Copyright ©2012 Zilog®, Inc. All rights reserved. www.zilog.com 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 (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 available 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. Note: Ethernet Smart Cable User Manual UM020705-1012

UM020705-1012 Page 2 of 13 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. Development Board System Clock Power Supply Current*Minimum Maximum Minimum Maximum Z8 Encore! 32 kHz 20 MHz 2.7 V 3.6 V 2 mA ZNEO 10 kHz 20 MHz 2.7 V 3.6 V 2 mA eZ80Acclaim! 5 MHz 50 MHz 3.0 V 3.6 V 2 mA Note: *Add this Ethernet Smart Cable current as a requirement for your target’s power supply. Note:
  • 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 Ca ble to an Ethernet connection. 2. Connect the 5 V 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.

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. Note: Note:

  1. Use the Ethernet crossover cable supplied with the Ethernet Smart Cable to connect

the Ethernet Smart Cable to the host PC’s Ethernet port.

  1. Connect the 5 V DC power supply to the Ethernet Smart Cable power connector. As a

RJ-45 connector flickers, indicating network activity.

  1. On the host PC, open the Windows Control Panel and double-click the Network and

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 determ ined in Step 4 when configuring ZDS II; simply navigate via ZDS II Project → Settings → Debugger → Configure ZPAK II → IP Address. For more information about this utility, refer to its readme.txt document. Troubleshooting Tips If a hardware failure is suspected, contact support.zilog.com for assistance. 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 local 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.
