Safety Precautions
The following safety precautions should be observed before using this product and any associated instrumentation. Although
some instruments and accessories would normally be used with non-hazardous voltages, there are situations where hazardous
conditions may be present.
This product is intended for use by qualified personnel who recognize shock hazards and are familiar with the safety precautions
required to avoid possible injury. Read and follow all installation, operation, and maintenance information carefully before using the product. Refer to the manual for complete product specifications.
If the product is used in a manner not specified, the protection provided by the product may be impaired.
The types of product users are:
Responsible body is the individual or group responsible for the use and maintenance of equipment, for ensuring that the equipment is operated within its specifications and operating limits, and for ensuring that operators are adequately trained.
Operators use the product for its intended function. They must be trained in electrical safety procedures and proper use of the
instrument. They must be protected from electric shock and contact with hazardous live circuits.
Maintenance personnel perform routine procedures on the product to keep it operating properly, for example, setting the line
voltage or replacing consumable materials. Maintenance procedures are described in the manual. The procedures explicitly state
if the operator may perform them. Otherwise, they should be performed only by service personnel.
Service personnel are trained to work on live circuits, and perform safe installations and repairs of products. Only properly
trained service personnel may perform installation and service procedures.
Keithley products are designed for use with electrical signals that are rated Installation Category I and Installation Category II,
as described in the International Electrotechnical Commission (IEC) Standard IEC 60664. Most measurement, control, and data
I/O signals are Installation Category I and must not be directly connected to mains voltage or to voltage sources with high transient over-voltages. Installation Category II connections require protection for high transient over-voltages often associated with
local AC mains connections. Assume all measurement, control, and data I/O connections are for connection to Category I sources unless otherwise marked or described in the Manual.
Exercise extreme caution when a shock hazard is present. Lethal voltage may be present on cable connector jacks or test fixtures.
The American National Standards Institute (ANSI) states that a shock hazard exists when voltage levels greater than 30V RMS,
42.4V peak, or 60VDC are present. A good safety practice is to expect that hazardous voltage is present in any unknown
circuit before measuring.
Operators of this product must be protected from electric shock at all times. The responsible body must ensure that operators
are prevented access and/or insulated from every connection point. In some cases, connections must be exposed to potential
human contact. Product operators in these circumstances must be trained to protect themselves from the risk of electric shock.
If the circuit is capable of operating at or above 1000 volts, no conductive part of the circuit may be exposed.
Do not connect switching cards directly to unlimited power circuits. They are intended to be used with impedance limited sources. NEVER connect switching cards directly to AC mains. When connecting sources to switching cards, install protective devices to limit fault current and voltage to the card.
Before operating an instrument, make sure the line cord is connected to a properly grounded power receptacle. Inspect the connecting cables, test leads, and jumpers for possible wear, cracks, or breaks before each use.
When installing equipment where access to the main power cord is restricted, such as rack mounting, a separate main input power disconnect device must be provided, in close proximity to the equipment and within easy reach of the operator.
For maximum safety, do not touch the product, test cables, or any other instruments while power is applied to the circuit under
test. ALWAYS remove power from the entire test system and discharge any capacitors before: connecting or disconnecting ca5/02
bles or jumpers, installing or removing switching cards, or making internal changes, such as installing or removing jumpers.
Do not touch any object that could provide a current path to the common side of the circuit under test or power line (earth) ground. Always make measurements with dry hands while standing on a dry, insulated surface capable of withstanding the voltage being measured.
The instrument and accessories must be used in accordance with its specifications and operating instructions or the safety of the
equipment may be impaired.
Do not exceed the maximum signal levels of the instruments and accessories, as defined in the specifications and operating information, and as shown on the instrument or test fixture panels, or switching card.
When fuses are used in a product, replace with same type and rating for continued protection against fire hazard.
Chassis connections must only be used as shield connections for measuring circuits, NOT as safety earth ground connections.
If you are using a test fixture, keep the lid closed while power is applied to the device under test. Safe operation requires the use
of a lid interlock.
If
The
or
!
is present, connect it to safety earth ground using the wire recommended in the user documentation.
symbol on an instrument indicates that the user should refer to the operating instructions located in the manual.
The
symbol on an instrument shows that it can source or measure 1000 volts or more, including the combined effect of
normal and common mode voltages. Use standard safety precautions to avoid personal contact with these voltages.
The WARNING heading in a manual explains dangers that might result in personal injury or death. Always read the associated
information very carefully before performing the indicated procedure.
The CAUTION heading in a manual explains hazards that could damage the instrument. Such damage may invalidate the warranty.
Instrumentation and accessories shall not be connected to humans.
Before performing any maintenance, disconnect the line cord and all test cables.
To maintain protection from electric shock and fire, replacement components in mains circuits, including the power transformer,
test leads, and input jacks, must be purchased from Keithley Instruments. Standard fuses, with applicable national safety approvals, may be used if the rating and type are the same. Other components that are not safety related may be purchased from
other suppliers as long as they are equivalent to the original component. (Note that selected parts should be purchased only
through Keithley Instruments to maintain accuracy and functionality of the product.) If you are unsure about the applicability
of a replacement component, call a Keithley Instruments office for information.
To clean an instrument, use a damp cloth or mild, water based cleaner. Clean the exterior of the instrument only. Do not apply
cleaner directly to the instrument or allow liquids to enter or spill on the instrument. Products that consist of a circuit board with
no case or chassis (e.g., data acquisition board for installation into a computer) should never require cleaning if handled according to instructions. If the board becomes contaminated and operation is affected, the board should be returned to the factory for
proper cleaning/servicing.

