INTRODUCTION
Before contacting a ZiLOG representative or submitting a Problem
Report, please follow these simple steps. Also, check the Precautions and
Limitations sections in the Product Information document included with
the emulator to eliminate other possible known problems. If a hardware
failure is suspected, contact a local ZiLOG representative for assistance.
ERROR OPENING SERIAL PORT
If the initial ZiLOG screen is not appearing after selecting the COM port
and the screen message displays Time-out while reading:
1.
Check the RS-232C cable connection and communication port
selection in ZDS. See Select the ICEBOX on page 23 for more
information on how to configure the host PC’s port.
2.
Reset the emulator and ZDS.
3.
Try connecting another cable.
4.
Check if transmit/receive signals need to be swapped.
On some DB9 connectors for the COM ports, the transmit/receive
signal may be swapped and a Null Modem adapter may be
required.
5.
Ensure that the power supply is connected, is turned on, and power is
available.
6.
Ensure that the power supply is set at the correct voltage.
