Restoring the factory settings manually

Requirement
The communications module has been disconnected from the power supply.
Procedure
Proceed as follows to restore all settings to factory defaults using the reader interface:
1. Create a wire jumper.
2. Use the jumper to connect pins 4 (RxD) and 7 (TxD) of the reader X21 interface with one
another.
Figure 10-5
3. Connect the communications module to the power supply.
4. Wait until all LEDs flash for a few seconds, briefly light up continuously, and then flash
again.
5. Remove the jumpers.
6. Wait until the "RUN" LED is continuously lit in green.
Result: The communications module is reset to its original factory settings.
Note that restoring to factory settings assigns the factory-set IP address to the
communications module. Because the IP address is discarded, it is possible that the
connection between the WBM and browser is lost. You can only recognize when the restore
process is completed based on the "RUN" LED. After restoring, the communications module
is restarted. The communications module is ready for operation when the "RUN" LED is
lit/flashes green.
After restarting the communications module, you may have to assign a new IP address or a
new device name to the communications module.
