Introduction
The Ethernet Smart Cable, ZENETSC0100ZACG, allows you to connect the Z8 Encore!®,
ZNEO ™, or eZ80Acclaim!®development board to a ZiLOG Developer Studio II (ZDS
II) host-system using an Ethernet connection.
This user manual provides instructions for installing Ethernet Smart Cable hardware.
Instructions are also provided for Ethernet-equipped host PCs that are not network-con-
nected. Once the Ethernet Smart Cable is connected, you can proceed with debugging as
described in the development kit documentation.

Installing the Ethernet Smart Cable
The Ethernet Smart Cable is optimized for use on an Ethernet network in which a 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 Ehternet Smart Cable’s factory default settings are:
•DHCP enabled
•IP address = 192.168.1.50 (will change if DHCP server is available to assign an
address)
•Subnet mask = 255.255.255.0
•Gateway = 192.168.1.254
•No password required
You can change the cable’s factory default settings by following the instructions in
“Changing the Default Settings of the Ethernet Smart Cable” 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, you will have to connect the Ethernet Smart Cable to a stan-
dalone PC configured as described in “Connecting the Ethernet Smart Cable
Directly to a Host PC” below.
Connecting the Ethernet Smart Cable to a DHCP-Based Network
You will need (a) an active Ethernet connection, such as from an Ethernet hub, and (b) a
standard CAT-5 Ethernet cable.
1. Connect the Ethernet Smart Cable to an Ethernet connection.
2. Connect the 5VDC power supply to the Ethernet Smart Cable power connector.
The green PWR and RUN LEDs illuminate (see Figure 1). The green link LED on the
Ethernet Smart Cable RJ-45 cable (see Figure 2) will illuminate, indicating a live
Ethernet connection. The green activity LED on the Ethernet Smart Cable RJ-45 con-
nector (see Figure 2) will flicker, indicating network activity.

3. Start ZDS II.
4. Open one of the projects listed in the samples directory of your ZDS II installation.
5. Select Project –› Settings. The Project Settings window appears.
6. Select the Debugger tab.
7. In 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. Check the box 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.
You can now connect the target board to the Ethernet Smart Cable as described in “Con-
necting to the Target Board” on page 11.
Connecting the Ethernet Smart Cable Directly to a Host PC
When using a host PC that is not network-connected, you must configure the PC as fol-
lows to connect it to the Ethernet Smart Cable.
The following instructions are for the MS Windows XP platform. If your Win-
dows operating system is different, please refer to your MS Windows OS
online help for details.
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 5VDC power supply to the Ethernet Smart Cable power connector.
The green PWR and RUN LEDs illuminate (see Figure 1). The green link LED on the
Ethernet Smart Cable RJ-45 cable (see Figure 2) will illuminate, indicating a live
Ethernet connection. The green activity LED on the Ethernet Smart Cable RJ-45 con-
nector (see Figure 2) will flicker, indicating network activity.
4. On the host PC, open the Windows Control Panel and double-click the Network and
Internet Connections icon. The Network Connections dialog box appears (Figure 3).

8. Enter an IP address of 192.168.1.21 and a subnet mask of 255.255.255.0. These
values place the PC on the same network as the Ethernet Smart Cable, and do not con-
flict with the IP address of the Ethernet Smart Cable.
9. Click OK and restart the PC.
10. The PC is now ready to communicate with Ethernet Smart Cable via the ZDS II soft-
ware.
11. The default IP address of the Ethernet Smart Cable unit is 192.168.1.50.
Changing the Default Settings of the Ethernet Smart Cable
The Ethernet Smart Cable is equipped with a web interface that allows you to change its
default settings.
To access the Ethernet Smart Cable web interface, you must know the cable’s IP address,
which you can obtain from ZDS II in the ZDS II Project Settings window (see Steps 5
through 9 on page 4).
