Preface
These instructions describe how to install, set up, and test the
TDS2CM, TDS2HM, and TDS2MM Extension modules. This
manual presumes that you understand how to operate the TDS
200-Series oscilloscope.
Conventions
This manual uses the following conventions:
Labeled oscilloscope panel buttons are shown in the manual in all
uppercase letters. For example: UTILITY, HARDCOPY.
On-screen menu items are shown in the manual with the first
letter of each menu word in upper case. For example: Options,
Recall Factory.
A list of panel buttons, separated by the symbol, represents the
order in which to push the listed buttons. For example,
UTILITY Options RS-232 means that you first push the
UTILITY panel button, then push the side menu button to the
right of the Options menu item, and then push the side menu
button to the right of the RS-232 menu item.

Preface
TDS 200-Series Extension Module Instructions v
Command Entry
Follow these general rules when entering oscilloscope commands
over the RS-232 or GPIB bus:
You can enter commands in upper or lower case.
You can abbreviate many oscilloscope commands. These
abbreviations are shown in uppercase letters. For example, the
command ACQuire:NUMAVg can be entered simply as
ACQ:NUMAV or acq:numav.
You can precede any command with white space characters.
White space characters include any combination of the ASCII
control characters 00 through 09 and 0B through 20 hexadecimal
(0 through 9 and 11 through 32 decimal).
The oscilloscope ignores commands that consist of just a
combination of white space characters and line feeds.

TDS 200-Series Extension Module Instructions 1
Getting Started
This chapter describes important module and oscilloscope dependen-
cies, and how to install and check the TDS 200-Series extension
modules.
Read Me First
NOTE. Read the following text before installing your module. To
display oscilloscope and module firmware version numbers, press
UTILITY System Status Misc.
TDS2MM and TDS 200-Series
The TDS2MM Module only operates on TDS 200-Series oscillo-
scopes with firmware version v1.06 and greater. Contact Tektronix
for information on how to upgrade your TDS 200-Series oscilloscope
firmware.
Seiko Printer Support
Seiko printer support (DPU411, DPU412) is only available with the
following firmware configurations:
Module and firmware TDS 200 firmware
TDS2HM v1.00 and greater v1.09 and greater
TDS2CM v1.04 and greater 1v1.09 and greater

Removing and Installing Modules
The following sections describe how to safely remove and install a
module on your oscilloscope.
PreventingElectrostatic Damage
CAUTION. Electrostatic discharge (ESD) can damage components in
the extension module and the oscilloscope. To prevent ESD, follow
the steps below when installing, removing, or handling the extension
modules:
1. Always turn off the oscilloscope before removing or installing
extension modules.
2. Handle extension modules as little as possible.
3. Transport and store extension modules in a static-protected bag
or container.
4. Do not slide the extension module over any surface
5. Wear a grounded antistatic wrist strap to discharge the static
voltage from your body while installing or removing an extension
module from the oscilloscope.
6. Do not touch the oscilloscope extension module connector pins.
7. Do not use any devices capable of generating or holding a static
charge in the work area where you install or remove extension
modules.
8. Avoid handling modules in areas that have a floor or work-sur-
face covering capable of generating a static charge.
9. Make sure that you install the extension module cover after you
remove an extension module.

Removing an Extension Module
CAUTION. Electrostatic discharge (ESD) can damage components in
the extension module and the oscilloscope. To prevent ESD, follow
the steps on page 3 when installing, removing, or handling the
extension modules.
After removing a module, install the dummy module cover to protect
the contact pins.

Checking Module Installation
To check that the extension module is correctly installed, turn on the
oscilloscope. The power–up screen should include the message
”Extension Module Passed”. If the oscilloscope does not recognize
the extension module at power-up, do the steps in Troubleshooting
Module Installation below.
Troubleshooting Module Installation
If the oscilloscope does not recognize the extension module at
power-up, do the following steps:
1. Turn off the oscilloscope.
2. Follow the ESD precautions listed on page 3.
3. Disconnect all cables from the extension module.
4. Remove the extension module (refer to page 4).
5. Examine the oscilloscope option connector for bent, broken, or
missing pins. If any pins are bent, carefully straighten them out.
6. Reinstall the extension module onto the oscilloscope.
7. Turn on the oscilloscope. If the oscilloscope still does not show
the module installed, contact the nearest Tektronix service center.

TDS2HM Hard Copy Module
The TDS2HM Module lets you print the oscilloscope screen data on
a printer. This chapter describes how to set up and test the TDS2HM
Hard Copy Extension Module. This information also applies to the
hard copy portion of the TDS2CM Communications Module and the
TDS2MM Measurement Module.

Hard Copy Setup
To setup the TDS2HM Module, do the following:
1. Turn on the oscilloscope.
2. Push UTILITY Options Hard Copy Setup.
3. Push the menu button next to the menu item to change the
settings to match those of your printer device. The following
table lists the settings you can change.
The oscilloscope stores these settings until you change them.
Turning off the oscilloscope does not erase these settings.

Testing the Hard Copy Port
1. If you have already connected the oscilloscope to a printer, go to
step 4.
2. Turn off the oscilloscope and the printer.
3. Connect the oscilloscope to the printer using the appropriate
cable.
4. Turn on the oscilloscope and the printer.
5. If you have not done so already, do the hard copy setup
appropriate for your extension module. Refer to page 8.
6. On the oscilloscope, push the HARDCOPY button. The printer
should begin printing a copy of the oscilloscope screen after a
few seconds.
Printing an Oscilloscope Screen
To print the screen data, push the HARDCOPY button. The
oscilloscope takes a few seconds to capture the screen data and send
it to the printer. The printer then begins printing a copy of the
oscilloscope screen. Your printer settings determine how long it
takes to print the screen data.