Introduction
Model 2701 Instrument Networking Instruction Manual
General information
Keithley's Model 2701 is the industry's first multipoint measurement and control system that
fully integrates instrument quality resolution and sensitivity with Ethernet long distance networking capability. This allows for sensitive measurements in a distributed data acquisition
environment using long distance industry standard communications.
Using the Model 2701 can reduce networking costs by requiring only one computer, as compared to traditional systems where separate computer/controllers may be needed with each
instrument or DAQ system. In addition, using Ethernet to control the Model 2701 provides reliable measurements without the configuration and installation challenges of traditional GPIB
alternatives. With a Model 2701, there is no need to open a PC or install separate communication interfaces such as GPIB boards. Just connect the Model 2701 directly to the PC’s Ethernet
port via a cross over RJ-45 cable, which is included with the Model 2701.
The Model 2701 can be controlled and provide readings over an Ethernet connection using
TCP/IP protocol. The Model 2701 contains an integral web server which provides diagnostic
control of the Model 2701 through ActiveX controls. The web pages accessed via the built-in
web server allow the user to view diagnostic information, view and edit the Instrument's networking configuration, take and display simple readings, and send the instrument SCPI commands and display the results. The 2701’s IP address, as well as Subnet mask, Gateway, DHCP,
among other items, can be set from the instruments front panel or over the Ethernet connection
(see Section 3). To access this page, type the 2701’s IP address into IE's address field (just like
any other web address, but without the www, for an example, see Figure 3-2).
Full access to the instrument can be obtained via a TCP/IP socket connection. Using this
socket connection, the 2701 may be fully configured and controlled, as well as all measurement
data read. A custom software program that uses a socket connection can be written to access the
instrument. The ActiveX controls on the web page establish a socket connection to the instrument and use it to obtain the diagnostic information, send commands, and retrieve responses.
The Instrument Driver Software also uses this socket connection.
Call Keithley or visit www.keithley.com to order a free Model 2701 application note that
discusses programming multiple 2701s using the IVI/VISA driver, as well as the direct Windows socket interface. The requirement for network topology is a functioning Ethernet. This
can be a direct connection between a PC and a single 2701 through a cross over cable or over a
corporate LAN. This manual provides user information for isolated network connections. For
corporate LAN installations, contact your IS/IT department before making any connections to
your building’s network.

