Restoring the factory settings for the hardware

Requirement
The communication 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 (wire diameter ≤ 0.8 mm).
2. Use the jumper to connect pins 4 (RxD) and 7 (TxD) of the reader X21 interface with one
another.
Figure 9-3
3. Connect the communication 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 was reset to its original factory settings.
Note that restoring the factory settings also resets the IP address of the communications
module. With the factory settings, the IP address is obtained via a DHCP server.
After restarting the communications module, you may have to assign a new IP address or a
new device name to the communications module.
