1. Introduction
Thank you for purchasing the ADSP-218x Family EZ-ICE®serial port
emulation system. The Analog Devices EZ-ICE serial emulator system
provides state-of-the-art emulation and support for the Analog Devices
218x Family of DSPs. It provides a controlled environment for observing,
debugging, and testing activities in a target system by connecting directly to
the target processor through the emulation interface port.
Features of the ADSP-218x Family EZ-ICE system are as follows:
•High speed RS-232 serial port support.
•Runs natively under Windows 9x, NT 4.0 and Windows 2000
•Emulation for the Analog Devices ADSP-218x family DSP’s.
•Support for 2.5, 3.3, and 5.0 volt target processors.

2. Requirements
The minimum PC host requirements for the ADSP-218x Family EZ-ICE
are as follows:
•Pentium 166 MHz or better
•32 megabytes of RAM memory
•Windows 9x, NT 4.0 or Windows 2000 operating system
•One RS-232 compatible serial port

3. Configuration and Installation
This section provides all of the information required to install the ADSP-
218x Family EZ-ICE serial port emulator into your PC. To install the
emulator software please refer to the VisualDSP® Software User’s
Guide.
3.1 Installation
The ADSP-218x Family EZ-ICE is connected to your development
platform via the serial port and requires its own separate power connection.
In general you should be able to use the following instructions.
F
Important! The Analog Devices ADSP-218x Family
DSP emulator, contains ESD (electrostatic discharge)
sensitive devices. Electrostatic charges readily
accumulate on the human body and equipment, and can
discharge without detection. Permanent damage may
occur to devices subjected to high-energy discharges.
Proper ESD precautions are recommended to avoid
performance degradation or loss of functionality.

3.2 Configuring the ADSP-218X Family EZ-ICE Pod
The ADSP-218x Family EZ-ICE pod contains two user accessible
switches. One push button switch performs a hardware reset and is
accessible by using a small push stick. A 3-position slide switch is used to
set the target voltage levels between 2.5, 3.3, and 5.0 volts. There are 3-
voltage indicator LED’s that provide an easy way to check the pod’s target
voltage setting. The LED’s are located on the front cover across from the
reset switch shown in figure 1.

F
Warning! Damage to the ADSP-218x Family EZ-
ICE, or your target system can occur if the voltage
selection switch is set incorrectly. Check your target
system voltage requirements before connecting the EZ-
ICE to the target system and applying power.
3.3 Connecting the Pod to Your Target System
The pod connects to the target processor via a special emulation header.
The target board must be built with an appropriate emulation header, which
is shown in figure 2a. For details on building an EZ-ICE compatible target,
www.BDTIC.com/ADI

see your appropriate 218x family datasheet, the 2100 family users manual,
and EE-Note 34, “Understanding 21xx/218x EZ-ICE Theory of Operation
to Aid in Designing an EZ-ICE Compatible Target.” Please note the
position of the key pin. The key pin should be used as a guide to connect
the pod to the target.
When connecting an unpowered EZ-ICE to an unpowered target:
1. Plug the 14-pin connector into the target board emulation header.
2. Apply power to the target.
3. Apply power to the EZ-ICE.
When connecting a powered EZ-ICE to a powered target:
1. Connect the ground of the EZ-ICE at TP1 (on the emulator header)
to the ground of the target supply.
2. Plug the 14-pin connector into the target board emulation header.
When disconnecting a powered EZ-ICE from a powered target:
1. Maintain the ground of the EZ-ICE at TP1 to the ground of the
target supply.
2. Unplug the 14-pin connector from the target board emulation
header.
3. Disconnect the ground connection.
When disconnecting an unpowered EZ-ICE from an unpowered target, just
unplug the 14-pin connector from the target board emulation header shown
in figure 2b.