Contact information
Worldwide phone numbers are listed at the front of this manual. If you have any questions,
please contact your local Keithley representative or call a Keithley Application Engineer at
1-800-348-3735 (U.S. and Canada only).
Features of the Ethernet interface
This section describes the Model 2701 Ethernet interface control. The Model 2701’s adapter
supports 10BaseT and 100BaseTX Fast Ethernet. Through design, the Model 2701 integrates
easily with fast Ethernet hubs and switches.
NOTE
To operate at 10 Mbits/sec, a category 3 (or higher) UTP cable is required. To operate at 100 Mbits/sec, a category 5 UTP cable is required.
Autosensing
The Model 2701 autosenses the Ethernet connection speed (either 10BaseT or 100BaseTX).
This allows the Model 2701 to auto-switch to the proper speed providing compatibility with
both network speeds.

Model 2701 Instrument Networking Instruction Manual
Overview
Keithley’s Model 2701 is a multipoint measurement and control system that fully integrates
instrument quality resolution and sensitivity in an Ethernet-based data acquisition (DAQ)
system. The Model 2701 is designed for a 10/100BaseTX network using standard RJ-45
connectors. This is an eight wire connector, but only two sets of wire pairs are used: one pair to
transmit and one pair to receive data. A 10BaseT network can accommodate transmission
speeds up to 10Mbit per second where a 100BaseTX network operates at speeds of up to
100Mbit per second. Both types of networks usually require Ethernet hubs to make
connections. The exception is a one to one connection using a cross over cable, which may be a
10BaseT or 100BaseTX dependent on the PC’s Ethernet interface card and which category of
cable is used.
Information on four connection schemes is detailed in this section:
•
•
•
•
Direct connection—PC to Model 2701 through a cross over cable (provided).
Hub connection—PC to one or more Model 2701s.
Dual interface card connection—PC with two interface cards. (One for the Model 2701
network and one for the corporate network—each network isolated.)
Corporate network connection—requires IS/IT or Network Administrator.

Network Connection
Model 2701 Instrument Networking Instruction Manual
Dual interface card connection
NOTE
This scheme requires a second network interface card installed in the PC. The first
interface card (connected to other network resources) will remain connected. (Email
and other network resources available before connection to the Model 2701 will still
be available using this scheme.)
NOTE
Different available IP addresses are required for each Model 2701 and each network
interface card connected to the Model 2701 network.
This section contains information on connecting the PC to the Model 2701 while still
maintaining connection to a corporate network. Use this type of scheme when it is desirable to
have the same PC used for connection to the Model 2701 while retaining the capabilities of
connection with the corporate network (such as for email or intranet applications). This scheme
maximizes the performance of the network connections to the instruments by isolating
corporate network traffic from the 2701 and the PC (i.e., when the instruments are connected to
a corporate LAN, the network traffic on the LAN can slow down communications with the
2701).
When using this connection scheme, the TCP/IP settings for the PC’s Ethernet card and the
Model 2701 will need to be set manually (see Section 3).
Procedure
This connection can be made directly to the Model 2701 or to a hub (see Figure 2-3).
Table 2-4 contains parts required for a connection through a hub and Table 2-5 contains parts
required for a direct connection. Complete connections for the desired scheme. Refer to “Direct
connection” on page 2-3 or “Hub connection” on page 2-4 for details. The TCP/IP settings for
the Ethernet port the on the PC and the Model 2701s will need to be set manually (refer to
Section 3). Make sure to use settings that do not interfere with the existing network (consult IT/
IS department if unsure).

This section contains information on connecting the Model 2701 to one or more devices
using an Ethernet hub or switch (Figure 2-4) that is part of larger local area network (LAN).
The LAN administrator must be consulted for the correct settings. Connections require
Ethernet straight-thru cables.

CAUTION
NOTE
When connecting the Model 2701 (or any other host) to a corporate network, the sites network administrator MUST provide all of the network
settings for the Model 2701 including IP address, subnet, and gateway.
Failure to use settings provided by the sites Network Administrator could
result in failures at other locations on the corporate network. Failure to
work through the Network Administrator could also be considered a
breech of company policy. Always consult with the Network Administrator
before attempting to connect instrumentation to the network.
Network administrators refer to the IS/IT department section of Communication
protocol for specific information about the capabilities of the Model 2701.

