TROUBLESHOOTING
Communication Failure
If communication to the ADE7953 is not successful, the warning
message shown in Figure 20 is displayed.
Figure 20. Communication Unsuccessful Message
This message indicates that the ADE7953 did not respond
and the communication timed out. The communication port
on the PC must be reset to restore communication to the
ADE7953. When the OK button is clicked, the Clear Port
window appears (see Figure 21).
Figure 21. Clear Port Window
When the Clear Port window appears, press the S1 push-button
located above the PC connection on the ADE7953 interface port
to reset the PC COM port (see Figure 1). After completing this
action, click DONE in the Clear Port window.
Before continuing with the evaluation of the ADE7953, the
reason for the communication failure should be investigated.
After the COM port is cleared, the window shown in Figure 22
is displayed to provide some possible reasons for the failed
communication.
Figure 22. Error Debug Window
After clicking OK, click EXIT in the main window (see Figure 7).
To troubleshoot the problem, verify the following items:
• The selected COM port is correct in the main window (see
Figure 7).
• The currently configured communication mode is correct
in the main window (see Figure 7).
• The correct jumpers are installed for the selected commu-
nication interface (see Table 1).
Incorrect Register Readings
If the data read back from the ADE7953 registers is always
FFFF, a possible cause is that the ADE7953 is not correctly
powered. Ensure that a 3.3 V supply has been supplied to the
ADE7953, as described in the Powering Up the Evaluation
Board section.
