5.1 Resetting the device
If, for some reason, the module needs to be reset to factory settings, there are two methods
available: hardware reset and software reset.
5.1.1 Hardware reset
The reset button allows resetting the device without the use of a PC.
To force a hardware reset:
1. With the device powered off, press and hold the reset button. Apply power and hold the
reset button for at least five seconds. Reinitializing the module and firmware reset may
take some time. Do not disconnect from power (see Section 1.1, “Structure” for the
location of the reset button on the GW PN/ASCII...).
2. After a successful reset, the module returns to the factory default address
(192.168.254.254).
5.1.2 Software reset
To force a software reset:
1. Start the web server and navigate to the “Device Maintenance/Restore Defaults” page.
2. Click the check box on the page.
3. Click the “Apply Changes” button.
4. After a successful reset, the module returns to the factory default address
(192.168.254.254).
