Introduction
ZiLOG’s Ethernet Smart Cable (ESC), ZENETSC0100ZACG, allows you to connect the
Z8 Encore!®, Z8 Encore! XP®, 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 ESC hardware. Instructions are also
provided for Ethernet-equipped host PCs that are not network-connected. Once the ESC is
connected, proceed with debugging as described in the development kit documentation.
Kit Contents
For details on kit contents, refer to Ethernet Smart Cable Packing List (PAK0019).
Software and Hardware Requirements
The software and hardware requirements are described below:
•A host PC with ZDS II v4.10.0 or later for Z8 Encore!, eZ80Acclaim!, or ZNEO. For

Installing the Ethernet Smart Cable
The ESC 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 ESC to a DHCP-based network, or directly to an
Ethernet-equipped host PC.
The ESC’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
Follow the instructions in Changing the Default Settings of the ESC on page 8 to change
the cable’s factory default settings.
When a DHCP server is unavailable, the ESC defaults to using IP address
192.168.1.50. If your network uses static IP addresses on a different subnet,
connect the ESC to a standalone PC configured as described in Connecting the
ESC Directly to a Host PC below.
Connecting the ESC to a DHCP-Based Network
You need the following to connect the ESC to a DHCP-based network:
•An active Ethernet connection, such as from an Ethernet Hub.
•A standard CAT-5 Ethernet cable.
Follow the steps below to connect the ESC:
1. Connect the ESC to an Ethernet connection.
2. Connect the 5 V DC power supply to the ESC power connector.
eZ80Acclaim! 5 MHz 50 MHz 3.0 V 3.6 V 2 mA
*Add this current for ESC requirement on your target's power supply.

9. Click the OK button in the Project Settings window. Your project is now configured
to run with the newly installed ESC.
Now connect the target board to the ESC as described in Connecting to the Target Board
on page 11.
Connecting the ESC Directly to a Host PC
When using a host PC that is not network-connected, configure the PC as follows to
connect it to the ESC.
The following instructions are for the MS Windows XP platform. If your
Windows operating system is different, refer to MS Windows OS online help
for details.
Follow the steps below to connect the ESC to a Host PC:
1. Power on your host PC before proceeding.
2. Use the Ethernet crossover cable supplied with the ESC to connect the ESC to the host
PC’s Ethernet port.
3. Connect the 5 V DC power supply to the ESC power connector.
The green PWR and RUN LEDs illuminate. The green link LED on the ESC RJ-45
cable (see Figure 1 on page 3) illuminates, indicating a live Ethernet connection. The
green activity LED on the ESC RJ-45 connector flickers, 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 (see
Figure 2 on page 5).

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 ESC, and do not conflict with the IP
address of the ESC.
9. Click OK and restart the PC.
The PC is now ready to communicate with ESC via the ZDS II software. The default IP
address of the ESC unit is 192.168.1.50.
Changing the Default Settings of the ESC
The ESC is equipped with a web interface that allows you to change its default settings.
To access the ESC web interface, you must know the cable’s IP address, which can be
obtained from ZDS II in the ZDS II Project Settings window (see step 5 through step 9 on
page 3).

Restoring the ESC Factory Settings
Follow the steps below to restore the ESC factory settings:
1. Locate the reset switch access hole in the side of the ESC housing.
2. Using a straightened paper clip, press and hold the reset switch for six seconds. The
Run LED will extinguish while the switch is pressed, and will illuminate again after
factory settings are restored.
Connecting to the Target Board
Attach one end of the six-conductor ribbon cable to the Smart Cable six-pin DBG
connector (see Figure 1 on page 3). Attach the free end of the ribbon cable to the
connector 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. For further information on connecting
the ESC to your target board, refer to either eZ80Acclaim! Design for Debug Technical
Note (TN0035) or Z8 Encore! Design for Debug Technical Note (TN0036).
Troubleshooting Tips
If a hardware failure is suspected, contact a local ZiLOG representative for assistance.
Before submitting a problem report to ZiLOG Customer Support, follow the instructions
below:
ZDS II Cannot See the ESC
If ZDS II cannot see the ESC:
•Remove power from the ESC, wait five seconds, then reapply power. Refresh the list
of available smart cables. The ESC must now appear.
•Verify that the Ethernet cable you are using is the right type. (If you are connecting the
ESC directly to a PC, you must use a crossover cable. Do not use a crossover cable to
connect the ESC 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 ESC IP addresses and requires access to that port through
your local firewall. Once the port is open, ZDS II should then be able to identify the IP
address assigned to the ESC by your DHCP server.

zds2.asp under the miscellaneous section.
2. Run the installation file to install it to your local drive.
3. Run the escscan.exe application from the installation directory. You will see the
following example screenshot (see Figure 8).
Figure 8. escscan.exe Application Screenshot
4. Make a note of the IP Address. If you have several ESC connected to the network, the
IP address will be shown for each particular ESC’s MAC address.
5. Press any key to exit the utility.
6. The IP Address is the one you have to use when configuring the ZDS II Project→
Settings→Debugger→Configure ZPAK II→IP Address. For more information on
this utility, refer to readme.txt document.
