Welcome to VocalLink. VocalLink is an easy-to-learn and easy-touse speech recognition interface between your PC and a supported
oscilloscope. Without touching an oscilloscope or even being in the
room, you can obtain measurements and control the functions of the
oscilloscope using an extensive set of verbal commands.
The Pro version has a macro capability that lets you combine a group
of voice commands, plus enter GPIB command strings, then execute
the macro with a few words. These macros simplify using the
oscilloscope without sacrificing its sophistic ated capabilities.
Product Description
VocalLink is a software application that insta lls on a PC running
Windows 95, 98, 2000, and NT 4.0 operating systems that connects
to the following Tektronix oscilloscopes. The VocalLink package
contains software, headset, microphone, and a user manual.
There are two versions of VocalLink software:
H Basic -- This version accepts the basic set of verbal commands to
obtain measurements from the Tektronix oscilloscope.
H Pro -- This version has the same features as the Basic version,
plus an extended set of Macro commands that allow you to create
a macro to obtain measurements, use GPIB command strings, and
control the function of the oscilloscope. T he macro GPIB
commands are not available for use on the T DS7000 series.
The instruments supported by VocalLink are listed in the CD Rom
booklet that came with your software.

The following voice command set for Basic and Pro VocalLink
software is also listed in the Help > Commands menu.
You must use an attention word before each command phrase.
You would say the command phrase [Daisy] scale/voltage up [up] as
“Daisy scale up” to increase the scale or “Daisy scale up up” to
increase the scale more.
The attention word [Daisy] can be replaced with other attention
words (see page 3--9). A bracket [ ] indicates an optional word and
a parentheses ( ) indicates you must choose between two or more
words. Not all commands are possible on all oscilloscopes. If a

Appendix A: RS-232
This section provides instructions to set the default RS-232 values on
various Tektronix oscilloscopes and some general troubleshooting
help.
Setting RS-232 Default Values
Refer to the following information for RS-232 interface connections
for your specific oscilloscope family.
TDS 3000 Series Oscilloscopes
If you are using a TDS 3000 Serie s oscilloscope, you can use the Set
RS-232 Parameters to Default Values button to set the RS-232
settings on the oscilloscope to the default values.
Follow the steps below to access the Set RS232 Parameters to
Defaults button.
1. Push the Utility button on the oscilloscope.
2. Push the bottom left bezel button (System Config) on the
oscilloscope repeatedly until I/O is selected.
3. Select RS-232.
4. Push the fifth bezel button on the oscilloscope (labeled Set RS232
Parameters to Default).
You can examine the Error Log for clues about your RS-232
interface connection. Follow the steps below to access the Error Log:
1. Push the Utility button on the oscilloscope.
2. Push the bottom left bezel button on the oscilloscope repeatedly
until Diag is selected.
VocalLink Software User Manual

Appendix A: RS-232
3. Push the bezel button on the oscilloscope labeled Error Log.
Check the lines in the Error Log titled RS-232 Line Snapshot and
RS-232 Errors. Refer to the programmer manual for your oscilloscope for information about interpreting the information in the Error
Log.
TDS500, TDS600, and TDS700 Series
The TDS500, TDS600, and TDS700 Series oscilloscopes may
support RS-232 printers but c annot be controlled over the RS-232
interface. VocalLink Software can only communicate with these
series of oscilloscopes using a GPIB interface connection.
RS-232 General Hints
H Make sure the communication parameters are set correctly on the
oscilloscope. Baud rates should be the same, Parity should be
None, Data Bits should be 8, and Stop Bits should be 1.
Soft flagging should never be used for waveform and hardcopy
transfers. This is because waveform data and hardcopy output
contain binary characters which can easily include the XON and
XOFF characters used to implement soft flagging. Soft flagging
should only be used for transferring stored setups since stored
setup information generally consists of printable ASCII text.
H Although it generally should not matter if the EOL characters are
the same, set the EOL to CRLF to be sure there are no problems.
A- 2
VocalLink Software User Manual
Appendix A: RS-232
H Not all instruments support full RS-232 communications. Some
instruments only support GPIB c ommunication, while others
support limited RS-232 functions, such as printer functions.
H If you are able to connect to an instrument but unable to transfer
waveforms successfully, you may have a cable that is not wired
correctly for hard flagging.
If you can successfully transfer settings to and from the
instrument at the fastest supported baud rate, hard flagging is
probably working. If not, try soft flagging. If you can successfully
transfer settings using soft flagging but not with ha rd fla gging,
there is a good chance the hard flagging li nes of your cable are
not connected properly.
RS-232 Cable Issues
If the information provided so far in this section fails to resolve your
RS-232 problems, try the following information:
H You might be using an incompatible RS-232 cable. There is no
such thing as a standard RS-232 cable , so you may need to use an
ohmmeter to verify that your cable is wired correctly. Many
cables do not have all of the pins connected.
H Determine whether the PC and oscilloscope are DTE (Data
Terminal Equipment) or DCE (Data Communications Equipment)
devices. This information is in the documentation provided with
your oscilloscope and with your PC.
VocalLink Software User Manual
A- 3
Appendix A: RS-232
H If you are connecting a DTE device to a DCE device you will
need a straight-through cable. This is a cable that has the same
pin assignments on both ends of the cable.
H If you are connecting two devices of the same type, you need a
null modem cable. This is a cable whose lines are crossed such
that the inputs of one device are connected to the outputs of the
other.
CAUTION. Do not connect the output lines of two same-type devices
to each other. Doing so will damage one or both of the devices.
H For hard flagging to work, the RTS (Request To Send) and CTS
(Clear To Send) lines must be connected. Use an ohmmeter to
verify that they are actually connected since not all cables
connect these lines. The RTS line is sometimes referred to as
RFR.
H The DCD (Data Carrier Detect) line is not used by VocalLink so
it does not matter whether or not it is c onnected. The DCD line i s
sometimes referred to as RLSD.

