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
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.
