Introduction
Zilog’s Ethernet Smart Cable, part number ZENETSC0100ZACG, allows you to connect
Z8 Encore!®, Z8 Encore! XP®, ZNEO™ and eZ8 0A c cla im !® development boards to a
Zilog Developer Studio II (ZDS II) 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 ZDS II v4.10.0 or later for Z8 Encore!, eZ80Acclaim!, or ZNEO. To
determine ZDS II requirements for your host system, refer to the quick start guide for
your specific development kit. The latest version of ZDS II is availa ble as a free down -
load from the Zilog Store.
•An available 10/100 Mbps Ethernet connection.
If you are using ZDS II – eZ80Acclaim! versions earlier than 4.10.0, see the
Using the Ethernet Smart Cable on ZDS II – 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 Et hernet 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 ch ange th e cable’s factory default settings, fol low 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 5 V DC power supply to th e Et hernet 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 connec tio n. Th e green activity LED on the Ethernet Smart Cable RJ-45
connector flickers, indicating network activity.

Connecting to the Target Board
Attach one end of the six-conductor ribbon cable to the Smart Cable six-pin DBG connec-
tor, as shown in Figure 1 on page 3. Attach the free end of the ribbon cable to the connec-
tor on the target board. Ensure that pin 1 on the ribbon cable (indicated by the dark stripe)
is aligned with pin 1 on the target connector. To learn more about connecting the Ethernet
Smart Cable to your target board, refer to the eZ80Acclaim! Design for Debug Technical
Note (TN0035) or the Z8 Encore! Design for Debug Technical Note (TN0036).
Using the Ethernet Smart Cable on ZDS II –
eZ80Acclaim! Versions Earlier than 4.10.0

when configured for DHCP.
1. Download the ESCScan utility installation file from the Zilog Store; simply click the
Downloadable Sof tware category, in which you’ll find ES CScan listed as Product ID
SD0012.
2. Run the installation file to install it to your local drive.
3. Run the escscan.exe application file from the installation directory; it will appear
similar to the example screenshot shown in Figure 8.

4. Note the IP Address. If you have several Ethernet Smart Cables connected to the net-
work, an IP address will be shown for each particular Ethernet Smart Cable’s MAC
address.
5. Press any key to exit the utility.
6. You must use the IP address determined in Step 4 when configuring ZDS II; simply
navigate via ZDS II Project → Settings → Debugger → Configure ZPAK II → IP

Troubleshooting Tips
If a hardware failure is suspected, contact support.zilog.com for assistanc e. However,
before submitting a problem report to Zilog Customer Support, follow the instructions in
this section.
ZDS II Cannot See the Ethernet Smart Cable
If ZDS II cannot detect the Ethernet Smart Cable, try the following workarounds:
•Remove power from the Ethernet Smart Cable, wait five seconds, then reapply power.
Refresh the list of available smart cables. The Ethernet Smart Cable should now
appear.
•Verify that the Ethernet cable you are using is the correct type. (If you are connecting
the Ethernet Smart Cable directly to a PC, you must use a crossover cable. Do not use
a crossover cable to connect the Ethernet Smart Cable to a hub or standard Ethernet
connection.)
•Verify that UDP port 3000 is open in your local firewall. The ZDS II software uses
UDP port 3000 to search for Ethernet Smart Cable IP addresses and requires access to
that port through your lo cal firewall. After the port is open, ZDS II should then be able
to identify the IP address assigned to the Ethernet Smart Cable by your DHCP server.