Configuring TCP/IP addresses
Model 2701 Instrument Networking Instruction Manual
Communication protocol
The TCP/IP Protocol is the protocol the Model 2701 uses to communicate over the Ethernet
connection to the PC. The Model 2701 TCP/IP settings may be configured either manually (on
the device) or through the use of a DHCP (Dynamic Host Configuration Protocol) server when
connected to a local area network (LAN). The IP settings consist of an IP address, Subnet
mask, and gateway address.
A Network Administrator is required to provide the IP settings (addresses) if the connection
is made to a LAN. If the network will be isolated from the LAN, the connection can be made
without a Network Administrator—refer to “Direct connection (isolated network)” on page 3-4
for information on manual configuration of IP addresses.
CAUTION
When connecting the Model 2701 (or any other host) to a corporate
network, the network administrator MUST provide all of the network
settings for the Model 2701 (IP address, subnet, and gateway). Failure to
use settings provided by the Network Administrator could result in failures
at other locations on the corporate network. Failure to work through the
Network Administrator could also be considered a breech of company
policy. Always consult the Network Administrator before attempting to
connect instrumentation to the network.
IS/IT department
The Model 2701 supports DCHP. (If a DHCP server is present on the network, it will
automatically provide the correct settings to the Model 2701 if the 2701 is powered up while
connected to the network.) When adding the device to a network, if a DHCP server is available,
the DHCP server will download the IP address, Subnet mask, and gateway address to the
Model 2701 upon powering it up on the network. Contact the IS/IT department for access to
the DHCP server. The network parameters acquired from the DHCP can be viewed from the
Model 2701 front panel menu or queried over the bux. If no DHCP server is available, the
Network (LAN) administrator must assign these values to ensure proper operation of the device
and to avoid conflicts with other devices on the network.
NOTE
The Model 2701 supports DCHP. This 2701 setting can be changed over the
Ethernet connection using the built-in web page or from the front panel (refer to
“Changing Model 2701 TCP/IP addresses” on page 3-7).
Usually the instruments are kept inside the corporate firewall, but the Network
Administrator could assign resources that allow them to be outside the firewall. Placing the
resources outside the firewall would allow a Model 2701 connection to the internet using
appropriate security methods. This would allow data collection and distribution control from
virtually any location in the world.

Configuring TCP/IP addresses
Model 2701 Instrument Networking Instruction Manual
Direct connection (isolated network)
When connecting the device directly to the Ethernet port of a PC or to a hub that is not part
of a larger network, the IP address and Subnet mask must be configured manually (the gateway
address is not relevant in this case).
The IP address is a 32-bit identifier consisting of four one byte (8-bits) sections, commonly
notated in dotted decimal format (i.e. 145.90.120.240). The Subnet mask is a second 32-bit
identifier that designates what portion of the IP address identifies the subnet and what portion
identifies the device (i.e. 255.255.255.0). In this example, 145.90.120 is the network address
and 240 is the device address. Gateway addresses are typically the device address 1 (e.g.,
145.90.120.1).
Networks are commonly grouped into three classes based on the first byte of the address:
Table 3-2
Network classes

IP Address Example
100.1.1.1
128.1.1.1
191.1.1.1
Address restrictions
NOTE
Different available IP addresses are required for each node (this includes each 2701
and each network interface card connected to the instruments network).
The following IP addresses are reserved—do not assign them to any device (either interface
card or Model 2701):
Do not assign…
any address beginning (first byte) with 0 or 127 (reserved for loopback test),
any address beginning (first byte) with 224 through 255,
any address ending (last byte) with 0 or 255.
Other than the restricted addresses, any dis-similar address may be assigned to the PC’s
Ethernet interface card and to each Model 2701. Keep in mind that when creating and assigning
an address, the one assigned to the Model 2701 has to be of the same class as the network. For
example, if you want the Model 2701’s IP address to be 192.168.0.2 (the default), the Subnet
mask should be 255.255.255.0. Also, to communicate with the Model 2701, the PC's Ethernet
Interface card must be set to the same class (same Subnet mask and Network ID).
NOTE
Without the correct Subnet mask or Network ID, the direct network will not function.

