User Manual
ST7-EMU3
series emulator
Introduction
Thanks for choosing ST7! This manual will help you set up and start using your ST7-EMU3
emulator.
The ST7-EMU3 emulator is the latest generation of ST7 emulators. In combination with the
ST7 debugging and programming software, it gives you unprecedented control of
application development - from building and debugging your applications to programming
your ST7 microcontroller.
The ST7-EMU3 emulator gives you start-to-finish control of application development by
providing you with emulation and in-circuit communication (ICC) configurations. The ST
Micro Connect box is your common hardware interface for emulation and in-circuit
debugging and programming.
In the emulation configuration, your emulator’s probe and ST7 Visual Develop (STVD7)
software allow you to build and debug your application software. This configuration gives
you the most complete range of debugging features, including advanced breakpoints and
performance analysis.
In the in-circuit communication configuration, the ICC Add-on and STVD7 allow you to
debug your application while it runs on your ST7, and to program your ST7 microcontroller
with ST7 Visual Programmer (STVP7).

2.2 Quick set up for emulation configuration
1. Connect your PC to your ST Micro Connect box via parallel, USB or Ethernet port. For
more details refer toChapter 3: Connectivity on page 9.
For Ethernet connections, you must assign your ST Micro Connect box an IP address.
For instructions refer to Section 3.3: Ethernet connection on page 12.
Caution: Before connecting your emulator and your application board, make sure that both your ST
Micro Connect box and the application board are powered OFF.
2. Fasten ferrite clips to the 80-wire flat cables connecting the ST Micro Connect box to
your EMU3 probe (see Figure 4).
3. Connect your application board to the EMU3-probe. You can use the emulator without
connecting to your application board. For details about connecting to your application
board refer to your ST7xxxx-EMU3 Probe User Guide provided with your emulator.
Caution: Never have your application board powered on while the emulator is powered off—this can
cause serious damage to the emulator.
4. Connect the power supply to your ST Micro Connect box. For power supply
information, refer to Section 4.3.3: Power supply on page 19.
5. Power up your ST Micro Connect box.
6. Power up your application.
Caution: You must always power up your emulator and your application board before running your
application executable in STVD7. Doing otherwise will result in an erroneous emulation.

2.3 Quick set up for in-circuit communication configuration
1. Connect your PC to your ST Micro Connect box via the parallel or USB ports. Ethernet
is not supported for in-circuit debugging and programming.
For more details refer to Chapter 3 on page 9.
Caution: In order to use the ICC Add-on you must design your application board with an HE10
connector linked to the microcontroller in your application. The pins connected to the HE10
connector must use a signal voltage of 3.3 or 5 V. For more information refer to Section 5.2:
ICC connection requirements on page 25.
2. Select the voltage (3.3 or 5 V) with the selector switch on the board of your ICC add-on.
For more information on voltage specifications, refer to Section 5.3: ICC Add-on on
page 28.
3. Plug the ICC Add-on into the ‘Ext Link’ on your ST Micro Connect box.
4. Plug the ICC Add-on into the HE10 connector on your application board.
5. Power up your ST Micro Connect box.
6. Power up your application.

3 Connectivity
The ST Micro Connect box provides three possible connections to the host PC:parallel port,
USB and Ethernet. The type of connection that you use will be determined, in part, by the
configuration you choose for your EMU3 emulator.
In the in-circuit communication configuration, you can use either the USB or the parallel
port. Ethernet is not supported in this configuration. In the emulation configuration you can
use the Ethernet, USB or parallel port.
When you start your emulation, in-circuit debugging or in-circuit programming sessions, you
will have to set the connection type in STVD7 or STVP7. In STVD7, set the port in the
Debug Instrument Settings window (Debug Instrument>Target Settings). When
programming your ST7 with STVP7, set the port in the Configuration window
(Configure>Configure ST7 Visual Programmer). For more information refer to your
software's online help.
The following sections provide you with information about supported connections, as well as
how to connect your PC via:
●Section 3.1 – Parallel port
●Section 3.2 – USB port
●Section 3.3 – Ethernet port
3.1 Parallel port
Your EMU3 emulator supports the parallel port connection modes listed in Table 1, when
using either the emulation or the in-circuit communication configurations.
Table 1. Supported parallel port connection modes

In-circuit Communication Windows®98,Millennium,
NT®4, 2000, XP ECP(1), Bidirectional, Compatible, SPP,
Nibble, Centronics or EPP.

3.1.1 Connecting to the parallel port
Figure 8. Parallel port connection between ST Micro Connect box and PC
To connect your emulator to your PC, connect the end of the parallel cable with the ferrite to
the ST Micro Connect’s rear panel 25-pin SUB-D connector (see Figure 8). Connect the
other end of the parallel cable to one of the PC’s parallel ports (LPT1 or LPT2). Be sure to
use the parallel cable provided with your emulator. Using a longer parallel cable may cause
emulator malfunctions. The use of switch boxes between the parallel port connector of your
PC and the emulator is not recommended.
3.1.2 Changing the parallel port set up
Under certain circumstances, you may receive the following error message:
Connection Error (LPT1/LPT2): Interconnection failure. Verify your
input/output cable.
This may mean that the setup of the LPT1 or LPT2 port on your PC is not compatible with
the emulator. To set up the port correctly:
1. Shut down and restart your PC in order to enter the BIOS setup.
2. Follow the messages displayed on the screen and when prompted, press the key
required to enter the BIOS setup (usually a function key or the ESC key).
3. Select the parallel ports menu (this may be listed under I/O ports).
4. Change the Mode of the LPT port that you have chosen for your ST Micro Connect box
(i.e. either LPT1 or LPT2) to one of the compatible modes listed in Table 1 on page 9.
5. Save your changes and exit the BIOS setup.