Appendix C: TekVISA
Appendix C provides information about VISA files, and how to
configure the TekVISA utility when using AD007 GPIB-LAN or
TDS3EM communication modules.
Choosing a VISA File
TekVISA is the Tektronix version of VISA software. Typical ly, only
one version of VISA (Visa32.dll file ) is located in your C:/windows/
system at a time. If you have another company’s VISA on your
system, then you must choose between TekVISA and that other
VISA. VocalLink software will only use a VISA file called
Visa32.dll.
To choose between TekVISA and another VISA, you will need to
consider further information. Choosing a VISA File, will help you
with this decision.
If you decide to have two VISA files, Managing Two VISA Files (see
page C--2) will guide you through the renaming process for these
VISA files.
If you choose to overwrite the existing Visa32.dll file, the installation
process will delete any other Visa32.dll file in your System directory
of Windows and replace it with the TekVISA Visa32.dll file.
NOTE. Review the following information when choosing between
TekVISA and another company’s VISA.
H The AD007 GPIB-LAN Adapter and the Tektronix TDS3EM
requires TekVISA.
H The VocalLink software may work with a VISA from another
company, provided their VISA software supports the int erface
types with which you are working. If you choose to use a VISA
from another company and find it does not work with the
VocalLink Software User Manual
C- 1
Appendix C: TekVISA
VocalLink software, you can install TekVISA later using the
VocalLink installer.
H TekVISA does not support VXI Mainframe communication.
Managing Two VISA Files
To keep two different VISA files, you will need to rename the
existing VISA file and then copy the other VISA file you want to use
to your system.
In the following example, you have t wo VISA files (one is from
National Instruments, one is TekVISA), and the current VISA file is
the National Instruments (NI).
To overwrite the NI VISA file, follow these steps:
1. Rename the NI VISA file to Visa32_ni.dll
2. Copy the TekVISA Visa32.dll file into the Window’s System
directory.
VocalLink can now use the TekVISA Visa32.dll file.
Configuring TekVISA for AD007 GPIB-LAN or TDS3EM
Check that your instrument is connected to the LAN and is assigned
a valid IP address. If you do not know the IP address check with your
network administrator.
Follow the steps below to add the IP address of the instrument to the
TekVISA configuration program.
1. Select Start > Programs > TekVISA > VISA Configuration to run
the TekVISA configuration program. The program will take a few
moments to locate current resources.
2. Select the Add button in the Remote Hosts pane to open the Add
Remote Host dialog box.
3. Enter the IP address of your instrument in the Host Name field.
For example, 128.23.304.45. Do not enter or change the values in
the other fields.

4. Select the OK button. The configuration program closes the Add
Remote Host dialog box and searches the LAN for the specified
address.
5. The configuration program updates the TekVISA Configuration
dialog box with the VISA resource for the newly-added
instrument.
NOTE. The VISA Configuration program labels Ethernet and GPIB
resources as GPIBx::x::xxx; this is OK. The RS--232 resources are
labeled as ASRL::INSTR
6. If the VISA Configuration program does not locate your
instrument, verify with the network administrator that:
H The instrument has a valid IP address
H The instrument IP address is loaded into the instrument.
H The instrument is powered on and connected to the LAN.
