
set the serial port settings to 115200 bps (at the very top of LumaConf , the speed for
your COM port, not the settings of the modem)

click "Firmware update". A new dialog opens (see Figure 2).

switch on power to the modem (or plug it back in).

Now, an entry should appear under "Devices". On the right-hand side are a few options,
you can ignore most of them.

for RS232 operation: make sure that under "Firmware", the entry "LUMA500ER - RS232
<…>" is selected

for RS485 operation: make sure that under "Firmware", the entry "LUMA500ER – RS485
<…>" is selected

click "write Flash"

wait until the progress bar reaches 100%. If it doesn't go through, click "Write Flash"
again until it does complete.

click "Start application". You should now be able to connect to the modem again as
described above. Verify that the modem settings are still correct - they should carry
across firmware updates in general, but bigger updates may invalidate the settings and
revert to factory defaults.
