13.2 Loading of a firmware file (Update)
-
The REX 200/250 must be ready for operation. Apply supply voltage -> After
approx. 70 seconds the PWR and RDY LEDs light up
-
Insert the USB stick with the firmware file into the USB port of the REX 200/250
-
As soon as the firmware file is detected, the FC1 and FC3 LEDs flash orange
(after approx. 5 seconds)
-
Insert the supplied tool (SIM card ejector) into the opening below FCN. Press the
FCN key and hold it until the FC2 LED flashes orange (about 2 seconds)
-
Release the FCN button
-
The firmware is transferred from the USB stick to the router
(Duration approx. 15 seconds)
-
As soon as the FC2 LED goes out, the transfer is complete
-
A reboot of the REX 200/250 is performed automatically and the process is
complete when the PWR and RDY LEDs are lit solid.
14. Alternative configuration without
myREX24-V2 portal
If you want to use the REX 200/250 without our mediation server "myREX24 V2",
you can also use another OpenVPN software or e.g. set up the IPsec encryption
embedded in your hardware. If you have selected the selection for the classic router
in the "First Start" screen, you can reach the corresponding step by step configurator
of the web interface via the menu item "Wizards" in the upper right corner.
For the aforementioned parameterization options are appropriate Documents
with application examples under www.helmholz.com free of charge available for
download.
Important:
An interruption of the supply voltage during the data transfer Transferring
from the USB stick can put the router in an undefined state! The firmware to be transfer-
red must be stored in the top directory (root) of a FAT / FAT32 formatted USB stick. The
firmware file "image.swux" must not be renamed.
Note:
If both the firmware and a myREX24 portal configuration are found on the USB
stick, the firmware is always first recognized by the REX 200/250 (Fc1 + Fc3 flashes).
If you don’t press the FCN button within 10 seconds, the REX 200/250 changes to the
configuration file (Fc1 + Fc2 flash). If you here too don’t react within 10 seconds,
the router once again reverts to the normal mode.
