Introduction
Zilog’s Ethernet Smart Cable, part number ZENETSC0100ZACG, allows you to connect
Z8 Encore!®, Z8 Encore! XP®, ZNEO™and eZ80Acclaim!®development boards to a
Zilog Developer Studio II (ZDSII) host system using an Ethernet connection.
This user manual provides instructions for installing the Ethernet Smart Cable hardware.
Instructions are also provided for Ethernet-equipped host PCs that are not network-con-
nected. After the Ethernet Smart Cable is connected, proceed with debugging as described
in the documentation specific to your development kit.
Kit Contents
To determine the contents of your kit, refer to the Ethernet Smart Cable Packing List
(PAK0019), a paper insert included with your kit.
Software and Hardware Requirements
The requirements for using the Ethernet Smart Cable are:
•A host PC with ZDSII v4.10.0 or later for Z8 Encore!, eZ80Acclaim!, or ZNEO. To
determine ZDSII requirements for your host system, refer to the quick start guide for
your specific development kit. The latest version of ZDSII is available as a free down-
load from the Zilog Store.
•An available 10/100Mbps Ethernet connection.
If you are using ZDSII – eZ80Acclaim! versions earlier than 4.10.0, see the
Using the Ethernet Smart Cable on ZDSII – eZ80Acclaim! Versions Earlier
than 4.10.0 section on page 11.

Supported Target Environments
The supported target environments are described in the following table.
Installing the Ethernet Smart Cable
The Ethernet Smart Cable is optimized for use on an Ethernet network in which a dynamic
host configuration protocol (DHCP) server assigns IP addresses. The following sections
provide instructions for connecting the Ethernet Smart Cable to a DHCP-based network,
or directly to an Ethernet-equipped host PC.
The Ethernet Smart Cable’s factory default settings include:
•DHCP enabled
•IP address: 192.168.1.50 (this address will be different if a DHCP server is available
to assign an address)
•Subnet mask: 255.255.255.0
•Gateway: 192.168.1.254
•No password required
If you need to change the cable’s factory default settings, follow the steps described in the
Changing the Default Settings of the Ethernet Smart Cable section on page 8.
When a DHCP server is unavailable, the Ethernet Smart Cable defaults to
using IP address 192.168.1.50. If your network uses static IP addresses on a
different subnet, connect the Ethernet Smart Cable to a stand-alone PC con-
figured as described in the next section.

Connecting the Ethernet Smart Cable to a DHCP-Based
Network
The following considerations must be determined prior to connecting the Ethernet Smart
Cable to a DHCP-based network:
•An active Ethernet connection must be available, such as from an Ethernet hub
•A standard CAT-5 Ethernet cable must be available
Observe the following steps to connect the Ethernet Smart Cable:
1. Connect the Ethernet Smart Cable to an Ethernet connection.
2. Connect the 5V DC power supply to the Ethernet Smart Cable power connector. As a
result, the green PWR and RUN LEDs will illuminate. The green link LED on the
Ethernet Smart Cable RJ-45 connector illuminates, as shown in Figure 1, indicating a
live Ethernet connection. The green activity LED on the Ethernet Smart Cable RJ-45
connector flickers, indicating network activity.

3. Launch ZDSII.
4. Navigate via the File menu in ZDSII to open one of the projects listed in the samples
directory of your ZDSII installation.
5. Select Project Settings to display the Project Settings dialog.
6. Select the Debugger tab.
7. From the Debug Tool drop-down menu, select EthernetSmartCable.
8. Click the Setup button. Your Ethernet Smart Cable will be listed in the Smart Cables
Available list. Select the checkbox for your Ethernet Smart Cable, then click the OK
button.
If you have more than one Ethernet Smart Cable, you can uniquely identify
them by comparing the MAC address listed in the Smart Cables Available
list with the label on the bottom of the Ethernet Smart Cable.
9. Click the OK button in the Project Settings window. Your project is now configured
to run with the newly installed Ethernet Smart Cable.
10. Connect the target board to the Ethernet Smart Cable as described in the Connecting to
the Target Board section on page 11.
Connecting the Ethernet Smart Cable Directly to a Host PC
When using a host PC that is not network-connected, configure the PC as follows to con-
nect it to the Ethernet Smart Cable.
The following instructions are designed for use on a MS Windows XP plat-
form. If your Windows operating system is different, refer to MS Windows
OS online help for details.
Observe the following steps to connect the Ethernet Smart Cable to a host PC:
1. Power on your host PC before proceeding.

2. Use the Ethernet crossover cable supplied with the Ethernet Smart Cable to connect
the Ethernet Smart Cable to the host PC’s Ethernet port.
3. Connect the 5V DC power supply to the Ethernet Smart Cable power connector. As a
result, the green PWR and RUN LEDs will illuminate. The green link LED on the
Ethernet Smart Cable’s RJ-45 connector illuminates (see Figure 1 on page 3), indicat-
ing a live Ethernet connection. The green activity LED on the Ethernet Smart Cable
