no subnetting is to be done.
The default description consists of “E5810 LAN/GPIB Gateway” followed
by the Ethernet (MAC) address. The Ethernet address is printed on a
label on the underside of the E5810.
A typical description is:
00-30-D3-05-00-23 is the Ethernet address. The description is the “UPnP

My Network Places, listed by this Description. A Friendly Name can be up
to 39 characters, including spaces.
A DNS Server is an Internet service that translates domain names into IP
addresses and vice-versa. Every time you use a domain name, a DNS
Server must translate the name into the corresponding IP address.
For example, the domain name
198.105.232.4. The DNS system has its own network. If one DNS Server
www.example.com might translate to
does not know how to translate a particular domain name, it asks another
DNS Server, etc. until the correct IP address is returned, if available.

Description
A DNS Server is an Internet service that translates domain names into IP
addresses. Every time you use a domain name, a DNS server must
translate the name into the corresponding IP address. For example, the
domain name
www.example.com might translate to 198.105.232.4.
The DNS system is distributed. If one DNS server does not know how to
translate a par ti c ular domain name, it asks anot he r DNS server, etc. until
the correct IP address is returned. If DHCP is used, a DHCP Server may
provide a DNS Server IP address to the E5810 (this is transparent to the
user). If the user configures a DNS Server, the E5810 will try to use that
Server first.
This parameter shows the IP address of the domain name Server. More
than one address may be listed on the
LAN/GPIB Gateway
page. Up to two of these values may have been
Current Configuration of the E5810
returned by the DHCP Server during startup. Only one static value can be
input on the
Configuring your E5810 LAN/GPIB Gateway page.
The DNS Server provides a Hostname, given an IP Address, for a LAN
device based on entries in its DNS lookup table. If DHCP is OFF and you
do not specify a DNS Server or if Dynamic DNS is not available on your
enterprise LAN and your IP Address is not in the DNS lookup table on the
DNS Server, your Hostname will be unknown and you must address the
E5810 only by its IP Address. The Hostname is not a required entry.
Dynamic Host
Configuration
Protocol (DHCP)
[ON]
DHCP is a protocol for assigning dynamic IP addresses to devices on a
network. DHCP supports a mix of static and dynamic IP addresses. The
two options for DHCP are ON (default) or OF F.
DHCP ON (Default): If DHCP is ON (the factory default setti ng), t h e E5810
will try to obtain an IP address from a DHCP Server. If this fails, the
E5810 will use its static IP address. If DHCP is ON and a DHCP Server is
found, the manually configured IP Address, Subnet Mask, and Default
Gateway parameters are not used by the E5810 during startup and thus
are not required settings.

The individual Serial Number assigned at the factory for each E5810. The
Serial Number is printed on a label on the underside of the E5810 and
has the form US12345678.
This is the Media Access Control Address, also known as the link-level
address, the Ethernet (station) Address, the LANIC ID and Hardware
Address. This is a unique 48-bit address assigned by the manufacturer
for each Ethernet device. The address is usually 12 hexadecimal
characters, with colon or dash separators between every two characters,
such as “00:30:D3:05:00:23” or “00-30-D3-05-00-23”. The Ethernet
address is printed on a label on the underside of the E5810.
This value configures the GPIB bus address of the E5810. This address
is used when transfers are made on the GPIB bus. A SICL client
application can change this value by using the SICL function
IGPIBBUSADDR. The GPIB address value can be any number 0 through
30.
GPIB Logical Unit

[gpib0]
This value is the interface logical unit (LU) number of the GPIB interface
in the E5810. It may be used in an Agilent SICL client application’s iopen
statement to uniquely identify the GPIB interface in the E5810. The GPIB
logical unit value can be any number
1 through 255.
This value is the symbolic name of the GPIB interface in the E5810. It is
used in a SICL client application’s
iopen operation to symbolically
reference the GPIB interface in the E5810. The maximum length of the
GPIB interface name is 15 characters. If VXI-11 (TCP/ IP Instrument

I/O Timeout
[120 sec]
Description
This value configures the internet domain name for the E5810.
Hostnames are useful when IP addresses are being assigned by a DHCP
Server, since the Hostname will not change despite DHCP Server
changes and device IP address changes.
If a Hostname is entered, the E5810 will try to regist er this nam e when it
boots. The E5810 can only register the Hostname if the network has
Dynamic DNS. If the network does not have Dynamic DNS, this value is
not used. Since you can always use the IP Address or the name (possibly
supplied by another name Server), the Hostname is not a required
configuration value.
You m ay enter up to 35 characters for the Hostname. The Hostname
must start with a letter and consists of upper and lower case letters and
digits and dashes. There is no default Hostname. If a Hostname is
displayed on the
Welcome page, it is a valid Hostname, since one was
found on the network through DNS.
This value sets the Server I/O timeout in seconds. It configures the E5810
to use an I/O timeout of the specified amount of seconds if the client
requests a timeout of infinity. If
0 is specified for this value and the client
requests an infinite timeout, the E5810 will use a timeout of infinity as
requested.
Settin g th e I/O timeout to 0 is NOT recommended, as this can result in the
E5810 waiting indefinitely for an I/O operation and effectively “hang” the
E5810.
This timeout value may be used to ensure that the E5810 does not wait
indefinitely for an I/O operation. It also allows the E5810 to detect certain
network events (such as when a client connection is dropped) that may
otherwise go undetected. If the E5810 detects such a condition, it will
release any resources, such as locks, associated with the client.
This value also allows the E5810 to detect certain network events, such
as when a client connection is dropped. If the E5810 detects such a

IP Address
[169.254.58.10]
LAN Keepalive
[7200 sec]
Description
This value is the Internet Protocol (IP) address of the E5810. The IP
address is a required value and is used for all IP and TCP/IP
communications with the E5810. The IP address is represented in dotted
decimal notation (for example,
154.140.222.201). This number is assigned
by the System Administrator. The E5810 has a default static IP address
of
169.254.58.10.
LAN traffic to the E5810 will be routed by the IP Address or by using a
Hostname that may be provided by a DNS name Server which is mapped
to this IP Address. The current E5810 IP Address may have been
established in one of two ways:

set for your network.
This value sets the LAN connect timeout in seconds. The E5810 may use
the TCP keepalive timer of the TCP/IP protocol stack to determine if a
client is still reachable. By specifying this configuration value, the E5810
turns on the keepalive timer when connecting to the client.
After the specified time, if there has been no activity on the connection,
the E5810 sends keepalive probes to the client to determine if it is still
alive. After a specified amount of time, the connection w ill be m arke d as
down (“dropped”), and the E5810 will release any resources which were
allocated to the associated client.
A value of
0 means no ti meout is se t. Th u s , th e E5810 will wa it for ev e r
and no keepalive probes are sent. If this value is set, it is recommended
that the largest value be used which still meets the application’s need for
unreachable client detection.
Smaller LAN Keepalive values will generate more keepalive probes
(network traffic), using more of the available network bandwidth.
Allowable values are 0 and greater than or equal to 600 seconds (10
min). The factory default setting is 7200 sec (2 hrs).

Check Hardware. A broken GPIB instrument may short out the GPIB
cable and cause all instruments to show a failure. If you are
experiencing problems, try connecting only one GPIB instrumen t to the
E5810 at a time. Possible causes of the problem may be broken cable,
loose connectors, two or more instruments at the same GPIB address,
an instrument may be broken, or the E5810 may be broken.

Reboot the E5810. After checking hardware connections, reboot the
E5810 to do a self-test of E5810 hardware.
