TROUBLESHOOTING
The CME12B32 board is fully tested and operational before shipping. If it fails to function properly, inspect the board for
obvious physical damage first. Ensure that all socketed IC devices are properly seated in the their sockets.
The most common problems are improperly configured communications parameters and attempting to use the wrong
COM port (on the PC AND on the development board). Verify that your communications port is working by substituting a
known good serial device, or by doing a loop back diagnostic. Verify that no other devices are conflicting with the port
(such as a mouse, modem, etc.).
Check your hardware configuration jumpers and switches. Verify the power source. You should measure 9 volts between
GND and +9V test point pads on the board near J1. If no voltage is found, verify wallplug connections to 115VAC outlet
and power connector. Disconnect all external connections to the board except for COM1 to the PC and the wall plug.
Follow these steps in the order given:
Troubleshooting Steps
1. Visual Inspection
2. Verify that all jumpers are set properly.
3. Verify power by checking for +9 volts between GND and +9V test point pads.
4. Verify the Monitor EEPROM for proper installation (no bent pins) and proper jumper settings for the device
5. Re-Check the communications parameters.
6. Disconnect any peripheral devices including display and keyboard.
7. Make sure that the RESET line is not being held low.
8. Verify presence of 8MHz sine wave on the crystal if possible.
9. Please check off these steps and any others you may have performed before calling so we can better help
used.
