Problems with the direct connection to a gigabit network device
Problem Solution
When a device is connected directly to
the DL2 Datalogger using a gigabit net-
work adapter, no network connection
is established.
Note
Not all network interface cards
support 10 MBits/s half-duplex
communication.
Î Alternative A: Interconnect a
100 MBits switch between the two
devices.
Î Alternative B: Set the network con-
nection settings of your computer
to 10 MBits/s half-duplex.
User password not available
Problem Solution
The user password is not available. When the user password is not avail-
able, the DL2 Datalogger has to be re-
set to its factory settings in order to
regain access to the Web interface.
Note
When the DL2 Datalogger is
reset to its factory settings, all
logged data and the congura-
tion will be erased. In order to
save the logged data, they can be
exported onto an SD card be-
fore a reset.
After a reset, the device has to
be added to VBus.net again.

over SD card, page 23.
