12. Restoring the REX 300 router to its default settings
In order to reset the REX 300 to the factory settings, the following steps are neces-
sary:
- Switch on REX 300.
- Wait until the SF LED lights up.
- Press the Dial Out button and hold it down for about 10 to 15 seconds until the
TxD LED shows a green light
- BrieypresstheDialOutbuttonagain;theRxDLEDwilllightup.
- BrieypresstheDialOutbuttononceagain;theTxDLEDwillshowanorange
light.
- Finally, press the Dial Out button one last time.
Youhavenowdeletedtheentireconguration.YourREX300unithasbeenrestored
toitsdefaultsettingsandcanbereconguredatthispoint.
Important: The IP address of the REX 300 LAN interface is reset to 192.168.0.100/24.
13. FirmwareupdateusingaUSBashdrive
Note: The rmware le must be stored in the root directory of your USB ash drive. In
addition, no valid conguration le may be found in the root directory when carrying
out this action. A disruption of the supply voltage during the transfer can switch the
router to an undened status.
- LoadthermwareleontoastandardFAT-formattedUSBashdrive.
- Switch the REX 300 on and wait until the boot process is completed (Rdy & ON
LEDs are lit up continuously).
- Plug the USB stick into the appropriate USB terminal on the REX 300.
- WaituntiltheRxDLEDbeginstoash.
- PresstheDialOutbuttonandholditdownuntiltheTxDLEDashes.TheREX300
hasrecognizedthermwarele.
- Release the Dial Out button.
- IfaUSBashdrivewithvalidrmwareisfound,thecongurationwillbetrans-
ferredfromtheashdrivetotherouter.Duringtransmission,theTxDLEDashes.
- The RDY LED and the ON LED will show a solid light as soon as the process is com-
plete.ArestartoftheREX300isnotrequired.

IfyouwouldliketousetheREX300withoutour"myREX24"cloudserver,youcan
also use other OpenVPN software or, for example, set up the IPsec encryption em-
bedded in your hardware.
Ifyouhaveactivatedtheselectionfortheclassicrouterinthe"FirstStart"screen,you
reachthecorrespondingstep-by-stepconguratorofthewebinterfacethroughthe
"Assistants"menupointinthetoprightcorner.
Note: Manual conguration is also possible. We provide detailed installation examples