Problem
Web page opens, not able to connect to 2701 (settings and data
fields on the web page are blank or
filled with dashes or asterisks).
Not able to open the Model 2701
web page.
Possible causes
Subnet mask incorrect (check both the Model 2701 and
the PC to make sure they are the same).
Security not correctly set in IE. Add the IP address of
the Model 2701 to trusted sites. Make sure the ActiveX
controls are allowed.
There already is a connection to the 2701 (no more
than one connection is allowed at a time).
Past connection not closed. Cycle power the 2701 to
close previous connection (turn off and then back on).
Incorrect cable type (cross over cables should not be
used to connect to hub, straight through cables should
not be used to connect directly to the Model 2701 without a hub).
IP address conflict. Make sure each node (interface
card and 2701) has a unique IP address, but share the
same Subnet mask and network ID.
Network device problems. Check the interface cards
setup (refer to the specific cards instructions or the PC
manual for additional information).
Use of an unsupported web browser or operating
system.
Mistyped IP address. Check for proper IP address and
refresh as necessary.
Instrument is set to use Serial Interface. On the 2701
front panel, press: Shift >> RS-232 and set to OFF.
Instrument is set to use DHCP but cannot obtain IP
address from DHCP server. If you try to view the IP
address and only dashes are shown, then instrument
could not obtain IP address. Make sure DHCP server is
available on network and is configured properly.
NOTE
When using DHCP, it is normal for the
instrument to show dashes instead of the IP
address when it is first powering up,
because it does not obtain the IP address
from the server until later in the start up
sequence.

properly, try selecting the standard VGA driver in
Windows Setup (under the control panel). If this solves
the problem, try obtaining the latest version of the
drivers.
IP addresses that are assigned by the IS/IT department
may take a period of time before they are active. Check
with them as to when the IP address will become
active.
Network IDs may be different in different parts of the
corporate network (network design dependent). Make
sure you specifically tell the IS/IT where you are going
to connect the 2701 to the network as location may
determine the 2701’s correct subnet.
If you have an instrument connected to a router or a
switch, the MAC address is usually cached with the IP
address for a period of time. The router or switch will
not recognize the instrument if the IP address is
changed or if the cached IP address is assigned to a
different instrument. Contact your IS/IT department for
additional details about how the router/switch is configured.

The free TestPoint runtime start-up software package (Figure 4-2) provides basic data
logging capabilities, so a system can be up and running almost immediately. A few clicks of the
mouse are all it takes to confirm that the system's hardware, wiring, communications, and
software drivers are installed and operating correctly. Data from multiple channels of a single
2701’s can be saved to disk; up to eight channels of data can be graphed automatically and
multiple configurations can be saved to disk.
Refer to Table 4-1 for a description of the TestPoint runtime start-up software packages
features. If the application demands greater functionality, this free runtime software can be
modified with the TestPoint application development package (described later).

Additional software applications
Keithley has the software needed to get the most performance from a Model 2700 or 2750
Multimeter/Switch System. Our broad range of software solutions makes it easy to get R&D,
quality assurance, and production applications “Up & Running” quickly and economically. The
following programs for the Model 2700/2701/2750 are available separately.
ExceLINX-1A
ExceLINX-1A (Figure 4-3) is an economical, easy-to-use, add-in utility for Microsoft Excel
and Keithley Integra Series Multimeter/Switch systems. No programming is required—configure your measurements quickly using pop-up menus and eliminate time-consuming and error
prone programming. Acquire data into a spreadsheet on the fly during a scan or transfer data
into a spreadsheet after a scan is completed. A few mouse clicks are all it takes to configure
channels, set parameters, triggers, and scan lists. There is no need to launch a separate data logging or data-crunching application; live data streams automatically into an Excel workbook,
ready for analysis or charting using all of Excel's powerful built-in tools.
Within minutes of installing ExceLINX-1A on a PC, users can acquire data directly from the

