Figure 19. Reset Window

When the RESET ADE7953 button is clicked, a hardware reset

is performed on the ADE7953. All register data is lost and the

part must be reconfigured.

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.