Software and Drivers
Model 2701 Instrument Networking Instruction Manual
Provided software and driver installation
NOTE
Make sure the instrument is properly connected and configured to a controlling PC
before installation of the software or drivers. Installation of the software or the
drivers will not correct an improperly configured Ethernet.
Installation and configuration
Before installing the software provided with your Model 2701 instrument, make sure the
instrument is properly connected and configured to a controlling PC as described in previous
sections of this manual. Installation of the software and driver will not correct an improperly
configured Ethernet. It is recommended that you use the built-in web page to verify your
system set-up and configuration before installing the start-up software and/or instrument driver
(if the web page displays and is able to control the Model 2701, the Ethernet is functioning
correctly).
Installing the start-up software and driver
To install the start-up software and the instrument driver, insert the software CD provided
with your instrument. The installation utility should run automatically. If it does not start automatically, navigate and run the install.exe program in the root directory of the CD. Follow the
on-screen prompts to install both the start-up software (TestPoint runtime) and the KE2700
instrument driver.
Although the software provided on the CD is the current version at time of shipment, it is
recommended that you visit the Keithley Web site (www.keithley.com) to check for available
updates.
Configuring instrument communications
Before you run the start-up software or use the instrument driver, you must configure the
communications with your instrument. Make sure your instrument is properly connected to
your computer and then run the Keithley Configuration Utility to configure communications.
When the configuration utility opens, the configuration wizard will also open. The wizard
allows you to add, modify, and delete instruments from your configuration. It is recommended
that you use the wizard for all routine configuration tasks. The configuration panel provides
extra capability for advance configuration tasks.
Use the following steps to configure communications. The example screen captures shown
illustrate the steps required to configure the software to communicate to a Model 2701 using
Ethernet. Before using this utility, you must have already configured your PC’s network communications and chosen your instrument's network address as described earlier in this manual.
NOTE
Close all applications that use the KE2700 Instrument Driver before using the configuration utility to make changes.

Advanced configuration
The configuration panel may be used to adjust advanced configuration settings by those
familiar with VISA and IVI Instrument configuration. We recommend you not adjust advanced
settings unless you are completely familiar with their purpose and effects.
One advanced setting that many advanced users may wish to adjust is the QueryInstrStatus
attribute setting. By default, the KE2700 Instrument Driver checks the instrument for errors
after every command. While this provides the safest operation and provides the most useful
information in the event of a program or instrument fault, disabling this feature considerably
speeds up instrument communications. Advanced users may wish to modify the setting of this
attribute as described below. We recommend that you leave this function enabled until you are
satisfied your application is operating correctly. Then, turn off the error checking to improve
performance.
To change the attributes of QueryInstrStatus, use the following procedure.

information and runs a server program that other systems across the Internet can query. The
DNS provides the protocol that allows clients and servers to communicate with each other.
Dynamic Host Configuration Protocol (DHCP) — A feature of Windows NT server that
automatically assigns IP addresses to hosts on a TCP/IP network whenever the hosts starts up.
Bridge — A device that passes network data between two segments of network.
Ethernet — A network technology invented by Xerox Corporation and developed jointly by
Xerox, DNEC, and Intel.
Firewall — A hardware or software component in the data path between the internet and an
internal network. The firewall filters packets by examining them on one side and deciding what
to pass along to the other side.
Gateway — A computer that acts as a translator on the network or as a router between two
network technologies. It can also act as a translator between two different network protocols.
Host — Defined as anything on the network that can transmit and receive IP packets on a
network. This would include workstations, servers, and the Model 2701.

Hub — A passive hub is a device that splits the received signals among other connected
nodes. An active hub amplifies or repeats incoming signals before distributing them.
INterNIC (Internet Network Information Center) — The organization responsible for
assigning Internet network addresses and domain names to hosts that are connected to the
Internet.
IP Address — A unique 32-bit address assigned to each host attached to the network. An IP
address specifies both the network and the host address.
MAC Address — Media access control is the hosts unique identity. It is a 6 Byte
hexadecimal number that can be represented in HEX or decimal. The Model 2701 uses a
decimal number, much like an IP address structure to represent the MAC address. The MAC
address is usually assigned to the HOST at the factory. The host transmits its address with each
packet of data. It may also be referred to as a hardware address, Ethernet address, node ID, or
adapter address. This is not required to be known when using an isolated network. A systems
administrator may require this when connecting to a corporate network.
